Re: Unable to open a new window.

Do you have that problem when running in the Firefox SafeMode?
http://support.mozilla.com/en-US/kb/Safe+Mode
Don't select anything right now, just use "Continue in SafeMode."

When in Safe Mode...

  • The status of plug-ins is not affected.
  • Custom preferences are not affected.
  • All extensions are disabled.
  • The default theme is used, without a persona.
  • userChrome.css and userContent.css are ignored.
  • The default toolbar layout is used.
  • The JIT Javascript compiler is disabled.
  • Hardware acceleration is disabled.

If not, see this:

Re: Unable to open a new window.

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.

If it works in Safe mode or with all extensions (Tools > Add-ons > Extensions) disabled then try to find which is causing it by enabling one extension at a time until the problem reappears.

Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

The same situation for me.

With ALL extensions disabled (safe mode or disabled by hand) it perfectly works. If you enable a couple of them then it blocks!!!! Whichever two of my extensions are enanbled, the browser ends up NOT being able to open new windows. Only new tabs!

This situation started after updating in version 20 of Firefox. What's more. After meshing around with enabling-disabling, installing-uninstalling extensions it ended up that the majority of them (employing aspects of browser window) doesn't "appear" to work.

Same problem with me.

Open in New Window works correctly in safe mode. In normal mode it doesn't; furthermore if I click on a link that is supposed to open in a new window, nothing happens, and then if I close Firefox and try to open it again it says the process is already running so I have to use Windows Task Manager to end the process (firefox.exe *32).

I have tried disabling all the add-ons, however, Add-ons Manager only shows the plugins (11 of them). Firefox Health Report shows that all 11 plugins are disabled but that 6 add-ons are enabled and one is disabled. I can't find any way to list these add-ons (the Extensions option shows a blank pane), let alone disable them - none of the options in Add-ons Manager lists them (and, by the way, if I select Get Add-ons it just hangs with the circulating dots and the message 'Loading...').

Interestingly, in my search to try to list these add-ons, I got to the Troubleshooting page to find the location of the Firefox Profiles folder and pressed the Show Folder button - which of course did nothing, since it tries to open a new window!! However, using the non-Firefox method of locating the folder did not help, since there was nothing obvious there listing the 6 enabled and 1 disabled add-ons.

I've also tried un-ticking 'Use hardware acceleration when available' in the Options/Advanced/General tab, to no avail.

Appearance in the Add-ons manager shows Default 22.0.

This is driving me crackers. I'm having to use a different browser for some sites where it's imperative to have a link open a new window. Firefox is the only browser I really like (or did until this started happening!).

Re: Unable to open a new window.

Hi PeteThirdEye, did this problem just start recently? Can you associate it with any changes to Firefox, to add-ons, or to Windows?

The Show Folder button should launch a Windows Explorer window (not a Firefox window), so it seems the problem extends even beyond the usual Firefox problem. Have you tried rebooting Windows in case there is some glitch in memory?

Re: Unable to open a new window.

You can check for problems caused by a corrupted localstore.rdf file.


In Firefox Safe mode these changes are effective:

  • all extensions are disabled
  • the default theme is used (no persona)
  • userChrome.css and userContent.css are ignored
  • the default toolbar layout is used (localstore-safe.rdf)
  • the Javascript JIT compiler is disabled
  • hardware acceleration is disabled
  • plugins are not affected
  • preferences are not affected
