So, I had this problem after update that firefory did not want to start. So I installed manually the new version of it, several times it solved the problem, but now it didn't. So I downloaded chrome, exported all my bookmarks, cookies, history and stuff, and after that I fully uninstalled firefox, and installed it again, now it did start. After that, I exported my data from chrome (what is exported from firefox) but it exported only these sites what was loaded in chrome.. So it means I have been saving my history since the start of the year, but firefox exported only these sites what I've been visited in chrome. It means only mozzilla.org. I think this is because it was not opened on chrome ever. But it saved all my history down. I've searched for it in the chrome's folder, and all the history is in it, because it's 12 MB big. I just don't how to export it. I know there is and option that allows you to export html files, the problem is this history file is not a .html file. So my question is: how should I do it?
