Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

• Do NOT click the Reset button on the Safe mode start window or otherwise make changes.

The crashes occure for users NOT for the administrator.

So Firefox is crashing because of beid35cardlayer.dll, which is apparently a virus. Please read Troubleshoot Firefox issues caused by malware

Question owner

beid35cardlayer.dll is a beidcardlayer of the Belgian Government and part of the beid35cardlayer.dll plug-in.

Alright, in that case please disable the plugin and contact whomever you received it from for an update.

Question owner

I received it from the Belgian Government.

May I remember, that the crashes ONLY occur by users, and NOT by the administrator.

There is no possiblility to start in safe-mode; because the first window of Firefox does not appear.

Hold down the shift key while you open Firefox, you can open Firefox in Safe Mode.

Chosen Solution

Started in Safe Mode by holding down the shift key while starting Firefox. Clicked on Reset Firefox. Started in Safe mode. Everything OK. Shut down PC. Started PC. Firefox started without problems.

Cor-el and Tylerdowner thanks for your help.
