User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:57.0) Gecko/20100101 Firefox/57.0
Build ID: 20171128222554

Steps to reproduce:

I am simply using firefox as a browser and I am surfing from ebay to other web sites....
Press, pictures, etc.... Nothing special.


Actual results:

I have a look on the web-site cache and I noticed that the memroy size was growing rapidly to 350 MB. As the limit of 350 MB was reached firefox was froozing the complet computer!


Expected results:

I am awaiting that the cache memory is emptied at each opening of a the next web site or picture

Thanks for the report.  We already have a report like this, Michal do you remember the number and state?

It's bug 832157, so far we weren't able to find anything in the logs from the reporters.

Francois, do you see the same behavior with smaller max cache size, let's say 20MB?

Are you able to provide log of a moment when Firefox fills the cache and becomes slow? See https://developer.mozilla.org/en-US/docs/Mozilla/Debugging/HTTP_logging, MOZ_LOG should include cache2:5 module.

Maybe also profiler could give us some useful information (see https://developer.mozilla.org/en-US/docs/Mozilla/Performance/Reporting_a_Performance_Problem). If you're able to get the profiles, generate one profile of loading several pages when the Firefox is fast and then another profile of loading the same set of pages when it's slow.
