This small little add-on allows you to quickly customize the User-Agent string sent by IE8 without restarting.

After installing, click "Set User-Agent String" on the classic Tools menu to launch the add-on. If you do not check the "Reuse this UA" box, the user-agent will revert to the default UA string in new IE processes. 

If you'd like to add a toolbar button, right-click the IE toolbar and choose "Customize."  Move the "UA Button" entry from the "Available" column to the "Current" column.

Testing the User-Agent string

There's a UA-string test page here: http://www.enhanceie.com/ua.aspx

Adding custom User-Agent strings

You can add custom user-agent strings to this tool by editing your registry.

Create a new REG_SZ named CustomUAList inside HKLM\Software\Bayden Systems\UAPick.  The list uses a pipe-delimited list of UA names and values.  For instance:

IE14=Mozilla/14.0 (compat;)|FF6=Mozilla/14.0 (theFutureIsNeat)

Adds two new UA strings to the dropdown list, named "IE14" and "FF6".
