When I open a link a new window opens with the toolbar and sidebar missing, on my previous machine the link simply opened in a new tab (not window).

When I open a link in Firefox instead of opening a new tab it opens in a new window with all of the toolbars missing including the sidebar, right clicking anywhere gives me no options to restore the toolbars. My old machine simply opened the same link that I am trying in a new tab with all my toolbars available.

You can override how external links are opened via the browser.link.open_newwindow.override.external pref.

The meaning of the values of the browser.link.open_newwindow.override.external are the same as for browser.link.open_newwindow

  • 1: current tab; 2:new window; 3:new tab;

No matter what I do to the browser.link settings the link still opens in a new window and without the toolbar's.

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 or otherwise make changes.

Problem still occurs in safe mode and also with Hardware acceleration off.
