Under options/tabs: open new windows in a new tab instead does not work. many sites open their popups or new windows NOT in a tab as it should. How to solve this, has been a problem in the last versions incl. the latest.

Question

i would like the option ´open new window in new tab instead´ working properly so no new windows will be opened except when I command them to..
as said, many websites have popups (most are blocked, still some come through) who open in a new window.

Answer 1

Type '''about:config''' in the Location (address) bar and press the "Enter" key. When you see a warning, click '''I'll be careful, I promise!''' button.
* Preferences that have been modified are shown as '''bold (user set)'''.
* Preferences can be '''Reset to the default''' or changed via the right-click context menu.
-> In the '''Filter bar''' type '''browser.link.open_newwindow'''
* Right click the preference '''browser.link.open_newwindow''' and click '''Modify'''
* change the value to '''3'''
* click OK
-> In the '''Filter bar''' type '''browser.link.open_newwindow.restriction'''
* Right click the preference '''browser.link.open_newwindow.restriction''' and click '''Modify'''
* change the value to '''0''' (zero)
* click OK
-> Close the '''about:config''' tab and then Restart Firefox.
Check and tell if its working.
