Pocket won’t be missed. Self-hosted alternatives like Wallabag are better and private, so switched to it many years ago. Integration (and enabled by default, requiring about:config to disable) ensured I’d never use it out of principle.

Fakespot (the website) was genuinely useful to help ID scams on Amzn Marketplace, though I never used the extension. But I think that enshittified in recent years, so (in the style of Stephen King’s Misery) it’s probably for the best.

Related, the Keepa extension is useful as a price rigging detector, but I expect that will “number must go up!” soon enough, too…
