When I visit Twitter with SeaMonkey (latest version on Windows) I get 
"Something went wrong." with a "try again" button that does nothing.
It works fine on other browsers on the same machine.

I have tried deleting all the Twitter related cookies and logging in again 
fresh and that didn't work.

Anyone else seen this or got any suggestions?

I noticed Twitter wants send referers to work. Do you have that 
disabled? Also, have you tried a new SM profile yet?

I tried another profile, that didn't help.
And I have referrers turned on.

For me, with SeaMonkey 2.53.5.1 on Linux set to show the user agent as 
just SeaMonkey (no Firefox compatibility), https://twitter.com/ shows 
"This browser is no longer supported".  If I select "Identify as 
SeaMonkey and advertise Firefox compatibility" (which appears to be what 
you have), and enable JavaScript for Twitter's domains, it seems to work 
as expected - at least for the home page and a couple of feeds I looked 
at as a quick check.

 From your user-agent header it looks like you're on SeaMonkey 2.53.5, 
so maybe an update to 2.53.5.1 might help.

I don't have an account on Twitter and don't even view it much, so there 
may be other parts which don't work, but their home page looks OK to me.
