* Stylus - super useful. I auto color my dev/qa/prod environments so I don't do anything stupid. I color code the stocks in my brokerage account by strategy. I fix some of the terrible pastel colors in Microsoft products.
* Tab ReTitle+ - useful when you have multiple tabs open with identical titles.
* Zoom Tab auto-close+ - Closes Zoom tabs once opened.
* ColorZilla - A quick color-picker. I do some light web-dev and it's marginally more convenient than inspecting.
* Firefox Color - Quick browser changes, also do some custom stuff in UserChrome.css
* History Cleaner - Deletes my history after x weeks.
* LastPass - Just what I thought was best in 2016, not sure what's best these days but I'm somewhat satisfied
I find Firefox's built-in tracker blockers adequate for my usage these days (used to use uBlock Origin). Also, Firefox containers is a game changer for isolating work/personal or dev/qa.
I would also recommend learning how to write/use Bookmarklets and edit UserChrome.css for greater productivity/customization.
