devilsadvocate So i turn on my laptop and click on Mozilla to start using the internet,for about 30 minutes its running smooth and great and fine,then it starts lagging miserably to the point it is almost unusable,if i close it,i can not open it again,it shows a message of something like "thus program is already running,close it first" so i have to open task manager and End the process Firefox.exe *32 which is the thing taking the most memory in my entire laptop. so i now monitor it,when i boot firefox fresh its memory is about 50k but it increases gradually as i use it,and it becomes unusable when it reaches 500K,then i have to repeat the cycle. how do i solve this and why is it happening anyway,its been happening the last couple of weeks,all of a sudden.
Gamer This because you're opening multiple websitea that demand a lot of processing such as youtube or flash based sites; OR sometimes it is because of one certain site Sometimes I the same thing from time to time reached 500 MB, but never had it sluggish. just close the browser and wait 5 - 10 sec then reload if a problem occurred, try accessing it using a different browser like chrome to see if problem persists.
