Recently updated my 2012 MacBook Pro to macOS 10.15. After Firefox has been open for a while, it stops loading webpages. The title of the page loads, the browser window goes white and never displays anything; the page attempts to load continuously and navigation buttons don't respond. Other than that, Firefox operates and responds as though nothing's wrong. Meanwhile all other browsers can navigate the web just fine. Quitting Firefox (from the menu bar) causes the windows to close but an entry remains in "Force Quit" for an extended period. It can be forced closed from here, but doing so causes further attempts to open Firefox to have no windows appear; the only way to reopen Firefox appears to be to restart the whole computer. If allowed to close the rest of the way on its own- which can take up to 10 minutes- the crash dialog appears and Firefox can be restarted.
This has continued to happen despite repairing the drive, refreshing Firefox, removing and reinstalling Firefox, disabling hardware acceleration, running in safe mode, etc. There are no extensions installed and I have not synced my Firefox account.
I have 2 computers that show up as a single one in the synced tabs list, after cloning the profile from the one to the other

I cloned the my FF profile from a well set-up computer A to a new computer B following the instructions at https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles . I gave the profile on comp. B a new name.
The operation seems to have been successful, except for the tab syncing feature. I don't see the tabs from both A and B in the synced tabs dialog. Instead, I see tabs open on the one or the other computer, or a combination thereof.
If I had to guess I would assume that each profile has a unique ID, invisible to the user but determinant for distinquishing devices (profiles).
If accurate: how to change that Id?
