ReqBlock

A simple request blocker.

Block requests with simple url patterns. The blacklist can be specified on the options page. The configuration is a simple block of text to make exporting and importing simple (copy & paste). While the options page is open, the request can be collected so the blacklist can be updated accordingly. A request url matches a line, if the spaces inside the line can be filled to get an exact substring of the url. If a request url matches any line, it is blocked. Empty lines and lines where the first non-whitespace character is the # are ignored, and provide a way to comment and group your rules. The tidy button removes leading and trailing whitespace from every line, and sorts rules inside groups separated by comments and empty lines. The configurations is backed up by sync storage if availlable, otherwise the extension falls back to local storage. Also works without storage, but configuration changes are lost on browser restart.
