I can mention the ones I'm using on my Firefox for Android. The most important, without which mobile web would be unusable for me are: uBlock Origin (AdBlock Plus also available) and HTTPS Everywhere. I would also use NoScript, to completely block Javascript on websites I don't trust, but unfortunately the version for Firefox Mobile is not submitted to addons.mozilla.org and I don't trust extensions that aren't submitted there. Instead I've been using Ghostery lately, not sure what to think of it. I was also using the LastPass Password Manager, until I migrated to my own solution. I also have Pocket Hits and the Wikipedia Panel for suggesting stuff to read. Because I'm a developer, many times I open JSON links from emails and for formatting, the JSONovich extension seems to work on my Android Firefox.
