User JavaScript and CSS

Great job! Since today other js files are no longer included. Could you please check this?

Need to reload the website to update css injection. Not helpful

Using your extension has been great, however I discovered a problem in CSS when special characters are being used as selector. I tried to escape the characters by putting a slash i.e. "\" but it doesn't seem to work. Class name is w-1/3 h-full hidden lg:block .w-1\/3 h-full hidden lg\:block { display: none; } Any clue?

I'm A Happy User!

I love the design of this extension, I thought at first that it is a userscript manager and got excited but figured out that it is more intended to write userscripts and userstyles and get them applied to specific domain names, but it is not a alternative to TamperMonkey, ViolentMonkey and Please donate to Dmitry Novikov and encourage him to work on a new Userscripts Manager.

On Chrome 136, enabling Developer Mode in the extensions manager allows the ‘User JavaScript and CSS’ extension to apply CSS as expected, but JavaScript fails to run.

Great app, but newest chrome version just broke this because of changes google made. Looking forward to updates!

Really useful and cool extension!

Awesome, it works great! Thank you <3

Why do I have to reload the page every time I visit it for the CSS to load?

Beautiful, free, powerful, SASS support, the best of it's kind!

I just love it! Thanks for the awesome extension in terms of UX and functionality!

Awesome extension! Love the combo of JS and CSS/SCSS both in one + the nice dark themes. 👌 Just one question out of curiosity: Is there any performance impact (positive or negative) when enabling the "Isolated Environment", maybe due to some overhead or similar?

You can create multiple JS and CSS scripts for each website and name them, toggling them on/off as needed. Text editor is color-coded and easy to work with. Super useful for anyone who knows a little code and wants to customize their browsing experience.

Great extension, thank you, but there is a moment that can be improved. Please, add possibility to load js/css from files, to work inside your favorite IDE and after saving it to load them in extension.

Genuinely phenomenal. Worked just like I wanted it to, right out of the box. Great stuff.

Used for CSS. Works perfectly. Thanks!

this extension does what it says on the can. it just works. great. maybe missing a way to share scripts/css, but i get it, security and all.

Absolutely the best extension I've been looking for. Finally I can hide all those useless things I never want to see. Thank you for this perfect extension

Perfect. The auto !important is a very useful button.

Splendid extension. I use it to test js injection for work to digest and convert tables into interactable ChartJS canvas elements, or for personal handy things like spitting out drive distances on an auctions site so I can easily see how far each one is- and it is absolutely perfect.

Its a great extension for online sites. However as a developer, the extension seems to be causing AntiForgery token errors on localhost with the error '__RequestVerificationToken' is not present. This even happens if I don't have a rule on my localhost site. The moment I disable the extension, it all works again.

Works! Működik! 🙏

Brilliant extension :)

I would like to migrate my JS & CSS settings from Chrome to Vivaldi. Do I have to copy and paste them one by one?

Great extension. Only thing that's missing is the option for a vertical split between the editors for vertical monitor setups. Would be perfect with that added.

Great extension but not too much customization. Suggestion for developer: - add possibility to share your piece of code with others (ability to install my code for other users); - add possibility to create custom snippets in editor (for now autocomplete works not as well as I want), so this feature will fix it; - add One Dark Theme, idk why this theme is not added, is the most popular theme in VS Code, Jetbrains editors... - can't choose editor font family But in general it's ok, good job!

Very good and more stable than Tamperamonkey/Violentmonkey. It also works with Edge canary on Android, but unfortunately the icons such as “run on startup” are hidden in the browser bar.

Does one thing and does it right. This is the code injection extension you're looking for.

Amazing Extension

Very good extension, respect!

weird how when i save it jumbles up all my code :(

Superb. Works really well, and a great UI.

Look very good with nice clean interface!

Great extension, I love that I can find the same features and shortcuts as in VS Code, it's really a great experience ^^

Holy Cow...this is a good one

wow!

I love that it allows a quick toggle, so I'm not forced to have a specific rule on all the time, but I can turn it on, only when I need it! ❤️

Super!!!

I love it very much but I have a problem it works on chrome perfectly and also on android Kiwi Browser and but now it doesn't work on android Kiwi Browser I hope you to solve this problem please

nice

"Could you add a feature that allows switching between JS or CSS editing panels via a tab? Also, the left sidebar is too large, making the entire code editing area feel cramped and somewhat overwhelming."

Perfectly worked for my requirements. Thanks. Much appreciated.

Works most of the time but sometimes it caches the old code and even after multiple changes, they don't get reflected on the site.

This is one of my most frequently used tools. Love the purpose, usability and the constant, seamless improvement. Kudos to the developer: you are part of my internet, my work and my workflows, <3.

Very useful

Just started using it. Very nice. One thing that would make it more perfect is if the CSS updated in open tabs upon save. The Programmatic Injection implies that it will load edits without reloading open tabs, but my experience is that the styles either do not get injected at all, or still require the tab to be refreshed.

Great tool - allowed me to customoze and improve some manual work on website that is not mine :)
