Firefox wont start at all

more options

In the last few days my browser simply do not start. One day it worked fine the other day nothing, not even an error message. There was no windows update as far I remember.

I have tried the basic options. Restarting computer and reinstall did not help.

Other browsers work fine. I could even import my Firefox passwords, bookmarks, etc to a new browser.

Any idea what can I try?

Nevermind. Eset Smart Security' s firewall got my Firefox. I had to delete the old rule in the firewall and set it to automatic. Probably a Firefox or an Eset update tricked me.
