nsAppshell - this program is not responding

[fsyozabil]

My pc is very slow. It's a AMD Athlon 3200 running Windows XP Home sp3. I'm using Firefox. I get this error warning each time I shut down. After a long wait I get a box with nsAppshell Event Window - this program is not responding. If I log off and log in afresh, things are a bit quicker than before. I don't get the error box if I don't use Firefox. I may have done something silly because I've got a lot of programs on a usb hard drive instead of the C drive because of space. I havn't done anything intentionally in the way of partitioning, although i have 2 Gb unallocated space on the C drive. Any ideas anyone?:rolleyes:

I'm starting Firefox in safe mode

 

I read that the problem could be with extensions or add-ons to Firefox and starting it up in safe mode would disable all of them. I've done this, and the problem seems to have gone, and I shall see if it is a particular extension or add-on causing the problem.

You beat me too it on the add ons or plugins.

Open firefox then click on tools, then add ons, select extensions, click on each and disable, do this also with plugins. Then one by one re- enable them till you get to the one causing the problem. Either totally remove it, or if needed remove then re-install and hopefully that should cure it.

A bit long winded if you have a lot of add ons, but is the only sure way to find the problem one.

I read somewhere that an add on called Ubiquity can cause this problem.

If you have this one then I would delete this one first, and try again.

I agree with Nev,it's a case of one at a time.
