Firefox memory leak? It doesn’t have one. Unfortunately, because of the way it’s configured to run out of the box it *looks* like it has one.
Follow these simple steps to get your Firefox memory usage under control.
These configuration changes are a trade-off between internet browsing speed and memory usage. They are most useful if you are multitasking and need Firefox to be less of a memory hog while using other applications.
#1: about:config
Type “about:config” into your address bar to access the hidden configuration options for Firefox.
#2: browser.cache.memory.capacity
Controls how much memory is used to cache pages.
Right click on the page and choose New then Integer and create an integer called browser.cache.memory.capacity and set it to a low number. This controls how many kilobytes of memory are used for the browser’s cache.
NOTE: number in screenshot is too small. Aim for 80% of whatever the default is.
#3: browser.cache.disk.capacity
Controls how much disk space is used to cache pages in kilobytes.
Set browser.cache.disk.capacity to between 5000 or 15000.
128MB to 512M -> 5000.
512BM to 1GB of RAM -> use 15000
#4: config.trim_on_minimize (optional)
Configure Firefox to swap memory to disk when minimized. This will make Firefox less responsive if you minimize/maximize a lot, but it is good if you need to free memory while multi-tasking to other applications.
Right click on the page and choose New then Boolean and create a boolean called config.trim_on_minimize and set it to true. Now when you minimize the window it will free up memory.
#5: network.prefetch-next
Network link prefetch will download all pages with the rel=”prefetch” tag. This uses up more memory than you would otherwise think.
Set network.prefetch-next to false.
#6: browser.sessionhistory.max_total_viewers
This controls how many pages of history are kept in the back/forward buttons. Lower the value to something acceptable. If you do not use back/forward often then you can set this very low.
Set browser.sessionhistory.max_total_viewers to a low number.

unfortunately none of the above is relevant to ff 3.08
Jerry, the latest version is FF 3.5.5
You should upgrade.
Can anyone recommend the well-priced IT automation software for a small IT service company like mine? Does anyone use Kaseya.com or GFI.com? How do they compare to these guys I found recently: N-able N-central desktop management
? What is your best take in cost vs performance among those three? I need a good advice please... Thanks in advance!
Thanks for posting this very helpful fix. I been looking for ways to reduce the memory on my FF browser for weeks and your advice was very helpful.
Once again, thanks.
I truly believe that we have reached the point where technology has become one with our lives, and I think it is safe to say that we have passed the point of no return in our relationship with technology.
I don't mean this in a bad way, of course! Ethical concerns aside... I just hope that as the price of memory decreases, the possibility of downloading our memories onto a digital medium becomes a true reality. It's a fantasy that I dream about almost every day.

I'm in a love/hate relationship with digital memory because of how prices are always,and I domean always dropping. I hate buying Micro SD Cards for my R4 / R4i at (what seems to be) a crazy bargain price only to see it become a whole lot cheaper a couple of weeks later.
