Firefox won't open new windows as maximized

I'm running Firefox 31 on Windows 7, and in the program properties I've set it to run "maximized". When I open a new browser window using either the desktop or start menu shortcuts or "File > New Window" in the browser itself, it opens maximized just as it should. However, when I click a link that's programmed to open in a new window, the new window consistently opens as "normal window" rather than "maximized". I find this incredibly irritating.
This problem did not occur at all back when I was using Firefox 28.
I have not been able to find any way to correct it in the settings or options, nor have I been able to find any remedies in the form of add-ons. Does anyone know how to fix this?

Well that looks easy enough.
Will toolbar customizations be the ''only'' thing I'll lose if I delete my localstore?

Firefox won't open new windows or upload video

Firefox is starting to get on my nerves with this one. The program will be working fine and then suddenly stop opening new windows. For example, I'll take a quiz and want to upload my results to facebook. I'll click the button and instead of opening a new window for facebook, it does nothing. Another example: I'm taking an online course and if I click to upload a file, instead of opening a window, it does nothing. When I click the red X to close firefox, nothing happens. Also, the minimize, restore, and close window buttons no longer respond. I have to open my task manager and manually stop the process. I notice when I reopen the program, it offers to restore all of my tabs as well as windows that mysteriously never opened before. This has been going on for about a week now and it really is annoying. I also notice when this happens that firefox seems to be taking up an unusual amount of RAM on my computer. What gives?
I am using the most recent version of Firefox on a Dell PC and running the most recent version of Windows 7.

Hi JuMaGa86,
Thank you for your question. This sounds like a performance issue, please try these troubleshooting steps [[Firefox uses too much memory (RAM) - How to fix]]
Then clear your cache and run the browser for a while to see if the performance improves. We look forward to your reply!

Firefox won't open new windows when I click "File" and "New Window". can you help me?

My question is just as it reads above. My computer is windows 7. I've never run into this before.

This issue can be caused by an extension that isn't working properly.
Start Firefox in [[Safe Mode]] to check if one of the extensions 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.

Firefox 4 stops opening new windows after browser window dragged to second display

Firefox 4 stops opening new windows after browser window dragged to second display. It's weird. Behavior is fine until I drag any browser window to the attached second display, and after this point it stops opening new windows but will still open new tabs in the same window. Restart fixes it until I drag the window back to the second display.
"Show all bookmarks" stops working too--won't open a new window.
This is after clean reinstall with total deletion of any Firefox/Mozilla folders and the previously installed app and a restart of the computer.
Mac OS X 10.6.7
Firefox 4

Pretty sure this is either:
'''Bug 644733'''
or
'''Bug 609405'''
(...and they may be reporting the same thing.)

The firefox will not open new windows

My firefox will not open new windows. It opens new tabs. The problem is in the windows.

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 or otherwise make changes.
*https://support.mozilla.org/kb/Safe+Mode
If it does work in Firefox Safe-mode then disable all extensions (Tools > Add-ons > Extensions) and 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")
*https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
Create a new profile as a test to check if your current profile is causing the problems.
See "Creating a profile":
*https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
*http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If the new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

Firefox 31 (Ubuntu) won't open new window or Javascript pop-ups

Hi, I am running Firefox 31.0 in Ubuntu 14.04 having the following problem:
1) When I click on New Window or New Private Window in the File menu, nothing happens, same with pressing Ctrl-N.
2) Certain websites are not able to open new windows or pop-up windows through Java or Javascript
(e.g. the command: javascript:popup_imp(...) does not produce anything)
I did try safe-mode and there everything works fine. Then I restarted firefox (several times) with all plugins disabled but still had the same problem, so I don't know what causes the difference between safe-mode and no plugins.
(By the way, there is no problem opening a New Tab by pressing Ctrl-T or from the file menu, the issue is only the New Window and New Private Window).
Is there any other way to narrow down what is preventing the new windows?

Hi cor-el,
thanks for your answer, however as I explained in my post, safe-mode does not present the problem, but disabling the extensions on its own does not help (i.e with all extensions disabled the problem still is there).
Also, I did not have this problem in the past and I did not change anything graphics related (unless something was changed software-wise internally and I did not notice).
And yes I am currently using the default theme.

Firefox will not open new window, Why?

I have Vista home base premium operating system. I am a regular user of Mozilla firefox after had lots of positive feedback as one of the best browser. I had no problem for a good while, until recently I found out my add-on firebug stop working. Then I noticed that firefox stopped working properly, ie; it will no more open new window/s. One window will open after rebooting and i can have a number of tabs opened. When I right click on a web link and take the option to open it in a new window it will not open. When I take the option to open it in a new tab then that would be ok. When I go to the toolbar and click on File and chose option "open new window" again it will not open. I have on many accasions completely installed Firefox using the IObit software and use the advance system care to clean the registry and completely scan the system. I then reinstalled the latest version of Mozilla Firefox. I did that twice. The problem is still there. About the ad-on firebug, when I go to the toolbar and click on Tools, i can see Firebug with the extended arrow, but when I click on the arrow to the extended options, it simply would not respond.
There must something going on, please help.

