"calaccessd" and "suggestd" using almost all of my CPU!

Hello,

The last weeks I have gotten the "your system has ran out of application memory" message. Only using Firefox. Firefox is using under 1GB, but a process called "calaccessd" is using almost 4GB and "suggestd" is usint 1 GB. Then there are several other firefox processes.

None other apps are open, none are running in the background, I have restarted my macbook. I am updating now to Sequinoia to try and help. But does anyone have any tips here?
