User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.9) Gecko/20050711 Firefox/1.0.5

Firefox 1.0.5 occasionally goes to the WRONG URL when using the Back Button. 

I've seen this same bug on a pc at my office and on a pc at my home.

The URL that gets returned to is one of the ones in the current history.
(Usually 3 or more items in the history list.)

It usually happens when there is ONLY 1 tab in use. 

Seems like the pointer in the URL list is improperly updated when the back
button is pressed. (i. e. pointer index seems to be off by 1 or more.)

Seems that when I have hit the button multiple times, without pressing the
button too fast or too often, that when it returns to the "root" item that the
pointer is off by 1 or more.

To fix the problem, I have to exit Firefox and restart Firefox.

Reproducible: Sometimes

Steps to Reproduce:
Not sure how to reproduce the problem.

It occurs on different web sites.

Actual Results:  
See Details above.

Expected Results:  
The browser should parse the history list forward and backwards properly.

Bill New, are you using any extensions with Firefox?

Comment 2

[Bill New]

Tools Menu and Extensions shows nothing. Any other ideas on what I should check on?

I press the back button once and it will skip the previous webpage to the one
before the previous webpage. This is still a problem in 1.0.6.

Can anyone reproduce this with a current Firefox 2 or 3 build?
