Two Alt+Left Arrow clicks required to Go Back One Page (something a page does adds to history subtly)
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: https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles
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.

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.
