Firefox 4: fast, powerful, and empowering

[Rahim]

Today, I presented an early product plan for Firefox 4 to the Mozilla community (live, over the web!) to share our vision for the next version of Firefox, and what projects are underway to realize it. Then I invited everyone to get involved by joining our engineering or product development efforts.
The primary goals for Firefox 4 will be making a browser:

• Fast: making Firefox super-duper fast
• Powerful: enabling new open, standard Web technologies (HTML5 and beyond!),
• Empowering: putting users in full control of their browser, data, and Web experience.

Usually software producers don’t present these sorts of plans in public until they’re finalized, but Mozilla is a little different. We work in the open, socializing our plans early and often to gather feedback and build excitement in our worldwide community. Not everyone could attend the presentation today, though, so I’m sharing the slides and video here as well.
That said: please understand that these plans are fluid and are likely to change. As with past releases, we use dates to set targets for milestones, and then we work together to track to those targets. We always judge each milestone release against our basic criteria of quality, performance, and usability, and we only ship when it’s ready.
If you have Firefox or a modern web browser that supports fully open HTML video, you can watch the presentation.

Yes...well said..though these days 2-4gb ram is common..but still mozilla has to fix memory leak

[NIGHTMARE]

most of the time i open 10-15 tab then RAM uses is between 2.35-2.85

[celldweller1591]

a good news ^^ of FF4. I think the memory leak problem will be fixed in a short while.

I also use firefox with 10-15 tabs but mine goes upto 3.10-3.20 ram in windows 7 but ubuntu uses lower ram even with 15+ tabs .

[sujoyp]

3.10 by u mean more then 3gb??? better use opera..it consumes less memory

I use firefox too and love it...I want a similar feature like opera turbo boost....it degrades the quality but improves the speed drastically

[DigitalDude]

the mem usage in the taskmanager reads as 1,82,156K i.e. 182MB for me with around 10 tabs open in FF.

If you guys are indicating 2~3 GBs of RAM using those numbers here, then you're out of your freaking mind.

well said...lol mine is just less than 200 mb for 30-40tabs

[sujoyp]

in my PC after opening 5 tabs RAM usage becomes 450-55mb

[Stuge]

Only reason I see these days for using FF is bcoz of plugins it has got .otherwise I prefer to use chrome .

[celldweller1591]

3.10 i meant 310 mbs of memory

[sujoyp]

actually I think it depends purely on websites which u r viewing...number of plugins and addons used simultaniously

[celldweller1591]

i basically browse wiki, ubuntu forums, digit forum, linoob forum, seven forums, twitter, facebook and some tech news blogs and firefox is loaded with addons

[ico]

11 tabs + IRC tab.

[sujoyp]

ok mine too with 10 tabs is taking 170mb...but it really depend on websites

[Rahim]

memory leak has hijacked this thread

The thing on which Mozilla needs to focus on is the performance of Extensions with Firefox.

Firefox's memory problems were fixed long back. It has just got a bad name for being "heavy on memory." It actually uses less memory than Opera and Chrome. (I've observed this since 3.6) That doesn't mean it is faster though.

This (wo)man speaks the truth. My main browser is Opera, but I have observed that Firefox is the browser with the lowest memory footprint.

Chrome, on the other hand, uses a lot of memory. Just because it's fast in rendering websites, people get the illusion that it is lightweight, when in fact, it is far from it.

[gopi_vbboy]

Hail Firefox!!!!

[Krow]

I want:

Faster startup
Faster rendering
FF should be closer to the likes of Chrome and Opera.

[NIGHTMARE]

see 19 tab and uses 2.57

[DigitalDude]

5 Firefox windows with 10 tabs each = 50 tabs with all kinds of sites loaded completely.

mem usage by firefox.exe ~ 446MB (see the task manager first process in the pic below)
my total sys mem usage ~ 1.41GB (47% of my 3GB sys memory)




@nightmare
show your processes tab with firefox.exe visible.

Firefox starts up INSTANTLY on my computer. Chrome and Opera take a little longer time. Only a fraction.

[Gauravs90]

open taskmanager process tab
view -> select column and check VM Size

Then it also shows virtual pagefile usage for firefox

here is the screen shot

[DigitalDude]

btw you are using 64bit win 7. I dunno about that whether that's why you have so much memory usage ?

any 64bit guys can comment on the same ? or is it just some issue with nightmare's pc alone ?

bachao muhje

[rjazz]

url for FF4? plz!

[hellknight]

Lets get away from memory leak for a while, Opera 10.5x is also suffering from memory leaks..

@ a_rahim.. any idea if the new Firefox will sport a new Javascript engine.. Coz this is one area where Firefox is seriously lagging behind the other browsers... I read sometime ago in Ars Technica that Firefox is going to take the Javascript engine from Webkit.. is it true??
