Check out this video link; it proves that Mozilla Firefox continuously increases the size of memory consumed every moment..

What's the matter?

Does the same happen when you are not using flash? – Hennes Jul 22 '12 at 18:59

though my netbook is having only intel core 2 solo cpu @ 1.40GHz but check this out.. – Hari Om Jul 22 '12 at 19:26
Do other browsers do the same thing? – user3463 Jul 22 '12 at 21:36
-1 No, I don't want to check out a video. State your actual problem, which version of firefox you use and what addons you have installed. – Baarn Jul 22 '12 at 23:55

check your add ons and plugins disable them and see if it makes a difference. I installed a gmail plugin which took over 1 gb ram when active. CRazy :-(

Alternately, clear the download history (you may need to exit Firefox and delete the file downloads.rdf file from the profile folder in some cases [4]) and change your Download History settings to remove files from the Download Manager "Upon successful download" to circumvent the problem

more advance options would be to change the about:config preferences below while these may have an effect on memory consumption but may also affect performance or reduce functionality

Preference Max memory freed browser.cache.memory.capacity and browser.cache.memory.enable 14MB browser.sessionhistory.max_total_viewers

All the best
