Managing my bookmarks across them it's pretty hard!
Do you know any sync tool that can handle bookmarks from those three browsers and make them synchronized?
Delicious was exactly what I wanted, except it was very annoying for me, as I had to think about keeping links private.
Pinboard is exactly what I want, as I don't have to struggle to keep my bookmarks private.
It costs about $10 for however long they stay in business. You can pay a yearly fee (I forget how much), which gives them revenue (please stay in business!), and return they archive the contents of everything you mark.
It's not a browser synchronizer, because the marks are kept on their server.
However, every bookmark can be tagged, with one or more tags. Any tag, or any combination of tags, has an associated RSS feed. Firefox has Live Bookmarks, which look like bookmarks but it's an RSS reader. So if I tag a bookmark at work, it's available at home because I've set up a live bookmark to view that RSS feed. It's brilliant.
Which isn't exactly what you were asking for, but if you can view these RSS feeds some way in chrome and safari (I have no idea), then you get sort of what you're wanting, and independent of a particular browser.
