M1 Macbook Air - Webpage reloaded due to using significant memory

I have a 2020 M1 Macbook air 8gb ram and will have very minimal apps open and only one or two tabs and will still get the message that ‘closing this webpage may improve the responsiveness of your mac’ and then the webpage will automatically refresh. This is very annoying when watching lectures and recorded zoom meetings as it restarts the meeting and I lose where I was up to, any suggestions on how to fix this. I have attached a photo of my activity monitor when the message came up and I’m not enough of a Guru to understand what this all means
