Firefox crashes, typically (but not exclusively) when opening a new window.

Firefox has been crashing every couple of hours for the past month or so. It seems to happen the most when I open a new tab, but I think it has crashed other times too. I have also seen it get up to 1,000,000+K in my memory (running at 432,000K right now).
Hardware acceleration has been off and that hasn't helped.

Wyoung221: I've looked over your crash reports and two things are consistent.
1) Your crash report signatures are consistent with one signature (gfxContext::PushClipsToDT(mozilla::gfx::DrawTarget) which refers to graphics. (1)
There's one signature (mozilla::WebGLTexture::DoDeferredImageInitialization(unsigned int, int) that has a new bug filed on it but it's stalled.
2) Your System Memory Use Percentage hovers around 70-80% so this could be out of memory crashes as well. (2)
1. Firefox has hardware acceleration set to "on" by default, but it's still young, which means some video cards or drivers might have problems with it. You can try to disable hardware acceleration in Firefox (you need to close and restart Firefox).
*Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
2. In addition to the hardware acceleration, the System Memory Use Percentage in the crash reports is rather high, so this might be out-of-memory crashes

Firefox is already running, but not responding to open a new window

I closed the only opened Firefox process that was running. Then clicked the Fox to start Firefox again. I received a message: Firefox is already running, but not responding, to open a new window. You must close the existing Firefox process, or restart your system. This is a stupid message since there is no Firefox in process.
== This happened ==
Not sure how often

Hello Lara.
Hopefully this support article is what you need:

Firefox is not opening and saying " firefox is alredy running but not responding ,to open a new window you must close the existing fireox process" even though there is no other window open

this has been happening since i updated i have windows 7 but firefox beta used to work just 3 days ago i had mcafee site advisor but i deleted it its not working every time i click on the icon it displays the above message

I discovered that when the "Firefox is already running . . . ." message pops up I can fix it by doing the following [note: I get the same message for the Thunderbird e-mail program too] : 1. I open 'TASK MANAGER" and click on the "Processes" tab. 2. Next I scroll down until I see Firefox.exe *32 in the leftmost column (or Thunderbird. exe *32 if the message came up there), highlight that line by clicking on it and then click on the "end process" button on the right side on the bottom. 4. A pop-up window will come up but ignore its message and click on the "end process" button in the pop-up window. The program should then start the next time you click on the icon..
While that saves the need to restart your PC to fix the problem, I have yet to find any information as to the reasons for those two processes to show up in the first place. I'm running the 64 bit Win 7 Professional and do not know if that has something to do with those two processes running from time to time or not. The message comes up often but not all the time and I haven't been able to pinpoint any action on my part where the message comes up if I do '''X '''or the message never comes up when I do '''Y''' before closing Firefox or Thunderbird.

I open firefox it keeps saying"Firefox is already running,but not responding.To open a new window,you must first close the existing Firefox process,or restart your system" i tried restart my computer...but it's still keep saying that..pls help me..

As I stated above, I have to constantly restart my computer because I get a message stating firefox is already running.

Do you see a firefox.exe in the Task manager if you look there right after you get this error message?
You do not have to restart the computer, just kill that process.
This situation may occur if Firefox was not closed correctly or crashed.

Recently viewed sited not showing when opening a new window; tried to rest browser.newtab.url and browser.newtabpage.enabled ; rest is greyed out

how to display top or suggested sites as tiles? I cannot perform this task. Please assist.

I don't get it. Maybe you have a hidden extension? Those are disabled in Firefox's Safe Mode. That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: [[Troubleshoot Firefox issues using Safe Mode]].
You can restart Firefox in Safe Mode using either:
* "3-bar" menu button > "?" button > Restart with Add-ons Disabled
* Help menu > Restart with Add-ons Disabled
Not all add-ons are disabled: Flash and other plugins still run
After Firefox shuts down, a small dialog should appear. Click "Start in Safe Mode" (''not'' Reset).
Any difference?
In case your Firefox program files got damaged by the latest update, you could try the following type of reinstall that does not touch your settings files. Important: do NOT uninstall Firefox first. That is not needed.
'''Clean Reinstall'''
(1) Download a fresh installer for Firefox 36.0.1 from https://www.mozilla.org/firefox/all/ to a convenient location. (Scroll down to your preferred language.)
(2) Exit out of Firefox.
(3) Rename the program folder
''(64-bit Windows folder names)''
C:\Program Files (x86)\Mozilla Firefox
to
C:\Program Files (x86)\OldFirefox
''(32-bit Windows folder names)''
C:\Program Files\Mozilla Firefox
to
C:\Program Files\OldFirefox
(4) Run the installer you downloaded in #1. It should automatically connect to your existing settings.
Any improvement?
Note: Some plugins may exist only in that OldFirefox folder. If something essential is missing, look in these folders:
* \OldFirefox\Plugins
* \OldFirefox\browser\plugins

I try to launch firefox get the following message "firefox is already running, but is not resonding. to open a new window, you must first close the existing firefox process, or restart your system" firefox is not running and restart doesn't work

when I launch firefox get the following message "firefox is already running, but is not resonding. to open a new window, you must first close the existing firefox process, or restart your system" firefox not running and a restart doesn't solve the problem

Download a fresh Firefox copy and save the file to the desktop.
*Firefox 12.0.x: http://www.mozilla.org/en-US/firefox/all.html
Uninstall your current Firefox version, if possible.
*Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you will also lose your personal data like bookmarks and passwords from profiles of other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
*It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
*http://kb.mozillazine.org/Uninstalling_Firefox
Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

I sometimes have blue and red square-shaped dots appear on my MBP; especially but not exclusively when I'm watching videos. The dots don't stay in the same place; and also they are not there all the time.

