Getting further away from a domain-wide distribution of torbrowser, now if you delete tor launcher extension, tor button won't allow you to specify network settings....
In another ticket, along with talking with devs, I spoke of how, at the request of users, we was trying to deploy TorBrowser since we don't allow employees to execute any .exe.
The dev's (unknown) were supportive of fixing the issue but now there is another issue that may or may not be fixed when torbutton gets fixed, for the other addons issue encounterred.
When you delete torlauncher extension from the default pref folder, since we run a centralized, redundant cluster of tor.exe servers, tor button will not let you specify the socks & http(s) proxies. If you click the tor button uhhh button :) and select _Tor Network Settings, _nothing appears or pops up.
I haven't confirmed this is from removing tor launcher extension but, since no one else has reported it, I just assume.
