When I use google search, google.com, and click on a link in the search results I get a 400 Error, Bad Gateway using Firefox.  In Chrome no problem.

I am wondering why this is happening on FF; and it happens with the new search thing in the top Boonex menu as well.  Very annoying.

Anyone else seeing this behaviour?

Nope. And i have no clue.

Firefox works fine for me. On google and on the dolphin search form. No issues.

Probably one of those magical Nginx quirks.

If I do a right-click on a forum topic and say open in new tab:

FF 19.0.2. I have not upgraded because the last time I upgraded FF, it caused a lot of issues. I have added no new add-ons. It just started doing this one day. I guess I could download the latest FF and see if it stops.  By the way, that version of nginx is outdated.  The current stable release is 1.4.1.

By the way, it works fine on Google for other sites, it is only on Boonex search results including the one through the google search on the Boonex black menu bar above.

try creating a new firefox profile - then only update that profile - and see if it works or doesnt work

Lycos says deleting cookies might work.  But Lycos says a lot of things.

Nathan is right, clearing cookies should help.

I had to shut my computer while I was away, appears to be working now.  Or maybe Boonex did something :-).  Maybe the gremlins got hungry and left.
