Mozilla releases Firefox 4 RC Download it here: Firefox 4 RC
Mozilla has released the first Firefox 4 RC this week, meaning the final release of the browser is likely coming within weeks.

All beta testers have been automatically upgraded to the RC, which has over 8000 bug fixes since the first beta last year.

The browser features a minimalist interface, much improved JavaScript performance, increased HTML5 support (including WebM) and "a revamped plug-in architecture called JetPack," says PCM.

Firefox 4 adds the ability to create tab groups (dubbed Panorama), and adds tab pinning, as well. Frequently used sites, like Gmail and Twitter can be created into App Tabs, which means they will pin, and glow when updated (new tweets, new emails).

As with past versions, you can sync all settings, passwords, bookmarks and open tabs to mobile devices via secured 26-character key.

70 percent of add-ons are compatible with the RC.

Finally, the browser adds "do not track" to the "advanced" settings screen. By checking the option, you are telling sites that you do not want to be tracked for specialized advertising.

Yay!

I hate release candidates! Just another term for "Final Beta". Just ditch the RC and simply RELEASE.

Though I am excited about the official release of FF4 as well as IE9. Not touching them until the official release though.

Not touching Firefox for a very long time. They won't acknowledge their own organisational and technical (memory and start-up time) problems. Firefox has nice things, and I might still use it here and there besides for testing purposes (as a developer) but it has gone crappy where it needs to be good and Chrome wins in those areas while lacking in the ability for extensions to do as much as they do in Firefox.

If Chrome implements Firefox's extension system (XPCOM), Firefox will be dead so fast!

Yeah............No.

Though I can see where people want to use Chrome because they think Google is the end all be all of everything and rulers of the world......I can say with absolute certainty that Chrome is garbage. It's level of incompatibility makes it garbage. It's just another browser with few features and frankly, NO ONE can (practically speaking) tell the speed difference from one browser to another. If those milliseconds bother people, well then, they're just impatient morons.

Coming from someone who definitely only used Chrome 1.0 and then left it for dead. Garbage? Hardly. Tell me the last version you used and what "incompatibility" issues you currently have, please, would love to hear it.

Current version..............not compatible with any Citrix ICA client for schools, work, etc without major finagling.

You asked for an example, you got one.
