Meet Firefox 4.0.1

[Inklin]

Guys, I do not know whether or not these mockups have been posted already but they are indeed DROOLWORTHY!

tabcandy mockups on mac

:wub: I don't often get to use OS X but THAT looks sexy!

I usually have 15-20 tabs open all the time... I like the fact that when I shutdown Firefox and restart, all tabs are back.

Firefox 3.x can do this. Go to TOOLS-OPTIONS-GENERAL-STARTUP-"choose my windows and tabs from last time"

I have about 40 tabs opened each time i start firefox, unfortuntely firefox 4 is using around 1000mb of ram, firefox 3.6.8 uses about 530mb so i'm sticking with 3.6.8, lets hope they reduce it by the time firefox 4 final is out.

Beta 3 code freeze by Monday, I think.

Nothing much new though.

Firefox 4.0a uses less memory than 3.x for me O.o ~300MB average with about 20 - 30 tabs opened, running the latest nightly build. there has to be some addon causing some serious memory leak for you.

[radwimp]

For me, firefox.exe only uses up around 300 or 400mb with 25-30 tabs, but the plugincontainer is a real memory leak. Viewing flash videos or podcasts that on 3.6 would only be 60-90mb, shoot up to 400mb+ on the v4 betas. Hopefully that issue will be resolved.

[The_Decryptor Veteran]

Yeah, Flash can eat a whole lot of memory.

Look forward to better D2D performance in Beta 3 - two performance fixes have been pushed to main.

Will test D2D today probably.

[NightSt@lk3r]

The nightly build for the 30th doesn't work at all for me, it just does not open, firefox.exe is listed in taskmanager using 50% of my cpu and about 31mb and it never progresses from there, went back to the build from the 29th and its fine again.

[Udedenkz]

Tested D2D,

It still seems a rather jittery... but much better though.

Works For Me. Have you tried a new profile?

I wonder how much the Compositor/off the main thread compositing would help with jitter/performance.

I think it still tries to paint as fast as possible, meaning it might be drawing at 200fps on certain pages (even though it can only ever display 60fps or so, meaning frames get lost/torn/etc.)

Edit: Retained layers greatly reduces the cost of rendering a webpage to the screen, which could result in an even greater framerate if the drawing code isn't smart (which has an even worse end result)

[SkyDX]

Any word maybe on a compatible Download Statusbar version?^^

Edit: Found a Download sidebar, good enough replacement for now so I gonna test drive the newest nightly as my main browser for a day. Something I noticed instantly, waaay higher memory usage. I have 42 Tabs open and 3.6 kept it at 400-500mb while Minefield comes out with stable 699mb.

The jitter, when scrolling, is due to Direct Write being turned on. Still.

It is also easily noticeable with things like the IE9 tests, it actively skips frames.

I guess it is time to fill out my first bug -> 583431

Two problems:

1. How come some add on downloads give me a connection failure error? Is it because they aren't compatible with beta 2? I have the compatibility reporter add on installed.

2. What happened to the tab width setting in about:config? Is there any way to get back the option to change your tab width? They're too wide.

To 2:

Tab Width is now controlled per Stylish, make a new style containing:

.tabbrowser-tab {
  max-width: 100px !important;
  min-width: 100px !important;
}

and adjust the numbers to your needs^^

Download Statusbar was updated to work with Beta 1, but now it's broken again in Beta 2. Not sure whether it'll work if you force it to.

Yeah forcing made no difference, just nothing comes up when downloading. That download sidebar also only worked once :blink:

Just wondering is there a list somewhere on a site where it has a bunch of userstyles listed for Firefox 4?

Is there a userstyle atm that makes tabs kind of like Chrome's, where they are not transparent, for inactive tabs? The inactive tabs are a major problem for users who have dark backgrounds.

Thought these three links were informative:

https://bugzilla.mozilla.org/show_bug.cgi?id=583386

http://people.mozilla.com/~faaborg/files/20100718-firefoxButtonDetails/menuMigration-i1.png

Should be implemented by beta 4.

...and according to the bug report comments there isn't going to be any edit menu commands in the title bar next to the menu button.

I personally don't see why they need to be in the menu at all.

[Brandon H Supervisor]

i wonder how long till we see it in the nightlies?

Hmm do you know what page it is off hand? Closest thing I found was on page 8, but it made them exactly like the active tabs.
