User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:109.0) Gecko/20100101 Firefox/117.0

Steps to reproduce:

I opened a single window on OSX and noticed that RAM usage was quite high. Gets even higher as I open multiple tabs/windows

Actual results:

RAM usage was 1+ GB. See memory report.

Expected results:

RAM usage should be closer to the range of other browsers ~300-600 MB
