Firefox 12.0 fresh install uses 919 MB of memory within 5 minutes.
Firefox started to take up too much memory since a month back. Just recently I installed version 12.0 and it still uses crazy amount of memory.
Much appreciated if you can share any fixes or solution for this issue.

Check and tell if its working.
Checked those articles and they're not helping. Do take a look at the screencast. Disabled most of the plugins and all extensions. No extra theme either.
Just opening up Firefox alone and leave it for 5 minutes will still take 900 MB.
If you use about:memory you will see exactly what is using the memory, and have buttons to reduce memory use. To do that all you need do is type about:memory into the location bar and hit return.
If you open Firefox in safe mode on a blank tab it will probably not use anything like 900MB try it and see what happens. Then try more normal use a step at a time and compare the results.
Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":
If the new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.
