- Update *Tor Browser* to 9.0:
A gray border, called *letter boxing*, is now displayed around the content of web pages when you resize the window of Tor Browser.
[[!img doc/anonymous_internet/Tor_Browser/letter-boxing.png link="no" alt=""]]
Letter boxing prevents websites from identifying your browser based
on the size of its window. Letter boxing replaces the yellow warning that
was displayed until now when maximizing Tor Browser.
The onion icon has been removed from the top bar.
