Firefox freezes the system - the mouse barely moves
Re: Firefox freezes the system - the mouse barely moves
I would recommend you get more RAM which will help the speed of that computer since it's running an older CPU. I have a similar CPU in my laptop computer but I have 4 GB RAM which I plan on upgrading to 8 GB RAM. I run XFCE on that one. The other alternative is to try running XFCE or run ANTIX.
I am command line illiterate.
I copy & paste to the terminal. Liars, Wiseguys, Trolls, and those without manners will be added to my ignore list.

You can also install a good ad blocker extension for Firefox so it doesn't waste bandwidth and memory displaying those. I use Ublock Origin along with the antiX ad block thingy in the repo. And limit the number of open tabs. But a lighter browser in addition to those is also a good idea...maybe Pale Moon in addition to the other suggestions?
