Firefox fails to clear local storage
Status in firefox package in Ubuntu:
I noticed that Firefox is keeping site-specific information even after
using the 'Clear Recent History' option. For example, with a new
firefox profile (e.g. start a guest session) go to www.youtube.com and
view some video, then look in the location:
You should see a subdirectory named "https+++www.youtube.com". Now
clear all history using the menu option History -> Clear Recent
History... by selecting "everything" and ticking all boxes.
Result should be no sign of having visited youtube. However the site-
specific storage directory still exists which is a significant laps of
privacy. It seems not to happen in a private tab, but that is not an
excuse for failing to clear on requested.
$ lsb_release -a
