Hi all,maybe it is just me,but Firefox tends to get stuck after a few minutes ,CPU on 100% ,especially when on twitter.
Anyone has any tip to minimise the use of resources of Firefox .Running on a 1.2Ghz ancient laptop wt 1GbRAM .
thanks in advance

This linked article is one of several in a series published to ghacks.net

Although the article is dated 2016, the list of suggested firefox custom preferences is continually updated and is available from github:

Typical question:"How do I use this?"
Read, read, READ (maybe a portion at a time, across several days) and understand"which settings affect WHAT"
then, via about:config in firefox, selectively change the preferences of interest to you.

I'm not a twitter user. The reference linked above is a general/comprehensive firefox"guide" that I respect & recommend.
Maybe someone reading this topic who is familiar with twitter can suggest a"surgical" tweak (or 3?) specific to twitter.

I have a faster machine than that, but was having similar problems especially with videos running 100% cpu from firefox, which were likely flash related. Sometimes I would get a script not responsive error. Anyway, this morning, from a root terminal I did

apt-get update && apt-get upgrade

and that seemed to end the 100% cpu problem. I guess I should caution that just because it solved my problem doesn't mean it will fix yours, and I've had problems before doing upgrades, but this time no problems here.

readout in your next post so members can see your specs. I am right now installing a3 stretch antix version on a old old Panasonic CF-48 and am going to post my results over here.

Edit: Since I have posted earlier. I downloaded Seamonkey and extracted the tar.bz2 into my /home/harry directory.

Code: Select all

harry@antix1:~
$ ls
clir     Documents  Icons            Music     screeny    Videos
Desktop  Downloads  LiveUSB-Storage  Pictures  seamonkey  Wallpapers
This is so I can run Seamonkey updater that is built into the browser
Help>Check for Updates

as a user without running Seamonkey in /opt and updating it using

Code: Select all

sudo /opt/seamonkey/seamonkey
My line for adding a launcher in my toolbar is made as follows ~/.icewm/toolbar

Code: Select all

prog"Seamonkey" /home/harry/seamonkey/chrome/icons/default/main-window.png /home/harry/seamonkey/seamonkey
Or you can drag and drop from inside the seamonkey folder"seamonkey" if using rox desktop to your desktop and it will stick as a launcher there. You can set the icon and grab it from where I grabbed mine for the toolbar showing in my launch command in the toolbar.

I only bring this up because I use SeaMonkey instead of Firefox on My IBM T23 which has a Pentium 3 , 1.2 GHZ processor. It runs a little lighter than firefox and is bearable on my Pentium 3 for certain tasks.
