Hubspot RAM Issue with Firefox

Hello, I am currently using Hubspot in Firefox, and I have just one single tab open, and Firefox is using somewhere between 5GB to 7GB of Memory on my task manager. The website barely even works, and is so slow to use.

I have seen some other threads mentioning to try disabling extensions, try clearing cache, etc. I have done all of those tips, and still have not seen any improvement on RAM usage. The only website that seems to create an issue with it is in Hubspot, everything else seems fine.

Is there anything I can do to make this work better and more efficiently? I am tired of waiting 2 minutes for the page to load every time I want to try and update something in a contact.
