Just what I was looking for. I use this addon in combination with some scripts, because the scripts don't seem to work 100% of the time.

However your addon doesn't seem to fix instagram, facebook url tracking!

https://l.facebook.com/l.php?u=

This is why I have blocked these sites with 0.0.0.0 with uBlockOrigin ... this way I can manually copy the links without the tracking.

Firstly, thank you for your add-on.

Secondly, I hope your add-on never will be "another CleanURL". I remember time ago, CleanURL started as a very simple, basic and focused add-on. Unfortunately along the time, it became a bloated monster, a risk for privacy and a browser performance killer.

Personally I believe that there is no privacy or security without browser performance. So please, always develop your add-on keeping in mind browser performance.

Another point: There is no need for endless tracker lists that most of the users never are going to block. Therefore, the basic trackers are more than enough to be blocked. Any other specific tracker can be added by the user, for example if in the future you add an option for customizations.

In short, focus on browser performance, the basic list of trackers, and an option of customizations... IMO that's all what your add-on needs!
