Well i decided to uninstall the app, copying down all my bookmarks first. Then i reinstalled it. I chose to install it from the list of apps i used to have installed and that actually installed the previos version. I thought of just staying with that but i got the message that an update is available so i updated it again and now it doesn't crash. Unfortunately i had to re enter all my bokkmarks and all my saved passwords again. And i still have to deal with all the horrible changes. But it doesn't crash at settings anymore.
Thanks
