    I don't watch video but just surf the web using Firefox. Yet, my MBP 2010 17"'s fan is very loud.
    According to the activity monitory, Firefox takes 70-150%CPU. Is this a problem with Firefox or my machine?

    Had this problem with Firefox often. I don't think it's been particularly well optimised for the Mac. I have since switched to Safari which works far better with less overheating. Give it a try.

    Firefox is a resource hog. Just use Safari, and you will be ok.
    But also, did you ever open up your laptop and cleaned it? You should do that, and even changing cpu paste would do great things to a laptop that old.

    Fire fox may be using hardware acceleration which causes the Macbook to switch from using the Intel video to nvidia gpu. The nVidia GPU generates more heat.

    Thanks. Over 10 years ago, Firefox was the recommended browser for the Mac. So, the situation has changed?

    I got lots of bookmarks under Firefox and some under Safari. I guess some have the same names. What can I do if I want to move all the bookmarks from FF to Safari without messing everything up.

    I know how to export but I am concerned about messing up everything when the bookmark folders in FireFox and Safari have the same name. I am also concerned that they overwrite each other.
