G3 + TFF - speed and ram problems

is there any solution to fasten the actual TFF on G3 iBooks?
I had a test on an Clamshell with Tiger installed and it was note useable, because TFF took 80% of the cpu and the RAM wasn't enough (SWAP).

    Hey Christoph, I use TFF on a 400 MHz G3 Pismo with 1 GB RAM. It's pretty
    usable there. The thing is: You need enough RAM (512 MB is the bare
    minimum), and this is even more vital if the HD and the processor are slow.
    I'd say 1 GB or more is recommended. Also, you need to wait a minute after
    the browser is started (look at the processor time in Activity Monitor)
    because it takes a while to load completely in the background and will only
    then be usable at full speed. In the realm of Clamshell iBooks (300/466 MHz
    max.) 'full speed' still won't be very impressive, though.

    Hey Chris

    thanks for your fast reply.
    The iBook is very limited and i have only 544MB RAM.
    I checked some speed up instructions I found on the web but TFF won't become really useable.
    I turned of some things.

    Are there any other optimizations which can be preset in the G3-Version?
    Is it possible (don't know how) to set the TFF to only surf mobile websites like Classilla without an add on?

    It will be possible in 45.8, hopefully.

    Chris is right, though: 544MB is not nearly enough to run the browser well, unfortunately. The JavaScript compiler needs a lot of memory to work effectively.

    But that means not that TFF with mobile user agent is faster than today?

    I really would like to find a solution to surf with that old machine.

    TenFourFox, as fast as its JS engine may be, can only do so much to compensate for G3s in the 400 MHz range when trying to browse websites like Facebook that keep adding more JavaScript nonsense on a daily basis.

    The biggest problem with clamshell iBooks is RAM. Since you can't add more on these beautiful machines, you're out of luck here. The situation can, however, be mitigated:

    Disable JavaScript (using the NoScript or - better - YesScript add-on) on all sites that don't absolutely need it, this helps a lot. Use a lightweight adblocker like uBlock to get rid of non-essential parts of the website. Try mobile sites as often as you can. Close all other apps when using the browser to make as much RAM available as possible. Open one window only with two or three tabs maximum. And most importantly: Be patient and keep in mind that this computer is 16-17 years old.
