Wonderfull addon, I just wish it was marked as "compatible with Firefox on Android" and let me use it on my phone. I don't see why it would be incompatible.

As of 2024, works the best out of all other extensions for Firefox that do the same! The others either don't work on old.reddit.com, don't work at all, or have weird bugs causing webpage to shift upwards. Thanks!

I like this one more than the most popular one because it has the button within reddit itself, and has a neat animation! :)
