If you want just to browse reddit then you can do that through teddit or libreddit front-end instances. And with extensions like Privacy Redirect [1] you can do it automatically.

There are also front-ends for twitter and instagram but these seem to be most faulty - sometimes it takes a while to reach a stable instance and extension tends to overwrite manually selected instances.

Edit: seems there's already a fork of mentioned extension but it's available for manual installation [2]
