So you kinda have to buy a new computer unless you want to struggle and keep Firefox at version 5.3

I hear you, although i run FF 19 with about 80-110+ tabs open (i try to get back to them) , and OpenOffice with about 15 docs open for more editing, and Thunderbird with multiple email accounts, using a 2005 Sony PC with 2.8ghz 64bit dual core cpu, and 4gb ram and a flash drive using ReadyBoost under W/8 pro 64bit.

However, the Intel mobo will not allow more than 3.38 gb or ram to be available, which i did not know when i upgraded from XP32 bit for 29.00. So i usually have about 1gb of free ram (and a page file on a separate drive)

FF used to use a lot of cpu cycles (and after restarting it i have almost all my free ram back) until i install the NoScript extension. Sites like Amazon send it up.

The most tabs I have open is 60. You may? know you can get the “session manager” extension which allows you to crash Firefox via task manager (control+shift+escape) then recover exactly what you crashed. This strips off the bloated memory usage until the next time you repeat.
