firefox 66 how can i limit the disk cache?

[mantra]

Hi
i 'm running Version 66.0.5 under w10 and high sierra
i would like to limit the disk cache , i guess i have to enter in about:config because in the older version i could setup in the preferences (i guess in the older version was in browser.cache.disk.capacity )

how can i limit the disk cache to 350MB for example on firefox 66?
thanks

browser.cache.disk.capacity still exists in Firefox 66.0.5 You have to enter the value you want in kilobytes. I have adjusted that setting myself and it works fine. That said, I'm on Win7 but I doubt that matters. http://kb.mozillazine.org/Browser.cache.disk.capacity

350 MB = 358400 KB

is the only way to do it?
why do they remove from the options ?
and is there a extension that can do it ?
thanks

I had to disable browser.cache.disk.smart_size.enabled in addition to the entry BuddhaNature mentioned. I can't find an addon that will do it.

I'm on Win7 also. It wouldn't work for me until I disabled browser.cache.disk.smart_size.enabled; YMMV I suppose.

I'm not sure I'm following this now.

mantra, are you saying you can't find the preference browser.cache.disk.capacity in you FF?
I would also note that the mozillaZine Knowledge Base article I linked to said that for the browser.cache.disk.capacity preference to have an effect the preference browser.cache.disk.enable must be set to true (which it is in my FF).

I would also note that in my FF browser.cache.disk.smart_size.enabled is set to true and that is the default setting (I never at any time modified it myself).

If it was me with the issue and I couldn't find browser.cache.disk.capacity then for experimental purposes I would just create it myself as an integer preference, reboot FF, and see how it goes from there.

I found one article on why Mozilla commenting on why removed the setting from Options. Said the following:

Mozilla is going to remove this option as restricting the cache space may slow down browser performance and Firefox can automatically reduce its usage if you are low on disk space. So you don't need to worry about it.

firefox is limiting disk cache space according real disk space, we had that last days here. you cant control it unless disabling it at all, which makes no sense because cache makes firefox fast. it has no gain to reload any file from web. and as Buddha noted it will be disabled for reason.
