Hi, I have a Mac G4 Quik Silver (7450), 1.25 GHz processor and 2GB of RAM. I used the TFF version 38.10.0 and 45.4.0 but they after launch lock on the front page for about 1 minute and then reacts. These versions use too much CPU, see Figure 1, and the Mac is very slow.
Thank you

    Please click Help>Restart with Add-ons disabled and see if there's a difference. High processor load or even "locking" at startup is normal, but not for a whole minute. It should be max. 10 seconds on your G4 system. It's about 25 seconds on my very low-end G3 Pismo 400 MHz.

    You might also consider a profile reset, in case it's trying to clean up something corrupted and failing (see "How to reset your profile" at the lower right). On my 1GHz iMac G4 with 1.25GB of RAM, 45.4.0 comes up and is fully functional in about 10-15 seconds.

    Excuse my English language, I use google translator.

    Thanks for the answers, I have found the reason for the slowdown, the problem was the extension Adblock Plus, it was absorbing too much ram. I have changed with uBlock Origin and TenFourFox is good.
    My G4 is reborn!

    Your work is great.
    Thank you very much.
