FireFox 34.0.5 hogs the memory

Since updating to this latest version and with only tab open, every time I run a page with flash I get a message from Windows within a couple of minutes saying it wants to close Firefox as I am getting low on memory.

This has never been an issue before and is not an issue if I use Chrome (which I would rather not), even with just this page open Firefox is using nearly 200mb of memory and Chrome is sitting on a page using Flash and its using 31mb of memory.

My system is not the most high powered but with 4gb of memory it shouldn't be running out of it with 1 tab of flash on Firefox.

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All of them.

Having more than one version of a program may cause issues.

Grab the uninstaller from here: Uninstall Flash Player | Windows Uninstall Flash Player | Mac Then reinstall the latest version.

Disabling all add ons made it come down to 167mb, re enabling all but chatzilla (which I don't really need) made it stay around that 167mb mark.

Guess when I play flash games I will have to use Chrome.
