FlexHeaders - Modify HTTP Headers

Perfect extension, does exactly what it's meant to do and nothing else superfluous.

Easy to use, just works as intended. Thanks :)

Fantastic extension. I've started using this since other extensions are trying to do a little too much and far more than what I need for my use case. This extension does exactly what I need. It is easy to use and well designed. A great job!

Hey, would you consider making this open source? Great extension.

The new modheader.com extension looks and acts like a spyware now. It collects way too much info. Honestly it should be banned. Took me a while to figure out a good extension that will let me easily modify the headers without loading a new options page and jumping through a bunch of hoops. Great Job. Hope this gets more popular.

im first! very good of this extension, simple and useful
