I don't know about you, but my mobile browser hasn't display the number of open tabs in years because it displays :D (a smiley) if you exceed 99 tabs.

Half of these tabs are work-related, often to-do items, and the other half is things I have yet to read or that I don't want to forget about but was too lazy to create a bookmark. (FWIW, there is no way to store all tabs as bookmarks, unlike in the desktop version of the browser.)

One time, after a crash or accidentally closing all tabs and then restoring them, a toast message showed the tab count and it was around 750 back then. That was 2-3 years ago and I have left more tabs open since then than closed. I'm definitely a hoarder.
