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.
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 HKEY_CURRENT_USER or HKEY_CURRENT_USER \Software\Bayden Systems\UAPick. The list uses a pipe-delimited list of UA names and values.
IE14=Mozilla/14.0 (compat;)|FF6=Mozilla/14.0 (theFutureIsNeat)
Adds two new UA strings to the dropdown list, named “IE14” and “FF6”.
To suppress the default UA list included in the default UI, also create a new REG_DWORD named NoDefaults inside \Software\Bayden Systems\UAPick with value 1.
Fully Customized UI
You can completely replace the UI for UAPick by editing your registry.
Create a new REG_SZ named UI_URI inside HKEY_CURRENT_USER or HKEY_CURRENT_USER \Software\Bayden Systems\UAPick. This string value contains the URL to your HTML configuration file. For instance:
Note, you will need to restart IE after changing the UI_URI registry key.
Create a dialog using HTML in the specified location. A sample UI can be found here (right-click and Save Target As).
If you want to support a different size dialog, create a new REG_SZ named UI_OPTIONS inside HKCU\Software\Bayden Systems\UAPick. This string value contains the options for the open() command, for instance:
That’s all there is to it!
