Add-ons I've created
Request websites over secure https by default from the location bar instead of insecure http.
Overrides the Ctrl-Q and Command-Q shortcut so that you cannot accidentally quit Firefox. To quit anyway, use the 'Quit Firefox' menu item.
This add-on works for for all platforms (including macOS) and also in private browsing mode.
Displays anchors for all content in the current web page without breaking the layout.
Stop videos on YouTube from playing automatically until an explicit user gesture (clicking or pressing a key).
Real-time desktop notifications for Stack Exchange's inbox.
Works perfectly Rated 5 out of 5 stars
Ctrl + Q quits the browser by default. This is unfortunate, because the shortcut is close to Ctrl-W (= close current tab).
This add-on remaps Ctrl + Q to Ctrl + Shift + Q, and also works in recent Firefox versions (and e10s), so you won't close Firefox by accident any more.
Edit: This add-on does not meet my needs on macOS because on macOS there is also a Command-Q shortcut. After being fed up with losing my tabs multiple times, I published an add-on that replaces Command-Q too: https://addons.mozilla.org/en-US/firefox/addon/disable-ctrl-q-and-cmd-q/
Works perfectly, including Private browsing mode Rated 5 out of 5 stars
A big advantage of this add-on over the other similar add-ons is that this add-on only implements the promised functionality, and nothing else. There is no configuration: it just works without any surprises.
The add-on is open-source  and the author is very responsive: At first the add-on was not working in private browsing mode, so I contacted the author with a patch and a new update was published within a day.
Fix for Web Developer + NoScript Rated 5 out of 5 stars
The Web Developer toolbar is a must-have for web developers (arguably better than Firebug).
Unfortunately, the NoScript extension disables this feature. To save enable this feature again, I have written a Greasemonkey script: http://userscripts.org/scripts/show/133136
