1244560 - Browser keeps going back a page for no reason.

Status: RESOLVED DUPLICATE of bug 1244517

(Firefox :: Untriaged, defect)

Description

[dragonchaser]

User Agent: Mozilla/5.0 (Windows NT 6.0; WOW64; rv:44.0) Gecko/20100101 Firefox/44.0
Build ID: 20160123151951

Steps to reproduce:

Navigated to http://smith-wessonforum.com/forum.php. Attempted to navigate to a subforum using the mouse. 


Actual results:

When selecting any of the subforums and clicking to go there, the new address will appear in the address field of the browser, but will often switch back to the initial page. Behaviour is worse if the mouse is moved while the second page is loading or I switch to another tab while the second page is loading. If I stay on the tab and don't move the mouse, the subforum loads most times, but occasionally it goes back a page regardless.


Expected results:

I should be able to navigate between forums. The problem started Friday 29 January 2016.

I can reproduce this and the caller for history.go(-1) is

So, Google has changed something recently.
