fd exhaustion issue - our soft limit is currently 800 fds which is exhausted pretty easily on high res macbooks. one fullscreen instance of a firefox tab at 3840x2400 (the virtual resolution used on a 15" MBP with the highest screen res option selected) uses ~150 tiles just for the visible content.
We also have issues with tiles being used for non-scrollable content, so increasing the tile size isn't really ideal (right now) as we'd be wasting quite a bit more memory
Current plan is to increase the soft limit for fds to the maximum the OS will allow us (reportedly ~8000, so an order of magnitude increase), then long term work on using non-tiled layers for non-scrollable content, and increasing the tile size on desktop to something like 512x512, which should quarter the number of fds we use.

bug 1126164 (non-e10s regression from plugin work) - fixed
bug 1116884 (m5, crash in WaitForSingleObjectEx) - wip

bugs 1092121, 1092121, 1077085 from last week landed.

M4 - bug 1108761 - Add class to let menulist > menupopup stylings apply to other popups
- Finally landed!
- Not that huge a difference on OS X or Linux, but it's a huge change for Windows.
M5 - bug 1126311 - Disable OMTC warning for new e10s windows on Linux if browser.remote.tabs.autostart.1 is true
- Fixed, landed.
M5 - bug 1077168 - Installing an app on marketplace fails with e10s
- Have a patch up, waiting for review
M5 - bug 1047603 - [e10s] Non-remote tabs in e10s windows do not handle target="_blank" or window.open links properly
- Got review from Mossop, addressing review feedback
M5 - bug 1112243 - [e10s] <select> dropdowns are blank, if there are many options (e.g. at http://www.bls.gov/data/inflation_calculator.htm )
- Seems to be a general problem with menupopups that have scrollbars and short labels
- Have a hacky workaround, but I'm talking with Enn right now about a better fix to the nsMenuPopupFrame preferred-size code
M5 - bug 1090448 - Make e10s printing work on Linux
- Started investigating this again. It's mostly a problem of serialization and deserialization, and figuring out what I need to send over. So I'm not too worried about this. Yet.
