Open new window will run out of memory #164

Open OwenChia opened 8 years ago

OwenChia commented 8 years ago

Every time when I try to open a new window, it will run out of memory and then get killed. I had to disable this, how to fix this? I'm running Firefox 46.0 on Gentoo amd64, the DE is KDE 5.

Can not reproduce on FF 46.0.1, Ubuntu + Unity. Did you try reproducing the issue with a clean profile and just pentadactyl enabled?

@phanimahesh Can not reproduce with clean profile. I have 170 tabs opend, maybe there are too many tabs?

phanimahesh commented 8 years ago

Possible. Each loaded tab can take upto a few MB depending on the page and plugins you have. At 170 tabs, about 2G RAM is not a bad estimate. New window takes up way more memory than a new tab, since a new window is a new process.

I have 6G memory and 6G swap, and just opened only one new window, there are takes up too many memory.

Firstly, my estimate of 2GB was infact bad. Looks like FF takes much more RAM than I expected. Still 6+6 is a very large number, and this should not happen. Since you can not repro with a clean profile, the next logical step is to enable addons/plugins one by one in a clean profile and trying to repro. You should be able to arrive at a minimal configuration with which this can be reproduced.

As a quick check, is this issue reproducible with all addons except pentadactyl enabled? With all addons enabled but just a few tabs open?
