As far as I know, using a site specific user agent override was a feature dropped from Firefox and therefore TFF - is it possible to bring it back without causing problems?
I found it was useful to adjust the config file to use different user agents on a site by site basis.

    It looks like this was pulled in

    It should be possible to revert that, but the reason they took it out was a non-trivial 9% performance hit, so this isn't a slam-dunk. I might see if a master pref can be used to control it such that if the pref isn't set, the browser doesn't initialize it.

    Thanks - appreciate that. If it really does drag browser performance down 9% that's an unacceptable negative on PPC Macs which need every CPU cycle they can muster.

    A first pass is in the FPR17 beta, which appears to basically work with my simple testing. I have decided I don't want to officially support it, but I'll leave it there for people who understand its limitations and risks. See

    That's great - thank you. I'll download the beta and test asap. Cheers.

    The problem since FPR17 is, that I can't configure extensions like NoScript or Ghostery. There is no configuation button in extensions menu like before. Any suggestions?

    Please don't tag on to existing tickets if you have a new concern -- please open a new one.

    In response to your query, I didn't make any changes to add-on compatibility in FPR17. If you like, please open a new ticket with what version of the add-ons you are using and where you got them from. A screenshot showing exactly what you're referring to that's missing would be helpful.
