Rated 4 out of 5 stars
This addon is extremely useful for me. Where I work, we have load balanced servers for our websites, so the only way to know which actual server you are hitting is by a custom header. With this addon you can show whatever header field you want in your status bar with the proper configuration. The only slight is that the configuration is a little weird and I had to fiddle with it a while to get it to do what I needed.This review is for a previous version of the add-on (1.3.4).
I'll fix configuration dialog to make it less weird. Thank you for using Header Spy.
