# FIREFOX
|

|
||||
Firefox has autoscroll of its own, switched off on Linux. There is no flag for
|
||||
it, only a setting: *general.autoScroll*. It goes into _user.js_ in every
|
||||
profile, as a marked block, and Firefox reads that file at every start. The
|
||||
same goes for everything built on Gecko: LibreWolf, Zen, Floorp, Waterfox and
|

Thunderbird.
|
||||
|
||||
Where the profiles are is read from the application's own _application.ini_,
|
||||
the way Firefox works it out: _~/.mozilla/firefox_, or
|
||||
_~/.config/mozilla/firefox_ for a new install of Firefox 147 or later. A Flatpak
|
||||
or a snap has the same inside its own folder. Every profile in _profiles.ini_
|
||||
is covered. The watcher looks at that file too, so a new profile is covered
|
||||
from its second start on.
|
||||
|
||||
A profile where the setting is already on, in Firefox's own settings or in
|
||||
_user.js_, is left alone and not recorded.
|
||||
|
||||
Firefox copies the setting into _prefs.js_, so *disable* takes it out of both
|
||||
files. A Firefox that is still open would write it back when it quits. So for
|
||||
that profile _user.js_ says *false* instead, and the next *disable* or
|
||||
*enable* clears it up.
