I've noticed that the go-back button gets confused (or history gets confused or something) from time to time. I notice this quite often. Start on the mozilla.org page, then go to the travelocity home page, above. If you click on the Find/Book A Flight button, then go back (try this several times), sometimes you'll end up back at the mozilla.org page instead of the travelocity home page. If you go forward at this point, you'll be able to jump from www.mozilla.org to the travelocity login page, without the travelocity home page inbetween.

Reproduced with 1999-10-17-08-M11 on WinNT 4.0sp3 Comments: I've seen this many times before but didn't know how to characterise it. The same double-go-back can bee seen in some circumstances moving among bugzilla pages. Comparing bugzilla and travelocity the common element that comes to mind is HTTP 301 and/or 302 response codes. If the history-stack code is remembering that the browser took two steps forward, but elides the intermediate page from the stack, two steps back would be one step too far.

This is a dup of 16782 ( the post data problem) instead of 17430. *** This bug has been marked as a duplicate of 16782 ***

Verified as a dup.
