Flash installer updating secondary browser instead of default
I have three Windows 7 computers. All of them use Firefox 52.5.3esr as the default browser, and they all also have IE 11 installed for secondary use. I have Flash player, as always, set to notify me of updates, but let me decide whether to install.
Normally, if the Flash "Update Available" dialog appears on the desktop (usually soon after system start), and I proceed with the install, what it updates is the default browser, Firefox. This is how it still works on two of the computers. But on the third computer, for the last couple installs, it has updated IE instead of Firefox. (I double-checked to ensure Firefox is still set as the default browser on that computer.)
Any ideas on why this could be happening, and how to remedy it (other than remembering that Flash is updating the wrong browser on that computer, and that I need to do a manual Firefox update)? Thanks.
