User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:61.0) Gecko/20100101 Firefox/61.0 Steps to reproduce: I started firefox on 21 Aug. Now, after month and a half of running, firefox consumes 12.8G of virtual memory and 3.9G of RSS. I don't know if that is normal, but to me it looks like too much. I am attaching a memory report. The number of tabs is approximately the same as when started. Over that time, the responsiveness is decreasing too. I don't know if that is related to the memory pressure or not. Here is the perf profile: https://perfht.ml/2yeb83g Running with a new profile or without add-ons for such a long time to test this is not much of option. So I hope the memory and perf measurements can pinpoint the problem. Actual results: For example writing into the address bar or to this text box does not show characters as I am typing, but later in batches. Expected results: Fluent behaviour.
Hello Mike, can you please take a look into the profile? Thanks!
Definitely the memory usage is related to the sluggish behaviour - looking at the profile, I see the parent struggling to cycle and garbage collect to try to free up space. That's taking cycles from the main threads. I suspect there might be a leak here in AdBlock Plus (or in the APIs it's using)... jiri, if you switch (temporarily) to using uBlock Origin, do you see the same behaviour?

That's taking cycles from the main threads. Which reminds me that "Minimize memory usage" did not lower the memory usage at all. That makes sense. > I suspect there might be a leak here in AdBlock Plus (or in the APIs it's > using)... > > jiri, if you switch (temporarily) to using uBlock Origin, do you see the > same behaviour? Switched to ublock, now give me ~ 2 weeks to reproduce :).
(In reply to jiri slaby from comment #4) > Switched to ublock, now give me ~ 2 weeks to reproduce :). I had to reboot yesterday and forgot to take a look on the memory consumption. The feeling (responsiveness) was good though.
It looks promising with uBlock. It is running since 19 Oct, and the 5 firefox threads eat each 500-700MB of resident memory. So what next? (I keep it running.)
Hey evilpie, do you know if there's a tracking bug for ABP memory bugs?
