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.

Completely unusable. Doesn't seem to do anything. No instructions. Website says it is no longer supported.

Makes reddit usable after their new layout changes. Seriously if you use this for reddit, please donate. 100% worth it.

I know it hasn't been updated in 2 months, so I'm guessing that's why lately it takes dial-up amounts of time to load pictures in Reddit while using this RES now. With photo preview, when you mouse over the picture, it loads from top down sooooooo slow. I removed RES and it works great. Almost instant loads. Hope someone updates it sometime.
