Firefox windows opened by javascript fail

I have a script that opens several windows. I've been using it for years. It worked just fine in all the iterations of Firefox 2 and Firefox 3. But in Firefox 4 there are two problems:
1. There is no bookmark bar and nothing I do can make it appear. Firefox windows that I've opened from the menu or the initial window do not have this problem.
2. When I right click a link to open in a new tab the new tab opens on the initial firefox window instead of the window in focus if that window was opened with a script.
It seems that if a window is opened with a script, that Firefox doesn't fully recognize it. Here's the part of my script that opens a new window:
function OpenWindo( URL ) {
intWidth = screen.width - 100; //Adjust for the end of screen (don't know why?)
intHeight = screen.height - 10; //Adjust for the Icon Bar at the bottom of the window.
winprops = "toolbar=yes,location=yes,directories=yes,status=yes"
+ ",width=" + intWidth
+ ",height=" + intHeight
+ ",menubar=yes,scrollbars=yes"
+ ",resizable=yes,copyhistory=yes"
+ ",top=0,left=0"
xyz=window.open( URL, "", winprops)
Thanks for your help

Thanks for posting that solution!

Firefox add-ons take some memory. This amount varies depending on the add-on.
'''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
''(If you're not using it, switch to the Default theme.)''
* On Windows you can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* On Mac you can open Firefox 4.0+ in Safe Mode by holding the '''option''' key while starting Firefox.
* On Linux you can open Firefox 4.0+ in Safe Mode by quitting Firefox and then going to your Terminal and running: firefox -safe-mode (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
* Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.

''Once you get the pop-up, just select "'Start in Safe Mode"''
[[Image:Safe Mode Fx 15 - Win]]
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
Does this decrease the memory usage? Please report back soon.

Why do 2 firefox windows open every time a click on an email i outlook 2010?

No, not thru web access; it is via the Outlook provided thru Microsoft Office.

Right click to open new firefox window opens in wrong workspace

Right click in Mac Dock to open new firefox window opens in wrong workspace.
When a user is in another workspace than the Firefox window, right clicking the Firefox icon in the dock and pressing New Window, should create a new window in the current workspace, Not the work space firefox is already running in.

To be absolutely honest, I can't ever remember a time where this worked in Firefox. I don't think the issue is related to the issue you mentioned, unless this particular issue only occurs if you have a dual-monitor-setup (I do have dual-monitors).
Firefox currently behaves differently to all native Mac apps + most Mac apps that support multiple windows.

When I click on Firefox for the first time after I boot my PC it takes three minutes to but after that new Firefox windows open promptly.

Hello and thank you for being available to receive this enquiry.
I like Mozilla.
I like Firefox.
In recent months I have experienced and accumulation of problems. Today (September 25th, 2011) I have set about trying to deal with them.
After consulting your Troubleshooting Section I have made a range of changes that I hope shall resolve problems like freezing, unresponsive scripts, non responding windows and browser crashes.
At the time of writing I have rebooted after making those changes so I have yet to discover whether they solve those problems.
However, I have chosen o write now as I already am re-experiencing the first problem I encounter when I boot my PC, i.e. Firefox takes three minutes at least to start after I click the icon. Once it has started, however, ne Firefox windows open promptly.
How do I solve this? I rememebr a time when Firefox opened with lightning speed whenever I clicked the icon.
Thank you for your valued help and interest.

Hello Patrick O' D,
In my experience t here are two different problems with the speed of firefox on startup
# your os and setup
# firefox - and exactly what you use with it
Some factors will be down to your OS and for instance what does start up initially, many of those factors will affect other programmes/applications and not only firefox.
Some other factors depend on Firefox and how you set that up, I always like to have the option to using Firebug but realise it cold clash with other software or slow down firefox startup so I only enable it as I need it. see for instance: https://addons.mozilla.org/en-US/firefox/performance/

When I open Firefox another separate Firefox window opens with an ad. How do I stop this?

