[e10s disabled] Long-touch context menu is broken on Windows
User Agent: Mozilla/5.0 (Windows NT 6.3; Win64; x64; rv:50.0) Gecko/20100101 Firefox/50.0 Build ID: 20160824004001 Steps to reproduce: Long-touch any item in Firefox to open context menu (I have a laptop with a touchscreen) Actual results: * The menu that appears have wrong set of items (e.g. no 'View Image' for images). The items that appear seem random and usually affected by the last item I right-click (with mouse) * None of the menu items work - touching or clicking them (with a mouse) simply doesn't do anything. * On the first touch after Firefox starts the menu simply contain every single possible menu item: (see screenshot) - I simply long-touched the Firefox logo on that page Expected results: Context menu should work as expected. The same way it works when I'm using right-click to open it.
Tested in both Win 8.1 & Win 10 with the same result.
Torvin: Is this only broken on Firefox 50? If you could please try the current release or beta 49 it would be appreciated. Thanks.
Works fine in current beta (49.0b7)
ni on Andrei for further investigation. Not sure if you have a machine with a touchscreen you can test with.
I could reproduce this on a Microsoft Surface Pro 2 device with Windows 10 64-bit. On clean profiles this doesn't reproduce as the browser starts with e10s enabled. After restarting, e10s is automatically disabled and the issue occurs. On touch devices, also the contextual menu options are not working (Open in New Tab / New Window / ...) with e10s disabled. This is a Firefox 50 regression, introduced by bug 1256339: https://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=a706323c0073b7cd72dc0c41a6601a91f15dea9b&tochange=6172a55a6ae8611317b89f18ca47f785df4ab877

Summary: Long-touch context menu is broken on Windows → [e10s disabled] Long-touch context menu is broken on Windows
[Tracking Requested - why for this release]: Regression in Firefox 50 that affects devices with touch screens.
I think I'll just back out bug 1256339. I was mostly doing that in bug 1292572 anyway, to fix a different issue.
I guess technically I'm only going to back out one of the three patches, so I'll do in this bug after testing it locally.
This is the backout patch. I tested it locally to make sure it fixes the problem.

Pushed by firstname.lastname@example.org: https://hg.mozilla.org/integration/mozilla-inbound/rev/39710218be43 Revert the third patch from bug 1256339 because it broke long-press context menus in non-e10s mode. r=backout
Comment on attachment 8786044 [details] [diff] [review] Fix by backout of part 3 in bug 1256339 Approval Request Comment [Feature/regressing bug #]: bug 1256339 [User impact if declined]: on desktop with e10s disabled, long-pressing to bring up the context menu is broken in various ways [Describe test coverage new/current, TreeHerder]: There isn't any automated coverage of this touch long-press codepath, but I tested manually [Risks and why]: low risk, this is straight-up backout of one of the patches in the regressing bug. I'll fix that one a different way which I was planning on doing anyway [String/UUID change made/needed]: none
