Running out of memory
I have a 2020 MacBook Air, 1.2GHz, 8GB of RAM. Among many problems, I am constantly being alerted by CleanMyMac that I'm running out of memory. I know things run in the background, but at the moment I have 2 tabs open in Firefox (including this one) and no other programs running in the foreground and my available memory is about 170MB. I have run through a list of the suggested Firefox suggestions to reduce memory usage, and I have restarted my laptop and cleared cache. Any suggestions (apart from switching back to Safari - please)?
If needed, I can specify more info from the Activity Monitor, or otherwise.
Thanks in advance!
