At my wits end - Flash plugin crashes

A search here seems to show that nobody else has ever had this problem.

When I enable NoScript, I experience my Flash plugin crashing several times a day. It happens with YouTube, it happens with games (e.g. bubbleshooter), it happens, basically, with any and every site which uses Flash. It happens with my employer's intranet.

I'm not saying it happens every time I visit a page with Flash, but given its prevalence on the web, my "several times a day" is not an exaggeration.

I am pretty sure it is related to NoScript, because I tried disabling it, and for the week or two I ran without it I did not experience any plugin crashes. As soon as I turned it back on, I started getting them again.

The plugin "click to restart" has never, ever, not once worked. Once crashed, it stays crashed for all sites, all new tabs, even new windows. The only fix is to restart Firefox. Fortunately terminating the process and then restarting, so that I get my tabs all restored, works, but it is a right PITA do have to do this over and over again, day after day after day.

Any suggestions on where I can begin to look would be welcome.
