Firefox 4 opens 2 windows at startup

Desktop with Windows XP and Firefox 4. When openning Firefox from a URL, 2 windows open (one with the Home page and one with the URL webpage). If Firefox openned from the Application only one window opens with the Home Page. How do I stop the 2 windows when selecting a URL?

Unless the schedule it's running on is every single time I open Firefox (including closing it & reopening it right away), I don't think that's the case. Also, I don't have any of these issues on the PC I switched back to v3.6 on. That one runs smoothly whether I run Ccleaner, registry optimizers, clear the cache & history or whatever. I thought after you first gave me the answer of deleting the session files that they must've got corrupted during the upgrade, but it seems that v4 just doesn't do a good job of retaining or maintaining those files without getting them corrupt or something.
If this is not an issue with everyone & I'm having it on both my PCs, then v4 has an issue with something that I install on my PCs that, I guess, many others don't although I don't know what that could be and I use everything I install or have running. So, I'm just going back to what works without having to dismantle my config one prog at a time to try to find what v4 may be finicky about.
By the way, I did check & couldn't find any cleaners that run automatically on my PCs.

How do I set Firefox to open new windows in a separate window (not in tabs)?

How do I set Firefox to open new windows in a separate window (not in tabs)?

Click the orange Firefox button, and click "Options". This will bring up a new window with a "Tabs" tab at the top. Click that. There will be several checked boxes, including one called "Open new windows in a new tab instead" up at the top of the list. Uncheck that box and you should be good to go.
ETA: This should also work if you click "Tools" and "Options" within your version.

Whenever I start Firefox it opens 10 windows with blank tabs

Every time I start up firefox it opens 1 window with the open tab from my previous session and 9 more windows with blank tabs.

It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
Delete the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
* Help > Troubleshooting Information > Profile Directory: Open Containing Folder
* http://kb.mozillazine.org/Profile_folder_-_Firefox
* http://kb.mozillazine.org/sessionstore.js
If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well. 
Deleting sessionstore.js will cause App Tabs and Tab Groups and all open tabs to get lost, so you will have to create them again (make a note or bookmark them).

Firefox keeps opening multiple windows when web link to iTunes clicked.

Running Windows 7, 64 bit. Clicked the "View in iTunes" button on this page, https://itunes.apple.com/gb/app/smartscan-express-fastest/id533516060?mt=8
Link did not open and instead Firefox kept opening another window continuously until there were dozens of windows opening one on top of the other. The only way to stop this was to Shut Down the PC. This has happened on several occasions and it's always when a link to iTunes is concerned.

Sorry, this can happen when Firefox asks how you want to open something that Firefox doesn't know how to open, but you tell Firefox to go ahead and open it. This article describes the various ways to resolve it: [[Firefox repeatedly opens empty tabs or windows after you click on a link]].

Why does Firefox not open my windows and tabs from last time until I have tried starting 3 or 4 times?

I have this problem with opening Firefox:
My Startup options are set to "When Firefox starts: Show my windows and tabs from last time"
However, each time I start Firefox, by clicking the icon in the Taskbar, it opens with a single blank tab.
I repeat this using "Open New Window" and when I have up to 3 windows, all with single blank tabs open, I close them all. Once more I use "Open New Window" which only then opens with my windows and tabs from last time.
Naturally, this induces initial panic each time, because I dread the thought of losing all my current tabs.
What is going on here?
How can I fix it?
< Firefox 27.0.1 with Windows 7 Home Premium.>

This started happening to me with the upgrade to v30. Previously, new windows did the proper thing of showing previous tabs/windows.
I have history on, not in private mode, and have cleared cache.

When I first pick firefox to open two windows come up. one is welcome to firefox and it has a pop up box asking someting about shopping. the second window is the start page

When I first open firefox, two windows open at the same time. Welcome to firefox with a pop up window and the second one is the mozilla firefox start up page. It is very annoying.

Hi mjp80538,
You should look at [https://support.mozilla.com/kb/Firefox+has+just+updated+tab+shows+each+time+you+start+Firefox this article about that specific issue] and the article [http://kb.mozillazine.org/Preferences_not_saved Preferences not saved]. These should give you all the information you need!
If that doesn't work:
# Type about:config in the address bar
# Click ''I'll be careful, I promise'' if prompted
# In the Filter input field type ''startup''
# Double click on startup.homepage_override_url
# Delete the text string and click ''OK''
# Close Firefox and reopen the window to verify that it has worked.
Hopefully this helps!

Why does Firefox keep opening new Windows rather than a new Tab in the current window?

