After I spend a few hours for it I can say: It works :-) And it works for .php and not for .html unfortunately

I'm updating my review (January 2025) to say that it works great with VS Code. For advanced PHP development, you need to launch your server (like WampServer, XAMPP, etc.) and also start the Live Server from VS Code.

In the extension's window, fill the first field with your local project URL. The second field is the URL of Live Server, which uses port 5500 by default.

This extension is a must-have, thx!

Excellent extension! Thank you.

Great addons but it seems not working on Firefox Quantum yet

Talk about a little time saver, this is it! Saves me the hassle of having to go to the command line and launch a live server for my web pages OR starting up XAMPP as a server. You even added PHP, great job

Awesome add-on, im in love with it!
I'm using it with PHP.

btw: the chrome-extension is also working :)
(development mode)

thanks to your hard work for developers
