I've tried a handful of different reddit extensions for mobile, and this is the one that I like the best for interacting well with RES. Similarly to the other apps, you should disable a couple RES defaults (post and comment outlining). I like that this extension let's me easily use the RES account switcher. It also highlights unread comments (RES not required for that).

This is really promising but still pretty buggy. I check in with it every month or so and it's making progress but still not in a state I can use it.

Critically, it doesn't seem to cooperate with RES very well, and has nowhere near the equivalent features. If the choice is between turning off RES to use this or using Oldlander which takes RES into account, I'm using the latter.

This is hands-down the best Reddit extension. It's not too overloaded with unecessary features. The only features that are available are features that you would want. This has made my Reddit experience much better.

Great add-on. Best way to use Old Reddit on mobile and a good enough in the case of desktops.

This is an amazing add-on, I almost don't miss 3rd party apps anymore.
it's so much better than the new UI, or that janky official app.

Feature to use the add-on features only when in private browsing is rare but very useful.

Combined with sub filtering and the dark mode option, this addon gives me a quick, clean Reddit experience for new private windows without the hassle of having to login every time.
