Right now the total memory used (by everything running, including the OS), according to the Windows Task Manger, is 3.10GB. I just got home minutes ago, fired up Firefox Nightly, and came directly to this thread. So, right now in addition to Firefox there is the start-up shell for LibreOffice, Norton Security Suite, and I noticed when I had installed the drivers for my new printer (a Brother laser printer) it ate a good chunk of memory.The Tinsmith wrote:The times I have looked at the Task Manager and had just Firefox Nightly up and running and was not displaying my Netflix DVD Queue or a long ways down an infinitely expanding page, total memory usage was under 4GB. (E. g., right now it's sitting at 3.54GB.)
I am always amazed when I see users here talk about high Firefox memory usage. I don't have a Netflix account so I don't have your queue so I can't try that but sitting here, right now, logged onto this site Firefox Nightly is only using 297 MB of ram.
So you must have something else 'running'.
Let me shut down Firefox to get a baseline reading ....
2.66 GB with Firefox Nightly shut down. 3.10 GB after starting Firefox Nightly again (after updating). So it looks like Firefox Nightly by itself after looking at just this thread is consuming 0.44 GB.
After opening a number of tabs (with dom.ipc.processCount set to 10, opening Titan TV, Netflix DVD home, IMDB, Netflix DVD queue, Netflix Instant Queue), total memory usage climbed to 3.83GB, so the Firefox portion is 1.17 GB. After scrolling through the Netflix DVD queue so all the cover art pictures loaded, it ate only another 0.03 GB.
For extensions, I am using uBlock Origin, Violentmonkey, Country Flag +, Hostname in Title, IPvFoo, small-clock, Tab Center Redux, To Google Translate, Blank New Tab.
This is a 64-bit build of Nightly on Windows 7 Home Premium SP1 (64-bit).
