Instead of “exporting” them, I would recommend you bookmark them and from there, your bookmarks can be exported and imported into other browsers/versions of Brave. You can do this quickly by:
- Tapping the tabs box
- Then tap the three dots icon on the bottom right and select
Select tabs - Tap the 3 dots icon on the top right, tap
Select all - Tap 3 dots icon again and then
Bookmark tabs
