P2? Maybe P1? It sounds like under some circumstances we're retaining too many images. I don't know how common that is.
  • 1181127 - Core :: DOM: Service Workers - Implement service worker event handler spec changes for no-fetch optimization


P2. Seems like a solid improvement to avoid some of the impact of a new feature.

    mccr8, what do you think?

Maybe P2?
  • 1266915 - Core :: DOM - twitter leaks a lot of orphan nodes through window refresh


Sounds bad, but I don't know how common it is.

    mccr8, erahm, what do you think?

  • 1270298 - Firefox :: Untriaged - OOM crash on code.org tutorial running in a VM

P2? Seems less important due to the VM part.

  • 1272078 - Core :: DOM - Leak of dom/memory-file-data entries persists after disabling addon

P2? I don't know if this is just something triggered by an addon, or if the addon is doing something unusual.

  • 1273735 - Firefox :: Untriaged - Possible Memory Leak on Firefox

I dunno. P2? It seems like there's bad stuff here but I don't know if it is actionable.

  • 1277376 - Core :: DOM - twitter can leak overlay windows until all twitter tabs are closed


Sounds bad if Twitter is doing this frequently. P2? Maybe P1?

  • 1277397 - Core :: ImageLib - High memory usage triggered by a jpg

P2, this is a jpg generated by a fuzzer. It sounds bad but hopefully these kinds of images don't exist in the wild.
 
P2 I guess?

I don't know what is appropriate for leaks in a particular devtool.

  • 1279035 - Core :: DOM - Memory spike running the "DOM Modification" dromaeo test

Just leave this untriaged for now. It could be bad. It would be interesting to know if the spike is more reasonable without e10s.

This is mostly JS stuff. Can't do much unless we can do something very fancy with sharing memory across compartments.
