Firefox will only open once per login

This started acting up i think around when i updated firefox when i was opening it. It only allows me to have one firefox window open. The tabs work find but i can't move tags to new windows, can't get on chat sites cause they require another window to open and i have to restart my computer if i close firefox window. I've cleared the cookies on here but doesn't seem to help.

Re: Firefox will only open once per login

Have you cleared the cache as well? If that does not help, some troubleshooting may be in order.

Re: Firefox will only open once per login

Maybe you could explain the situation in more detail.

Are you able to open more windows once Firefox is running ?
for instance

  • right clicking (Windows) a tab and using the option move to new window
  • dragging a tab up and on to the desktop

Exactly how did you open multiple windows previously ?

Or are you thinking of popup windows that a single site spawns, or for instance mediaplayers.

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.

Re: Firefox will only open once per login

John, I'm not able to open more windows after i start up firefox. It will only allow me to have one window open and it won't allow me to move tabs to new windows. I didn't really use other windows cause that's a bit messy. I'm thinking pop up windows that some chat sites use (exp: teenchat). I also realize that, when i was trying the troubleshoot steps, I can't go to add-ons either under the firefox tools.

I tried restarting firefox but that doesn't help. I've tried everything on the trouble shoot page that finitarry sent. Doesn't work

Try to open a new window by adding a space and -new-window about:blank to a copy of the Firefox desktop shortcut.

I really don't understand how to do that and don't have a lot of time to try and figure that out atm...

You can make a copy of the Firefox desktop shortcut and open the Properties of that shortcut via the right-click context menu.

You can add a space and the "-new-window about:blank" text without quotes to the current command (target) line to open the about:blank in a new window if you use that desktop shortcut to launch Firefox.


Try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.

Create a new profile as a test to check if your current profile is causing the problems.

See "Creating a profile":

If the new profile works then you can transfer some files from an existing profile to the new profile, but be careful not to copy corrupted files.

Okay, so i think it's my current profile that is causing the problem. I made a spare profile on my computer and firefox works find on there.
