I guess everyone is doing this already? 😅
Yesterday I finally changed my browser from Dia to Comet. I was dreading the 226 open tabs "loss" - because of course! So I asked my agent to read and re-open them all in Comet. And since we were at it, I also wanted it to pick up all my X bookmarks and all Dia bookmarks, read and reorganize them. It just did it. Over 1,500, nice and tidy.
To note, it was using its own browser, not X API. ✅
