Firefox 63.0.2/63.0.3 unstable on Mate desktop

Since the last couple of updates Firefox has been completely unstable on my machine running the Mate desktop.  After some period of time (anywhere from 5 minutes to an hour) pages stop loading and the application stops responding to keyboard/mouse.  I do keep a lot of tabs/windows open, but the number is roughly constant, and I don't recall having had this problem before.  I tried refreshing Firefox (which recreates all the databases from scratch) and removed all Add-ons (I only had 2), but the problem persists.  I have plenty of RAM (32G), so don't think I'm running out of memory.  When I am able to quit the application after it becomes unstable and before I lose keyboard/mouse focus, the associated processes hang around for several minutes (e.g.

and don't respond to pkill or kill -9.  Seems like some kind of newly introduced GTK3/Firefox bug.  Oddly enough, when this happens Thunderbird becomes unresponsive as well.  In fact, at first I thought this was a new Thunderbird bug and posted it as such before realizing that Thunderbird reverts to normal behavior as soon as all the Firefox processes have finally died.  Not sure I understand that one at all.

Re: Firefox 63.0.2/63.0.3 unstable on Mate desktop

Some further experimentation revealed that Firefox 63.0.3 is completely stable on my system as long as a don't run Thunderbird 60.0.3 at the same time.  Thunderbird is stable as long as I don't start Firefox while Thunderbird is running.  It's just when I have them both open that everything starts to go haywire after sometimes barely 5-10 minutes of use.

Is this version number a typo?
