My tabs still open in new window even after deselecting that option, how do I fix that?

Posted

Each time I try to load a new tab in the same window, Firefox opens a new window. I have gone through the process of deselecting "open tabs in new window" but it is not working. I have also uninstalled and re-installed, but no difference.

Chosen solution

There are two common reasons for this problem:

(1) Site uses a script that launches the window, and it has parameters such as height and width, or restrictions such as no scroll bars. In these cases, Firefox assumes it is a dialog related to the page and always uses a new window. (There is an override for this I will mention later.)

(2) If the page you are viewing is in a dialog window, Firefox may not be willing to open ANY new tabs in that window. Usually in this case the tab bar is missing or the "+" button doesn't work. But if you open a new window using Ctrl+n then links should work normally.


To force even scripted popups into a tab, you can change a setting under the covers.

(1) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.

(2) In the search box above the list, type or paste link.o and pause while the list is filtered

(3) In this case, check out setting (B) to zero. The others are here for future reference:

(A) browser.link.open_newwindow

3 = divert new window to a new tab (default) (checked*) 2 = allow link to open a new window (unchecked*) 1 = force new window into same tab

* First checkbox in Options > Tabs

(B) browser.link.open_newwindow.restriction - for links in Firefox tabs

0 = apply the setting under (A) to ALL new windows (even script windows) 2 = apply the setting under (A) to normal windows, but NOT to script windows with features (default) 1 = override the setting under (A) and always use new windows

(C) browser.link.open_newwindow.override.external - for links in other programs

-1 = apply the setting under (A) to external links (default) 3 = open external links in a new tab in the last active window 2 = open external links in a new window 1 = open external links in the last active tab replacing the current page

can you enter about:config into the firefox address bar (confirm the info message in case it shows up) & search for the preference named browser.link.open_newwindow - right-click and reset that entry to the default value...

On the Tabs panel of the Options dialog, there is a setting for how Firefox should handle links that are coded to open in a new window: divert them to a tab or let them open in a new window. You can check that setting here:

"3-bar" menu button (or Tools menu) > Options > Tabs

Check the box for "Open new windows in a new tab instead"

Is that what you meant?

If not, could you describe the type of link or bookmarks that is causing the problem, for example:

  • Click a link on this page
  • Click a link in search engine results
  • Use a bookmark
  • Click a link in an application outside Firefox

Regardless if I check or "uncheck" -Open new windows in a new tab instead- I still get new windows. I would like to get tabs instead.

See:

For links opened via JavaScript you can look at this pref:

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
  • Do NOT click the Reset button on the Safe Mode start window
