This page lists known usability issues with the Tor Browser without reference to bug tickets. Fixed issues should be removed. This page should be formatted periodically into a mallard page for the [https://gitweb.torproject.org/tor-browser/user-manual.git Tor Browser User Manual]. Maintaining this page as a wiki will allow each support assistant to update it easily and quickly as he or she is alerted to new issues through [https://rt.torproject.org/ RT].
These known issues pertain to Tor Browser only and not to other Tor Project software. Tor known issues may be included only if they affect Tor Browser usability.

= Known Issues =
* Tor needs your system clock (and your time zone) to have the correct time.
* The following firewall software have been known to interfere with Tor and may need to be temporarily disabled:
* Webroot
* Kaspersky Internet Security 2012
* Sophos
* Microsoft Security Essentials
* Videos that require Adobe Flash are unavailable. Flash is disabled for security reasons. Most YouTube videos can be played with HTML5 by visiting the video's "Embed" → "Share" link.
* Tor can not use a bridge if a proxy is set.
* The Tor Browser package is dated January 1, 2000 00:00:00 UTC. This is to ensure that each software build is exactly reproducible.
* To run Tor Browser on Ubuntu, users need to execute a shell script. Open "Files" (Unity's explorer), open Preferences → Behavior Tab → Set "Run executable text files when they are opened" to "Ask every time", then OK. Tor Browser can also be started from the command line by running
{{{
./start-tor-browser
}}}
from inside the Tor Browser directory.
