I am a complete numpty when it comes to tech stuff. Had a problem loading FB page yesterday after I did recent Big Sur update which eventually resolved itself. However when I was looking for solutions on Google I kept reading that the cache should be cleared regularly. I managed to find the cache but chickened out at deleting them all. TBH I wouldn't know what each cache folder holds. Do I just delete them or am I better getting a cache clean up software thingamajig? If so which one? Thank sin advance
