Bookmarklet does not work in Firefox Mobile (iOS / iPadOS)

[nikkuneko]

Adding the javascript bookmarklet to Firefox Mobile does not work. It has been working well in iOS Safari (essentially since launch), but when trying to create and open the bookmarklet in FF, it asks to open it in an “external app” instead of executing the javascript.

after a little digging, this seems to be more of a Firefox issue than a MLTSHP issue. (see: https://bugzilla.mozilla.org/show_bug.cgi?id=1296636 and mozilla-mobile/firefox-ios#5626)

that said, seemed worthwhile to make the issue known and trackable here.
