Want to stop Firefox to display the thumbnails of Web sites visited previously when click on new tab

Since I use my computer for work and personal activity, and I do a lot of online meetings, it's a distraction and not professional to have a bunch of Web site thumbnails appears if I happen to need to open a new window while sharing my screen. There is a reason that I stopped using Chrome ad, now I see that it is a problem with Firefox.

If you want to disable the thumbnails on the subject: newtab page and then create a new pref Boolean browser.pagethumbnails.capturing_disabled on the topic: config page and set to true.

You can open the topic: config page via the address bar.
You can accept the warning and click on "I'll be careful" to continue.

Delete the folder of thumbnails in the Firefox profile folder to remove the thumbnails already memorized web page.

You can use this button to go to the current Firefox profile folder:
