i use adblock plus 2.7.2 and firefox 46.0
a week ago I could listen to music even for a few hours and memory consumption was 350-500 MB, but now after a few ten minutes is up 1700 MB. if I disable ad blocking problem does not occur

[smed79]

1- reset firefox https://support.mozilla.org/kb/reset-fi ... t-problems

Disregard the irrelevant and unhelpful suggestion to change whatever blocker you are using -- investigating the actual issue is what actually help.

The issue is obviously the site's own script dealing badly with the blocking of some resources. Can you try the following exception filters and see if this help?

@@||newrelic.com^$third-party,domain=play.spotify.com
@@||nr-data.net^$third-party,domain=play.spotify.com

I still need to investigate more, to see if this can be further narrowed, but profiling memory usage shows that the page ends up growing an array indefinitely, it was almost 300,000 items and probably still growing after a few minutes.

If using uBlock Origin, force an update of filter lists, I added the two above exception filters to uBlock filters -- unbreak. Formal issue at https://github.com/uBlockOrigin/uAssets/issues/36.

Maybe this was the culprit: https://hg.adblockplus.org/easylist/rev/bf52fa108634 Please update EasyList manually and check.

If you are using uBO, I pushed a fix which does not require these two exception filters. Remove them and force an update of uBO's filter list. See if this works on your side.

Yes it works. I checked now with uBlock Origin. I listened music on spotify for one hour I not opened any other site and firefox.exe memory goes only to 355MB. it's amazing Now I will only use uBlock Origin. Thanks.
I see in the logger thats newrelic it's not whitelisted anymore, but I dont see any info about that script injection.
