Once installed, the extension adds a new “Snooze” button to the Gmail interface, as shown above. Hit the button, and a drop-down menu appears, enabling you to choose a snooze period from five minutes to four hours, or to be reminded about the email on a specific day or at a specific time:

When the snooze period is up, the extension will then play an alert sound and pop up a desktop notification, reminding you about the email and (optionally) marking the email as unread. In the notification, there are handy links to open the email or to snooze it again:

It’s a simple idea and it’s implemented well. However, it only works on Chrome, so if, like me, you also tend to read your emails on mobile devices it may prove less useful. I’d love to see this as a Labs feature in Gmail itself and have it available on multiple platforms. Note that despite its name, Snooze Your Email for Gmail also apparently works for Yahoo Mail, although I haven’t tried it.

Once installed, Trails stores the text and images that you clip onto pages that it calls “spreads.” These are viewable in a sidebar  (via View->Sidebar->Trails or a keyboard shortcut). You can create as many spreads in your booklet as you like, and they can be can be set up as one-, two- or three-column pages.

Adding content to your booklet is done via some new Firefox context menu items: As you’re browsing, highlight some text or select an image and right-click to select to add it to your booklet. Before text is added to the spread, it pops up in a window giving you the opportunity to edit it. Content can be deleted and edited after insertion on the page, too. Trails automatically puts the URL a particular snippet or text or image came from below each piece of content on the page, as well as recording the time and date that it was clipped on.

Once your booklet is complete, it can be printed, exported in PDF format or published to the Trails Public Library online.

As a note-taking tool, Trails is nowhere as powerful and flexible as more full-featured, multi-user solutions like Evernote or OneNote.  However, it does fit seamlessly into a Firefox-based workflow, and as the booklets that it creates are nicely-formatted and can be exported as a PDF, it makes for a very easy way to share well-presented research with colleagues or clients.

Trails can be downloaded from the Mozilla Add-Ons repository.

• How to Ride the Freemium App Wave to Success

The new View Later functionality is baked into the browser UI. As you can see in the screenshot above, the “View Later” button — a clock icon — sits next to the familiar bookmarking star in the address bar. Clicking that button adds the current page to the user’s View Later list, which can be accessed from the right-hand strip on the browser. The items are displayed as a searchable chronological list; each item is displayed with an excerpt and thumbnail image for easier scanning. From the demo I’ve seen, it’s a very slick implementation:

Unfortunately, the View Later tool currently doesn’t sync with other popular “read later” tools like Instapaper or Read It Later, nor does it have mobile access, which may limit its usefulness. One of the reasons I like Instapaper is its ability to save articles while browsing on my Mac to catch up with later on my iPhone. However, as the data is stored in your Facebook account, View Later will sync between RockMelt installations on different machines, and Vishria says mobile access could come in a future version.

The browser also gets a redesigned Twitter app. It now makes use of Twitter’s Real-Time API for near-instantaneous updates, and also has a redesigned UI which makes it much easier to access @ mentions and direct messages (DMs) via new tabs. The new interface looks very reminiscent of Tweetie/Twitter for Mac; Vishria describes the changes to the UI as making the app “more Twitter-y”

RockMelt’s integrated Facebook chat has also been improved, with a new unobtrusive chat bar along the bottom of the browser window, which allows users to hold multiple chat conversations simultaneously. Chat windows can be “torn off” from the chat bar and placed onto the desktop, making the browser into a much more capable chat client.

The browser has been updated under the hood, too: It’s now based on the same version of Chromium as Chrome 10, which should make for a snappier experience.

The new beta will start to roll out to users April 1.

• Virtual Worlds: Trends and Opportunities
• Why iPad 2 Will Lead Consumers Into the Post-PC Era

Last week, Internet Explorer 9 was released, and while Firefox 4 is due to be officially launched today, you can already download it from the Mozilla FTP site (UPDATED: it’s now launched, and you can download it from Mozilla). Luckily, so far, we haven’t seen any major issues with the new browsers, but there have been reports that some widely-used tools will need to be updated.

With that in mind, here is a short list of tests you’ll want to make when a new browser becomes available.

