Some other unmentioned add-ons that I use frequently:

- Contextlets: https://addons.mozilla.org/en-US/firefox/addon/contextlets/

Adds context menu items that execute custom JavaScript. Think of it as an advanced version of bookmarklets that can use webextension APIs.

Example use case: Search for the selected text in multiple search engines in a new window with discarded tabs.

- Distill Web Monitor: https://addons.mozilla.org/en-US/firefox/addon/distill-web-m...

Monitor website changes and get notification popups, email, SMS or push notifications on change. There are other alternatives that have the same basic functionality but I stayed with Distill as it is more customizable.
