Iam a heavy user of Mozilla Firefox browser and its very hard for me to move from this browser to the other new ones, which is why whenever i use this browser i find that i have somewhere around 50 tabs open along with many different Add-on’s running in background which range from Gmail Manager, To-Do Lists, Page Rank, Alexa Rank checkup options etc. Hence the browser becomes a lot heavier and its very slow in loading, which is the reason its recommended to try out RamBack, a Add-on for Firefox Browser which can free up RAM Memory.
Once you install this tiny application which is of just 8kb, you will find a option on your Browser which Lets you clear internal Firefox caches. It can be found under the Tools Tab > Clear Caches.
In order to compare the results i noted down the stats of the currently running processes of my Laptop and then ran the ‘Clear caches’ option to see the results. There was a excellent boost in the performance on the Firefox Browser, after which it stopped hanging and also it was not taking much time whenever i needed to open a new tab or closed a already opened one.
