No working extension for firefox mobile, and on desktop Firefox it is buggy. For example sometimes it only fills half of the needed password fields (e.g. fills username into password field and leaves username field empty).. one cannot at the moment export passwords, it simply won't function and upon research I found out this issue has been well reported since at least February 2020 in their own forums, and their only response to it is that they are "investigating" the issue, but no solution after many months. I am not sure if they are just incompetent or actively trying to hold peoples passwords hostage so they can't replace the buggy mess with a competent password manager. I give 2 stars because it used to work reasonably well for a period and the free functions are acceptable.
