Mozilla Firefox 5 The Great Internet Browser ReviewAs a result, Firefox 5 arrived in record time. However, how good is Firefox 5? At first glance, Firefox 5 looks and feels identical to Firefox 4. Yep, the biggest user-perceivable change in Firefox 5 is a minor interface tweak.
Other than this, Firefox 5 adds supports for CSS animations, improves canvas, JavaScript, memory, and networking performance, and improves standards support for HTML5, XHR, MathML, SMIL, and canvas. As mentioned earlier, it also fixes some extremely critical security issues. To be honest, Firefox 5 doesn’t merit being called anything other than Firefox 4.02. Mozilla has announced that it doesn’t plan on maintaining the Firefox 4.x trunk, so users have no choice but to jump aboard Firefox 5 in order to stay secure. Firefox 5 is a great browser, because Firefox was already a great browser.
Do version numbers matter? With Google's Chrome well into double figures, we'll probably have Chrome 99 by Christmas - and that means Firefox's more sober numbering system runs the risk of making Mozilla's browser look old.
Hence Firefox 5, which doesn't actually have very many new things compared to Firefox 4 and which will shortly be followed by Firefox 6.
Firefox 6 release date is September 2011.
The big list of what's new in Firefox 5
There's a new button that tells websites not to track you, and Firefox now supports CSS animations.
WebGL security has been tightened up, there's been some tweaking to improve JavaScript performance and memory usage, life's much easier for extension developers and there's improved HTML5 standards support.
FIrefox 5 user interface
Annoyingly, the only way to save your Tab Groups is by shutting down Firefox; unless you've disabled Firefox's session restore, your groups will be intact when you open the browser again. It'd be much better if you could save groups as you do bookmarks: while you can save a tab group using Firefox's Bookmarks > Bookmark All Tabs option, which only saves the currently selected group. A Save Tab Groups option would be handy here.
As before, Firefox has an address bar and a search box, although if you don't type a URL the address bar takes you to a web search anyway.
If a firm decides not to respect Do Not Track requests, there's not much you can do about it.
Firefox 5 performance
While Firefox isn't a true multi-process browser like Chrome, it does run plug-ins in a separate process, enabling you to kill them if they misbehave without taking all your other tabs down too.
Firefox 5 extensions
Firefox remains the best browser for tinkerers, control freaks and anybody who wants their browser to be more than a browser.
