Description

[Ian]

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.2.6) Gecko/20100625 Firefox/3.6.6
Build Identifier: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.2.6) Gecko/20100625 Firefox/3.6.6

This is in an application I wrote, so I know the page has Cache-Control: store, no-cache, must-revalidate.  When I click on a link in this page, and then click Back, my scroll position is lost.

I tested this with Firefox 3.6.6 and with 3.5.10.  On 3.5.10, I am put back at my scroll position.  On 3.6.6, I am put at the top of the page.

Reproducible: Always

Steps to Reproduce:
1. Load page with proper cache-control settings
2. Follow a link in the page
3. Click back button
4. Sigh
Actual Results:  
View is at the top of the page.

Expected Results:  
View should be at the last vertical scroll position.

What, after nine months?  And when I told you exactly how to reproduce the bug?  Sorry, we moved on.  #bugzilla-fail

Except you didn't.  Using your steps to reproduce doesn't show the bug on a test page I just tried.  Hence the request for a testcase that does show the bug.

That said, is your page served over https perhaps?

Going to close this as INCOMPLETE as we were not sure about the original STRs.
I tried navigation back-n-forth on several random pages and random scroll positions. All worked fine.

Should be an issue with scroll position restoration after navigation on the latest firefox, please file a new issue. Thank you.
