There is a firefox.exe running in Task manager but the browser won't start

Same problem. Win XP May be conflict with plugin, for example I have Broadsoft VoIP installed. And yes the exe is running but no window at all.

Firefox 3.6.6 freezes on my Vista machine about once a day. If I catch it quick enough to go to task manager and end the non-responding Firefox, I can restart it. If I wait, the machine locks up requiring a hard shutdown.

I too, suspect it is an addon extension problem.

Same problem here. Or similar, at least. I don't get any output from firefox. No window, no messages.

I run Ubuntu 10.04, "firefox" and "firefox-bin" show up in the process list but they are slleping on "do_wait" and "poll_schedule_timeout", respectively.

I haven't found any useful log file info...

By the way, I have lost Firefox in 3 machines with Xp I use (My notebook, Desktop office and Desktop home)

Running Windows Seven. Once Updated to 3.6.6 it will not connect to the internet. Neither will Googel Chrome nor IE. Once uninstalled and 3.6.3 re-installed all browsers work fine and internet connection works properly. Ran tests on my wireless adapter it says sytem conflict when 3.6.6 installed and functioning properly with 3.6.3 installed. Strange.

My firefox wont update to the new version. Runing windows 7 64 bit. Tried it in safemode and under a new profile but still no joy.

Seeing as some of you have problems I dont think I will bother with this update.

If I create and use a new profile, FF starts fine. So my old profile seems incompatible with the update. (Safe mode makes no difference, no output in the terminal either)

Is there a way to transfer all the stored password from my old profile to a new one? Ideas, anyone?

I had the same problem, Fix.

Yes, it worked!

Thanks for the fix!

Worked for me as well! On Kubuntu 10.04

What does "moving away the file" mean? Move it where?

move it anywhere

I'm running Vista and I am having the same problem. I have gone back to the previous version and everything is running fine.

Instead of moving the file, I went back to the previous version 3.6.4 since 3.6.6 is buggy and was not ready for launch.

Several of my addons were disabled as they weren't compatible - so best to wait until the bugs get worked out.
