What do you mean by rolling back?

What is in the unwanted windows?

Please explain the problem in detail. What happens? What is/are the exact error message(s) ?

What do you mean by rolling back? - page going back automatically to homepage

What is in the unwanted windows? - nothing, home page only

Please explain the problem in detail.What happens? - it does not happen with Google Chrome, Edge, or Brave browsers. Firefox keeps rolling back to homepage. It also opens new widows automatically. All work is lost because of this. I am working with Windows 10, Firefox 94.0.2 (64-bit). I am thinking about altenatives.

What is/are the exact error message(s) ? - there is no error message shown.

Set the home page. Wait a few moments, then close the browser.

Wait a bit, then Start Firefox using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?

before posting in this forum I already tried the troubeshooting option, but problem persists

Use these links to create a new profile. Use this new profile as is. Is the problem still there?

Thank you Fred. Yes, it worked for while. Now, the original problem is back again. I dont know what to do. Troubleshoot, refresh, creating new profiles, even re-install. I ve got only 4 extensions active now, namely uBlock Origin, AdBlock — best ad blocker, AutocopySelection2Clipboard, and SaveFrom.net helper. The hard drive is SSD 240gb, with 8gb ddr 3 RAM. It is first time in many years Firefox is giving me troubles.

I called for more help.

On "refresh" now. Removed 'SaveFrom.net helper' extension. Hoping that it will work out. How do I sent my browser data to mozilla developers?