Since Firefox upgraded to 3.6.12 I have been having a separate Firefox window open everytime I open up Firefox. This separate window has some kind of advertisement. I click on that separate page to close it out and sometimes it also closes out the original I opened up, sometimes it doesn't. It is getting very frustrating to have these other sites just open up and I have to keep closing them out. I have checked my pop-up blocker and it is turned on...but this really is not a pop-up. So how do I get these advertisements to stop showing up?

Sounds like Malware.
Install, update, and run these programs in this order. They are all free for personal use, but some have limited functionality in the "free mode" - but those are features you really don't need to find and remove the problem that you have. '''(Not all programs detect the same Malware.)'''

Additional firefox window opens with "dangerous site"

Twice, in the last week, an additional Firefox window opened in the tray, which, when opened, indicated it was a "dangerous site." I have discovered that, since these events, I have lost at least one log-in (my cookies are not disabled). Microsoft Security Essentials indicates everything is clean. Do you have any idea what may have caused an extra browser window to open & place itself in the tray with a dangerous site inside??

hi dan, this happened with the firefox 33 update, which contains a new technology which will make the browser become more responsive relying on your graphics hardware: http://benoitgirard.wordpress.com/2012/05/15/off-main-thread-compositing-omtc-and-why-it-matters/
however with certain graphic cards & old drivers it unfortunately appears to be buggy and lead to the black screen you've observed.
sorry for the troubles this has caused...

All minized firefox windows open when I open a new window

I have several firefox windows open and minimized. When I try to open a new firefox window, all the minimized windows open and are displayed. I am running firefox 8. How can I correct this so that the minimized window remain minimized when I open a new window?
Running Windows XP.

That issue can be caused by an extension that isn't working properly (possibly Ask.com toolbar).
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.

Ubuntu 10.11 through 10.04. Installed Flash-Aid 2.2.1. If multiple Firefox windows open any attempt to shut a one window, extinguish all windows. But they stay in the background to work invisible.

''After installed ubuntu 10.11 through 10.04, whenever you try to close a window of Firefox, they close all that were open, but only become invisible and continue to work somewhere in the background. If you see a pop-up as the new window and if I want to close it on an simple button "X" then they are all close.
After killing over Terminal and restarts a firefox window, re-engage all windows that have been worked in the background but they are now visible. And again it is impossible to kill only one windows. Help !!!!!!!!

In case anyone reads this, I managed to burn my CD by changing the speed of the burn in iTunes. It was set on Maximum possible and I noticed from the CD Diagnostic report (see previous article) that the speed of the drive was listed as 16, but the burn had failed at 24x, so I reduced it to 12 to be safe, and it worked. It plays okay in the car but I have noticed that when I restart the player, it doesn't seem to recognise the CD and ejects it so that I have to push it back in, and it then starts at track 1 again. Not sure if this is to do with the way it was burned, but at least its playing the tracks!

When opening Apple Mail links 2 Firefox Windows Open, The top one is blank and the one behind it contains the web link page???

Whether with previous version of Firefox, or new one (3.6.4), when I open an Apple Mail link, Firefox opens 2 windows. Top window is blank, window behind it contains web page for mail link that I hit. I can't find anything in preferences of mail or Firefox to resolve this issue.
== This happened ==
Every time Firefox opened

I have discovered one solutionto my problem, which is not really convenient and is something I don't have to do with Safari 5 -- If I have Firefox open, but not a window open, then when I click on an Apple Mail link, only 1 window opens. But I don't always want to have my browser open, so this is kinda annoying. I'd rather not use Safari -- Firefox is so much better. Please fix this! Thanks.

In 4.0.1, if I have multiple firefox windows open, when I try to close one window, it closes all. Why can't I close just one window at a time?

