Firefox will not load on my PC (Windows 10). I've been through the suggestions and so far have tried: Uninstall/reinstall a few times including with security turned off and rebooting the PC afterwards. It looks like it may not finish the install. The status bar completes and then the dialog box disappears. I don't get a "finished" message as with most installs nor a prompt to open the app or make it the default browser etc. Tried to set up a new profile as suggested. I tried all the different options to get into Profile Manager and none worked. Checked Task Manager. There is no other copy running. I had the latest version installed and the last Windows update was a couple of weeks ago. It worked fine yesterday. I have the android version on my phone and tablet. I welcome any suggestions! Firefox is by far my favourite browser. Thank you.
