Like many others, I have used Firefox for a long, long time. Today (2/14/2023) is the last straw. I installed the latest upgrade and now my Bookmarks are all gone. When I say all gone, I mean "all gone." There is no backup, no previous dates, no nothing. I tried all the suggested by Firefox in the pages of the website. No help. And this is not an isolated instance. For the past several upgrades, many such issues have occurred with great frequency. This time, my layouts were gone, my toolbar icons were gone - not even in the "Customize" option. This is ridiculous and it is getting quite tiring. I'm not sure what the criteria is for developers, but it seems like some of the open source resources could be saboteurs even though that sounds far-fetched. For Mozilla, it boils down to this: either stop this problem so that it doesn't repeat or I (no doubt along with many others) will find it simple enough to relocate to another browser; maybe with fewer features but absolutely with fewer frustrations and difficulties. I would prefer that Mozilla fix the situation permanently, but I am not averse to seeking simplicity and performance. Joe Krsak
