New version in Opera/Chrome is still super slow.
Went through the recommended steps - of logging out, quitting browser, clearing it all out.
It worked for a bit, but then back to slow… The only thing that seems to work is not using the built-in extension and using the pop-out floater window. It’s still not as fast as it used to be, but faster than the built-in extension.
Fortunately, Firefox version is still on 1.55 - so no issues there.
