Unable to migrate or restore OneTab and its data

None of the available migration or restore methods are capable of preserving OneTab data. In every case I have tried, OneTab is missing from the add-ons in my new installation or profile. The only approach which achieved anything at all was to replace the entire .mozilla director under Ubuntu, but even this only displayed the OneTab page and its data on the first invocation of Firefox. Since the add-on was not present, the data was gone at the second invocation. However, repeating this process at least allowed me to export the OneTab data from *one* profile on the first invocation. Unfortunately, this method is completely useless under Windows, as are the recommended approaches of using Firefox sync (with sync turned on for add-ons) or replacing the contents of a newly created profile with the contents of an old or saved one. How can I properly backup and restore or migrate a Firefox installation, *including* my OneTab installation and data?

Re-Installing Mozilla - Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window.

I shut down my PC without closing the Firefox brower tabs and I started getting this message the next time I re-booted and tried to start Firefox. --- "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." ---

I read thru the different support forums and tried various answers/suggestions - no luck. Bottom line, I have uninstalled the browser, deleted all the old Mozilla folders from the machine and downloaded the .exe to try to re-install the browser. However, the installation crashes at about 70% completion and I still get the message listed above. I am running on Windows 10 and the PC is up to date with all patches.

I would appreciate if anyone can help me figure this issue out.

I have a Mac system that has been on OS X 10.11.6 for a long time, and was switched to the ESR channel when the release channel no longer supported this version. I have finally been able to update that system to something later (Mojave, 10.14.6) and want to restore Firefox to the release channel. How do I do this and preserve all of the Firefox settings, history, etc.? Won't installing a fresh copy of Firefox wipe all that out? Thanks for any help you can provide.
