Google removes this extension

This was one of my favorite extensions; thank you for developing it. I would be very happy if you consider making it open-source. Best regards.

Dark Mode?

Hello, I would like the extension to have Dark Mode, because my views burn a little when editing code. Thank you very much.

Website unresponsive

Hi! Thank you for this great tool. I needs some help. Can't add JS to this website. Random page: https://torrentz2.nz/search?q=Fire+of+Love The code I've tried: document.addEventListener('DOMContentLoaded', function() { try { // Select all the elements with the class 'dl dt a' let elements = document.querySelectorAll('dl dt a'); if (elements.length === 0) { throw new Error("No elements found with the selector 'dl dt a'."); } // Iterate over the elements for (let i = 0; i < elements.length; i++) { // Add the 'full-hd' class elements[i].classList.add('full-hd'); } } catch (error) { console.error('An error occurred:', error); } });

CSS is wrongly inserted as JS, causing SyntaxError

Hello, I am a long time user of this extension, so first of all thanks for your work.
I know there are other extensions more specific for CSS, but I noticed that yours could also deal with that, so I just decided to give it a quick try but I found a problem: even after selecting CSS from the extension drop down menu and saving the code as that, it will end up being added as JS, causing this error in the JS console:

SyntaxError:
Unexpected token '.' (at data:text/javascript;base64,Lnl0cC1wYXVzZS1vdmVybGF5LWNvbnRhaW5lciwgLnl0cC1wYXVzZS1vdmVybGF5IHsgCiAgZGlzcGxheTogbm9uZSFpbXBvcnRhbnQKfQ==:1:1)

I hope you can fix it soon, if you need any other info from me just let me know.

extension breaks steam checkout

when the extension is enabled at all (doesn't matter if I "disable for this domain") steam's website starts to act up. For example, the checkout flow stops working entirely when trying to buy a game. Perhaps "disabling for this domain" could be made even more strict

Automatically Start on certain Pages

Hi! Great Extension!

Is there a way to automatically start the extension, without having to reload the page after pressing "Save"?
