nice… at the moment i have a strong interest in something that works from the other direction — is it possible to run code on installation that can clean out an old version of your extension? (if a change of GUIDs becomes necessary, for instance)

Nice concept, but I am a little dumb here. I am a newbie, could you give me complete step by step to do this clean up with the code? I really appreciate your help.

Great idea,
I was looking for this functionality and found ‘Adding entries to the uninstall log’ on MozillaZine. Unfortunately that method needs to add each file separately to the Uninstall file in the extension directory. In my case I save a lot of web pages (implementing my own cache) and it would be too much files to add to the list. It seems to be much easier to delete my cache’s root directory recursively from a script on uninstall.
Thanks a lot.

I’m not any big programmer or anything but sometimes when i uninstall an extension from firefox and i check my profile folder i still see folders containing scripts n other stuff from the uninstalled extensions.. I’m not sure if this is supposed to be like tht, but if the solution u stated above can clean up those unnecesary files then yes it is a good idea that should be followed up

The code for this technique can be found in my FirefoxView extension.

Could you send me your example “uninstall” extension hook code?

Thanks too. I was looking for a post uninstall extension script or event but soon realized it didn’t exist yet. I would appreciate seeing code on using nsIExtensionManager for this purpose. Let’s hope an onuninstall event is added to make handling easier.

Awesome, I woul definitally like this for my QuickNOte/BBCode and WebMailCompose extensions, as the firefox uninstaller doesn’t get rid of prefs that I want removed.
Thanks once again alex.
