They managed to screw up all addons with expired cert.

How do Firefoxians manage to live without "Legacy Addons" ?
Just listing addons marked as Legacy on waterfox:

Multiple Tab Handler and TabMixPlus - both invaluable when you have lots of tabs.
https://addons.mozilla.org/en-US/firefox/addon/foxytab/ <-- this is a pale imitation

Dorando keyconfig - rebind keys to other shortcuts and scripts(create Privileged JS snippet run on custom keys - mini-extensions ). Probably most underrated extension ever.

Request Policy Continued - best control addon, very intuitive interface.

DownThemAll+DownThemAll Anti-contrainer - best mass downloader for Firefox.

Classic Theme Restorer - not essential,but great to minimize visual space use and reduce Australis quirks.

Table Tools2 - sorts table columns, a bit buggy but really useful for sites which don't have sorting.

Password Exporter - allows to export/import all passwords in text form.

Saved Password editor - edit passwords.

ViewSourceWith - view page source/file in custom program
