Hello,

On which web sites do you observing this?

How many tabs are in use?

What is the CPU?

How much memory?

Can you test with JS disabled?

The Firefox settings panel does not include an option to disable JavaScript but you can still disable it using the Firefox Configuration Editor:

about:config

  1. In the address bar, type about:config and press Enter.
  2. Click "I accept the risk!"
  3. In the search bar, search for "javascript.enabled" (with no quotes).
  4. Right click the result named "javascript.enabled" and click "Toggle". JavaScript is now disabled.

To Re-enable JavaScript, repeat those steps.

Thank you and I hope this helps!
