How to limit the number of tabs in Firefox?

Question

Mozilla Firefox

Hello.
When watching a video, I often scroll through the tabs, get distracted.
Please tell me, is there any way to limit the number of tabs to a certain value? However, I do not want to close the old ones. Is there a suitable extension?
