Description

5 years ago
User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:17.0) Gecko/20100101 Firefox/17.0
Build ID: 20121128204232

Steps to reproduce:

Surf the web. WAIT a while for the page to COMPLETELY render and load content. Click on Alt+Left Arrow, or alternatively Back button on 5-button mouse.


Actual results:

Page did NOT go back after completely rendered.
If you DOUBLE click Alt+Left Arrow, or Back mouse button, then Page WILL go back. 
If you single click while page is still loading content, then it will go back.


Expected results:

Page should have gone back after one click of Alt+Left Arrow.

Note this affects Firefox 10 on my work laptop as well. IE is not showing this problem.
A similar  issue seems to have been reported years ago and fixed by a patch. Bug might have slipped through regression testing, and has been around for a few versions of Firefox.

This issue is reproducible even in Firefox Safe Mode.
alt+left arrow and backspace works for me with  Mozilla/5.0 (Windows NT 6.1; WOW64; rv:17.0) Gecko/20100101 Firefox/17.0

WFM too on Win 7.

Could you test with a new profile, please:

I tried it with the new profile - same result. I then did some more tests, and it now seems limited to a specific (news) website, where if you navigate away from the main page to articles on this same website, then Alt + Left click will not work.(Articles open in same window)

The key is to wait till all content & ads have been loaded and rendered. Check it out: http://www.king5.com/

Thanks!

Reproduced with 2012-12-17-03-08-50-mozilla-central-firefox-20.0a1.de.linux-x86_64

The site’s scripts probably do something that looks like following a link (I guess an anchor) to the browser.
