I've given up and switched to Pale Moon. For me, Firefox reached its peak just before it switched from the classic download window and has been going downhill ever since. It's now rapidly going in the direction of too many formerly promising open-source projects - the core developers feeding back on each other until they go the way of the fashion industry - "This is what you need. Everything that came before is useless and must be discarded", repeating every so often.
