Hello everyone, first time posting on this subreddit.

So currently I have over 200,000 bookmarks on my Windows laptop split across these browsers - Chrome, Brave, Edge, Firefox, Opera, Vivaldi and Chrome Beta (Chrome Dev seems to be quite unstable).

Due to privacy and security reasons, I DON’T want to use ANY online/cloud service, and I use all browsers on my laptop SIGNED OUT so there is NO online/cloud syncing, NO multiple profiles, and ALL the bookmarks are stored LOCALLY on the laptop’s hard drive. I also keep exporting them from time-to-time in HTML formats as backups.

I have NO duplicates or waste bookmarks, they are well organized into dozens of different folders and it has been my habit to collect various links, websites and URLs since nearly a decade now.

Genuinely curious about whether or not this process can scale to potentially MILLIONS of bookmarks in the future, because its part of my habit to store bookmarks while browsing the web.
