I'm using Firefox 59. Since Quantum, I've had to experiment with numerous addons. This has caused issues and so I've come to rely on the Refresh option. However, there seems to no longer be an addon such as extension list dumper, which allowed for the the printing of a list of installed addons, prior to using Refresh; or any other way to get a list. This is needed to eliminate unnecessary addons and prevent endless searching for an addon that did work before the reset. Something like this could well prevent the over-reliance on addons/extensions and eliminate support queries as well. Is the ability to view and print installed addons in the configuration editor? Why not make the Addons Manager page printable with select and copy or just have the function in the options?
