* Start Tor Browser Bundle. Close Tor Browser for various reasons ^1^, leave Tor and/or Vidalia running for various reasons ^2^ and restart Tor Browser later. (#6023) ([https://www.torproject.org/docs/faq.html.en#TBBCloseBrowser Tor FAQ]) (#6090)
* Start only Vidalia/Tor, but do not start Tor Browser.
* Thunderbird with TorBirdy wants to use Tor/Vidalia from the bundle or a locally installed Tor/Vidalia. TorBirdy also depends on privoxy.
* Tor IM Bundle ([https://blog.torproject.org/blog/tor-im-browser-bundle-discontinued-temporarily blog]) want to use Tor/Vidalia form the bundle or a locally installed Tor/Vidalia.
* Ubuntu users (and probable other deb based distributions) want to 'apt-get install tor vidalia torbrowser' from torproject.org repository (#5236)
* Debian users want to 'apt-get install tor vidalia torbrowser' from Debian repository (#3994)
* Start Tor Browser with command line arguments supported by Firefox, such as open an extra tab. (#6053)
* Reopen Tor Browser from Vidalia. (#6090) (#5693)
* Subsequently also reopen Tor-IM from Vidalia.
* Developers want to make their portable Tor Bundle packages. For example: BitCoin, [http://archetwist.com/en/node/7 OperaTor], [https://github.com/prof7bit/TorChat torchat], [[https://github.com/prof7bit/TorChat pidgin-torchat], [https://github.com/jtorchat/jtorchat jtorchat]. But (some/most) of that projects would like to play well with a locally installed Tor/Vidalia as well.
* Tails (has their own Tor/Vidala integration) wants to use Tor Browser. ([https://tails.boum.org/todo/replace_iceweasel_with_Torbrowser/ Tails todo])
* Use Tor Browser behind transparent or isolating proxies. (#5611)
* Tell Vidalia, they want to avoid connecting to the public Tor network. (#2905)
* To use environment variable TOR_TRANSPROXY=1. (#6254) (#5658)
* Have a handshake protocol between Vidalia, Tor Browser, Tor, Tor Router. (#5658)
* Use environment variables for configuring. (#5611) Example:
TB_RECOMMEND=1 (set back recommend default proxy settings)
}}}
* Stream isolate Tor Browser, Tor IM, Thunderbird with TorBirdy and third party applications. (#6359) Due to lack of SocksAuth support in Firefox and Thunderbird, this requires using multiple Tor SocksPorts.
* Use multiple instances of Tor Browser at the same time.
* Independently run Firefox (non-Tor) and Tor Browser (Tor) at the same time.
* Application developers (torchat, BitCoin) want to have hidden service as incoming address for their application.
,, ^1^ 1. Safe RAM, 2. Restart in case of a bug, 3. revert to a clean state (things Tor Button does not implement yet to clean up with switch identity feature) [[BR]]
,, ^2^ 1. To speed up the startup process of Tor Browser, 2. to use the running Tor instance for other torified applications [[BR]]
