Most Windows applications let you open files on the disk. They use a set of menu conventions that have been around since at least windows 3.0 back in the early 90s. What does MOZILLA do? Oh, lets throw all of that out the Window (pun intended) and leave you this vestige "Firefox" tab that you can pull down a tiny minority of those menu item.
So back to my original question: Where the fuck is the FILE-> OPEN menu?
I want to check a file on the hard disk attached to my PC. Guess what? I can't Maybe you made the menu so blindingly obvious that a software engineer with 30 years of programming experience like me just can't see the forest for all those pesky trees. I have no clue. So am I supposed to put the path into my URL window? That's easier than "File -> Open?" WTF Mozilla?
Now, why do you have to dig around on a forum like this to find this out, and why are the menus turned off by default?
Mozilla is not alone in this lunacy. Microsoft Office did the same thing with their 2007 version, breaking the paradigm that had served us well (or equally badly?) since the early 90s. I guess Mozilla had to follow suit.
