When I download the latest installer it comes up asking if I want to save the file which I do, then it comes up on my firefox downloads list but when I ask to run it and click ok in response to the usual warning it asks where I would like to extract the file to instead of executing the installer. If I go with it and extract the file it still won’t run thereafter but continues to ask me if I would like to extract it. I think it is some fault of the 7 zip program I use for managing compressed downloads because in the firefox downloads list it comes up as a 7z icon. So I removed this program but the problem continues (it even continues to come up as a 7z file which I can’t understand as I have double checked that 7zip has been removed from program list).
Help! What am I doing wrong?
