I presume you have some way to mitigate the "time bomb" which I understand to have been built into the Flash plugin for some unspecified number of versions now, such that the plugin will itself stop working on the deadline date (which IIRC was January 12th, 2021)? > Here are the approaches we've tried so far: > > 1.

At first glance, this looks as if one of the "auto-fullscreen" addons might help. There is at least one Firefox extension out there [1] which essentially just takes the browser fullscreen at launch time, in exactly the same way as if the user had pressed F11 after launch. I recall there having been multiple such extensions, with different behavior sets; I tried a few of them and settled on one to solve a type of kiosk-mode requirement I encountered a while back, although that was on an earlier Firefox version and I can't confirm just off whether it still works on ESR78. I don't remember which extension it was for certain, and I won't be back at my workplace to be able to check for another week. If my memory serves me correctly, this can still be reversed post-launch by pressing F11 again, although I can't testify to that for certain. Whether that would be a problem for your case I don't know.
