What did the installation of CorelDRAW Graphics Suite X6 changed in the system because after that Firefox crashes every time when opened?

Question

My system worked normally but after I installation CorelDRAW Graphics Suite X6 Firefox crashes every time I try to open it. I've tried disabling plugins and add-ons but with no success. Reinstallation of Firefox hasn't helped. But as I this has happened to me on a couple of other computers too, I've been able pin point the source of problem to installation of CorelDRAW Graphics Suite X6 (and earlier versions, too).
Firefox can be opened without problems in safe mode or in Windows XP SP3 compatiblity mode. Does Firefox use some different system components then?
I am using 32-bit Windows7 and latest version of Firefox.

Answer 1

It is possible that the CorelDRAW program installed extra fonts on your computer and that Firefox is having a problem with one or more of them.
You can use one of these to start Firefox in <u>Safe mode</u>:
*On Windows, hold down the Shift key while starting Firefox with a double-click on the Firefox desktop shortcut
*On Mac, hold down the Options key while starting Firefox
*Help > Restart with Add-ons Disabled

You can also do a malware check with some malware scanning programs on the Windows computer.<br />
You need to scan with all programs because each program detects different malware.<br />
Make sure that you update each program to get the latest version of their databases before doing a scan.
