Try to start Firefox in Troubleshoot Mode to see if that works.

• Windows: hold down the Shift key while starting Firefox
• Mac: hold down the Options key while starting Firefox

No I still could not open FF. So frustating.

What happens when you try to launch Firefox?

As I click on FF - wherever I am i.e. clicking shortcut, or going to the menu and clicking on it or going to the FF folder and clicking on it - it goes looks as if opening FF and then immediately Bing opens

Bing is a search engine so it may be opening in Firefox or do you mean the Edge browser? If the former is the case, you may be able to change your search engine settings or your home page settings.

If the wrong browser is opening, you can make Firefox your default browser. If that doesn't work, there is something on your OS which you need to change.

Are you using Firefox on a different system to post in this thread? as your fist post details show you used Firefox 112.0 on Windows 10 to post this thread. Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/112.0

Firefox is a web browser and Bing is a search engine like Google and DuckDuckGo are. The company Mozilla does not have a search engine of their own.

Terry. I've already tried all the options that you provide. That is where I started - in the FF frequently asked questions as per Mozzilla page. Needless to say nothing worked. I agree that there is something in my OS that need to change but what?

James: I used FF as a browswer, and used Google as my search engine. I thought you guys would understand that. Sorry. Currently I can not open anything. When clicking on anything it goes straight to Bing - no browser, no search engine.

I don't know of any way of opening the bing website without a browser. Have a look at the Firefox launcher you are using. If it is faulty, can you remove it and create a new one?

Do a clean reinstall of the current Firefox release and delete the Firefox program folder before installing a fresh copy of the current Firefox release.

• download the Firefox installer and save the file to the desktop
  *https://www.mozilla.org/en-US/firefox/all/#product-desktop-release

If possible uninstall your current Firefox version to cleanup the Windows Registry and settings in security software.

• do NOT remove "personal data" when you uninstall the current Firefox version, because this will remove all profile folders and you lose personal data like bookmarks and passwords including personal data in profiles created by other Firefox versions

Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.

• (64-bit Firefox) "C:\Program Files\Mozilla Firefox\"
• (32-bit Firefox) "C:\Program Files (x86)\Mozilla Firefox\"

• it is important to delete the Firefox program folder to remove all the files and make sure there are no problems with files that were leftover after uninstalling

Your personal data like bookmarks is stored in the Firefox profile folder, so you won't lose personal data when you reinstall or update Firefox, but make sure NOT to remove personal data when you uninstall Firefox as that will remove all Firefox profile folders and you lose your personal data.

If you keep having problems, you can create a new profile as a quick test to see if your current profile is causing the problem.

Reinstall Firefox

Terry, core-el : thanks for the advice. I managed to do another refresh (the option you get when you try and uninstall FF) and it worked. I have a working FF. It is a bother as I still could not uninstall the previous version - FF automatically installed it to a different location.

Thanks heaps.
