As part of building up this new computer, it's starting out with FireFox and Thunderbird. One of the issues I've run into with Firefox is that certain web sites check the browser version that's transmitted, and if it doesn't come back high enough (IE 5.5 or higher, for example), you aren't allowed in. I thought there was an extension that took care of this, but a quick check of the extension list isn't promising, and neither was a search of the IW GD history.

Any one have any thoughts, or can point me in the right direction?

Thanks :D

Allows you to change the user agent that firefox will use. You should also be able to do this with about:config, filter for agent. But I dont know the specifics.

Thanks, Andrewas. I've downloaded it and will see if it lets me access our work VPN tomorrow.
