Status: RESOLVED WORKSFORME

(Core :: JavaScript Engine, defect)

Description

[Zen]

Attachment: drop down.png

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:12.0a1) Gecko/20120111 Firefox/12.0a1
Build ID: 20120111031049

Steps to reproduce:

Tested the drop down button list on a website:
http://www8.hp.com/au/en/software/software-product.html?compURI=tcm:184-935779&jumpid=ex_r163_au/en/large/eb/qm_ldrungen_google_apjsem_dg/&k_clickid=APJ|5b2ec284-9d8f-8ae9-2a91-0000794352b3

and discovered that the "let's talk" and "trials and demos" did not respond.

Tested it in version 9 as well as other browsers and confirmed that the button is working.


Actual results:

The list did not drop down and there was no response from the site.


Expected results:

The list should have dropped down with a click on the button and the user would get to select from the list.

[Brian Hackett [Laid off!]]

WFM with the patches in bug 717184 and bug 717208 applied (not sure which is the fix, and confirmed broken without them), should retest once those patches land.

Confirmed WFM in Jan 17 nightly (and not working in Jan 12 nightly).

Comment 4

[Alex Keybl [:akeybl]]

Tracking for FF12 given the possible web incompatibilities.

Dave - did we ever figure out which changes caused/fixed this bug? We should likely uplift to Aurora 12.

Sorry, this is a regression in 12, fixed in 12. Ignore my last comment.