I sometimes have blue and red square-shaped dots appear on my MBP; especially but not exclusively when I'm watching videos. The dots don't stay in the same place; and also they are not there all the time. Also, sometimes my animations (applications opening, windows being dragged, etc.) will glitch as well. Again, this is not a continual thing; it just happens variously throughout my day. MBP Model A1212, OS X 10.6.8, 2.33 Ghz 3GB RAM.

Did the original songs that do not appear on the car player play in the Music app on the iPod? Sometimes glitches happen and they do not. Also, If y ohave a 5G iPod/iOS 7, purchase songs will show with an cloud icon by them if they are not downloaded if Shall All is turned on in Settings>iTunes and App Store

Get message firefox already running but not responding when trying to launch..tells me to close firefox wondow and try again (no ffox window is open)

When trying to launch Firefox I get the following message.
"Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system."
This is not the first time and I am tired of having to restart my computer. BTW I have Firefox as my default browser, but had to use IE to get to this support site!
In answer to the next question...every time I TRY to open Firefox.

Simple fix for you I think--it works for me.
1. Open your TASK MANAGER (rt click on your taskbar)
2. Go to PROCESSES
3. Scroll down until you see "firefox.exe"(or anything with the word Firefox in it)
4. Click(highlight) the "firefox.exe"
5. At the bottom right side,click "End Process"
6. Close the Task Manager and do whatever you were attempting to do.

TypeError:undefined is not an object message when opening a new window in Bridge

Every time I open a new window in Adobe Bridge CS6, I get a long error message that says
"TypeError: undefined is not an object: onResize()buildUIStack(true,"Cabinet")buildUIStack([TabbedPalette:[objectTabbedPalette]], true,"Cabinet")switchTo([TabbedPalette:[objectTabbedPalette]],[Group:[object Group]],true)AmgDesignWindow([TabbedPalette:[objectTabbedPalette]],[Group:[object Group]],true)populate([Group:[object Group]],true)"
I'm running OS 10.8.5. I've tried uninstalling and then re-installing CS6 but I still get this error message. Once I click OK, a new window will open. I just want to know how to stop this message from popping up every time I click "new window".
Any help is greatly appreciated.
Thanks!

It could also be a bug in OS. Did it work before? If so reset preferences. Hold down Option key and start bridge. You should get a reset window.

When opening a new window, it automatically loads last pop-up (?) content and I am unable to type in address bar or open a new tab in the new window.

I don't know if they're technically pop-up windows (for example, if you do a search on kayak.com, it will automatically open a new priceline.com window with the results of the search), but this happens with pop-up blocker on or off. Other examples are a small info window from a financial or .edu site that opens up saying a session is about to expire, or answering an FAQ (with the exception of the priceline example, these windows don't have an address bar or display a URL). Anyway, after these windows are closed, if I try to open a new window, it will automatically load the content of that "pop-up". Whenever it does this, I am unable to type in the address bar or open a new tab in that window.
How do I fix this? All I want is to open a new window that's blank, not load prior content.

It could be the work of one of your add-ons, or even add / mal-ware.
Look thru your add-ons list and make sure you know what each one is
there for. Also, check the programs that are on your computer
'''Windows > Start > Control Panel > Uninstall Programs.'''
'''(Mac: Open the "Applications" folder)'''
Go thru the list and use a web search to check any that you don't
know what they are.

Firefox took more than 15 minutes to open a new window

Hi all,
I'm now with the last version of firefox 3.6 and it took more than 15 minutes to open a new window. But, i'm not having the problem to open a new tab. I don't know why?
I'm on window XP, antivirus: avast familly.
Thanks for your answer.

Error message when opening a new window.

Whenever I open a new window beside the initial one (by link or otherwise), I get this message:
Exception in LoadPrefs: TypeError: gBrowser.browsers[i] is undefined
The page appear, but it seems to have the default display (without my preferences or my bookmarks) and the content often isn't loaded.
P.S. I can't send my Troubleshooting Information because it's
31 355 characters long (instead of 30 000). Is there a way to send it?
Thanks in advance

Try doing the following:
ctrl+alt+del >> Go to processes >> If their is more than one firefox.exe running, end one of them.

When opening a new window, it just stays blank. For instance when I try to play a card game in yahoo games.

When I go to open a new window by the result of trying to open something on a page, the new window stays blank. There is no error message or anything, it just stays blank.

It could be the work of one of your add-ons, or even add / mal-ware.

When opening a new window stopping the I bar from automatically showing up in the address bar instead of the search bar

I want the I bar to start in the search bar when opening a new page NOT the address bar.
Thank You.

What's an "I bar?"
