Rated 5 out of 5 stars

Great add-on. I use it all the time when servers send files I can display in the browser but with the "wrong" headers.

Unfortunately, the add-on stopped working in Firefox Nightly (version 33). It still shows up but pressing the OK button does not do anything anymore. Can you take a look?

This review is for a previous version of the add-on (1.13.1-signed).
