Which Browser Will Perform Best For Any Potato PC?

Hello friends, I have been using Chrome for several years but recently it has been freezing a lot. It is likely because I use a low-end PC with the following specs: 4GB RAM, Core 2 Duo, and still running Windows 7. I want to move over to a low memory-consuming browser but I don’t know which one to use. Does anyone have any suggestions for a good low memory-consuming browser? Any suggestions will be appreciated.