Embedded links in emails won't open new window or tab in FF.

Running Mac OS X 10.6.6 and FF Version 3.6.12. I'm using Mail Version 4.4 as my email client and when I try and open an embedded link from an email, the link doesn't open a new tab or window. FF recognizes the link, but doesn't respond with a new tab or window. If I copy and paste the link into the browser the links work fine, so I feel like it's a setting or bug that has been changed somewhere somehow. This problem only happens when I try to click directly from the email. I've tried searching the preferences in both Mail and FF, but can't seem to find anything that fixes the problem. This issue started happening two weeks ago when I did the latest Mac OS X security update. Any thoughts or suggestions?

Hi everyone, I have Snow Leopard 10.6.8. I have been very very frustrated by this problem. [I could not create new windows, and anything that opens new windows, such as trying to see what Add-ons you have etc would not work]. I read about changing screen alignment to the top... I have one screen so the option does not exist. The above messages would not fix this problem. I searched hard and did find a solution in the end. I read stuff about removing Add-ons until the problem is fixed, but its simply not the case.
First of all open Firefox. next go to options: Help --- 'Restart with Add-ons disabled'. Tick the box for add-ons, restart firefox. Next go to Tools --- Add-ons. Next (In the Add-ons Manager' click on 'Plugins' on the left hand side pane. Look for the small blue writing that says 'Check to see if your plugins are up to date'.
Now notice it should say 'Missing Flash'. "For your safety, Firefox has disabled your outdated version of Flash. Please upgrade to the latest version". I followed this, reinstalled Flash and it now works as it always did, no problems. For people where the above fix didn't work, try this one out. Hope it helps people!

Won't open new window, only tabs

Previous version I could change option to open new window rather than tabs in 'tools' - 'options' This does not change anything. Also, it no longer saves 'home page'

I used Computer Associates ver.7.0.0.117 to clear temp files and cache. Firefox won't open a window since though it shows in processes.

System: Toshiba Portege M750, Vista 32-bit SP2,4GB RAM
I've been using Firefox up until last night when I shut down. This morning I did a cache cleaning using CA Internet Security Suite, ver 7.0.0.117. Firefox will not open a window, though it does show in the Processes list of Task Manager.
I've uninstalled and reinstalled ver 6 from the web twice with the same results.
Firefox has had a tendency to hang (never finding a new website, i.e. busy icon revolves endlessly) when left open over several hybernation cycles.

'''Kill Application'''
In Task Manager, does '''firefox.exe''' show in the '''Processes''' tab?
See: '''[http://kb.mozillazine.org/Kill_application Kill Application]'''
'''Causes and solutions for Firefox hanging at exit:'''
'''[[Firefox hangs]]'''
'''[http://kb.mozillazine.org/Firefox_hangs#Hang_at_exit Firefox hangs at exit (Mozillazine article)]'''
'''[[Firefox is already running but is not responding]]'''
'''Safe Mode'''
You may need to use '''[[Safe Mode]]''' (click on "Safe Mode" and read) to localize the problem. Firefox SafeMode is a diagnostic mode that disables extensions and some other features of Firefox. If you are using a theme, switch to the DEFAULT theme: Tools > Add-ons > Themes before starting Safe Mode. When entering Safe Mode, do not check any items on the entry window, just click "Continue in Safe Mode". Test to see if the problem you are experiencing is corrected.
See:
'''[[Troubleshooting extensions and themes]]'''
'''[[Troubleshooting plugins]]'''
'''[[Basic Troubleshooting]]'''
If the problem does not occur in Safe-mode then disable all of your extensions and then try to find which is causing it by enabling one at a time until the problem reappears. You have to close and restart Firefox after each change via File > Restart Firefox (on Mac: Firefox > Quit). You can use "Disable all add-ons" on the Safe mode start window.

I have not checked "Open new windows in a new tab instead" but Firefox 5 keeps opening new windows in a new tab. How do I stop this?

I do not want to use the tab feature.
I have an iMac OS 10.6.8

(''Note: cross posted from [https://support.mozilla.com/nl/questions/801471 here].'')
I had the same problem, but was able to fix it somewhat.
# Open the about:config page.
# Set the ''browser.link.open_newwindow.restriction'' setting to 0 (= zero).
On my machine this will open new windows in a new tab. However, it switches to the new tab regardless of the setting ''"When I open a link in new tab, switch to it immediatly"''.

Firefox won't open new tab, have to open new window for any link.

New tab won't open both when attempting to do it by clicking on "cross" in the tabbar or from File >> new tab.
Thanks
