Question about SSD

maybe but i think (i dont know exactly) your internet connection is more important

No, that would be related to your internet speed.

If you mean total refresh (redownload of whole cache) then prolly will have minimal if any effect. But if you let browser use bigger files catched on drive, you might see some difference,

Imo ssd is not worth just for it.

Unless your internet is google fiber fast, then i have no idea, it just might.

yup won't help much other than starting faster ... but load times and whatever likely to have no "visible" difference
~ and about the same, since most data of the browser gets temporarily stored in your RAM
