I have three browsers on my Dell Latitude E 6320 Windows 10 operating system namely Edge, Firefox and Google Chrome. Firefox is my favorite browser among the three which has been working normally untill a fews ago I decided to make Firefox as my default browser. Of recent when I click on the Firefox Icon to surf the internet, a small window appears making reference to drive C:\windows\system32\......... with something like .dll at the end of the path and some statements which disappear before I can completely read the contents of the small window. As the small window disappears, Firefox launches up and remained launched with nothing else happening. Even when I type Firefox address in the address bar and press the enter key, nothing happens. The text message "Hand shake" with any site address typed into the address bar that is usually displayed at the lower left handside of Firefox page before the required website is connected and displayed, is no longer been displayed. I have uninstalled the 79 version and reinstalled the same version which I have just downloaded for resolving the problem, thinking that the uninstalled one has been corrupted, but the problem still remains. This is the problem I am experiencing with Firefox browser presently hence I am asking for assistance of how to solve this problem from the community. Thank you and for looking forward to your response.
