If this is the wrong forum, could you move it to the right one?
I know there are several of these on the forums, and that firefox generally is not a race-winner, but this is different. After upgrading to 2.0.0.2, there is a noticeable slowdown. Regular sites are unaffected, but the program slows down massively when on gmail, or when loading large images. The problem is not the connection, because the pages load quickly enough, and, when moving from one tab to another with a large image, firefox slows to a crawl, making the browser almost unusable. This is especially pronounced when scaling images, but whether that is because of scaling itself, or just the size of the picture, I cannot really tell.
Top shows that the CPU usage goes up to 100%, but no excess memory gets used. Closing the tab with the large picture corrects the slowdown, and usage goes back to the normal 3-5%. I am assuming it has to do with image drawing, since it slows down only when there are large images (or with gmail). I am no programmer, so I am only guessing. I could not find this in the Flyspray, and the Mozilla bug thingy (with the hungry dinosaur) is too cumbersome to check this late at night. I found nothing identical to my problem in the first twenty search hits or so.
I haven't reverted anything just yet, I will try to revert to .1 tomorrow afternoon (after I get back from school) and see if the problem corrects itself.
Does anyone else have this problem?

Hi.
I can't confirm this but I suggest you to try to reconfirm your problem when using a completely new profile. So backup your firefox profile folder (move it temporarely) and start firefox again. Do you still experience the slow-down? Propbably it's an extensions fault...

Firefox in linux is crap.
The DHTML pages that I make break its stability (only in Linux). Unfortunately, Konqueror doesn't show well many pages, so i have to keep using the dinosaur.

I moved it, and Firefox gave the "already running" message, even after I restarted the whole computer.
I ABS'd it, with all optimizations I could do safely, and now it runs fine. It's not that the new one is slow, but that the last one was also one I optimized myself, and when it upgraded it used the repository package, with only the default optimizations. I would switch, but am quite attached to the extentions, so this will do for now.
Solved.

IT ISN"T JUST FIREFOX...
My experience has been that EVERY browser (those available for a quick pacman install at least) causes the processor to spike when loading a typical Web page... any typical Web page, with or without the Flash plugin. Opera as well as Firefox as well as Epiphany.
To be fair, I haven't tried to ABS any of the browsers.
I had read somewhere that this had to do with IPv6 being enabled - so I disabled it in rc.conf, and, in the case of Firefox, in that browser's config as well (Firefox has a configuration setting for IPv6). There wasn't any noticeable improvement in my case.
What I've resolved myself to believing is that it has something to do with Xorg and the fact that I'm running 3 monitors off two ATI Radeon cards using Xinerama. I've got nothing weird in my xorg.conf. I haven't tried testing with a different xorg.conf, but seeing as how I just thought of that I may just try using the default "hwd -x".
The WORST thing about this problem is trying to use browser applications (such as phpPgAdmin) via "http://localhost/...". Because the browser has maxed-out the processor, the localhost application has to fight to do its thing, and every subsequent page refresh takes a very, very long time.
Well, if anybody knows anything...

You can try these settings in about:config
network.dns.disableIPv6 = true
network.http.max-connections 48
network.http.max-connections-per-server 24
network.http.max-persistent-connections-per-proxy 12
network.http.max-persistent-connections-per-server 6
network.http.pipelining = true
network.http.pipelining.maxrequests 32Having said that though, I still find Firefox to be snappier under "that other OS". Using Javascript-rich sites like Google Docs can be a pain with this computer, which is not entirely ancient (if not very new either, an Athlon 2600+ XP). I really wish Konqueror would be better supported...
