Massive Slowness (High CPU & RAM) with the new Quantum

Hi, Is there any solution on the way for this major problem? I've been through many many threads with the same issue since the last upgrade to Quantum and no solution for me and many other users

the new Quantum is choking the systems - I'm getting huge CPU and RAM peaks (i5 with 8GB of RAM - win 7 64-bit with 64-bit firefox) these spikes usually occurs when opening new tabs or on facebook (I have around 500 tabs opened but they are not in use simultaneously - only added through time) when more than 2 are being used its getting huge amounts of RAM and CPU spikes

I've checked the setting to prevent accessibility services

Under Options --> General --> Performance I unticked everything & changed the recommended size to 2

I added more Virtual memory as recommended

I replaced the addblocker to uBlock to save RAM

after all of the above there is no change, now this is not a 15 year old pc that I should experience this massive choke and instability (even if its not a new pc)

any suggestions on how to fix it? what's the percentage of users experiencing this after the upgrade?

anyway, thank you very much the amazing firefox over the years and I really appreciate what u created with this browser

Tabs open uses RAM don't fool yourself that they aren't. And that would tax the system 500 tabs is alot for a Browser to manage and maybe that is why it is taxing the RAM.

yeah I had a pretty high RAM usage before the update to quantum but not that unstable and unusable - the spikes are choking it & the high CPU as well
