does not work for a long time

Cannot pin onto the toolbar. The shortcut key is not responding too.

It does not work for a long time, I think it has lost the support. Use xdebug-ext instead

Does not show up in toolbar so I can not enable it.

Not working with firefox 100.0.2 64bit, not showing in toolbar

Not working in FF 101.0

Installs cleanly, is easy to use, and runs reliably.

Many bugs with that extension and according to the list issues on Github, this extension is no longer actively maintained.

Works just fine for me with little configuration. Thank you!

In new versions of Firefox it does not add it's icon to the toolbar so it's basically useless.
