Run Javascript is a Chrome Extension that allows you to run custom Javascript each time you visit a website.
It is particularly useful to web developers and people who like to tamper with websites they frequent by injecting additional javascript to manipulate the DOM.
If you don’t always have it, you can get it here:

Using “Run Javascript”
You are initially presented with a window if you click the Run Javascript icon.
In this window, you can do all the wonderful things you’ve always dreamed of doing.
Such as injecting custom Javascript each time you load a particular website, both now and in the future.
Once you have added your custom code, simply make sure that the “enable” checkbox is ticked (top/right) and then click “Save & Run”.
That’s it! Now every time you visit this particular website again, this code will automatically run.
Useful for testing various scripts more easily than the ones that open in their own tab pages.
A few questions in case anyone knows the answers I’d appreciate your time:
Thanks, guys!
I can’t save code with more than 500 lines
it is really not working all the alert and var will shut this app down
. . . well, Alert does not work. . .
Do ao.ms have any versions of “Run JavaScript” on iPhone?
I love this. Great for setting hotmail.com email adverts to 0px width or height with a setInterval function.
I think the ok.ru website is intact.
Not working for long scripts
Receive ‘Unchecked runtime.lastError: Could not establish connection. Receiving end does not exist.’ each load
not crucial but annoying
Can, You, please, fix it?
Ah ha. so it’s this extension causing it. I wasn’t able to track which extension was the cause, only that it was an extension. Would be nice to have a fix
Hello, where is restoring saved js code? Thank you.
did some debugging on the code wont save issue. its when the code is greater than 8000 char
What point in a page’s load is the Run JavaScript extension triggered to run? I have a page where it occasionally doesn’t work. I’m trying to run a single-line JS that enables auto-suggest on an input field:
$('input[data-test="username"]').attr('autocomplete','yes');Sometimes it doesn’t work, but it always works when I run it manually. The page is https://console.us2.crashplan.com/
It runs right after page load, however, you can control this by doing one of the following:
$(function() { $('input[data-test="username"]').attr('autocomplete','yes'); })or:
setTimeout(function() { $('input[data-test="username"]').attr('autocomplete','yes'); }, 3000);where do I get my custom code for a site from?
The script stops saving at around 220 lines of code.
8000 char limit?
From incremental testing, appears to be 8130 character max if on a single line.
Each additional line on Windows reduces it by two characters. Could be using /r/n on Windows.
I just get it to pull in JavaScript saved on my dev box:
const scriptTag = document.createElement('script'); scriptTag.src = "https://example.com/path/to/inject.js"; document.head.appendChild(scriptTag);How can I added a PHP script to run my Macros Chrome Extension ? thx u
Thanks. This is so interesting.
The extension is awesome. My question is how to save the script. It worked, but now I have added some more code and it does not save. After save and execute the window does not close, and when I hide it manually and open, my changes are missing

Where are the js files stored locally… I created one a while back for a locally saved html file and I don’t have access to that currently.
Did you find out where they are saved?

Hi Justin,
Are you getting an error with this code, or what is the specific problem you are encountering?

you can add a logic check it:
