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.

Did you install both at the same time? When was the last time the combination worked together correctly?

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?
