You're a lifesaver! This plugin actually works ^_^

I can't get it to work in Firefox 129.0. Also, I'm missing a hint, whether the regex-matches get excluded from CORS (then the default setting would be very dangerous), or included? And what when the button is set to disabled? Is the URL list in charge then? Or is it in charge, when enabled? And, do I have to match my local domain oder the remote?
So, in all, seems like a nice plugin, if it were working, and if it was more clear about what the settings mean.

Works but not so friendly interface.
Make sure to ADD and SAFE the URL.
If you make a request from e.g. localhost to someServer you have to add the URL of someServer.
Took me some 20min to figure out since it is unclear from the user interface.
