My Firefox seems to be getting very laggy lately and this used to happen on my older computer when I was low on memory, however I checked and I have plenty of memory still available but it's still laggy, so I'm wondering do I perhaps have to increase the memory it's allowed to use?
By laggy I mean it has the same visual effect as lag, in that when you're interacting with the screen things "lag" / get stuck / appear slow - nothing to do with page load time.
I did a little digging and found this almost 12 year old thread; so I'm wondering does what is mentioned there still apply now?
Namely, by going to
about:config in the address bar and then adding the configuration setting
browser.cache.memory.capacity and giving it a value of the amount of memory it's allowed to use in Kb's?
If not, is there a way to do this?
