I have seen it for about the last month or 2. It seems to have a limit as no matter how long it is up it won't eat up all of the ram on my 32gb machine, but it happily overruns at 10GB machien quickly I did a bit of looking and this might help (crudely pasted) (content limit defaults to 8, and lowering it reduces the extra threads+ram per firefox instance). You might try 4. I am going to have to try it on my machine with 10GB or I just have to give up and buy a new machine that I can get ram for. preferences -> home -> deselect use recommended peformance settings and more options will show up. Performance Use recommended performance settings (deselect this) Content process limit 8 Additional content processes can improve performance when using multiple tabs, but will also use more memory.
