It seems to work for me.

Where should I download that Flashget? Does it install some kind of extension, it seems, into Firefox? When I installed Flashget, it didn't install that extension.
If you crash in Firefox, what is the stacktrace you get?
Type about:crashes in the url bar, to see the breakpad reports?

You can download Flashget from here "http://www.filehippo.com/download_flashget/".
 and yes it does installs a extension named "Flashget3 Extension 1.0" and my error console states that "Error: uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIWindowsRegKey.open]"  nsresult: "0x80004005 (NS_ERROR_FAILURE)"  location: "JS frame :: chrome://flashget3/content/flashgetcommon.js :: GetflashgetREG :: line 25"  data: no]".
That's not a crash, but an uncaught exception caused by the extension.
This is very likely a problem in the extension itself and not a Firefox problem.
Group: core-security
Summary: crash if I download a file by choosing flashget option in the download prompt → Uncaught exception if I download a file by choosing flashget option in the download prompt
Did you install both at the same time? When was the last time the combination worked together correctly?

Till Yesterday they worked out quite well there was no problems with it but yesterday i updated my  firefox 3.6.8 to 3.6.10 and my flashget from 3.3 to 3.5 and only after that this always heppens.
I tried installing Flashget to get the Flashget extension for Firefox, but it doesn't install an extension for me.
So I don't know how to test this.
Where can I download the Flashget version that also installs the extension for Firefox?
