Modify Headers works in a different way to the UA Switcher. Instead of updating system preferences, it modifies the request directly by using the observer service and observing the “http-on-modify-request”.

This allows the addon to modify any request header and is not restricted to user-agents only.

I would like to know which internal preferences are being changed by your addon, so I may compare and nail the coffin on this annoyance. The specific settings in ‘User Agent Switcher’ are listed below. Thanks in advance for your feedback.

[code]
general.appname.override
general.appversion.override
general.platform.override
general.useragent.override
general.useragent.vendor
general.useragent.vendorSub
[/code]

Simple (thanks to you!)

Firefox > Modify Headers > ‘Add’ > (Name) Cache-Control > (Value) no-transform > Configuration > (check) Always on……

This solves the problem of compressed data to my laptop, via T-Mobile (UK) 3G broadband link.

I prefer Firefox over IE7, but the latter sometimes inevitable. There must be a similar solution (can’t find it)!?!

I don’t plan on doing something similar for IE 7. But you might be able to find an IE 7 addon that does.

BTW, feel free to post in a comment a description (or link to it) of how you are using Modify Headers for your compression problem. I use it for mobile web development, but I’m always interested to see the other uses it has.

Thanks for this brilliant Add-on (Modify Headers), which has alleviated my problem of compression in Firefox via a 3G broadband link.

No chance I suppose of something similar for IE7?!?

If not, perhaps I could trouble you for a suggestion to modify ‘Cache-Control’ to ‘no transform’ in IE7 (?).

Thanks again.
