I have been trying to upgrade to Windows 10 and after installation, my adobe flash plugin crashes on every page! I updated mozilla and adobe flash and it still crashes..then I noticed in my antivirus that firefoxsetup.exe was blocked! I have no problems with Internet explorer, but truly prefer Firefox!

hi, no original mozilla-built or provided setup file will have that name, so it is likely that you have downloaded some third-party adware-infected installer.

please always download software directly from its developers, and in the case of firefox only at its official location at www.mozilla.org/firefox !
