I upgraded to Windows 11 home and since I did when I open Firefox I keep getting the pink and gray bar with the skull telling me my computer is under remote control. If I close Firefox then reopen it the error goes away, BUT, (isn't there always a but) some websites don't totally load. Please tell me there is a fix?

Your System Details shows that you have a user.js file in the profile folder to initialize prefs each time Firefox starts. The user.js file will only be present if you or other software has created this file and normally won't be present.

You can check its content with a text editor (right-click: "Open with"; do not double-click). The user.js file is read each time Firefox is started and initializes preferences to the value specified in this file, so preferences set via user.js can only be changed temporarily for the current session.

You can delete the user.js file if you didn't create this file yourself.

You need to reset the prefs set via user.js on the about:config page so keep a note of the content of user.js or first rename the file to userOLD.js.