• Test your website(s). Make sure layout and interactive functions operate correctly, including content management systems, contact and feedback forms, styles and links.
• Test your collaboration tools. Web-based project management, screen sharing, conferencing and collaboration services should be updating themselves continuously, but you should check your intranet and any tools that have been built or are being hosted in-house.
• Test add-ons and extensions you and your colleagues are using. When you upgrade Firefox, it will check your add-ons and update or disable any that aren’t compatible. But you should also check the add-on developer’s website to see if there are beta versions available. And some add-ons may no longer be needed. After the controversy regarding hacking tool Firesheep a few months ago, I started using a Firefox add-on called Force-TLS that connected me to websites using HTTPS when possible. Firefox 4 has the appropriate technology built in, so Force-TLS is no longer needed.
• Test social media tools you are using. Especially check custom pages that you have created on sites like Facebook.

You’ll probably want to keep copies of old browser versions handy, since a lot of users don’t upgrade right away. This can be tricky, since some browsers, such as IE, don’t allow you to install two different versions on the same machine; virtual machines and browser testing services can be handy.

How do you test new browsers?

The web development company that I manage maintains a series of machines so that we can check the sites we design in a multitude of environments. But if such a setup isn’t feasible for you, you might want to try one of these options for cross-browser testing.

Browsershots

This web-based service is simple and offers a comprehensive set of browsers. If you need to know how your site will look in some very obscure browsers (including the text-based browser Lynx, and a few others that I’ve never heard of) on just about every operating system variant, Browsershots can help.

I asked Browsershots to display its default selection of 63 browsers. The app gives you an estimate of how long it will take for the screenshots to show, which wasn’t very accurate. Many of the shots appeared within a couple of minutes, and most were available within half an hour. The final three images never did appear; I gave up after three hours. The screen displays clickable thumbnails that expand to 1024 pixel wide PNG files that you can save locally.

Browsershots is free, but you can purchase “priority processing” to improve load time for $29.95 per month.

Spoon Browser Sandbox

This web-based service tries to go further than just providing screenshots by offering interactive views from several versions of Firefox, Chrome and Opera. Spoon says that “Microsoft has asked us to remove Internet Explorer”. Unfortunately, none of the browser emulations seem to work on Macs at all, in either Safari or Firefox. And despite Spoon’s claim that their service runs with “no installs,” Windows users must install a plugin for their system to work in Firefox, IE or Chrome.

Spoon’s browser sandbox available at no charge, and is just part of a larger library of apps that can be run virtually. It also offers self-hosted server options for enterprises.

Browserling

This service is also web-based, but provides an interactive view of browsers running in virtual machines. Some of the IE variants that the service supports actually seem to be rendered using IE Tester.

The service is in beta, and when I tried Browserling, it appeared to be having some technical problems, and their virtual machines were crashing a lot. But the concept is a good one, and I hope the company gets the kinks worked out.

Browserling is free during the beta period, and can be used for 90 seconds per session without registration; that’s not much time, since the service’s virtual machines take a while to boot. But you can also register at no charge, which will give you access to five-minute sessions.

Multi-Browser Viewer

Multi-Browser Viewer combines installed Windows software with a subscription. I haven’t tried this product, but it offers 22 browser versions, including IE6, IE7, IE8, Safari, Chrome, Opera and Firefox. It also offers five mobile browser simulators, including iPhone and BlackBerry, plus screenshot creation for over 60 Mac, Linux and Windows browsers.

It has several pricing plans, starting from an access plan good for 14 days at $29.95, or you can buy the software plus a one-year subscription for $139.95 (subsequent years are $99.95). A 14-day trial is also available.

Other Options

If you don’t need the comprehensive options above and are running Windows, you might want to try the IE Tab add-on for Firefox or Chrome, both of which simulate Internet Explorer in other browsers. You can also try the IE Tester software used by Browserling.

To make sure that your site looks good on mobile devices, check out the emulators for such popular mobile web browsers as:

• Mobile Safari (iOS, web-based)
• Android Browser (local install)
• Opera Mini (web-based)
• …and others

Of course, many other factors affect website usability, including:

• Operating system
• Screen size, resolution, and orientation
• Installed fonts
• Plugins such as Flash and JavaScript
• Processor speed
• Available memory

so the tests above should be supplemented with as much real-world testing as can be arranged.

The Mac version, meanwhile, is still in beta. I hope it makes full release soon, as its speed, coupled with Opera’s impressive feature set, could see it replacing Chrome as my primary work browser.

Have you been using Opera 10.5? Let us know what you think of the new browser below.

