embedded youtube player hell slow with noscript

[shodan]

firefox 3.0.14 + noscript 1.9.8.86 result in youtube player being hell slow and freezing the browser for me.

eg. when i open http://habrahabr.ru/blogs/algorithm/68323/#habracut in a fresh started (!) browser and click play, firefox.exe maxes out one of the cores for ~10-12 seconds, then starts to buffer the data and play the video. it does not respond to anything in the meantime either.

disabling noscript helps. actually for the sake of the experiment i disabled every other extension and plugin except noscript.

what version of noscript do i downgrade to and where do i get it?

thanks.

disabling noscript helps

Only helps, or the issue is gone?


I get the same CPU load (~50%) while the video plays.
Starting the video (the time between clicking the > "button" & the video responding) is only very slightly slower with NoScript.

A few things I would look at.
1) Instead of downgrading, upgrade to the development build.
2) ClearClick. Disable that & see if that helps out.
3) FF (in particular) does a lot of housekeeping (things like that Google "malware" file that it seems to always want to reindex) when it loads, & when it shuts down & (in particular) on lower end machines really puts a drag (on my) system.
4) Flash can be a hog. (Not a lot you can do about that.)

Disabling ClearClick removed the issue. Thanks!
