Basically the title,
I’m stuck with an old version when it was posted on Github before the takedown and I’m out of the loop, thanks guys!
Thanks! So I understand that we have to manually install the xpi from here 👌
Yes.
Hot tip. You can enable ‘Install extension from file’ in mobile Firefox apps (Firefox, Fennec, Mull etc) by going to Settings > About Firefox (or About Fennec etc) > Tapping the name 5 times.
You should see a message about debug mode being enabled and the ‘Install extention from file’ option should be in the Advanced section of your brower settings.
