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?

Update / disable BitDefender

Hello. SFC detect noting. Also I have lastes Nvidia drivers (I use Experience and always update them). Regarding Bitdefender - I'm not sure that it is the cause if this problem. I asked other people about this issue and they have just the same, but they don't have Bitdefender in their sytems...

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...

Note: Some software, like Advanced SystemCare with Surfing Protection, can protect files in the Firefox profile folder against changes. If you have such software then check the settings or uninstall this software.

Start your Computer in safe mode with networking.

Starting The Computer In Safe Mode;
Free Online Encyclopedia

Start Firefox. Make some changes. Close Firefox. Wait about 10 seconds to close. Start Firefox. Were your changes changed back, or retained?
