Just to be clear, the version I am running, and its full name is "Flash Video Downloader 4.0.5." (that's the version I want to stick with and why I don't want to be annoyed with any updates.) When I enter it using that full name it will always come up immediately.
EDIT:
edit2: Version 4.0.5.1-signed was called "flash video downloader". I put that in the black list and it is no longer checked so the AUC icon doesn't change, no alerts, etc. You should probably install the signed version soon or it will be blocked from running sometime around Firefox 42 (unless you are on a Nightly build or a few other exceptions.)
You put it in the blacklist, does that mean I don't have to do anything further? As far as it being dropped in 42, at that point I will remove it entirely. It now installs unwanted extraneous crap. The 4.0.5, which is old but still works, is the last version that didn't do that.
EDIT: Oh, you mean there is a signed 4.0.5.1? Thanks, I will have to look into that.
