I keep having problems with firefox blocking my searches or when it goes through changing the search site to Bing. I have tried the remedies in the forum pages
When I type in a word or site name without adding ".com," I get "adcenterexpress" showing up in the search bar or it might switch to Bing if I put it in the Google search bar(sometimes adcenterexpress come up there too). I do not want to use Bing. I have tried every relatable advice page on your site without success in changing this. What should I do? Turning off McAfee does not help. I turned off Firefox tracking protection without benefit. Nothing in your forum has helped and keeps taking you in circles.

Hello,
It looks like you may have malicious extensions installed.
Try Firefox Safe Mode to see if the problem goes away. Firefox Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:
- Click the menu button
, click Help 
and select Restart with Add-ons Disabled.
If Firefox is not running, you can start Firefox in Safe Mode as follows:
- On Windows: Hold the Shift key when you open the Firefox desktop or Start menu shortcut.
- On Mac: Hold the option key while starting Firefox.
- On Linux: Quit Firefox, go to your Terminal and run firefox -safe-mode
(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
When the Firefox Safe Mode window appears, select "Start in Safe Mode".
If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to find the cause.
To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.
You can also run a malware scan.
Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.
You can try these free programs to scan for malware, which work with your existing antivirus software:
