There are browser extensions but you might not even need it if you use the Autotype function.
The auto-type works fine for me with the Firefox Keepass helper url-in-title addon.
You can also trigger Global Auto-Type from the browser extension with seperate keyboard shortcut (or using context menu), and it handles the URL matching with Auto-Type without any extra extensions.

I don't see how switching to a different extension will improve anything.... I have global auto-type binded to CTRL-SHIFT-C and it just works
