web browser activity

it is something related to memory leaks and is most prevalent in firefox. it basically is that, once a portion of ram is used by the browser application, it is unable to empty the memory blocks after its work has been over. Thus the ram get loaded up and makes the computer slow.

Now the thing is that this problem will be observable in the browser as well as the computer if the overall ram of computer is (generally) 1 GB or less. For systems with more amount of ram than that, it will cause a slow up of the browser only, or atleast so is my observation regarding this case. This sometimes escalates more if one has browsed through heavy media items such as lots of images and videos and then put the browser up for long. Long browsing (usually hours) of heavy stuff along with operationg of too many multiple tabs (I usually tend to have more than 25-30) and many addons and bookmarks will bring up this problem even sooner.

the latest firefox is better than before but still will give you the problem and engineers there are fighting hard to overcome this. Opera and Chrome are much better in this respect.

it can be related to memory issues.
somethimes when we not use a task for a long time it get removed from the RAM due less availabilty of space hence it can take time to respond and also sometimes may not respond because it may be aborted by other procces.
