Earlier today I tried to run Firefox and it didn't start, so I went and uninstalled it, then tried to reinstall it, but the installer would not pop up. But in the task manager I see Firefox 32bit installer is there.I've tried running it with my antivirus off. The installer worked before, and I was able to run Firefox. None of the other programs I've download are doing this.

please run a full scan of your system with the security software already in place and different tools like the free version of malwarebytes, adwcleaner, microsoft safety scanner & kaspersky security scan. also make sure that your security software isn't blocking the installation of firefox though...
