Several months ago I downloaded Uninstallability and Add-Remove Pro, both of which claim to overcome this problem, but they don't. The programs missing in Add/Remove Programs are also missing in both of the those.
At the moment, I'm trying to uninstall the Adblock extension in Firefox. I like the no-ads, but it's also causing freezeups. The Adblock site says to use Add/Remove Programs, but guess what... it isn't there. Nor in the other two uninstall programs.
I use Firefox 1.0.4 exclusively (never, ever open IE any more... too many meltdowns). Any ideas? Thanks a bunch!
