While I'm googling and looking at documentation and config menus to find an answer, I figured I might post it here to see if I can get a quick response.
To be blunt, I hate the new alert windows that Firefox 4 produces and would like to be able to revert back to the way it has been done in previous builds and other browsers; Namely, a simple Windows message box. Specifically because I've found that the new message box is modal to the wrong window or tab which tends to lead to situations that you don't even realize you're getting an alert until you've performed the operation several times, nothing has happened, and -- confused -- you've switched back to the main window only to find a queue of identical alerts as to what went wrong. Now, don't get me wrong, I'm sure if you trace it back to how it's working you'd find that this is caused by poor site development more than poor browser development, but at the same time, the site was developed when it was more or less standard for a message box to pop up over all windows rather than within the window it is called from. I suppose it is subjective and entirely dependent on scenario as to which is better.
Regardless, has anyone found a way to change this or can anyone conclusively say that it can't be done through settings?
