Installed Firefox v43 great. No menu button the three dot symbol. The only way to access the menu is from the history tab after clearing the history. Psst: using a new private tab won't save your history. Clicking on that opens the menu. I can access the menu, but you can't use it while visiting websites. Any ideas. I don't want another version. I want to turn the menu on. On the Alcatel you can push the menu button and hold, but it only brings up a site list no menu or settings.
