User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:14.0) Gecko/20100101 Firefox/14.0
Build ID: 20120605113340
Steps to reproduce:
Install Vertical Tabs extension
Install Stylish or User Style Manager extension
apply following css:
@namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul);
/*removes tab borders*/
.tabbrowser-tabs
.tabbrowser-tab:not([selected="true"]),
.tabbrowser-tabs
.tabbrowser-tab[selected="true"] {
-moz-border-top-colors: transparent transparent !important;
-moz-border-bottom-colors: transparent transparent !important;
}
Actual results:
Firefox 15.0a2 and 16.0
The css works as expected but the tab bar becomes much less responsive. Hover states take longer to catch up to the mouse. Closing and opening a new tab seems to take three or four times as long. __This behavior does not exist in 14.0__
Expected results:
No change in tab bar performance.
I'll confirm a huge negative change in behavior between /SeaMonkey/ 2.11a (aka FF 14) & 2.12a (aka FF 15, current Aurora) with the following userChrome.css :
@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");
/* Change color of active tab */
tab{
-moz-appearance: none !important;
}
tab[selected="true"] {
background-color: rgb(0,255,0) !important;
color: black !important;
}
This caused a huge (lets say 3-second) delay when switching windows, in addition to prolonged & irregular load from Session Restore.
Now I do have a few windows/tabs (690 tabs across 60 groups in 60 windows), so maybe it is more apparent for me then it might be for others.
(This was not particularly apparent in FF 15. In SeaMonkey, the entire tab is colored, green in the case here, where in FF there only appeared a very slight green bar a the top of the tab.)
I'll note that I NOT seeing this everywhere (every computer).
Where I noted this was with:
> Win7 x64, AMD (ATI) Radeon HD 6450, Intel i5-750, 12 GB RAM
The computer I am on now, with the same basic Profile runs flawlessly:
> XP x86, NVIDIA GeForce4 MX 440, Intel E4300, 2 GB RAM
Likewise, ColorfulTabs affected the Win7 computer & not my XP computer.
And again FF 15 seemed unaffected by ColorfulTabs.

So perhaps video (card/driver) related?
(I'll see if I can try an NVIDIA 6200 LE on my Win7 this evening.)
Perhaps my issue is different from yamiravko's?

Night & day.
No problems with the NVIDIA, much problems with the ATI/AMD.

Suggestions (other then switching cards again, which I have switched back to the ATI ;-) ).

Bug 765290 - Direct2D acceleration blits/copies whole window on every draw
I may have not been too clear.
I put my original ATI Video card back in, set the pref; gfx.direct2d.disabled;true & now my Win7 computer with the ATI Video card is working just fine.

I can also confirm that disabling direct2d fixes this problem. Thanks therube!

Another test:
Install Tree Style Tab (this extension applies its own css to the tabbar). With direct2d enabled, Nightly is very slow in seemingly all tab operations. Disable direct2d and things work great.

I no longer have the machine I filed this bug with. Nevertheless, it did seem to be an issue with direct2d and older video cards.
