Memory & Jank issues (/questions/1011071 &see998289)
I have noticed for awhile that Firefox is consuming too much memory - 100's Mb more than erxpected. This morning I noticed massive 2.4Gb in Win7 64bit task manager even though there were only 4 tabs open on static websites and it had used as many as say 12 tabs at max, including sites with short advertising-style videos but nothing large.
I see on the threads that this is a problem you have and are not fixing. Combined with a general decline in Mozilla that's not good. For instance I find enfdless flash problems even though I keep that more or less up to date.
Firefox version is: 38.0.1

The developers are constantly working on streamlining memory use. And also adding new features, so perhaps you might not notice that much change in the end. Still, it is unusual to have Firefox using more than 2GB of memory. Does that happen often?
(Usually I don't see 2GB until I've got 20+ windows and 60+ tabs open and busy for over 24 hours, but I use the NoScript extension to stop unnecessary excess stuff running on sites.)
This is some standard guidance that addresses the most common issues with the Flash Player plugin. I'm sure you've seen some of it before, but just in case:
(1) If you have any recorders/downloaders that interact with Flash media make sure they are as up-to-date as possible, or disable them temporarily.
(2) Disable hardware acceleration in Firefox and in Flash
(A) In Firefox, un-check the box here:
"3-bar" menu button (or Tools menu) > Options > Advanced > General > "Use hardware acceleration when available"
That takes effect the next time you exit and start Firefox up again.
(B) In Flash, right-click the media and choose Settings, then the first mini-tab and uncheck the box to use hardware acceleration. More information in this support article from Adobe: http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_Solve_video_playback_issues
(3) Disable protected mode (Windows Vista and higher)
The protected mode feature of the Flash player plugin has security benefits, but seems to have compatibility issues on some systems. There is a hidden setting for this:
(A) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.
(B) In the search box above the list, type or paste flash and pause while the list is filtered
(C) Double-click the dom.ipc.plugins.flash.disable-protected-mode preference to switch its value from false to true.
This might not take effect until all Flash has been unloaded for a few minutes, or you close Firefox.
