I should probably figure out some way to keep my bookmarks. I'm using 3 browsers (FF, Tor Browser, Bromite - soon to be replaced).
I don't want online sync or accounts.
Just a way to keep it in one place with export/import/backup.
ColorNote can receive bookmarks through sharing including titles, at least one by one. But another thing is I'd like to replace CN with something foss, not rely on it even more.
Did you mean “offline” as in not online (which makes little sense for a browser), or more like “not tied to a specific service that may hold your data hostage or infringe upon your privacy”?
If the latter, then I've found that a simple HTML file with manually added entries works great. I've set it as the home page in all my browsers. I retain full control over content and layout as well.)
