Good Morning everyone,

I use Firefox 84.0.2 (64 bit) on Lubuntu 18.04.3. I use it to manage blogs with Wordpress and the backend editor of Wordpress it’s laggy and slow.

Do you have any suggestion to speed up Firefox on my laptop? Here’s the specs of My PC ASUS S56C

Processor : Intel® Core™ i5-3317U CPU @ 1.70GHz Memory : 3922MB (1208MB used) Machine Type : Notebook Operating System : Ubuntu 18.04.5 LTS Resolution : 1366x768 pixels OpenGL Renderer : (Unknown) X11 Vendor : The X.Org Foundation -SCSI Disks- ATA Samsung SSD 840 ATA SanDisk SSD U100 MATSHITA DVD-RAM UJ8C2 S Kernel : Linux 4.15.0-130-generic (x86_64) Version : #134-Ubuntu SMP Tue Jan 5 20:46:26 UTC 2021 C Library : GNU C Library / (Ubuntu GLIBC 2.27-3ubuntu1.4) 2.27

Thank you in advance to everybody.

    Some who know more will probably chime in, but in the meantime here’s a couple things I would try, seeing as you still have a fair amount of free memory:

    • check if you are swapping for some reason (probably not): free -hw will show this. if so, try decreasing swappiness
    • tweak the number of processes under firefox performance preferences (default is use recommended)
    • make sure your ssd is getting trimmed ( look up fstrim service)
    • of course clear cache etc
    • if you have addons, create a new profile with no extensions and compare

    I noticed a huge speed increase when I set privacy.firstparty.isolate to true in about:config. This might only be an option in Nightly, however.
