The scriptlet will trap calls to JSON.parse, and
if the result of the parsing is an Object, it
will remove specified properties from the result
before returning to the caller.
Usage:
##+js(json-prune, arg1, [arg2])
Where:
- arg1: a list of space-separated properties to remove
- arg2: optional, a list of space-separated properties
which must be all present for the pruning to
occur
Example:
##+js(json-prune, enabled, adpath config)
A property in a list of properties can be a chain
of properties, example: adpath.url.first

Messages from unprivileged ports (i.e. from content scripts)
are no longer relayed to message handlers which are to be
strictly used to execute privileged code.
The last remaining case of unprivileged messages which
should be converted into a privileged ones will be taken
care of when the following issue is fixed:

This also apply to setInterval-if. Thus to defuse
calls to setTimeout(fn, 1000), the filter could be:
##+js(stif, , !1000)
Meaning "allow setTimeout if the delay is not 1000".

A bidi-trie can't store strings longer than 255 characters
because the string segment lengths are encoded into a single
byte. This commit ensures only strings smaller than
256 characters are stored in the bidi-tries.
Plain filters can be any length, while the bidi-trie was
assuming max length of 256. The origin of this error
is from when the bidi-trie code was originally imported
from the hntrie code as start to develop bidi-trie.
The erroneous code could cause issue when the following
conditions were met:
- Plain filter longer than 256 characters
- Free space in bidi-trie's character buffer was less
than 256 bytes
Likely a rare occurrence, but some filter lists do contains
long plain filters, for example:

Usage is similar to that of raf-if introduced in
commit 6831967f5f.
The two new scriptlets are meant to replace:
- setTimeout-defuser
- setTimeout-logger
- setInterval-defuser
- setInterval-logger
setTimeout-logger and setInterval-logger have been
removed, since they are not to be used in production.
To log setTimeout and setInterval usage, respectively
(using aliases):
- ##+js(stif)
- ##+js(siif)
To defuse setTimeout unconditionally:
- ##+js(stif, !)
Usage of setTimeout-defuser and setInterval-defuser
is deprecated and will be removed in some future when
they are no longer in use.
Keep in mind that the new scriptlets function on a
whitelist basis, whereas the deprecated ones
function on a blacklist basis. Prefixing the needle
with `!` allow to use the new scriptlets on a
blacklist basis.
