After a while (if you visit many-many pages) the Tor browser starts
misbehaving - can't save files, difficulties with loading/displaying
pages, and eventually all fonts (i.e., all text) suddenly disappears from
pages and menus as well (except for a leading underscore _). You get
errors on console by some shm_*() function (cannot recall name correctly)
complaining about too many open files and lsof indeed shows bazillion
files for the Tor firefox in directory tor-browser_en-
US/Data/Browser/profile.default/thumbnails/ mostly in deleted status.
Clearly unexpected behavior.
One workaround is to sigterm the browser with kill + pid and when you
restart recover all tabs etc. Firefox also has docs on disabling thumbnail
collection or usage altogether which should work (have not tried it). I
decided to replace the thumbnails directory with an immutable file and
have not seen the bug since.
Saw this with the latest 3.6.2 but also with earlier ones.
