Firefox has gotten to be a real memory hog
I am sure most any user of Firefox has noticed in the last few months that it has gotten to be a real
memory hog. I have been looking for ways to decrease memory usage and release old memory and came across a new one on me that I want to share with whoever else has not heard of it but has memory bloat problems from the application. enter "about:memory" in the same way you would enter "about:config" click on "minimize memory usage". A rollover will disclose what it does.

I haven't yet tried the newer FF versions, but there are things you can adjust, while checking memory:about won't tell you much that's actually useful. In addition there's the obvious solution of paying attention. If you have 10+ tabs/windows open you have no reason to be surprised they're hogging RAM. * Cache size. The majority of webpages therse days are of no value cached because most are generated dynamically. That means your browser will rarely be told that its cached version is as new as the current version because the current version is always brand new, even if it hasn't changed in 2 years. But if you allow a big cache then FF needs to manage it and search it with every page you visit. I allow 10-20 MB cache. * Super cookies. FF calls it "offline user data". If you frequent a site that needs up to 100 MB space on your disk then you need this. I remember Vanguard LH once said he needs it for an online game he uses. I've never enabled any offline storage and never needed it. But if it's enabled, sites may use it whether they need it or not. And why not? It allows them to use your resources to spy on you. (Look for "dom.storage" and "offline-apps" prefs.) * Prefetch - Disable all prefetch options. Prefetch means that FF will load links on pages you visit in the background, so it can appear to be very fast if you decide to click on one of those links. (I'm not kidding. It really does that! There's also DNS prefetch, typically used to look up advertiser IPs as a webpage loads.) Prefetch is a ridiculous waste and also a privacy intrusion. It's allowing all sorts of sites to monitor you and run script while you actually don't even know those sites exist. DNS prefetch and webpage prefetch can also be prompted by the webpage itself, if you allow it. * Number of connections - I don't actually know whether this will save on RAM, but it could be tested by setting a low limit on the number of concurrent connections. Like prefetch, there are several pref settings involved. * accessibility.blockautorefresh - This will stop pages from updating periodically without asking. * sessionstore - Do you want FF to load all of your open pages if it crashes? Then you'll want this. If you're not worried about that you can save RAM by disabling Session Restore. These settings get into a lot of nitty gritty detail. You may not want to go to so much trouble. But you should know this is only going to get worse as the Internet becomes more commercialized and ever more websites try to control what you see and do.
