I tried to install Facebook Container a Mozilla add-on for Firefox, from add-ons menu, or from this page,
but i have the message “This add-on is not available on your platform.”
I don’t understand why. Some other add-ons had been found and installed correctly (https everywhere, ublock, privacy badger)
Is /e/ not well recognized as an android, or is it a Firefox add-on service error ?
Its a Firefox for mobile thing, that extension is not available for FF on mobile unfortunately. I tried on a non /e/ device also, same result. And I haven’t come across any alternative for FF mobile yet.
