Hi, I'm seeing near constant 30-40% CPU usage and ~1GB memory usage by the browser chrome process, and ~20% CPU but ok memoray usage by one of my (7) content processes. I'm on Nightly 61.0a1 (2018-04-24) (oldish Nightly because I'm nearly out of bandwidth so I can't afford updating and reloading all of my tabs at the moment). I recorded a performance profile: Could somebody tell me what's consuming CPU? Thanks.

Hi, using a nightly build or beta does not help much.

Please Copy/Paste about:preferences#privacy to the Address Bar then Enter.

Go down to Permissions and the last one please make sure there is a Check Mark in the box to prevent accessibility services from using your system.

Your Extensions take aprox give or take 20megs each so there goes a gig. Plus all of them updating and taking and stuff is bandwidth.

use a ip or port scanner to determine what is using bandwidth. Do a scan with and with as both scan differently.
