ImgurViewer VS OpenImgur

ImgurViewer supports DeviantArt as well

For imgur on Android, I use ImgurViewer[1], which can display images using apis from a bunch of different sites (imgur, Reddit, gfycat, etc) as well as anything that ends with a common image extension. It's a far superior interface, and ability to swipe it away makes it more seamless, like it's just part of the app you opened it from.

For the browsing in Firefox, there's multiple extensions you can use to add the referrer and get the image directly instead of a redirect (see [2], though I'm not sure if it works on mobile)

Alternatively, use Rimgo[3], an alternative frontend to imgur. This page also lists several ways to automate redirects from imgur domains.

I use ImgurViewer

ImgurViewer (version 2.3.0): A little image viewer to open image and video links from external applications.

If you're looking for something on Android, this might be what you want.

For example, I want to block the website imgur.com, but not with a network filter since it would prevent me from accessing the images - I use a "image zoom" addon on desktop and ImgurViewer on Android. I never access the site directly and especially on mobile I here and there accidentally load a Imgur page with megabytes of various bloat.

Opengur is the Imgur client I'm using. Just know that it isn't updated since years and shows error while logging in, but you can browse the posts fine.
