The desktop version of Facebook constantly lags behind the app and has weird bugs in Firefox where it will stop loading content, and when anything works on the mobile version of the website I'm honestly surprised.
And it's the same deal with Twitter. All sorts of bugs on mobile Firefox, some of them which I've been tripping over daily for years. When I worked at Twitter some years back, the web version was the red-headed stepchild of the clients. The engineers on it were nice and smart, but the team was underresourced and the client was treated as secondary to the mobile apps.
Boost, Relay and BaconReader are pretty good to browse Reddit in Android phones, and I know Apollo or narwhal are also good for iOS.
I wouldn’t be surprised if 80%+ of desktop logins are from bots and other bad actors.
As a part time social media manager, I use an android emulator to use Instagram and Facebook. The hoops I have to jump through to post a video story smh.
On a tangent:
I hope people stop labelling bad design as preventive measures. The bad design that do act as preventive measures are almost always accidental. Like yesterday, I spent 2 hours trying to find the cookies when I logged into a site that had some data. Only to discover the entire log in measure was a dummy interface. They were sending the data anyway but had a hacky solution to check if a user have attempted logging in. They were sending the data under the hood but they showed it only when the user logged in. Now, tell me is this a security measure? They did waste my time so wouldn't this fulfill their security goals?
That’s why I was thinking web would be easier because you can easily change your header and forego device attestation and emulator detection.
So if their infrastructure doesn't consider much for responsiveness between multiple screen size, I doubt the backend for the web version matter much for them.
I've also experienced problems with Firefox (especially with speed) when using any Google Suite apps (Docs, Sheets). I used to exclusively use Firefox, but some of my work as a volunteer requires social media account management (via Instagram) and GSuite apps for collaboration.
