Great plugin that does what it promises.

Only one bug: It disables the ability to modify the current selection on the proxy dialog, so if you have selected another option but WPAD, it does reload WPAD settings.

Useful for me (for some reason my Firefox refuses to follow the system proxy settings as I get on and off the company VPN). However it breaks sometimes after new Firefox releases. Right now it's broken again on 78.4.0esr (64-bit).

Unable to edit PAC location with this extension installed.

Very useful, And thank you for your kindly update.
