I have a problem with Firefox since I can't remember when. What I do know is that I love to open a lot of webpages and place them in tabs. But lately, I find that the Fox jerks. What I mean is, that when I start to scroll the pages, I have to wait for more than 5 seconds at least before it allows me to continue. And when I type text, especially when I made mistakes, the cursor would not move for at least 10 seconds or even, I can see the text coming out one by one every few seconds.
Naturally, I though it has something to do with my Notebook since its more than 8 years old. But dang it, this Toshiba Tecra 9000 lasts and lasts. (Or until there are no spare parts?). And so, one fine day, I got to this site from a Forum.
It tells you the main reason why Firefox 3.5.x suffers from slow speed. And here is the solution:
1) Goto the Firefox address bar and type: about:config
2) You will be shown this screen. Just be careful lor.
3) Under the filter bar, type: browser.cache.
4) Locate this line and double-click the TRUE statement to change it to FALSE.
5) Restart Firefox
Bear in mind, if you do not know what you're doing (like me) and feel lucky (not like me), do not attempt to do this. Because the result might not work for you. But for me, its as if my Notebook;s burden has been lifted.
