I wonder if that's a new problem with Tor Browser 7. Could you test with an older one (e.g. 6.5.2)? See: https://archive.torproject.org/tor-package-archive/torbrowser/6.5.2/ for bundles. Make sure your test session starts without the security-slider-hint-notification bar which you see on the very first start.

Interesting. Do you feel like you could test a vanilla Firefox beta (55b10) which is containing the same patches we ship. You can find it on https://ftp.mozilla.org/pub/firefox/releases/55.0b10/mac/en-US/. After first start you need to enable fingerprinting resistance by setting privacy.resistFingerprinting to true. After restarting could you make your test again and share the results in this ticket?

Hm. Where does that "startpages" item come from? Is that a toolbar that is on by default? I wonder whether an older Firefox you had on your computer could cause this and thus interfere with the test.

I had the stable version of Firefox installed before a test at the Beta, I can retry to test by first deleting all of Firefox preference files,

That might help. Or just creating a new profile via about:profiles and using that one for the test. Thanks!

After I deleted all the Firefox preference files I got these results. Browser window width: 1000 Browser window height: 600 I retested Tor browser bundle 7.0.2 and still got the same results. Browser window width: 1000 Browser window height: 610

Thanks. Could you test Tor Browser with NoScript and/or HTTPS Everywhere being disabled? Maybe having their toolbar buttons injected into the toolbar is causing this.
