When I start Firefox for the first time, 1 Firefox.exe shows up in the Task Manager (8,180K), but Firefox doesn't start. When I click on it again, a second Firefox.exe shows in the Task Manager, and Firefox opens. Is the first one a Trojan?
I'm using version 3.6.12 on Windows XP. The icon points to C:\Program Files\Mozilla Firefox\Firefox.exe. The Properties of that file look okay.

No, most likely not. I reckon you got some antivirus software on your machine, don't you?
Sometimes Firefox does load into memory but won't show your start page.
Simply open the task manager, click on the "Processes" tab and kill the (two or more) firefox.exe processes you've just created. Double-click your Firefox icon and everything should be back to normal.
