Was alternatively using requestly to handle this specific use case, but with the direction they've been going this has been a really nice alternative

As Security Researcher, I've found this add-on very useful.
I never even had any bug or issue.
Absolutely 5 stars!! <3 💯 ❤️

awesome, using it to add a specific header which Nginx uses to authorize the webbrowser and trowing a 404 if missing

Got to say like using this software it does the job and does it good and allows you to tweak any header you desire. Good job!

Great and usefull exention. Thk.

Cool extension, which works in private mode! This was very important for me (private mode) and other popular extension didn't work.
So, I recommend this!

works for modifying "host:" header
