So I did. Only, when I tried to install it, the installation died in mid-install and never completed. I've had to kill the installation process via the Task Manager. Ever since then, Flash in my FF is broken. It works about 30% of the time, and the remaining time I get a pop-up window telling me that the plug-in has performed an illegal operation (I'm not 100% sure of the wording, something to that effect) and giving me the option to not be notified again of it not working throughout the browser session, if I tick off the option.
Since then I've tried just about everything to install it again - but installation off the downloadable Flash executable installer always hangs as it has originally. Web installs seem to work just fine, but as soon as I close everything down and start FF anew, it's back to being broken.
Since Flash doesn't show as an installed plug-in in FF, I can't even remove it to attempt to reinstall it. In short, I don't see any obvious way to fix it. I hope someone here can help me out, because it's really starting to piss me off.
