The update apparently affected different computers and browsers in different ways. For some it improved; for others it got worse. Exactly the way it always works.
For the first time in months I had a very inconsistent meter this morning but I'll reserve judgement on what happened until after another few rounds. If I find that things have indeed deteriorated using this browser, I'll be trying the others available to me to see if any are better. If they are, great. If they aren't, not a big deal. I'll still be playing games with friends and having some social laughs and chats.
If the meter becomes unbearable, we'll go somewhere else where we can play some other game and chat. This game is not the only form of entertainment on the internet with chat capability and forums.
