User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:42.0) Gecko/20100101 Firefox/42.0 Build ID: 20150814004009 Steps to reproduce: 1. Updated Firefox to 42.0a2 (2015-08-14). Host is 64-bit Debian "stretch". 2. Got the message that e10s was enabled. Went about my typical browsing. 3. TweetDeck works fine. Clicked on a GMail bookmark and nothing happened. Actual results: I opened a new tab and typed in the GMail URL. It just stalled. I disabled e10s and restarted. It took a while for it to connect but GMail eventually came up. Other Google services - Drive, for example - seem to be working both with and without e10s. It looks like only GMail is having problems.
I don't think this is just e10s and it seems to be many of the Google services. I've also seen some big CPU load numbers from Firefox in 'top'. GMail is the worst but Google Drive and Sheets are also showing problems.
I tried Nightly (43) and it seems to be slightly better - GMail opens with e10s disabled, but I can't open a folder.
Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:43.0) Gecko/20100101 Firefox/43.0 ID:20150815030208 CSet: 2ddfc9180971a212127a370911ba2e8ef36a6605 WITHOUT e10s turned on. Today, this update, it's not working for me with Gmail. I click on an email to read it, and Gmail still says "Still working..." at the top of the window. Meanwhile, Chrome is working, I started reading email, got the notification that this was an e10s, opened up the link, copied the link and opened it in Firefox, not Chrome (already logged in). And Gmail is still working... Uh-huh.
As I expected, it's working fine on Windows (8.1 Pro, 64-bit, Intel CPU) - Firefox Developer Edition 42.0a2 (2015-08-15)
