-However this led to the often-repeated myth that the reason µBlock was efficient memory- and CPU-wise was because it did not support regex-based filters, a completely nonsensical assertion, given that there is a grand total of only 15 such filters in all of _EasyList_ (at time of writing) out of tens of thousands.

 It is because of this myth that I finally decided to support regex-based filters with version 0.8.6.0:

 An efficient regex-based filter is one which does not need to be evaluated.

 1. `domain=`: The regular expression won't be executed if the hostname of a request does not match the hostnames declared in the `domain` filter option
 1. `third-party`: the regular expression won't be executed if the request does not fulfill the `third-party` option (or it's complement `~third-party`)

     /http:.*(?:\+|\@|\=|\;|\_|\-|\!|\?|\&|\%|\#|\^|\:).*\/\//$script,third-party,domain=allenbwest.com
 
 This filter contains all the filter options which makes it very unlikely that the regular expression will have to be executed. The regular expression will execute **only** if the request is of type `script`, originates from `allenbwest.com`, and is 3rd-party to `allenbwest.com`.
 
-If this sounds like basic common sense, it's because it is. However I've seen other big-name blockers out there execute all regex-based filters unconditionally for every request.
