I am using an HP laptop and running the latest version of Windows. Firefox worked just fine about a week ago. However, after rebooting my computer the browser will not open at all anymore and nothing is working. I click the app and nothing happens. I've tried running it as an administrator. I've tried using the RUN commands, nothing. I've tried uninstalling and each time it tells me that Firefox must first be closed before I can uninstall, but it never opens anything in the first place for me to be able to close it and so I have to reboot my computer all over again to even uninstall the app. This is extremely frustrating because certain online applications I use for work are only compatible with Firefox. I've tried deleting temp folders in the program data, nothing. Please help! You have no phone support and this is a very pressing issue!