So what might the future hold for browsers? In my latest Long View over on our subscription research service, GigaOM Pro, “What Does the Future Hold for Browsers?“, with comments from Chris Wilson (Microsoft), Chris Blizzard (Mozilla) and Bruce Lawson (Opera), I look at where this new browser war might lead, and the battlefields that it will be fought on: innovative new technologies, browser performance, security and privacy, and the ability to browse from multiple, diverse devices.

How do you think browsers will change over the next five years?

Quick overview for those new to Firefox: Add-ons are little free tools that make your application experience better and easier. Add-ons don’t stop at browsers, either. Email applications like Thunderbird have them, too. They’re very easy to install. Just go to Firefox add-ons, browse, click “Add to Firefox” and click “Install” in the popup window. Once installed, you’ll need to restart Firefox to complete the process.

Here’s my list of current favorites (note: if you like this list, be sure to check out the WebWorkerDaily Firefox Add-ons Collection):

Adblock Plus — No. More. Popup. Ads. Or auto-playing videos. You might also want to download a Filter Subscription. You can still create your own filters to block ads on specific sites.

Better Gmail 2. Two great feature additions for Gmail. Folders4Gmail lets you have labels in folder-like sub-folders. Attachment icons replace the useless paperclips with the icons of the app that the attachment uses. If it’s a Word document, it’ll show Word’s blue W icon. Better Gmail 2 has other good features, too.

Download Statusbar. Get rid of the download pop up box. Instead, downloads appear across the bottom of Firefox where they don’t intrude. When you’re ready to open one, just double-click the relevant filename in the status bar.

Firefox Environment Backup Extension (FEBE). Any kind of backup tool for an application is worth it because it restores data with little effort. This one backs up your add-ons and rebuilds them.

Long URL Please. Twitter increased the use of URL-shortening services. But some of us like to know where we’re going before we click. This add-on automatically expands shortened URLs. Even if you can’t see the full URL, you can mouse over the link to see the full link tooltip-style.

Print/Print Preview. Adds a print icon to the tool bar with a down arrow giving you the choices of Print, Print Preview or Page Setup. I limit printing to stay green. This add-on helps because it ensures I print only what I need and nothing more.

Read it Later. I’ve always saved articles to read later by opening them in a tab and keeping it there until I read it. No, it didn’t lead to having a bunch of open tabs. Because I don’t like many tabs, it compels me to read them soon so I can get rid of them. Read it Later took over the job. The add-on puts a checkmark in your browser. Click the checkmark to add the page to Read it Later, click it again to remove.

Web Developer. I’m not a web designer, but this toolbar has helped me out many times. You can disable Java, Javascript and colors, manage cookies, change up styles with CSS, adjust form options and much more.

Word Count Plus. Anyone who writes web content where word counts matter needs this. Simple tool where you highlight the text, click the icon and see the word count. Now it just needs an added feature to count characters for Twittering outside the box.

Xmarks. A bookmarks synchronizer that works between computers and across networks. I first used it back when it was Foxmarks, but encountered issues. Those issues are now gone, and the add-on comes with more features. It can synchronize passwords, give you information about a web page and create separate profiles. You can have a profile for each computer so you can pick and choose which bookmarks to display at each location.

I’m sure I’m still missing some of your favorite add-ons, but I limit how many I install because Firefox does become a memory hog. So here’s your chance to fill in the blanks.

What are your favorite/most frequently used Firefox add-ons?

I’ve been using the beta for some time now as my everyday browser. In my experience, the beta of 3.5 has been far more stable than 3.0, particularly when I have large numbers of web apps open, so I would recommend switching to 3.5 RC1 if you’re not using it already, even though it’s not the final version.

I ran the new RC1 through the Sunspider JavaScript benchmarks. It appears to be about 12 percent faster than beta 4, scoring a time of 2200 ms compared with beta 4′s 2500 ms, but as I didn’t run the tests in parallel you should take that with a large pinch of salt. While it’s not quite as snappy as Google Chrome (by far the quickest browser available, which scores 1500 ms, according to my benchmarks), this new version of Firefox is still a very fast browser. This improved performance, coupled with the ever-increasing bandwidth available to users, should give developers much more scope to create powerful web apps with desktop app-like capabilities — leading to many more useful web apps becoming available for web workers.

Have you switched to Firefox 3.5 yet?
