There are two kind of these regex currently used inside easylist:

/^https?:\/\/.*powvideo\.net\/.*(\?|&|\$|=|&|!)/$script,subdocument /^https?:\/\/.*.streamplay\.biz\/.*(\?|&|\$|=|&|!)/$script,subdocument

Could be them fixed in order to avoid java.util.regex.PatternSyntaxException ?

While I have less than zero experience with Privacy Browser, I presume that changing (\?|&|\$|=|&|!) into ([?&$=!]) or even simply [?&$=!] would be worth for the EasyList team to try out.

[sorenstoutner]

I am the developer of Privacy Browser. The problem is caused because the parser used by Privacy Browser considers any $ to mark the end of the URL and the beginning of the EasyList types. These two newly-added entries both contain two $. This causes the parser to truncate the regular expression, resulting in a regular expression pattern compile error.

Looking at the regular expression, I have a hard time imagining that any of the URLs you are trying to block actually contain a $. It looks more like someone copied some syntax meant to catch all strings, and ended up including it here even though the $ is not needed.

Should be fixed now.
