When typing in the search bar, there are a bunch of prefixes you can use to narrow what Firefox is filtering on. Type one of these characters and then a space to get more precise auto-complete suggestions:
^: search your history%: search open tabs (includes mobile tabs!)*: search your bookmarks+: search pages you've tagged (you can do this when you bookmark something, i never have but it's aspirational #aspirationalcomputing)There’s a bit you can set on a directory called the sticky bit. It makes it so a directory is “append-only”. That is, only the user who owns the file (or directory) can remove or move the file.
The man page (featured below) doesn’t make it clear, but a user also can’t edit a file owned by another user in the sticky place.
sticky — sticky text and append-only directories
A special file mode, called the sticky bit (mode S_ISVTX), is used to indicate
special treatment for directories. It is ignored for regular files. See chmod(2)
or the file /sys/stat.h/ for an explanation of file modes.
STICKY DIRECTORIES
A directory whose ‘sticky bit’ is set becomes an append-only directory, or, more
accurately, a directory in which the deletion of files is restricted. A file in
a sticky directory may only be removed or renamed by a user if the user has
write permission for the directory and the user is the owner of the file, the
owner of the directory, or the super-user. This feature is usefully applied to
directories such as /tmp which must be publicly writable but should deny users
the license to arbitrarily delete or rename each others’ files.
Any user may create a sticky directory. See chmod(1) for details about modifying
file modes.
HISTORY
A sticky command appeared in Version 32V AT&T UNIX.
BUGS
Neither open(2) nor mkdir(2) will create a file with the sticky bit set.
