[tor-talk] Will enabling extensions.torbutton.resize_windows; true have a downside?

[Joe Btfsplk]

In TBB 6.08, there's a torbutton pref in about:config - 
"extensions.torbutton.resize_windows" = false, by default.
I understand it's enabled in TBB 6.5a (maybe not).

The resizing of my screen height in 6.08 is sketchy.  But if I enable 
the pref above, seems to make height resizing consistent to an even 
multiple of 100.
I wonder if there are undocumented issues with turning it on in v6.08?  
If there's good reason to leave it off in this version, even though it 
seems to improve resizing for me?

Question 2:  There's tons of discussion on sites detecting *installed 
fonts* in browsers & TBB's efforts to prevent it, or just present a 
fixed, short list of fonts.
Has anyone seen reputable data about sites detecting the named *serif 
font,* its size or the "minimum font size" in TBB?

Whether sites (that care) can detect if you changed the default Times 
New Roman font - size 16?  I've found almost nothing on that.
Secondly, the default setting in Content> Advanced, for "minimum font 
size - None" can wreak havoc on me if "Allow pages to choose their own 
fonts..." is also left checked (default).
I wonder if they can detect that you've changed minimum font size to 
something reasonable, like 13 - 14?

When pages use very small fonts & there's no lower limit in TBB,  it can 
be unreadable.   At some point, I may have to concede letting them 
detect I've made a font size change, or just not read some pages.  But, 
it's been 2 yrs for many that screen height resizing didn't work 
correctly & apparently that wasn't a giant concern.
Thanks.
