Firefox 3.5.1 not closing properly; 'already running' message.

[slipd]

Hi guys,

Since upgrading to v3.5.1 I'm regularly getting the 'firefox is already running' message if I close ff and then try to run another instance of it. Atm, I've been going into task manager and ending the process manually which is starting to get a bit tiresome now...

I've had a quick google and it seems that are a lot of sufferers out there, but every page I looked at had a different solution

Before I start editing registries and deleting files etc, is there any definitive fix going around on here that works?

Cheers

Nope, not using foxytunes.

I'm currently only using: adblock plus, downloadthemall!, ff companion for ebay, noscript, oldbar and a skype plugin.

SW.

I've got this too since installing 3.5.1. Even if left for 2hrs+, the process never quits; it just sits there using 60MB of memory and loads up both cores of my E8400 to 50% each. The only solution is to manually quit the process.

My ff process seems to always sit at around the 60mb when i go into task manager... maybe it's because we both have the same cpu

I haven't checked cpu usage, but i will the next time it happens!

IIRC, that ms.net framework assistant extension has been present on my system for quite a while.

Since disabling that extension I've not encountered the hang on exit problem. Too early to say whether it fixed it permanently though - will report back

Since upgrading to 3.5.2, I haven't (touch wood!) encountered the problem...

And that's with the .NET extension enabled
