Reproducible: Always Steps to Reproduce: 1. Navigate to the URL 2. click a personal toolbar bookmark 3. click back 4. select some text and right click Actual Results: Note the greyed out Copy, and Select All options. Also note that the ctrl-a and ctrl-c keyboard shortcuts don't work. -So far I can only reproduce this when a mozilla.org page is the original URL in step 1, wikimo works too. -It only seems to happen when you click a personal toolbar item. -refreshing the page restores the copy/select all

So I've now reproduced it on a number of sites and it's officially a regression :/ G: http://bonsai.mozilla.org/cvsquery.cgi?module=PhoenixTinderbox&date=explicit&mindate=1208978640&maxdate=1208986379 NG: http://bonsai.mozilla.org/cvsquery.cgi?module=PhoenixTinderbox&date=explicit&mindate=1208986380&maxdate=1208993639 Likely culprit is bug 386782 Simplified steps btw: 1. Click a personal toolbar link (wait for full page load) 2. click back 3. Try to copy or select-all This is likely to be OS All, but I can't confirm that.

Likely a regression, confirming.
