For many yrs, Firefox has been my default browser ( it is set as my default browser ) but for thew past few weeks when I click on the Firefox icon, MSN / Bing pops up. I was able in the past to tap on MSN and the past history FIREFOX would appear and I could use FIREFOX. I have tried to uninstall Firefox a few times then reinstall but the problem is still there. I CANNOT uninstall MSN ?? Now, that I back from a buisness trip I cannot bring up Firefox browser, at all ! I get the Firefox banner page about pug ins/mobile, etc.. I WANT MY FIREFOX BACK. Please, any suggestions..I am NOT tech savvy . John

Try:


You can open the about:config page via the location bar and do a search for bing via the Filter at the top of that page.

You can reset all bing related prefs via the right-click context menu to their default values.

To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.
You can use the Filter bar at to top of the about:config page to locate a pref more easily.
