I have also tried re installing it to no success. I first attributed the issue to fire fox sync plugin. It seem to coincide with the crashing and hanging. So I uninstalled the plugin and its getting worse.

I don't know if this is the proper bug report, but since I started updating Lucid to Maverick (so before the upgrade was even complete) Firefox has started freezing for no apparent reason.

I usually have a lot (a lot… ~90) tabs open, and also have a bunch of extensions, but some of these are designed to make the amount of tab usable (such as Bar Tab which unloads tabs, so right now even with about 100 tabs memory consumption is only 150 MB).

After some time, a few minutes or tens of minutes, Firefox hangs completely, not answering anything.
CPU usage goes up to a little under 100% and stays there for as long as I don't kill the process.

I tried starting in safe mode but the same thing happened, which would lead me to think that the add-ons are not to blame.

Maybe one of my tabs is ? But as most of them aren't even loaded, it seems a little weird.

And the freeze doesn't seem to be triggered by anything in particular, it usually happens when I'm just srcolling down a page, or writing in a text box such as this one.

I've tried starting Firefox from the terminal for extra info but it doesn't output anything significant unfortunetaly.

Next step might be to install the Mozilla build of Firefox from the Ubuntuzilla project to see if the problem appears in that version of Firefox.

Otherwise I'd be happy to test out whatever is needed to solve this.

Firefox is one of my main tools, I don't really want to have to stop using it.

More details…

I started Firefox with "Firefox -console".
This got me a few lines of:
###!!! [Child][RPCChannel] Error: Channel error: cannot send/recv

and one instance of this one:
###!!! [RPCChannel][Child][RPCChannel.cpp:159] Assertion (!ProcessingSyncMessage()) failed. violation of sync handler invariant (triggered by rpc)
RPCChannel 'backtrace':

(yes, that's where it ends)

Also, when FF hangs and I'm watching a Youtube (Flash) video, the Flash player stays responsive (for a while) when the rest of FF has already moved to “I'm completely stuck” land.
Even another Flash video player lower on the page kept giving cues it was working (shimmer effect on the “play” arrow when I hovered over it) and the mouse cursor kept on changing from the regular pointer to the hand one gets when hovering over links.

This is Firefox 3.6.12 on Ubuntu 10.10, as the original bug reporter.

Until now I have had no useful information or input concerning this problem. I know there is at least another person who reported the same problem--with you that makes 3. I upgraded from 10.04 to 10.10 3 days ago and have had nothing but problems since then. I don't have more than 1 or 2 open tabs on Firefox, so that is also not a cause of the problem. It is especially bad on Googlemail when I am writing an email--sooner or later everything freezes. If I wait long enough it speeds up again. . .until clock somewhere and then it freezes again. Sometimes the only way I can stop it is to force Firefox to quit. I also have problems with VLC that may be related to the upgrade. All my media players were problematic the first day or two--jerky would best describe it. But today VLC didn't work--I had good sound but no picture! I get the same problem with hanging and/or freezing with Google Chrom, so it doesn't appear to be just a problem with Firefox. I even
sometimes get the problem when working on my desktop without any browser loaded.

I would appreciate more input if you have any new developments--the Launchpad helpers don't seem to be reacting this time.

Ciao,
