Firefox is mostly non-functional after wake from suspend
I have my Linux PC set to sleep (i.e. suspend) after a couple hours of inactivity. This works as expected—except for Firefox. Recently, it seems every time I wake the PC from suspend, Firefox is in a “bad state”: there are many pages that simply won’t load. The most common case is I click on a link to go to a new page, and the current page will clear, and the next page will either not load at all (i.e. nothing but a blank screen), or only a very small portion of the page will load.
It is resolved if I kill Firefox and restart it. But this is very annoying, since I deliberately keep over a dozen tabs open.
I thought maybe this was some bug, but it has persisted for several weeks now, across multiple Firefox version upgrades (currently on version 79.0).
The other thing that may be relevant - I recently changed my home directory to be on an auto-mounted NFS share (rather than on the local disk of the PC). I don’t recall if this errant Firefox behavior started at the exact time as making this home directory change or not.
Thank you for any help or advice!
