Can you recall what significant change have you made to the system? |
| 35 |
For emerged packages you can try smth like genlop --list --date 1 |
| 36 |
month ago and then check against the versions upgraded from. |

You say swappiness is set to 0 but dont give any swap usage info. If |
| 45 |
there is any swap usage while swapiness is 0 then it would be weird |
| 46 |
and we could blame it on the kernel. |

I just googled mem usage firefox as I am running out of ideas. It seem |
| 49 |
like you are not the only one complaining about this. Take a look at |
| 50 |
these top results. There are some tweaking advice, see it they work |
| 51 |
for you. |

Chromium, which I have been happily using for almost a year now, has a |
| 56 |
task manager which shows mem usage of every extension and tab. If |
| 57 |
firefox has switched to multiprocessing, which was a feature plan some |
| 58 |
time ago, similar tool should likely be available for firefox as well. |
