Firefox is lagging: updates prevent jerking

If you keep Firefox up to date, you will eliminate most of the sources of error. The performance usually increases with every update.
Your operating system should also be up to date. Not only does Firefox run smoothly, but also other programs.
Add-ons also affect browser performance. You should therefore update them regularly. Old plugins are not optimized for the latest Firefox versions and therefore slow down.

Firefox stores data from websites in the form of cookies. After a while, a lot of data garbage accumulates, which you can easily remove. This also makes Firefox a little faster.
Firefox's safe mode lets you find add-ons and plugins that slow down the browser. If Firefox is running in secure as well as in normal mode, no optimization is necessary there.
If nothing helps, you can still reset Firefox. However, this deletes all data and settings in your browser.
