Blocks Coin-Miners from Websites before and after they load.

v1.0.1: Added Background content blocker which scans Javascript requests for CoinMiners and cancels the requests. The background blocker tells the content blocker to remove the script from the webpage. This blocks sites self-hosted miners and proxy-miners.

v1.0.2: Added Settings page to allow users to add white-listed URL patterns.. For example: (.?)google(.?) would allow all urls that contain "google" to not be scanned. These rules use "regex"/"regular expression" patterns. Also added new patterns to block Base64 encoded Javascript miners which was a workaround to this plugin. Now this blocks everything again =]

v1.0.3: Fixed bug in Firefox and Chrome which causes webRequest.onBeforeRequest to NOT cancel the download of bad files. To fix it, I made scanning synchronous instead of asynchronous (a bit slower, but not noticeable). Fixes issue: https://github.com/Brandon-T/Coin-Blocker/issues/1

v1.0.4: Fixed bug in the code which caused some white-listed sites to be scanned and blocked still. Added debugging code to print to the developer's console exactly what was blocked and what was allowed.

User reviews

Категорически не рекомендую. Не устанавливайте это расширение, если не хотите чтобы важные функции сайтов вдруг сломались. В моем случае это были: чат твича, кнопка поделиться вк, целый сайт дискорда и challonge.

Maybe this incidentally does what it purports to do, but what it mostly does is clobber innocuous JavaScript applets, even at Wikipedia. This is like burning your house down to kill some roaches. In 5 minutes of use I found a dozen of my regular websites broken, and I can see the scripts being nuked are not stealing resources from me to do cryptocurrency mining for someone else. They're harmless stuff. This extension is not.
