On the downside, this means that my Firefox installation may end up being a total mess: running different versions of the same program is never a good idea, and even less in the case of Firefox which I use to work on a daily basis.<\/p>\n<p>If you can&#8217;t wait until the final version comes out, but at the same time don&#8217;t want to run any risks with your current Firefox version, use the <a href=\"http:\/\/portableapps.com\/news\/2008-04-02_-_firefox_portable_3_beta_5\">portable Firefox<\/a> instead. This special Firefox edition can be run from a USB device &#8211; or from your computer itself, without having to install a single thing. In this way you can take a sneak peek at the new exciting Firefox 3 features without compromising your previous installation and therefore your bookmarks, saved data, user profile and so on.<\/p>\n<p>Now that you&#8217;ve managed to test Firefox 3 without ruining the good ol&#8217; Firefox 2, what about extensions? Most of them may not be compatible with the latest beta yet so you&#8217;re probably wondering if there&#8217;s any way to make them work. And the answer is yes: it&#8217;s called <a href=\"https:\/\/addons.mozilla.org\/en-US\/firefox\/addon\/6543\">Nightly Tester Tool<\/a>, an extension that&#8217;s been especially developed to make your old extensions compatible with the <a href=\"http:\/\/www.mozilla.com\/en-US\/firefox\/all-beta.html\">latest Firefox 3 beta versions<\/a>. Of course, this is no magical cure for all extension incompatibility issues, but I must say it worked for me perfectly fine. Nightly Tester Tool also adds some useful tools for beta testers, such as a built-in screenshot app, direct access to the Profiles folder and a log file analyzer.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>While the final version of Firefox 3 will supposedly be launched in June (at least that&#8217;s the latest news from official sources), as an avid software tester I can&#8217;t keep myself from testing every single beta that comes out before the great day arrives.
