very useful thing ! thanks again
If your using Firefox and noticed it's been a bit slow lately, might I suggest that you try these settings that are more like Firefox 2.
Enter "about:config" in the search bar without the quotes.
Confirm you wish to edit Firefox settings...
Search for these settings and change them to the new values.
Remember this is for users on low-bandwidth such as those with dial-up modems. If it doesn't improve your connection, set them back how they were originally ~(remember to write them down).
Good luck! :o)
