Description from store Run custom Javascript, each time you visit a website. This extension is particularly useful to web developers and people who like to tamper with websites they frequent by injecting additional javascript to manipulate the DOM. Add in any javascript you like and it will automatically be executed everytime you visit the website in the future. jQuery 3.3.1 is pre-loaded, so you can use all the $ magic immediately!

Latest reviews (2019-09-24) Oguz Onat: I don't usually write reviews for extensions but man, this is nice. I wish it had a way of displaying / exporting the code I'm writing for the pages I visit but even without that feature, it's lightweight and pretty straightforward. (2019-08-21) Syed Arif Iqbal: This is exactly what i needed. thank you for great extension. (2019-04-16) jack donsen: 挺方便的，如果窗口能固定就更好了 (2018-10-29) Rishav Rungta: This is one of the best ones out there. Thanks for loading JQuery :) Although it could be better if the address could be more interactive. Example: Instead of run on www.google.com we could do www.google.com/foo/foo optionally (2018-08-17) Statvoo Support: Really useful to be able to always have the same custom javascript executed on a domain. Able to get rid of nag banners and popups really well!
