How to control what MIME types your browser accepts
I had a hunch that a web development problem had to do with different web elements historically being saved alternately in utf-8 and iso-8859-1. I decided to try tell the web server that my browser only accepted iso-8859-1, to see if I could trigger the bug.
I used the modify headers add-on for Firefox, and in it I specified like so:
I then verified on the server side that the headers were indeed altered.
The bug I was trying to find? Turned out not to have to do with this.
Add, modify and filter the HTTP request headers sent to web servers. This addon is particularly useful for Mobile web development, HTTP testing and privacy.
