Add support columns for Firefox on iOS

[valioDOTch]

Please consider adding a support column for Firefox on iOS if possible.

As with Chrome on iOS, support is ~99% the same as Safari on iOS as it uses the same underlying engine. So not a priority to add this.

@Fyrd OK but some official hint would be nice though.

https://caniuse.com/#feat=input-datetime says for Firefox:
Partial support refers to supporting date and time input types, but not datetime-local, month or week.

On iOS 12.0 Firefox Version 13.2 (11866) supports type="date", type="time", type="datetime-local", type="month" and displays the native widgets - which is very nice and good to know. type="week" doesn’t seem to be supported.

Like seriously, this info is super hard to find, would be nice to have a little footnote somewhere explaining this.

@Fyrd Please reconsider adding ios_firefox tag to target Firefox on iOS. It does not act like iOS safari, or anything else on iOS.

For example, iOS Firefox messes up error contents by thinking its not in the same domain with server. We get these a lot from iOS firefox, and there is little we can do about them. The problem is not on our side. All our code is running on the same domain, and hence we omit adding Access-Control-Allow-Origin header tag to prevent scripts from other domains.

So please, reconsider adding ios_firefox tag so we can stop receiving no script error alerts from these ill-advised users.
