it does nothing. i can't even see the settings. the icon is grey

Reddit is an utterly useless cluttered mess without this.

Completely breaks both old and new reddit. Can't open images or videos and can't open links in new tab. Don't know what else it might break but I uninstalled it before I could find out.

Android Firefox allows you to install the addon, its obviously not intended for use on a mobile browser.
Desktop version seems to work quite well! I dig it!
It would be cool 😎 if there was a preset option that said 'Mobile' or Android, iOS, ipadOS.
Seems like it would take alot of work so its OK 👌.
Nice Piece of Kit as is though.
