About this extension
Script Blocker Ultimate makes it easy to block Scripts and Requests.

Support Desktop and Android

Script Blocker Ultimate is designed to block Java Scripts and Requests.

Allow all:Through this method, Script Blocker Ultimate will allow all scripts to execute.
Block all:Through this method, Script Blocker Ultimate will block all scripts to execute. Be careful
Block all but whitelist:Through this method, Script Blocker Ultimate will block all scripts but whitelist.
Allow all but blacklist:Through this method, Script Blocker Ultimate will allow all scripts but blacklist.


While using blocking Java Scripts, you might encounter some irregular behavior in web pages which can be solved by white listing said web page.
I suggest to blacklist News sites that are full of ads and only their texts is important for us.

You can use '*' character in whitelisting and blacklisting domains (e.g., *.google.com).

Request Blocker
If you want to allow all scripts but block certain Java Scripts files, or even block requests to block images or videos,... you can use Request blocker.
Through this method you can easily block Advertising Networks or Analytic Scripts. (Google Analystic, Adsense are blocked by default, You can modify this feature in my addon options)


If you have any suggestions or found bugs/errors, please feel free to contact us on MojtabaDaneshi@Gmail.com
We look forward to your feedback.

Happy Blocking!
