Assigning to Roc to take a look at this regression based on comment 1 - should comment 2 be a separate bug?

Also adding qawanted to see if this is present at all in 16

I think this is probably a duplicate of bug 787947.

(Tested try build, fixed (per Win Opt Build))

I cannot reproduce this bug using Win 7 64-bit and today's Aurora build.

I can still reproduce in Aurora17.0a2 with disabled HWA. http://hg.mozilla.org/releases/mozilla-aurora/rev/97d5b2b09fb8 Mozilla/5.0 (Windows NT 6.1; WOW64; rv:17.0) Gecko/17.0 Firefox/17.0 ID:20121005042010

(In reply to Lukas Blakk [:lsblakk] from comment #4) > Also adding qawanted to see if this is present at all in 16 I think the time for this in Firefox 16 has come and gone, unless we can reasonably land a fix in time for a 16.0.2. Please re-add qawanted if this is the case.

Well yes, my request 2 weeks ago to see if this was still in 16 isn't that relevant now, however comment 8 says this can still be reproduced in Aurora17.0a2 - so please confirm that this is still present in 17 on Beta just to confirm Roc's suspicion in comment 5 that this is a dupe of bug 787947 (which is marked fixed on 17).

Thanks Alice. Lukas, can we dupe this now?
