You’re not alone, I’ve been using Firefox on Android for two years now, and I’ve had this problem from the beginning. The first time I launch Firefox and load a page it stops a quarter of the progression bar for ten seconds, and then loads fine. Once pas that everything works perfectly. It’s very annoying and I don’t know why this happens.

Change it to “Vertical”, if that’s what you mean.

I tried Liftoff and changed a few settings in the post style. Compact view on; Rounded corners, shadow and avatars all turned off; post title and header size to 13. It looks close to RIF. I’m not a fan of the card design that most apps use and it’s the reason why I used RIF all these years. I really hope that talklittle will also make an app for Lemmy/
