Oh, wow, Hangouts and Meet are working in Firefox now? I've been keeping Chrome running just for that for a couple of years, will be glad to stop having to do that.
Meet didn't even work in Chrome on Ubuntu 16.04 last time I checked. A customer of mine that went all Google talked about going back to Skype, which fixed most problems in the last months (with the obvious exception of the uselessly sparse layout.)
I've found that "work" in this case is still even a stretch. With it being the only application that I have open, with one tab on Firefox, these sites (but especially Inbox) cause my zBook to sound like it's mining Bitcoin or running SETI analysis.
What is not working? I have been using google flights to book trips for months without issues now. The only google services I've had some trouble with firefox are hangouts, and even that is fixed.
Great response from Alex Russell, but it's clear that the sentiments of the Chrome team aren't translating into policy elsewhere in Google, or we wouldn't be dealing with something like this every few months.
