Mozilla has just released the final version of Firefox 3.5. The JavaScript performance — critical for many web apps — is massively improved thanks to the new TraceMonkey engine, making 3.5 feel very fast indeed. In addition to improved performance and standards compliance, Firefox 3.5 features new privacy controls, location-aware browsing, and the ability to play video and audio content without using plugins. A quick video tour of the updated version is available here. Firefox 3.5 is a free download for Windows, Mac and Linux from Mozilla. (The story was originally posted on WebWorkerDaily which also has reviewed the release candidate for this new browser.)

  1. When looking at the update option through FF, it says all of my most oft-used plugins would be disabled if I upgrade. These include Web Developer, Firebug, ColorPicker, and others. Maybe I’ll wait.

  2. Nice. But have they fixed the memory issue which causes the flash plugin to stutter? Its not a problem with flash but with Firefox. I researched it.

    This issue caused me to use Firefox as a secondary browser, and switch to the excellent Safari 4.x browser. Now video watching is fun again, and my secondary browser has all the plugins which I rarely need to switch to unless i need to debug something.

      “Here we saw an experiment that tested the memory usage of Firefox 3.5 and Google Chrome 3.0, along with Safari 4.0 and Opera 10 (some pre-release versions). The memory watcher program that recorded and accumulated memory every three seconds over 19.2 minutes of intense browsing in four browsers at semi-random intervals reported figures that place Firefox 3.5 in the clear lead in memory usage. Firefox 3.5 showed the best memory efficiency in the average, maximum and final measurements.”

    this is bad advice for anyone who wants to keep their Norton Safe Web and Anti-Phishing toolbars working. these are currently incompatible with Firefox 3.5….

    1. Rich… good point. Sometimes we Mac guys don’t remember those points. Sorry about that and glad you brought it up.

    2. Unfortunately my Norton Safe Web (Norton Internet Security 2009) does not work with Firefox 3.5. I have already abandoned Google Chrome just because. What else can I do? The only option is keep my Internet Explorer…

      1. No: change your antivirus ! I got the same problem with NIS 29009. But I tried ff 3.5 on my second PC with Kaspersky and it worked absolutely perfect !

      2. … change to Opera.
        I run version 10.0.3beta, and its faster than Firefox.
        FF is ditched because its a spaghetti of core and “add-ons”. The problem with the “add-ons” is that they work differently, every one has their way of doing things that differs slightly. Simple things like “Save As” becomes a nightmare when you loose track of the “add-on” used that will then determine where the file was saved on my disk.
        Opera has “Widgets” that works within the Opera framework. It also has a complete email client, and industry customers that demands reliability and not just performance.
        … but then it is not invented in the USA.

  4. Meks- Firebug and ColorPicker have 3.5 versions (https://addons.mozilla.org/en-US/firefox/addon/1843 and https://addons.mozilla.org/en-US/firefox/addon/271, respectively). Not sure about Web Developer toolbar. I was a bit worried about upgrading for the same reason- for whatever reason, Firefox didn’t find the upgrades.

    1. I think most of the plugins will be up-to-date soon enough. I am sure you can run two instances of the browser on your computer – the old and the new one.

  5. Got it and love it. It does feel quicker loading more complex pages than before.

  7. slower to start-up the application – consistently (chrome is the fastest), after its loaded webpage browsing does seems faster.

  8. Need to update the post icon to the new Firefox logo ;-)
