This issue started happening right after updating to Firefox 42, I think. What happens is that every time my Windows 10 laptop boots up and I start Firefox (and sometimes after signing out of and back into my Windows profile), the browser acts as if it just updated, and it also checks for addon compatibility [see image 1]. I get the "Firefox + Windows 10 = Perfect Together" page, and my homepage has been reset to "search.domaincentar.com" [see image 2],although it shows a Google logo. My theme and some miscellaneous browser settings are gone too.
I change all these settings back to the way they were, but this happens every time I reboot without fail. Here are the things I've tried:
Creating a new Firefox profile.
Deleting prefs.js and other possible culprit files in my current profile. (no user.js present)
Reinstalling Firefox completely.
Updating to Firefox 43 beta.
Deleting the Mozilla folder from %appdata%.
...and different combinations of all the above. The bare fact is that even after a COMPLETE wipe of Firefox from my laptop, including removing all my profile info to a separate location, this keeps happening. The homepage being reset to a weird search page seems like adware or malware, but I haven't been able to detect any via scan or looking in my addons. I am truly baffled, and at your mercy.
