Hello,

As the subject stated i've finally found out, with long, various testings, that this combinations of plugins is causing the browser to hang on startup, with several pages left open on the session manager (moving, typing with keyboard and clicking with mouse in the meantime amplifies the bug). There are many times, when the browser hangs as well even while doing the same (moving, typing with keyboard or clicking with mouse) on normal webpages.

Tested even with a totally new profile on firefox6.0a, the bug is always reproducible.

I'm not 100% sure that Noscript is the source of this problem, but the interesting part is, that the bug only occurs after Noscript 2.1.0.1 (basically from 2.1.0.2rc2 and +). I'm using the 2.1.0.1 builds at the moment, and everything seems to be fine.

Tried a couple of versions with AutoPager (using 0.6.2.8 at the moment) and with AdblockPlus too (using 1.3.7a.2981 atm), but doesnt seems to have any positive effect if i move to previous versions.

Any clue what could the source of this strange bug be?

Does it happen with noscript.surrogate.enabled [url=http://kb..org/About:config]about:config[/url] preference set to false?
If it doesn't could you reduce your test case to the bare minimum necessary to reproduce?

Unfortunately yes. I've just tried it out and acts the same. Ill try to help you with the necessary steps

1 Install Firefox 6.0a nightly, or open a fresh profile to avoid settings conflicts.
2 Install latest AdblockPlus (or any pervious/dev version)
(2a you can load up any filter subscription on it if you want, i'm not sure if this has any effect to the bug at all.)
3 Install latest AutoPager (or any pervious/dev version)
4 Install any NoScript after 2.1.0.1 (basically you can go from 2.1.0.2rc2 and all the way up).
5 Now open a dozen of pages (like 10-20 or so) and after that, just close the bowser, making sure that it remembers them on session manager.
6 Finally, open the browser and when it loads slowly all the pages, click on the tabs randomly and rapidly, while pressing the keyboard arrow keys on the same way.
= The browser should hand from the stress.

The browser should hang* from the stress.

i almost forgot to mention, you will probably need the latest Add-on Compatibility Reporter (0.8.3) too, to force enable the unsupported extension versions.

I call false alarm on the topic.

This may had been a temporary firefox Nightly bug, or perhaps some kind of flash bug. With recent Nightly builds, and with the new Flash player 10.3.x this bug isn't reproducible anymore, no mater what NoScript version i use.

Sorry for disturbing, keep on good work.
