I have a strange issue: When I launch Firefox 12 nothing happen and Windows becomes very very slow, only the explorer. For example, when I hover the mouse over the task bar the tool tip takes 1 second to appear, and opening start menu takes also long time.

But, if you switch to a running application (Chrome for example), it is responding properly, and you can open a website and interact with it. After a while (about 15 minutes) suddenly Firefox starts, and Windows gets normal.

I tried to scan for viruses with no luck, I'm using Microsoft Security Essentials.

I tried to run Firefox in safe mode also with no luck.

Edit:

  • I tried to update to v13.

  • I tried to delete the profile and created new one, disabling all the extensions.

Doesn't solve anything! Can anyone guide me how to figure out if there is a trojan or spyware?

Have you tried a) disabling any Firefox extensions you may have installed or b) uninstalling and reinstalling Firefox itself? –  ChrisF Jun 15 '12 at 10:34
    
Update Firefox. If that doesn't work nuke your Firefox profile. –  Ramhound Jun 15 '12 at 10:35
    
I tried to disable all extensions, but I think running firefox in safe mode does that automatically –  Nour Sabouny Jun 15 '12 at 10:39

I figured out the problem, it turned out that Babylon translator is the problem, I don't know how it is doing it, but even if I removed firefox, deleted all the data and profile files, babylon still can plug itself into firefox again after installation, and make it hang, and make the PC slower.

I used the process monitor, to see what is going on when I start firefox, and I saw babylon starts a lot of activites ( like modifying a file in firefox folders ).
