good time of day, broke hard, all the old data on it did backup, how to restore data in the browser from backup ,? tk all the working information was in the browser, or anything not stored separately

First, how did you store the data? We need to know before we begin.

Во-первых, как вы сохранили данные? Нам нужно знать, прежде чем мы начнем.

когда удалял мазилу предлогалось сохранить данные ,и появлялась папка с файлами от браузера

Look on your desktop. Do you see a folder called; Old Firefox?
