Run custom Javascript, each time you visit a website

Image from store Run Javascript
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!

  • (2021-11-28) Crowtower: I was going to write my own extension just to rewrite the browser url if certain conditions were met. This little extension saved me the hassle! It works perfectly!. My only feedback would be that the extension icon is a bit ugly haha. Thanks for making this!
  • (2021-09-16) nomadev: Very helpful!
  • (2021-09-14) Kamil R: working as intended. But there should be some feature to make an cloud backup. Would be also good if you add some prefiled event listeners, like run code when page loads, when dom ready etc, because sometimes you have to wait with code until content appears
  • (2021-08-17) ATPoker133 ATPoker133: nice
  • (2021-08-13) Asef Hosseini: pinned icon could be better (transparent) and it gives me this error on console when developing on localhost: `Unchecked runtime.lastError: Could not establish connection. Receiving end does not exist.`
  • (2021-08-11) mostafa abedi: It is a useful tool But I do not know where the data is stored and will not be lost
  • (2021-04-05) d4jk4 aloza: Cool, 10 stars
  • (2021-02-15) Martin Kadlec: This is what I've been looking for. I have few questions though: a) When does the code run? Before anything else? DOMContentLoader? onload? b) If I don't use jQuery is it going to be used on the page anyway?
  • (2021-01-28) Scott Gartner: Does not work in Chrome v. 87.0.4280.141 (Official Build) (64-bit) on any site I tested it (including the author's website).
  • (2020-12-07) Tân Lê: Tks, It's very good
  • (2020-09-24) Jacob Holz: It does exactly what I wanted and more. Thank you for not making me make this from scratch
  • (2020-03-28) Dylan Rex: does it work for roblox?
  • (2020-01-31) Vladislav Velichko: Very good. Please add hotkey for running my script
  • (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!
