I want to make a Firefox extension that can store and retrieve data from a database. However I've only been finding solutions that would work locally for each user. I'd like every user to have access to the same database.

Is that possible?

You should try to learn and doing it by yourself first and only ask here when there are specific issues you're stuck with, instead of posting such kind of generic question of how-to.

By "locally", I think you mean via Web SQL or IndexedDB. They're called local database and their behaviors are totally different from what you're looking for.

I should haven't need to tell you to do this. Just in case. Of course first thing first you need to know how website is working for both front end and back end, not just local stuff, especially how they're communicating between each other. So you should know about HTTP request, Javascript, and AJAX.

What has it to do with Firefox extension?. Not just Firefox, browser extension is just another type of web page that overlaying the opened web page in all kind of browser. In Firefox the opened page is called activeTabs. The only difference from regular web page is you need to signup your account first, manifest.json file as your project root file, and it compile from command line with web-ext tools. In case if you're facing Cross-origin resource sharing (CORS) restriction, follow instructions HERE and allow the URL on server side.