I have " Open a new Tab in the current Window" select in Preferences.
Why then does this version (Version 4) keep opening new Windows, rather than new Tabs in the current Window.
This feature worked fine in 3.6.1.3, but in Version 4, it is a frigging pain in the rigging!
C'mon, Mozilla - time for an URGENT update ...

That issue can be caused by an extension that isn't working properly.
*https://support.mozilla.com/kb/Troubleshooting+extensions+and+themes
Start Firefox in [[Safe Mode]] to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

How do I set Firefox to open new windows in my second monitor?

When opening a new window (by right clicking a link and selecting Open in New Window), I would like the window to be opened in my second monitor. Firefox used to do this, but randomly stopped. Now when I open a new window it is opened in my primary monitor. It does not open maximized (just short of being completely maximized). I have tried the fix I used before- moving the un-maximized browser to the second window, closing and re-opening the window. I have also tried moving the un-maximized browser, maximizing, closing and re-opening. Does anyone know how I can restore Firefox to open my new window in the second monitor?
== This happened ==
Every time Firefox opened
== Randomly

Click the orange Firefox button, and click "Options". This will bring up a new window with a "Tabs" tab at the top. Click that. There will be several checked boxes, including one called "Open new windows in a new tab instead" up at the top of the list. Uncheck that box and you should be good to go.
ETA: This should also work if you click "Tools" and "Options" within your version.

I cannot re-open Firefox, or open another window, without rebooting

I get a message indicating that Firefox is already operating and to either close the program or reboot. I cannot access the supposedly open program, nor can I open another window. I am using Windows 7. The problem repeats itself even after rebooting.

Firefox is opening multiple windows without my request. The only way I can stop it is by rebooting my computer.

Fairly often when I open Firefox, it continues to open multiple windows (hundreds of them) without my request. The only way I can stop it is to reboot the computer.
== This happened ==
A few times a week
== Several weeks ago

Hello Sally.
This looks like some virus or spyware. Scan your system for infection.
Or you may be having a problem with some extension or plugin that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?

Firefox repeatedly opens multiple windows

Just over a week ago, I started having problems where Firefox would repeatedly open new windows as I was web surfing. Each new window is the same. They each have 3 (three) open tabs. The first tab has the url: http://search2.comcast.com/?cat=dnsr&con=ds&url=www.d.com. The second tab has the url: http://xn--xp~n ' ss14-boa27f6hze459aca6942lr1a/. And the thrid tab has the url: http://www.xn--}j--znas1698b.com:5/. The URLs for the tabs never change. In many cases, Firefox will open 5 or 6 windows all of them as described above.
I have uninstalled and reinstalled Firefox twice. I have run anti-virus/anti-spyware (Malwarebyte's Antimalware and Trend Micro 2010) with no malware found save for several cookies. I am at a loss and the problem is extremely annoying. Can someone please help me get this fixed?

Do a malware check with some malware scanning programs. 
You need to scan with all programs because each program detects different malware. 
Make sure that you update each program to get the latest version of their databases before doing a scan.

Firefox is opening new windows automaticly most often when I move the curser

Firefox has started opening new windows that show redirect. This happens most often when I move the curser. The problem is intermittent as it seems to stop when you close all the windows at times. Then when you go to a new page it starts opening new windows again.

If this affects a lot of sites randomly, there's a good chance it is caused by an add-on. Try this:
Disable ALL nonessential or unrecognized extensions on the Add-ons page. Either:
* Ctrl+Shift+a
* "3-bar" menu button (or Tools menu) > Add-ons
In the left column, click Extensions. Then, if in doubt, disable (or if obviously bad, remove).
Usually a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step.
Does that shut down the extra windows?
Also recommended:
(1) Visit the Windows Control Panel, Uninstall a Program. Click the "Installed on" column heading to group by date. Then look for any recent unrecognized programs that may have snuck in as part of a bundle. Remove everything you do not know to be useful and trustworthy.
(2) Our support article lists some other scanner/cleaner tools that you may find helpful: [[Troubleshoot Firefox issues caused by malware]].

Firefox cannot open new windows

I have done everything possible to fix this issue. When I install firefox, there is no issue with opening extra windows (not tabs). However once the computer is restarted, and firefox brought up, it will not open links in new windows but will open it in tabs.

You can check some prefs on the about:config page to be sure that these are correct.
*http://kb.mozillazine.org/browser.link.open_newwindow
*1: current tab; 2:new window; 3:new tab;
For links opened via JavaScript you can look at this pref:
*http://kb.mozillazine.org/browser.link.open_newwindow.restriction
Start Firefox in [[Safe Mode|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
*https://support.mozilla.org/kb/Safe+Mode
*https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test.
