Bring back old devices

[maxnordlund]

In #28 a lot of old devices got removed, leaving mostly high-end ones enabled. What is the reasoning¹ behind removing those devices?

I can only speak for myself, but I need to test the sites I'm developing on older devices, with a bad connection. Responsive design mode helps tremendously with that, I love it. I just wish it had more devices to choose from :)

Can these be brought back? Maybe behind a flag in about:config if nothing else.

I also wonder if Mozilla can pull some statistics for devices, and/or screens in use? Really it's the latter I'm mostly interested in as that's what I'll target using a @media query.

¹ I couldn't figure out why, as the PR didn't have a description and the commit message is just Update device list.

You're right, I didn't give a reason in #28.

We wanted bring some new devices in, but at the same time keep the list of available device to a reasonable amount. The current selection is based on data we can see in the Play Store analytics, so it reflects the market of Firefox users to some extend.

Re: including older devices, I will think about it. With the market fragmentation we experience on Android it will be hard to cover everything. The goal here is to balance a reasonable amount of offered devices against a wide range of screen sizes and market share.

If you feel we're missing out on obvious choices, please let me know :)
