I-Firefox iOS Isithangami Sokwesekwa

This may be the wrong forum for this question. If so, I apologise.

Is it possible to use Firefox to find out when a viewed website was last updated? I know that in another browser, it is but cannot see a way of doing it with Firefox.

Cheers

Ian

today the yahoo mail app on my iphone X stopped working. When I tap on the app the first screen appears and then disappears - no message or error. I've tried rebooting the Iphone and reloading the app. I've run out of ideas!
