Firefox 37.0.1 memory consumption spikes to over 3GB when loading/rendering ftp://ftp.vim.org/pub/vim/patches/7.4 (images->content/raster/used->source). CPU usage also spikes. Behavior borders on being a resource exhaustion DoS.
Firefox 36.0.4 renders without issues.
Tests done on new installs with vanilla profiles (i.e. no 3rd party extensions/plugins)

I'm not seeing that behavior on Firefox 40. It seems odd that there's so much memory being used for images just to display an FTP screen. Does it show any kind of images on the screen besides the little file icons?

Fixed in 38 already.

Thanks for the reply - I wouldn't have found bug 1148682 on my own.
According to some quick googling, FF 38 is due out 2015-05-12. Does that mean we'll see the fix back-ported to 37?

Unfortunately not; the fix for bug 1148682 came too late to make it into the FF 37 release. Sorry about that. =(
FF 38 is available as Firefox Beta right now, so you can use it today if you'd like.

Thanks. I actually meant 37.0.2 (or so) though back-ports are probably limited to egregious blockers and/or bugs with likely security implications.

Thanks for the report! We happened to have caught this one ourselves but there are plenty of memory issues that only happen some times and are hard to figure out without reports.
