User Agent: Mozilla/5.0 (Windows NT 5.1; rv:9.0.1) Gecko/20111221 Firefox/9.0.1 SeaMonkey/2.6.1 Build ID: 20111221001913 Steps to reproduce: * navigate to URL with anchor http://somewhere/page#anchor; a longer page. * scroll a little to another position * Page content changes in background * Press F5 for Reload Actual results: After page reload the browser jumps always back to the anchor position - amnesia about the scroll position. ( This jumpy behavior is not, when the current URL has no anchor: http://somewhere/page ) Expected results: After reload Moz should always use the smart reload algorithm (like with non-anchor URL) to preserve the current scroll position - like IE and Chrome do for good reason. The user 99.999% has forgotten/no knowledge that he navigated to a anchor (perhaps addition) and scrolled when he wants to update page. Navigating to an anchor has in the view of the user no higher prio than manuall scrolling - they are coequal means. The problem is unpleasant both for following pages during page develoment, and for following pages with some dynamic/updating (sub-)content. (Problem is same with Firefox when I remember right)

Works for me: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.20pre) Gecko/20110606 Lightning/1.0b2pre SeaMonkey/2.0.15pre Works for me: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:12.0a1) Gecko/20120115 Firefox/12.0a1 SeaMonkey/2.9a1 Try restarting SeaMonkey in Safe Mode: Go Help->Restart with Addons Disabled.
The "Restart with Addons Disabled" did not solve. Strange is that with most pages on the net (as your example) the problem is not. But I pinned it down to a very simple example - though I cannot say what it is exactly. Find attached test_anchor.html and empty.css I tried with different DTDs and charsets too - no symptom change. The bug is with Firefox too. But not with Chrome and IE. Strange: As soon as empty.css is not linked in the html file, then the problem disappears. The css can be non-empty as well to reproduce the problem. Just tried to pin down the problem. As soon as a css file is linked the problem is there.

found: as soon as an EXISTING .js file (can be empty) is loaded AFTER the css link, the problem disapears.

/With no .CSS/, if you are at the very top of the page ("line 1", if you will), then a page refresh /will/ jump to ANCHOR. Anywhere else other then at the very top of the page, then a page refresh maintains its position. With the .CSS, a page refresh always jumps to ANCHOR.
