Easiest/fastest way to close too many open tabs?

I hope this is the right place to post this. I’m not clear what the difference is between Browser Support and Desktop Support.

Description of the issue:
The down arrow that lists open tabs and closed tabs is limited and doesn’t show me everything. I tend to leave a tab open if I’m not finished with it or as a reminder to look at it later.
But I end up with duplicates since I can’t see everything I have open there (I just realized that).

How can this issue be reproduced?

  1. Open more tabs than the maximum shown in the down-arrow at the top.

Expected result:
Can’t see (or access?) all open tabs in order to close duplicates.

Brave Version( check About Brave):

Version 1.67.123 Chromium: 126.0.6478.126 (Official Build) (64-bit)

Additional Information:
I was using some tab groups at one point, but not at the moment or else they’re part of what I can’t see; possibly because there are so many tabs open (178 at this point), when I close Brave, sometimes it’s apparently not finished when I close my laptop lid and unplug it, or it gets shut down due to no battery charge (it gets hot, and since Windows 10 Pro now does things in the background even when in sleep/hibernation, I have to unplug it–of course then it’s used up the battery charge by the next morning. Then the next time I open Brave, it opens as one tab and I have to click four things to get all the tabs back. Edit: it didn’t lose battery this morning, but I still had to restore the tab history.
