[tor-talk] Unseen.is login page blocked in TBB

[Joe Btfsplk]

On https://Unseen.is, the page(s) that would normally come after 
entering user name & PW is blocked.
Instead, submitting login data & page "refreshes",  I just see a blank 
web page w/ a "throbber" in middle of page.
Same thing happens when creating a free acct - at top of page at address 
in above link.

After submitting data for new acct, browser refreshes, new page loads & 
the blank page w/ throbber just sits.  But (for me), the acct was 
actually created.
I found that out from their support.
FYI:  to create an acct, don't actually need a *valid* "Primary Email 
Acct."*  You have to enter an address in the form, but I don't think it 
has to be working, or it can be a disposable address.

After submit login data, even though the page is now blank, the URL in 
address bar has changed (from orig. Unseen.is), to reflect (I believe) 
the next page that's normally displayed after login.
*Login works* - using a standard Fx profile (even w/ NoScript & some 
other addons).  In a regular profile, after submitting the login data, 
the SAME blank page w/ a throbber appears for a few seconds, then 
disappears.

Difference being, in a regular profile, the blank page w/ throbber 
disappears after a few sec & brings up next page.  In TBB, the blank 
page never disappears.
Even after the URL in address bar has changed, I also can't just delete 
the "node" for the blank page (overlay), to reveal the 1st page inside 
my account.
I was unable to tell from Fx web console, what causes the blank page to 
permanently hang.  Someone else might be able to see it.

I've noticed the exact same problem in regular Fx... IF... I use the 
"JonDoFox" profile -  created by the extension of same name.
The profile that JonDoFox creates, makes many of the same changes to 
prevent browser fingerprinting that TBB and / or Torbutton make.

Javascript is enabled for Unseen.is domain in all cases.  In NoScript, I 
tried both whitelisting it & allowing scripts globally - no difference.

Login on this siteSince in a regular Fx profile works, but not in TBB or 
a JonDoFox profile.
The "regular" Fx profile can contain NoScript, Ghostery, Adblock Plus, 
CookieMonster, HTTPS Everywhere, etc., & still allow login.  So, 
guessing? it's not those extensions causing the problem.

I even disabled and / or uninstalled potential problem extensions 
(NoScript, etc.) in both TBB & the JonDoFox profile - no change.
I conclude the issue is a change made by *both* TBB (or Torbutton) and 
JonDoFox extension.

Either it's some - other - change made (assuming in about:config) by 
both TBB & JonDoFox, that is NOT directly related to their included 
addons...;
OR... the problem is some change(s) that *IS associated* w/ their 
included addons (NoScript, etc.) but *disabling or uninstalling* the 
extensions installed by TBB & JonDoFox, doesn't correctly reset all 
about:config changes they made.

Unseen's support dept was clueless.   They definitely don't block TBB / Tor.
If anyone has an Unseen acct or wants to look / try creating a free 
acct, be aware they're upgrading part of their system "for couple hrs" 
as of Sun. 3/2 @ approx. 2 PM, Pacific Std. Time.
So it may not be available for a while.

Thanks.
