Description

[Mike Sirianno]

User Agent: Mozilla/5.0 (Windows NT 6.1; rv:57.0) Gecko/20100101 Firefox/57.0
Build ID: 20171112125346

Steps to reproduce:

Two tabs open.


Actual results:

Seven Firefox processes open using well over 1 GB of memory.


Expected results:

Don't expect this much memory to be used.  And why seven processes?  Firefox is slowing becoming not my favorite browser.

How are you measuring memory used?  For example, N mozilla processes will all share 1 copy of code/libraries/etc.  Also, what sites?  Some sites will use over 1GB of memory if you leave them sitting (bad code on the website leaking objects), though normally that's all recovered if you browse away.

If you save an (anonymized) memory report saved from about:memory, we can look at the details.  Knowing what the two sites are would help too (and the OS)

I'm checking memory thru Task Manager.  Websites were Facebook and Miami Airport.  OS is Win 7.  I have the anonymized memory report.  Who do I send it too??

You can attach the memory report here.

Mike, do you happen to have the extension HTTPS Everywhere installed? If so, what version is it?

I've seen someone report similar experience (may requiredsome time to remember where)

Note that Facebook can *easily* use over 1GB depending on what's in your feed, how long it's been open, how much you scrolled, what ads are shown.  And that could be valid, or a leak, or a bug in facebook's code (which happens on a moderately frequent basis, though they're also usually responsive if it can be pointed out to them)
