Don't know if this is related, but when I just ran getFlash11 extension I got
/usr/local/bin/getFlash11.sh: line 82: file: command not found
Downloading Adobe Flash...
Error:Downloading source. Exiting.
AFAIK all my extensions are up to date.

Edit: As a workaround, I downloaded the latest Flash11 tar with browser, and then ran a modified version of coreplayer2's getFlash11.sh script with the download commands commented out. This appears to install the latest version of Flash11 -- at least Firefox doesn't block it anymore...
