[Ubuntu 9.10] Firefox 3.6 crashes on Youtube with enabled FG

[BlackVodka]

Well, first some system information:
Ubuntu 9.10 Karmic
2.6.31-19-generic-pae i686
Latest Sun-Java-Plugin and the Flashplugin from the Ubuntu-packet flashplugin-nonfree, which should be the latest
Addons in Firefox:
ADBlockPlus
VideoDownloadHelper
VLC/Totem/DivX-Plugins
I'm pretty sure it's a FlashGot-Bug because disabling the other Addons doesn't have any effect, but disabling FlashGot preventing Firefox of crashing like described below.

Bug-Description:
Well, it's a bit hard to explain but I'll try it:
When I try to open a page with java-content with all the above mentioned Addons enabled (an example, a german-chat-room can be found here: http://www.mainfranken-chat.de/zumchat) it works. But, with the java-page still opened in another window/tab and opening youtube Firefox crashes.
The last thing Firefox does is loading the page, the little indicator in the youtube-flash-applet moves to show the loading-progress and stops after about 1-2 sec. and firefox is 'dead'. The last thing firefox shows in the bottom-status area is -translated someting like- "Loading from cache<x>.c.youtube.com" (where <x> is a number).
The problem was in Firefox 3.5 whis was the reason for upgrading to FF 3.6.
Another point which may should be mentioned, the other Addons are for sure not responsible for this bug, with trial-and-error I found out that only disabling Flashgot let the crashes go away. At first I thought the Addon VideoDownloadHelper may be responsible again for this kind of problem (like it was about a year before) but it wasn't.

Okay, I hope you understand what I wrote before, I'm from Germany and my English might isn't as good as you're used to read so please excuse
If you need any more information for resolving this bug please let me now I'll do what I can to get it for you
Thanks in advantance,

So Java is a requisite for the crash?
As in if you were to disable Java, then you would get no crash?

What version of Java are you running?

[BlackVodka]

Oh I'm sorry I registered your question too late, had a lot of work
And yes, java is required for reproducing this crash.
I disabled FG the day when I created this topic and had no crashes since then...

For the java-version, I can tell the java-website reports it's the latest Version 6 Update 18..

...and of course, if I disable Flash Firefox's not crashing, too

Could you post your latest crash IDs from about:crashes when this happens?
Also, does it happen if you disable all your other add-ons except FlashGot?

[BlackVodka]

No, if I disable my other Add-Ons and keep FlashGot activated the issue appears, too.
And where can I find what you're meaning with 'about:crash' ? I just thought it's something like 'about:config' in the adressbar in Firefox but it isn't.

Sorry, it should be about:crashes, and yes it should be typed in the addressbar.
