Firemin 0.3.6.369 - optimize Firefox memory usage

Firemin is a small app that eliminates all memory leaks in Firefox and keeps memory consumption at bay. The program runs in the system tray and constantly optimizes Firefox's memory by forcing it to release some of the memory it so greedily hangs on to. Firemin uses a save Microsoft API (EmptyWorkingSet) to force Firefox to release some of the reserved memory without causing stability problems.

There are similar “Firefox memory boosters” available; however, most of them are frauds (work mostly contain spyware and malware) or work using the Placebo function (if you think it will work, it will). Firemin does not contain any malware and actually do decrease Firefox memory usage, up to 95% (under 1MB in some cases). Even though Mozilla keeps claiming that they fixed their memory-leaking issues, it seems like this is not completely true. Maybe one day, but until then, Firemin will lend a friendly hand.

Firemin is a very simple utility and, for this reason, does not demand any installation utility. Simply unzip all files to any folder and run the executable file (usually, "Firemin.exe").

What's new in this version:
- Removed the update option because the Firemin server was getting a little overloaded.

Firefox was at it's worst in terms of memory usage in the Firefox v4-6 days as once Firefox v7+ came out it fixed a big chunk of it's memory consumption problems and it was noticeable to by looking at memory usage in Task Manager etc.

even with my recent system upgrade, which has 8GB of RAM, i typically never see my memory usage go more than 500-600MB and i am currently at 628MB with 16 tabs open on Pale Moon x64 v12.1 (which is basically the same as Firefox but 64bit).

Haven't seen a leak in FireFox itself since like version 4. Last one I've run into was a bad addon a few versions back, long since fixed. My installation is typically active for days without restart, and usually hovers at ~250MB or so, and that's with a bunch of addons. (Wish I could say the same for Chrome.. hopefully they'll do something about that memory hog one of these days.)

Besides, calling EmptyWorkingSet isn't optimizing anything, and if anything is going to slow it down as it has to page all that stuff back into working memory when it needs it.

Same here. A lot of people claim "memory leaks", when in reality most of it's just Firefox caching stuff (and it does cache a lot of stuff). That's not to say it's free of leaks, and extensions shouldn't be allowed to leak memory either, but it's not as bad as people claim it is.

My guess is that this tool is mostly snake oil, and likely does more harm than good.

I was sticking to firefox, but latest adblockers for chrome does the job for me. I am afraid, that more and more will switch to chrome
