Re: Flashes when open things

That might just be Firefox. It first presents its UI stuff in the size of how its window looked like when it closed the last time, then it hangs for a bit and does not react to the window manager showing the window at a changed size. It fills the whole window only after it wakes up again.

I know that hang when it loads gets shorter if you have a new, empty profile without bookmarks, history, less tabs getting reloaded, so I'm guessing the hang is happening when Firefox works through its history database, perhaps looks through what's in its disk cache, things like that. Those kind of thing is not really a bug, just the program being slow and its UI not being managed by an independent thread.

I'm not sure, but I think this does not happen if you don't use Firefox maximized window.

Can you start firefox with clean profile?

mv .mozilla .mozilla.bk

EDIT: Or if you use firefox profile sync, disable it.