I open multiple Firefox windows so that I can quickly Alt+Tab between windows instead of using my mouse to point to tabs. When I close one of my Firefox windows, the browser closes all my windows. What happen to the "Close" feature under the File tab? Why don't I have the option to close only one window at a time?

I don't understand what happened above, but ericn1, wasn't your problem that you tried to close one browser window using the red X, and ALL of them closed? How did any of the above help you solve your problem? jscher2000 gave you alternate methods of closing windows but said that closing a window with the red X "should" work. It doesn't work, because it is closing ALL your windows, not just the one you are clicking on. I am now having the same problem. with Firefox.
Understand I do not have the problem with any other program. In other words, I can open multiple windows in Paint Shop Pro, IE, Notepad, etc. and close one with the red X and all others remain open. It ONLY happens when using the Firefox browser.
The red X should close only the window that you are in when you click on it.
NOW, before someone suggests tabs, I don't like them and don't use them. My choice. Before someone says my browser is out-of-date, (3.6.13) I am using it because it was the last version that worked reliably on my computers, both at home (Windows 7 Professional) and my office (Windows XP Professional).
When I updated to the last Firefox browser, both computers started seizing up (nothing worked and had to reboot using power button) Removing that version of Firefox and going back to this version solved that problem. Fact remains, version has little to do with this problem. I've seen other posts around the net about this with different (newer) versions of Firefox.
So . . . does anyone have a solution to this that doesn't involve using keystrokes or hot keys to close windows instead of the red X that should work properly?

When downloading course materials from Moodle, why do new Firefox windows open repeatedly and indefinitely until I FORCE QUIT?

I use Moodle for my University courses. Moodle recommends using Firefox. Lately, when I download materials for my courses, Firefox begins to rapidly open new blank windows and will not stop until I Force Quit. I also am left with as many blank documents in my Downloads Folder as the amount of opened windows. Occasionally, when my required materials are successfully downloaded, the document will cause the aforementioned problem to begin again. I have removed Firefox and then reloaded and it is still occurring. I have attempted to use Safari and have not had the same problem. I would prefer to use Firefox but am reaching the limit of my patience and am about to say goodbye forever.

See [[Firefox keeps opening many tabs or windows]].

Does window.opener persist (javascript)?

If a new popup (created from a parent window) uses window.opener, and the popup reloads itself when it's form is submitted to the same page by calling the same url (jsp) it was created with, does the window.opener retain it's handle on the parent window? Assume both the parent and the popup are never closed between submissions.
In simple testing, I am finding that window.opener is in fact retained, and the popup can manipulate the parent window even after the popup is reloaded. Likewise, the parent window can still be manipulated from the popup when the parent is reloaded. But I just wanted to more sure before I incorporate this in a larger application, in case my simple test was some accidental fluke.
I realize javascript variables are normally reloaded, but my initial testing suggests that the window.opener is a special persistant variable.

Curt,
In the DOM opener is a Window property, therefore, if neither window is closed, all of the window properties persist.

FireFox windows open in the taskbar change position

Have 3 or 4 windows open. When working on a window it hangs for a few second, then moves to a different position on the taskbar. Happens on my laptop with Vista and new desktop with Windows 7. The window that hangs will move to the last position after hanging. How do I keep the windows open from moving on the taskbar?
== This happened ==
Every time Firefox opened
== I upgraded to version 3.6

Hello Nordhaus.
If you rightclick any task in the taskbar you can select to "pin it to the taskbar". That's handy with Firefox because you'll be able to open it from there, instead of going to the start menu.

I want multiple Firefox windows open w/different View settings - toolbars displayed in one, not in other. With the new version, I can no longer do that ?

I want to remove the toolbars in one open instance of Firefox but not in others.......this was possible in the prior version. Now if I change the settings in one instance, it automatically changes in the other open Firefox windows. How I can I make this work as it did before the upgrade? Thanks, Kris

Thanks a million! It was not intuitive to "swipe" the open applications up but it works perfectly!!
Thank you
