So, not automatically finding the login(s) associated with the page I'm on is really the thing that makes the addon useless in Pale Moon, well that and that if I do search for it manually it opens it in the wrong browser. The biggest problem is not detecting the page I'm on because over the years I have accumulated a large number of logins from various sites, most of which are used rarely or never but I don't delete them because I never know if I will be back at that site someday. In other words it behaves exactly the same as if I click the 1Password icon in OS X's top menu bar. It cannot detect the page I am currently on, and if I select Logins and then select the page I'm on from the list of logins, it will open it in the original Firefox, not in Pale Moon. What happens if I use that shortcut is that 1Password mini opens, but it does not seem to recognize the browser at all. New Moon) users? Again, keep in mind there are official builds of Pale Moon for Windows and Linux, so even if you don't feel it's worth your time to support 'unofficial' builds of browsers, I suspect that if you built an extension for the Mac version it would work on the Windows and Linux versions as well. I'm sure you supported that older version of Firefox at one time is there any chance you'd consider dusting off that older extension and making it available for Pale Moon (a.k.a. Apparently an extension has to be compatible with Firefox 24.9 or earlier, or it doesn't work. Nevertheless it seems to work well, my only real issue is that the 1Passwork Firefox extension won't install. I do wish it were not labelled 'unofficial' but apparently they only make 'official' builds for Windows and Linux.

Because of recent changes in Firefox that have made it far less usable and much slower, I installed PaleMoon Mac 26.0.0 (unofficial) from this site:
