Hi

Do you have many tabs open or many add-ons installed in Firefox?

There are 9 active add-ons. There are 11 fixed tabs and 14 open tabs.

HI. Sadly I notice this too, but can cope with it. 8Gb RAM on my Raspberry Pi 5 64Gb µSD

I only have two tabs open, this and another static page from my own site. My site is really small, the whole thing is only hundreds of megs, so Fx is very demanding with even a blank page.

However the 7Gb you see ....hmm! is that RAM the table headers are not shown. You can see the RAM for my two pages is 1.2Gb

My Fx uses loads of virtual RAM that makes no sense to me, but ???

That's not enough.. I got up to 24 gigabytes!!!! This is with 30-40 tabs open. I use 3 more browsers periodically - none consumes so much RAM! It's already 8.5 gigabytes =(((

What happens if you open one tab in a new profile (no add-ons)?

The window is open in private mode. The rest are all closed at the time of the screenshot.
