what is this used for?

[Bernhard Bauer, 2010/11/29 10:45:23]

It's used in the Clear Browsing Data dialog (the other prefs above are for the
other types of data).

[jochen (gone - plz use gerrit), 2010/11/24 19:03:07]

why do you need this pref? There's no code to change it, but you have code that
detects whether a suitable flash is installed?

[Bernhard Bauer, 2010/11/29 10:45:23]

PluginDataRemoverHelper updates this preference. It's instantiated by the pref
UI in order to disable checkboxes when no suitable plugin is installed.

Because the list of plugins could change at any time, and this check is
asynchronous, we can't keep the pref in sync all the time, so we just update the
enabled state when the options dialog is shown, and persist it for the next
time.
