I'd like an addon that auto-updates a bookmark as I browse.
I open a bookmark, browse a bit, and as I get to each new page (even if I end up at a completely different website) the original bookmark gets updated. Bonus points if it could even store the history, but not vital.
Imagine I bookmark [https://xkcd.com/2356/](https://xkcd.com/2356/) which is a webcomic. I might click this bookmark every few weeks, click to the next comic a few times, then close the tab. But my original bookmark is still the same. The addon I'd like would know this was a special bookmark when I opened it. As I clicked through to each new comic, the bookmark would update to each new page. Then after closing the tab, the bookmark would already be where I last was.
I wouldn't want this for every bookmark, only specific *special* ones.
