Gmail Death

On their mystifying path of "this browser no longer supports GMail", tonight was the death knell for it in my standard Opera browser, and it no longer seems to work in the latest backup browser I use either, Vivaldi, which does run just about everything.
It was chip chip chipping away at functionality for a while. One thing I lived with for months was not being able to change Subject lines in Replies.
And tonight, messages just plain will not open at all.

I can still see them all in the list though.

Naturally they have no intuitive postings online that I have found about this new phail.

Thus ensued an exploration of my options, revealing 3 or 4 other options so far (Pale Moon, Maxthon, Thorium, et al) and will see if they hold any hope.

I can also look into an option I have considered off-and-on, .. switching it to POP and/or IMAP.

And if the other browser(s) don't work, I can most likely check it on some newer computer. I just like my comfy-zone machine from 2012.

*solemn sighs* :\

Update:
I found that at least 4 alternative browsers could possibly work, Thorium, Midori, Pale Moon, and Maxthlon. Did research to check on them first of course.
So far, the protable version of Maxthlon seems ot be working well. :>
Probably will keep it to using just for GMail at least for the near future. This will allow me to continue watching the support and compatibility trends in the Opera and Vivaldi browsers.
