Why I can't modify "always check if Firefox is your default browser"? I checked my settings today and this option is unavailable. I can modify it only if Firefox is NOT used as defaut. Also this setting gets off after browser reinstallation, even if it was ON before. It seemed that Firefox can't save it...Can you help me?

Are there any prefs that show locked on the about:config page?

Can you post your Troubleshooting information?

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

Try to start Firefox in Safe Mode to see if that has effect.

  • Windows: hold down the Shift key while starting Firefox
  • Mac: hold down the Options key while starting Firefox

Safe Mode didn't help me, this option is still unavailable...And what did you mean when you said "locked in about:config"? I opened it but there was a lot of text so how can I find what you said?

I'm not looking at their systems, I'm looking at yours. Disable Bitdefender and try it out.


Are they also running into Firefox problems?

If other people have the same problem without Bitdefender it means that Bitdefender is not the cause of this problem. And I've tried to switch it off today - it didn't help...
