Firefox 7.0

Mozilla Firefox is a fast, full-featured Web browser. Firefox includes pop-up blocking, tab-browsing, integrated Google search, simplified privacy controls, a streamlined browser window that shows you more of the page than any other browser and a number of additional features that work with you to help you get the most out of your time online.

The Web is all about innovation, and Firefox sets the pace with dozens of new features to deliver a faster, more secure and customizable Web browsing experience for all.

User Experience. The enhancements to Firefox provide the best possible browsing experience on the Web. The new Firefox smart location bar, affectionately known as the "Awesome Bar," learns as people use it, adapting to user preferences and offering better fitting matches over time.

Performance. Firefox is built on top of the powerful new Gecko platform, resulting in a safer, easier to use and more personal product.

Security. Firefox raises the bar for security. The new malware and phishing protection helps protect from viruses, worms, trojans and spyware to keep people safe on the Web.

Customization. Everyone uses the Web differently, and Firefox lets users customize their browser with more than 5,000 add-ons.

A partial changelog is as follows:

Drastically improved memory use
Added a new rendering backend to speed up Canvas operations on Windows systems
Bookmark and password changes now sync almost instantly when using Firefox Sync
Added support for text-overflow: ellipsis
Added support for the Web Timing specification
Added an opt-in system for users to send performance data back to Mozilla to improve future versions of Firefox. This can be enabled by installing an add-on
Fixed several stability issues

The Firefox website has yet to be updated, but we expect this will happen within the next 24 hours.

Unlike what Chrome trys to make you think, higher version numbers don't mean a browser is better.

I like Firefox better than Chrome. Has Chrome even yet added the print preview feature that every other browser had on version 1.0?

Can confirm auto update. (Did just now).
But I can't see any improvement in memory usage.... about 150,000K with only one tab open (and no addons). Firefox on win Home Premium 64bit.

between Firefox, Chrome and IE, it's IE that uses the least amount of memory for me.
87,636k for IE, 117,252k for Firefox and Chrome a whopping 202,556k.
All using the same amount of tabs and same webpages

If I'm not mistaken significant parts of IE are already loaded by the OS.

IE is aimed at the lowest denominator - the slowest PCs out there with low amounts of RAM.
Chrome and Firefox are not so much aimed at low-end PCs.

I can play The Witcher with higher FPS rate than I can scroll in Firefox 9a.

High End PCs: Firefox
Medium End PCs: Chrome
Low End PCs: Opera

Is there a way to go BACK and FORWARD by swiping 2 fingers on a touchpad just like in Safari in MAC OS Lion ? I cannot live without that feature anymore.

No autoupdate, but i downloaded / installed it manually and i am noticing a quicker load time for the browser. This may be a placebo effect though.

After a long time waiting,I still experience Memory leaks in the 6 versions, I wanna ask is this problem has been fixed finnaly in this 7 version?
I can't afford to keep this bad feeling again.
If there still exist this problem,I think I should switch to Avant browser whcih is integrated Gecko engine in their 2012 versios.You know firefox is not the only one I can choose. Chorme is also good in my opinion.

Firefox feel a lot faster to me, now. Do you agree?

I know they focused on Memory usage, but... it really feels like it scrolls and switches tabs a lot faster. (I have 4 tab groups and about 30 tabs, and Firefox 6 felt a bit sluggish even on a fresh start. Firefox 7 feels zippy)

It is supposed to feel lot faster With Azure and Memshrinks , it will be faster (with tab groups at startup as well) , and efficient

It does seem to be faster on my end now as well, but not sure if it is just a placebo effect.

At most, I have about 10 tabs open so can't really comment on that part of the performance, but do have it loaded down with add-ons for my web building and even with those, it does seem to be faster than 6.

How much of what I finally got to work in version 6, after a huge struggle from version 5, is going to work in version 7? I'm really getting tired of having to "fix" what Mozilla seems intent on breaking with their new version.

That depends on what things broke? I just read that Fx7 has 99% addon compatibility with 6, for addons on their addon hosting service.

Mozilla Firefox is a fast, full-featured Web browser...
...a streamlined browser window that shows you more of the page than any other browser...

last time I checked, Firefox was dragging behind IE9, Opera 11 and Chrome (and possibly Safari, I never use it) in terms of performance, and also having still most bloated UI while IE9 actually showing more of the page than any other browser.

If you configure it correctly, Firefox indeed shows much more pixel than listed browsers beating IE... Just right click the toolbar and customize it with "Use Small Icons" option.

Major version numbers for bugfixing is ludicrous.

Get me back to the old days when new functionality constituted a new Major version increase.

Well like i say the RAM use reduction alone is 'major release' material if you ask me. but other than that it's probably not to much overall even though i do believe there is some speed increase vs previous versions of Firefox.

This new release cycle is retarded. It's nice to have one version out with that is stable versus constant updates which is breaking Firefox (on multiple machines at home). Besides the addons are also annoying as there are version incompatibility (though can be fixed). Just a freaking pain for IT.

I don't believe the speed/memory improvements. They made that claim a few versions ago, and it really made no difference. It's still a slow browser compared to Chrome, and still uses a crap ton of memory. I really don't care much about RAM as I have at least 4GB on my systems, if not 8GB.

How about trying out Firefox 7 final and see the results for yourself instead of dismissing the results. chrome still uses more memory than FF, but for chrome it recycle's the memory better once the tab is close something Firefox hasn't done yet or will be soon.

Solid Knight said,
How is it that everything is always so much more efficient yet the browser handles almost exactly as it did in the last release?

in a article a read a while ago... it was saying Firefox 8 was about on par with Chrome speed (but Chrome i am sure has had at least a couple versions since then so i am not sure how it compares to Chrome's latest release)

but basically (from a article i read)...

