OK - thanks. FYI if you want to try & reproduce it, I tried it in a
couple of Tor Browser versions (TBB) - still does it in current 6.0.8
(Windows - don't know if it does in Linux, Mac).
Still happened when DISabled NoScript & HTTPS Everywhere - but left uBo
enabled, then restarted TBB - to rule out conflicts.
The only addons left were default Tor Launcher & TorButton. Have no plugins.
01/04/17 - D/L TBB-win 6.0.8 fresh copy - installed to new folder.
Left all settings @ default, except had to restart a 2nd time before it
allowed installing any addons. But then uBo 1.9.16 installed w/o a
hitch. Changed no uBo settings - just restarted TBB after uBo install.
Result: if uBo is ENABLED, TBB screen is taller than from the top of
monitor & the top of Windows task bar (a 4:3 widescreen monitor).
If uBo is DISABLED (& restart TBB), then TBB's height is "normal."
UBo's icon being on toolbar or not - while uBo is enabled - makes no
difference on my box.
Once, in a new TBB install, after clicking "New identity" from the green
onion icon on toolbar, & TBB screen size seemed normal, I took uBo's
icon off the toolbar. On the 1st restart after that, screen size was
normal (not longer than monitor's height), but on the 2nd restart the
Again, w/ uBo enabled & when TBB starts w/ browser UI taller than the
visible area of monitor, clicking "get new identity" under the green
onion icon (which is Tor Button), then TBB's height returns to normal.
A "new identity" closes all browser tabs, deletes cookies & exceptions,
clears memory cache & any other data accumulated while browsing.
TBB devs use some sort of browser screen size "spoofing," to manipulate
the browser screen size when it starts. Could uBo be detecting this or
interfering? I honestly don't know what method they use (now) to spoof
screen sizes or control the NON MAXIMIZED startup screen size. They've
changed / tweaked how they do it - multiple times, to try & get it to
reliably report usable screen sizes in multiples of 100, but seem to
constantly run into problems. That's a separate issue than uBo making
TBB taller than the monitor, but could be related??
