I Ihave around 50 tabs in FF, but active only maybe 15-20. On Mac OS I see a standard problem when I connect external monitor after wakeup, FF starts to "eat" memory like crazy, until I either kill it, or it's crashed. I need to restart FF every 2 days to get my memory back. Here is screenshot from App monitor: https://www.dropbox.com/s/rh133wnhk1wgbe2/Screen%20Shot%2020...

Sometimes, after 2 days of work each worker consumes ~7Gb of RAM (on machine with 16GB of RAM)...

P.S. mostly opened documents in google doc, gmail, calendar, JIRA/Confluence...

There is a well-known bug[1] with non-standard resolutions. Try changing the resolution and see if it makes any difference. If not, please file a new bug :). Otherwise you can see if you can help fixing the issue. Unfortunately, it requires some re-engineering of core graphics processing and they are working on it, but it'll likely take a few more months to fix completely.

[1] I think this was the bug I thought about: https://bugzilla.mozilla.org/show_bug.cgi?id=1404042, see also https://bugzilla.mozilla.org/show_bug.cgi?id=1422090
