Update: I spoofed my user-agent string to get the normal mobile version in Firefox. It mostly works except images don't load! I'm done digging into this for now, but it's kinda bizarre.
I use Twitter on Firefox mobile and didn't know until this article that it's for some reason forcing an old ugly version. What UA string are you using? I tried the Android (Phone) one, and the Chrome one that the Phony extension provides but it still shows the ugly FF version of mobile twitter.
Any user-agent that mentions a recent Chrome and Android build should shows the new mobile.
I test one that has Chrome 43 and Android 5.0.2
Still, the no-image-load grind my gears, so I switched to desktop.
Twitter gives Firefox its "simple" app for feature phones. Go to it in your desktop browser to see the diff.
Desktop Firefox looks the same. Chrome is different though. Wonder why they do that?
Because they want to deliver a good experience to every user and redirecting to the simple version is the easiest way to do that. If they served mobile.twitter.com to Firefox for Android users they would have to test the site in Firefox for Android and since only like 12 people use Firefox for Android it's not worth their time to do so.
They're going to have to deliver (and test) one version or another. Or if they're not testing, they might as well send an untested normal version instead of the untested simple version.
Doesn't that @ symbol at the top take you to your mentions?
Oh, it does! That's an odd place to put it. Thanks!
