Customize "Proxy is refusing connections" error messages in Tor Browser and remove the "Tor is not ready" popup
When you start TorBrowser before Tor is ready, there is a “Tor is not ready” pop-up, that ask to confirm if we want to start IceWeasel.
I feel we could remove it, because :
- it can lead to misunderstanding, like thinking that it could be a
probleme using TorBrowser without Tor ready
- there is a notification about Tor connection
