Changes:
The _content of the My filters_ pane is now considered untrusted by
default, and only uBO's own lists are now trusted by default.
It has been observed that too many people will readily copy-paste
filters from random sources. Copy-pasting filters which require trust
represents a security risk to users with no understanding of how the
filters work and their potential abuse.
Using a filter which requires trust in a filter list from an untrusted
source will cause the filter to be invalid, i.e. shown as an error.
A new advanced setting has been added to control which lists are
considered trustworthy: `trustedListPrefixes`, which is a space-
separated list of tokens. Examples of possible values:
- `ublock-`: trust only uBO lists, exclude everything else including
content of _My filters_ (default value)
- `ublock- user-`: trust uBO lists and content of _My filters_
- `-`: trust no list, essentially disabling all filters requiring
trust (admins or people who don't trust us may want to use this)
One can also decide to trust lists maintained elsewhere. For example,
for stock AdGuard lists add ` adguard-`. To trust stock EasyList lists,
add ` easylist-`.
To trust a specific regional stock list, look-up its token in
assets.json and add to `trustedListPrefixes`.
The matching is made with String.startsWith(), hence why `ublock-`
matches all uBO's own filter lists.
This also allows to trust imported lists, for example add
` https://filters.adtidy.org/extension/ublock/filters/` to trust all
non-stock AdGuard lists.
Add the complete URL of a given imported list to trust only that one
list.
URLs not starting with `https://` or `file:///` will be rejected,
i.e. `http://example.org` will be ignored.
Invalid URLs are rejected.
