Browser.link.open newwindow.restriction
Background
Using JavaScript, web page authors can open new windows using window.open()
. However, many users prefer using tabs to multiple browser windows. If the user has set new windows to open in tabs, this preference allows for fine-tuning of just which JavaScript-opened links will be opened in tabs.
Oftentimes when a new window is opened from JavaScript, it’s a small popup without all of a usual browser window’s features—e.g., the back/forward/reload buttons are hidden, the status bar is hidden, the size is purposely smaller, etc. Usually in this situation, the window is designed specifically as a popup, and opening it in a tab actually makes it less useful. This preference can let these types of links open as new windows while opening all other types as new tabs.
Possible values and their effects
0
Divert all window.open
calls according to how browser.link.open_newwindow is set (i.e., into new tabs if it's 3, new windows if it's 2, or the current tab/window if it's 1). (Default in Firefox 1.0.x and SeaMonkey)
1
Do not divert any window.open
calls (allow JavaScript to open new windows).
2
Divert all window.open
calls according to browser.link.open_newwindow unless the new window specifies how it should be displayed. (Default in Firefox 1.5 and later and Camino 1.5)
Caveats
- browser.link.open_newwindow determines where diverted
window.open
calls go. If it's set to 2, this preference will have no visible effect. - Until recently, the default of this preference in Firefox was 0.
