ff b57 memory leak youtube

[derekm]

When I run lots ( 20 or so ) tabs of youtube ( only one running ), memory usage creeps up as expected.

When I close all of the tabs of youtube, the memory usage does NOT go down.

I have a jpg of windows task manager showing firefox using 3.7GB of ram with firefox not running.

Are you running Firefox Nightly? According to the forum software you're running FF58.

It has since upgraded to 58b04

I am running the beta channel

It could be Bug 1386177 - Very high memory usage after watching many HTML5 movies on Firefox with uBlock Orgin, even after closing them all,
some users even reporting issue without any extensions.

Could be, I have those conditions.

someonje should try Adblock Plus an Disable Ubo to see if they get the same problem

Trying it now

Same effect with Adblock Plus, won't release memory.

so that rules that out that its a Extension issue. looks like its a Browser problem, an i thought firefox Memory was supposed to be better handled from 57 onwards .

Only way to tell for sure would be a new Clean empty profile

[derekm]

I can do that

I can do that

have doubts it'll make any difference.
