This commit ensures FLoC is opt-in. The generic filter
`*##+js(no-floc)` in "uBlock filters -- Privacy" ensures
the feature is disabled when using default settings/lists.
Users can opt-in to FLoC by adding a generic exception
filter to their custom filters, `#@#+js(no-floc)`; or they
can opt-in only for a specific set of websites through a
more specific exception filter:
example.com,shopping.example#@#+js(no-floc)
The syntax to remove response header is a special case
of HTML filtering, whereas the response headers are
targeted, rather than the response body:
example.com##^responseheader(header-name)
Where `header-name` is the name of the header to
remove, and must always be lowercase.
The removal of response headers can only be applied to
document resources, i.e. main- or sub-frames.
Only a limited set of headers can be targeted for
removal:
location
refresh
report-to
set-cookie
This limitation is to ensure that uBO never lowers the
security profile of web pages, i.e. we wouldn't want to
remove `content-security-policy`.
Given that the header removal occurs at onHeaderReceived
time, this new ability works for all browsers.
The motivation for this new filtering ability is instance
of website using a `refresh` header to redirect a visitor
to an undesirable destination after a few seconds.
Too likely to cause breakage. It was originally added without
having been really evaluated. As per feedback, it's too likely
to cause breakage.
The list is seemingly used to evaluate filters, which are moved
to EasyPrivacy once they are deemed valid and useful.

Prior to this commit, the ability to enable/disable the
uncloaking of canonical names was only available to advanced
users. This commit make it so that the setting can be
toggled from the _Settings_ pane.
The setting is enabled by default. The documentation should
be clear that the setting should not be disabled unless it
actually solves serious network issues, for example:
https://bugzilla.mozilla.org/show_bug.cgi?id=1694404
Also, as a result, the advanced setting `cnameUncloak` is no
longer available from within the advanced settings editor.
