I need to change the user agent on several computers that are using Firefox. Using the useragent setting in
about:config worked for several of the computers that are using an older browser. However, several PCs are using Firefox 7. Here, I am using the
general.useragent.override setting to change the user agent, but this does not remain in place after I close and reopen the browser. I also tried downloading the Firefox extension that allows you to set the useragent, but I can not find a way to set the new useragent by default; it all requires manual interaction from the user upon launch of the browser.
Is there a way to set the default useragent? (Preferably one that does not involve the registry).
