Mozilla Firefox 3.5 released

Advertisement (Why?)
Mozilla has officially released Firefox 3.5 today as predicted earlier this week.

Firefox 3.5 is the first major revision since 3.0 was released about a year ago. The new version sports a faster rendering engine, stability enhancements and a new javascript engine. It will also include support for the most widely-used elements of HTML 5 that allows for offline data access, enhanced web graphics and multimedia playback without plug-ins. The Firefox logo has also had a small revision as well.

Mozilla has been showing different 3.5 features within a 35 day period, and has also shown the new tools developers can take advantage of in the new version.

The new version was originally going to be 3.1, but was renamed to 3.5 later to reflect a greater scope of changes than what had originally been planned.

What's new in 3.5?

According to Mozilla's release notes:
  • 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, 'video' and 'audio' elements, downloadable fonts and other new CSS properties, javascript query selectors, HTML5 offline data storage for applications, and SVG transforms.

That is for the USA version. Obviously if you have a different language or
OS, you'll want to back down to /releases/3.5/ and pick an OS or language to suit you. I snagged it around 6am CDT. It always shows up on the FTP site about 3/4 of a day early.

on my PC which is pretty high end chrome does load things faster, but i find startup the same and the features/extensions make firefox worth it for me

i still use chrome though for certain things

master2k27 said,

No. Neither in web browsing, nor start-up. But it's much more competitive at least. Firefox 3.0 was sluggish. It'll still likely be beat by Safari and Chrome, but it's on par with Opera 10 and up to twice as fast as Firefox 3.

WOW it's faster, although I use a lot of software for development with FF, just waiting on updates which should not be long, some of the major one have already upgraded their software it's just a small amout of people whom have not updated their software yet. Symantec need to update their plug-in for 3.5 as it's incompatible.

With refernece to Norton IPS and Norton Toolbar I just found an article from Symantec that IPS and Toolbar are still in development although it does not state a release date.

Big disagree here. IE has it and it is very useful and you can quickly open a new tab.
#16.3 Dead_Monkey on 30 Jun 2009 - 16:51
You could already quickly open a new tab by double-clicking the empty part of the tab bar. The button is superfluous (much like the maximize button on windows).

Not when you have so many tabs open that the whole bar is full. Its annoying at that point because there's no where to click to open a new tab. So you have to ctrl+t it.

GreyWolfSC said,

Doesn't mean it's not possible. There are (or certainly used to be) lots of hacks you could do by adding new entries to about:config. One that springs to mind is config.trim_on_minimize=true which used to be a godsend for FF1/Windows when it was leaking a lot of memory.

Even if there's not a config directive, you should be able to make it invisible by adding something to userChrome.css -- they've still got that, right? -- keep an eye on mozillazine.org forums, this is bound to be covered before long.
#16.9 Firebird56 on 30 Jun 2009 - 20:08
If you go here and download the beta version of Tab Mix Plus. You will find that you can switch off the button, on the tab bar page under Display.

Hope this helps, and yes it works for me.

Exactly as I'm typing now.. 6 tabs open, no space to double click.
#16.13 Joshie on 01 Jul 2009 - 00:58
If anything, it's just as compelling an argument to say that getting rid of the new-tab button would just leave you with empty, wasted space. By taking advantage of otherwise empty real estate, and giving the user a single-click solution, they're actually being MORE efficient.

Minimalism is about intelligently using the space you have, not locking space out and saying NO NOT YOURS.
#16.14 soawesomedude on 01 Jul 2009 - 17:38
In userChrome.css: ( http://kb.mozillazine.org/UserChrome.css )

.tabs-newtab-button {
display: none !important;
}

Some other nice ones:

.tabs-alltabs-button,
#star-button,
#feed-button {
display: none !important;
}
#go-button { /* about:config's hideGoButton is not enough, wtf! */
list-style-image: none !important;

ran a little test script on ff3.5, faster than ff3.0 on both js and DOM render.
now beats safari/chrome on js speed to become the fastest, but is still behind Opera 10 on rendering speed.

Memory footprint after my stress test is larger than ff3.0's....

Good update. While it won't pry me off of IE8 and the Opera 10 beta, its good to see FF3 updated and sped up a bit. Since I mainly just use it for web design testing, its nice to not have it running slower than dirt like FF3 did on my setup. Good job, Mozilla!

How much ram do you have? And whats wrong with a program using your memory when its not used by anything else?

People that claim that they don't use X, Y, Z program/game because it consumes too much memory irk me. What the point of having 4 gigs or ram and only using 1 of it?
#33.2 E.Fahd on 30 Jun 2009 - 19:37
I have 2 gigs and I use a lot of programs that are memory consuming, so I can't afford 300 or 400 megs just for the browser.
#33.3 Red Dragon on 30 Jun 2009 - 20:09

Just to verify, I run the browser all day (I updated to 3.5 about 6-7 hours ago) for the whole time I had a minimum of 3 tabs open and right now FF is used 103 mbs which I find perfectly reasonable.

Opera 10 beta 1 show the websites exactly like firefox I don't see any difference, and is loading a lot much faster compared to firefox 3.5 release (and don't forget that opera 10 is still beta 1 )

I have used firefox for years and I must say that can't compete with Opera 10 is not even the same category, firefox must work a lot to get in competition with opera
