Firefox 3.5 RC Lands, Final Version In June

It has been an age coming but with the first Firefox 3.5 Release Candidate launched today it looks like the massive overhaul is almost complete.

What's new the latest version?

  • Improved tools for controlling your private data, including a Private Browsing Mode.

  • Better performance and stability with the new TraceMonkey JavaScript engine

  • The ability to provide Location Aware Browsing using web standards for geolocation.

  • Support for native JSON, and web worker threads

  • Improvements to the Gecko layout engine, including speculative parsing for faster content rendering

  • Support for new web technologies such as: HTML5 and elements, downloadable fonts and other new CSS properties, JavaScript query selectors, HTML5 offline data storage for applications, and SVG transforms

  • Now available in 70 languages
Strangely Mozilla listed the same qualities for Firefox 3.5 beta 4 so we're into spit and polish time - unsurprising since it hopes to have 3.5 out before the end of the month. Other central aspects to Firefox 3.5 are the new Gecko 1.9 rendering platform which is more than twice the speed of Firefox 3.0.x and a private browsing mode.

I'm running the new version now and happily it seems to play nice with virtually all extensions that worked with previous betas. That said, the continued lack of Google Gears compatibility does cause a few sniffles.

Pointing out the obvious. It's less snappy that chrome and still has an ugly interface. Plus I'm not sure what it is (probably the interface) but it feels clunky to use after coming off Chrome. That said, private browsing that opens in the current window is something I like.

My only wish is for Firefox to open a bit more quickly when first used, but I hear that's coming in Firefox 4. Oh, and I wish you could open private browsing sessions in a new tab, instead of it opening a new window for you.

Nice to see someone else not just frothing with excitement about Firefox. All the new features may be great, but it's too damn slow to load and is clunky to use. The add-ons may be great, but for 98% of browing Chrome just works faster and more elegantly, hell even IE seems easier.

I think what they're doing with Firefox is amazing and certainly the future. But I think they've just been building it on stodgy foundations. It's like Vista a great idea, but too slow and poorly implemented. They need to Windows 7 it, give it a decent polish and make things clearer. Maybe FF4, for if not Chrome's going to catch up.

Not that I even understand the race, what difference does it make if I browse with FF, IE, Safari, etc? What's the business model for all this? Where do they make money? Search I understand, that's advertising, but not the browsers themselves.

I'll reserve judgement until 3.5 is officially released. But with the competition really upping their game, Mozilla can't afford to mess 3.5 up. Chrome could become the browser of choice for most tech-savvy people once add-on scene is up and running and if 3.5 disappoints people, I can see Firefox's market share dropping off as some people jump to alternatives.

I've avoided installing beta versions of 3.5, but is the bookmark system revamped or is it the same catastrophic mess that was implemented in v3.0? I find it amazing that the only browser that has a decent bookmark manager is the much maligned Internet Explorer!

chrome is faster than FF? since it first came out i havent seen anything special, i always found the page rendering slower then FF and IE and with no add-ons for me its pointless.

For me FF is fast and allows me to customise my web experience how I see fit (adblock plus is a must have, still shocks me when i visit certain websites without it), as for it opening slow, yea i agree but it is also loading close to 30 tabs so maybe thats my problem.

@Steve: the bookmarking is good in IE? not 7 though surely? I find it ridiculous, getting favorites on bar below the address is long winded, you cant drag and drop onto the bar either whereas FF is more intuitive, plus i love typing in the address bar and it finding my bookmarks or pages ive visited, just have to be careful theres nothing dodgy in the history or everyone sees you the dodgy site you were looking at in the middle of the night.. tsk tsk

Forgot to mention the lovely, shiny new icon for OS X too. That's always worth something :)
