in reply to Save File As --filenames
I see it too.
It looks like it depends on the URL used to access the page. Visit each of these links and then try saving them, see if you get the same results that I do (if these URLs use a different domain than you usually do, you won't stay logged in):
The only difference is the "index.pl" in the URL.
Update: I'd suspect that if you took index.pl out of whatever bookmark you use as your entry point to perlmonks, the issue would disappear.
BTW, I got these results on Firefox 1.0.7, Mozilla 1.7.11 on Debian unstable.
Update 2: edited first update