Firefox 7 is about 10percent faster than Firefox 5
Firefox 8 is about 20percent faster than Firefox 5 (or about on par with Chrome (but like i said that was the Chrome i am sure has had a version or two out since then so i am not sure how it is now)

but like i say it's the RAM use where there is a CLEAR difference vs Firefox 4-6. which is more of a big deal with those of us with 2GB of ram or less. i suspect if you got 4GB+ it probably won't matter all that much.

When does 8 move to beta?

i am not sure but i would assume soon because i would imagine not much longer from now the Aurora channel will be serving Firefox 9 instead of it's current Firefox 8. i am guessing probably within a week or so the Aurora channel will change over to Firefox 9.

Just tested the memory usage. I have about 40 tabs open.

I shutted down FF 6.0.2 then started it again to see memory usage after fresh start. I did this 2 times in a row and got around 570K both time with plugin-container 122K.

I installed version 7 and it now reads 490K and 145K respectively.

Do the same if you haven't upgraded yet and share your results.

eblkheart said,
While it does run faster my question is, did they fix the memory leaks?

of course. the 50percent memory reduction is not BS. it's real.

RAM use in most cases typically floats around 200-300MB (sometimes goes over 300MB with intensive websites) with many tabs open after the browser has been running a while with opening and closing of tabs for hours.

where as previous versions of Firefox (i.e. Firefox4-6) burned up more and more RAM the longer the browser was running with the random opening/closing of tabs.

and to further add to my post... the RAM reduction is more of a real world performance booster than the slight gains in other areas especially for those of us with 2GB of RAM or less.

eblkheart said,

I'm not going to call the memory issue "fixed" but it certainly is SUBSTANTIALLY better than it was before. Firefox 3-6 would gobble up near a gigabyte of memory after a few days of moderately heavy use and then would slow to a crawl so I'd have to restart it. Firefox 7 (which I've been using in beta for a few weeks) seems to top out around 450 MB for me. I haven't been able to get it to climb much higher than that and stay there. (Still, I don't think Firefox has any business using 450 MB with only four tabs open.)

Aaron, it depends *entirely* on what is on those tabs, not the quantity of them. For example, four Google homepages versus four youtube/facebook tabs will use substantially different amounts of RAM (and also depends on previous usage of the browser, like if it's caching stuff from earlier in the session).

Essentially, 450MB for four tabs could totally be reasonable, and could happen in any browser (web pages are complex!). Anyway, yeah - it is lower than it used to be.

I agree. Facebook/Twitter seems to tax RAM more.

but on most websites you should not be @ 450MB for 4 tabs as i can typically float around 10tabs and RAM use typically is in neighborhood of 200-300MB.

Which is pretty damn good. If anyone runs chrome here you'll notice the browser can eat up over a gig of ram with around 15 tabs.

Might be real for you... for me however on a brand new machine.... not so much. It's performing the same as the previous version, with the same amount of memory usage. I only run three small add-ons and one tab currently.

Yeah, Chrome's memory is not that good at all. Just misleading... Being in separate processes for each tab may make it look better, but it's a hog too.

i would look into the addons being a possible issue as i got some addons myself but not alot. in fact, pretty much the only addons i got are... Download Helper/Download Statusbar/FireGestures/NoScript.

OR (better yet)... try clean installing Firefox. i.e. uninstall Firefox and manually remove the profile folder, then reinstall Firefox from scratch then everything will be completely defaults and clean and see what happens then.

because it sounds like something is up on your system as i am not the only person who claims those numbers that i did as i have seen many on Neowin say similar figures as me with RAM use.

This is getting annoying. Why do they have to do this like evry month? I hate having to update firefox on my work network every 2 months.

No one is forcing you to update.

Um, a 6-8 week cycle on security updates has been in place for as long as Firefox has been around, this is nothing new, and not specific to Firefox either. (I imagine security updates would be a higher priority than feature updates for deploying on your work network?) They've just changed the release strategy so that features that are ready make it to the front more quickly.

testman said,

Yes they do as Firefox stops supporting previous versions with security updates.

One think I like about chrome is it silently updates so you rarely notice it at all (unless they actually change something you visible notice), in addition to being able to install add-ons without having to restart the browser. Google seems to think of the user experience more then Mozilla, however, I think Mozilla is catching up.

I use a combination of Firefox and Chrome for my browsing and though I like how Chrome handles updates, if they don't tell you there's an update you would never know... My biggest gripe with Firefox is the breaking of addons. This was supposed to be happening less an less, but it seems to happen just as much as it used to...

From what I read, Mozilla will be doing auto-updating by the end of the year ala Chrome.

ThePitt said,

compared to what?

Let's just say I don't have to close my browser anymore to free up ram. I am constantly below 300 mb with many tabs open.

ThePitt said,

Exactly. My previous version was running the same memory usage as I am now with 7.0 - way too much, and I don't even have but three add-ons, with only one tab.

Compared to certain situations previously, hence the 'up to'. Don't expect an actual 50% decrease, but that is the potential of the various fixes.

They've almost caught up to the version numbers of IE and Chrome, haha. At this pace, they will be there in about 2-3 months.

3 Versions away from IE10.
About 9 versions away from Chrome 16.

Doesn't make sense to compare beta/alpha releases to a mainstream release.

2 away from IE9.
7 away from Chrome 14.

Moral of the story is that they are cranking out build numbers at a strangely fast pace.

which will be in Aurora channel soon once Firefox 8 goes beta which i am guessing will be in about a week or so.

MillionVoltss said,
Why not.

I'll tell you why not: I refuse to use Firefox until they reach version 56. By my calculations this should be in around 8 months time. Then and only then will I switch to Firefox. Currently using Chrome version 1,702 and it's running great.
