You seem to arbitrarily decide to eliminate numerous add-ons. For years I have been using and working with Scrapbook. By upgrading to Firefox Quantum, all of a sudden somebody decided to call this program 'legacy software' (whatever that is!) and pretty much eliminate it. I had many files on scrapbook which now I cannot access and seem to have just vaporized. This is not a professional way of running and managing a web browser used by millions. Who makes these decisions and based on what criteria you decide to eliminate add-ons without notification. Once an add-on is listed on your site, then one assumes that it could be used and will be there for the foreseeable future. If you want to eliminate whole bunch of add-ons then you need to have a much much stricter criteria for putting them in your list in the first place.

This is very disappointing
