Is this update from Firefox?

Question

Browsers

Good afternoon. Each time you turn it on, this update warning from Firefox pops up. But there are doubts that this is not firefox joxi.ru/12MDdnwI4MJlqm . When you enter the browser, it has already been updated, and this window still pops up. Don't know what it is?
