Following the instructions at How to run multiple Tor browsers with different IPs? I now have multiple folders that can host a different Tor Browser instance.

How can I update all of them on Ubuntu without downloading ~50 MB for each one?
(by updating via "Help" --> "About Tor Browser")

(I would like to keep the unique bookmarks and settings for each one. Therefore, I cannot simply copy the steps I took in the above link)

You could export settings and bookmarks by copying the files from somewhere in

Tor Browser/Browser/TorBrowser/Data/Browser/profile.default


Download the .mar file and learn to use mar-tools to manually apply the update for each copy of your browser.
