Status: UNCONFIRMED

Description

[[e-mail]]

Attachment: memory-report.json.gz

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:105.0) Gecko/20100101 Firefox/105.0

Steps to reproduce:

Opened more than 5 tabs on my firefox browser on my mac.

Actual results:

Firefox and firefoxCP isolated Web Content Helpers started to use combined up to about 4-5 gb of ram in some occasions, and it does seem to scale with the number of tabs I have open. I am wondering if this will happen

Expected results:

Firefox consumes up to 4gb of my 16 gb ram usages with it's firefoxCP isolated Web Content Helpers.
