My Firefox browser is broken, I can open Firefox but I can not do anything it will not respond, clicking anywhere prompts a "Firefox is not responding" error message, I was able to "refresh" Firefox once with zero results, I have tried uninstalling Firefox yet it will not uninstall the uninstallation window comes up yet no matter how long it sits open nothing happens, I have tried reinstalling Firefox with no results, the installation freezes just before completing and says "Firefox could not be installed". I have been using Firefox as my primary browser for a long time but I am unable to use it in any way now. All other browsers are working fine no issues but I do prefer Firefox and would like to continue to do so. What do you suggest?
