The menu occasionally shows "recommendations" (ads!) for other add-ons that are not directly linked to the mozilla add-on page. This feels shady, and generally unsafe.

I feel uncomfortable using this add-on and have uninstalled it.

Just some constructive criticism: The headlined feature of UA randomization is not explained well and could be implemented better. Having additional functionality that is not streamlined is always better than not having it at all, so I can't complain much :)

移动界面不友好！

Nice addon for switching user-agent on Firefox PC and Firefox mobile version (I tested this addon on android platform, but I don't know how about iOS because I don't have a iPhone)

Very interesting!! I Love
