On my $WORK computer, I've been letting Ubuntu autoupdate Firefox
regularly. Starting with Firefox 86 I started to notice some issues.

In Firefox 86, at least as packaged for Ubuntu 18.04LTS, when running
with two or more windows, mouse clicks and scrolling events sometimes
go to the wrong window. This almost entirely happens just after
changing window focus between two Firefox windows, but I think I've
seen it with xterm to Firefox focus switch too. The second window
can be a private one or a regular one.

In Firefox 87, the window focus thing is not fixed, and I started to
run into other odd behavior. In particular while app.slack.com worked
for me initially, it eventually stopped working. The whole UI froze,
the reload button did nothing, and upon closing the tab and trying to
reload it in a new tab, I got a blank page.

I've downgraded to FF84 and everything works again, but the downgrade
was a painful process. Profiles are versioned now, and FF84 refuses to
touch a FF86 or FF87 profile, so I lost all my extensions, preferences,
and bookmarks in the downgrade.

Questions:

Has anyone else observed the window event problem in Firefox 86/87?

Has anyone else had Slack stop working with Firefox 86/87?

Are there automatic profile backups I can enable to make any future
downgrade need less painful? (If there are not, I can create one
myself, but I'd rather something more seamless.)

This is the most trouble a Firefox update has given me in a long time.
