Some sites I just want to visit regularly, but I want to do so with the extra privacy protections afforded by the Tor and/or Mullvad browsers. I hesitate to add bookmarks to them, though, for fear of “breaking” that extra protection (so I just save them elsewhere and copy/paste the links in).
Does adding bookmarks to a web browser make it more fingerprintable or cause other issues?
This is good general advice for settings that websites might be able to use for fingerprinting. But bookmarks are completely unknown to the sites you visit. At worst, websites will be able to measure the difference between window and document height to determine if the bookmarks toolbar is open, so whether it’s enabled or disabled by default I’d leave it that way. The bookmarks themselves should be no problem for any reason I can think of, though.
