Firefox 52.9 uses too much RAM

[erpster4]

I noticed that Opera does use a .exe for each tab that's open. Didn't check it for SeaMonkey.

that's because Seamonkey uses one "unified" EXE process and its not "multi-process" like with recent Chrome, Firefox & Opera versions
Seamonkey devs chose not to do a "multi-process" edition of it

Thanks for the explanation.

I've haven't done too much with this but I did notice that when I was at the Win 7 forum and let it sit, the memory usage crept up just like with my e-mail. I noticed that, like my e-mail which has ever changing ad images, that the Win 7 forum now has ad images so that may be issue. Trouble is, the ads don't seem to be cached by the browsers nor does the size of my Windows temporary files go up because of this..
