User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:17.0) Gecko/20100101 Firefox/17.0 Build ID: 20121128204232 Steps to reproduce: Use this site with example... http://mpdrolet.tumblr.com/archive Rolls this site until you reach october... Actual results: Firefox starts to "spike" and goes slow after they reach 300 ~ 400 MB of ram. When you reach october firefox will using 900MB of ram.
Did this start with Firefox 17? Or did you just spot it now?

It's an old behavior with webpages displaying a huge quantity of images or thumbnails like galleries for instance. Just open about:memory?verbose in the location bar, you should see an important memory compartment for image decoding.
(In reply to Virgil Dicu [:virgil] [QA] from comment #1) > Did this start with Firefox 17? Or did you just spot it now? Later I will install all old versions and test, to provide a best report... But it appears to worsens every build...
Flags: needinfo?(leandrocostabh)
about:memory info FF 17.0.1 I don't now the precision of this information... When I open a new tab to view the memory usage firefox drops lot of memory usage... With active tab (with images) firefox consumes 800mb of ram. When I a open a new tab to view about:memory page it drops to 250mb too fast... I don't care about memory consume, but the "lags" to change tabs (minimize and restore window) with too much images is annoying...

It's a normal behavior, Firefox discards the images from memory when you switch to another tab to reduce the footprint. Anyway, keep in mind decoding images uses a lot of memory.
Tested all versions. 4.0.1, 5.0.1, 6.0.2, 7.0.1 changing tabs (with images) have no "lag"... 8.0.1, 9.0.1, 10.0.1, 11.0, 12.0, 13.0.1, 14.0.1, 15.0.1, 16.0.2 and 17.0.1 all have the problem... all versions get slow after a certain quantity of images loaded... (normal? needs to improve) Thing I observed is: After lot of images loaded firefox hangs when need to download and render more images... why? (insufficient memory? not my case... I have 16GB)

Waiting bug 689623 solution... something good will come out of here.
While testing this on the latest Nightly, I can see indeed that while scrolling down to October images, the process seems pretty slow. User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:20.0) Gecko/20121217 Firefox/20.0 Build ID: 20121217030850

Thank you Manoj and Tom for the help! I tried to get a profile, but Nightly kept on becoming unresponsive and I was unsuccessful.
Bug 689623 will probably fix the memory consumption aspect. Off-thread image decoding might help with the lag.

I see similar numbers. Enough to declare victory, IMO.
