Your insane memory usage is probably due to some plugin or other. Adblock is known to consume something like 40mb per tab open for example, due to injecting a large stylesheet into every single page ever opened.

Wow. Is there any way to mitigate that?

The only true fix is to remove it, although changing the ruleset and finding out which tab has humongous numbers of iframes is probably a good start: according to link 1 ABP has a static memory consumption of ~60MiB, plus 3~6MiB/iframe (since it's caused by the stylesheet size, I expect the precise ruleset impacts that)

  Don't use AdBlock, use the HOSTS file: http://winhelp2002.mvps.org/hosts.htm http://winhelp2002.mvps.org/hosts.htm

  Push for a Firefox port of HTTPSwitchboard.

> Adblock is known to consume something like 40mb per tab open for example Nope. It's more like 4 MiB per iframe. ABP is a well-written extension, and I am 99.9% certain that it is not the cause of a Firefox instance taking up 21 GB of memory. Please don't spread misinformation.

  Apologies, I definitely misremembered the facts and should have checked up on it. I wonder how many iframes the average page has though, especially given Facebook like buttons and similar widgets. And someone like me, who maintains hundreds of tabs, could easily take up a few gigabytes of memory per addon, even if the amount of memory used for a single frame isn't that high. I'm sure ABP was not the cause for the entire amount of memory in this case (or perhaps not at all), but many addons, each adding a bit of weight, can add up quickly.
