Whenever I open new tabs Firefox crashes and the browser window closes automatically.what will I do?

I am facing this problem since a month.I never faced this problem before.I always feel good to use Mozilla Firefox as my browser.I used to open multiple tabs in a same browser window.For example- in a tab I logged in to Facebook,at same time I might be downloading songs or something else or open another site in the other tab.It might be 2 or 3 tabs sometimes.But now a days,I am facing the problem whenever I open multiple tabs.Its unusual and so much annoying.The Firefox crashes and the browser window closes showing a messege to send an error report.Please Help me.
N.B. - I am using the Windows service pack 2.
RAM - 2 GB
Hard disk MEmory - 250 GB.

I had this same problem. Seems to be caused by the web developer tool bar FF extension (this started happening after a recent update to that extension). After disabling it, my FF is back to normal :)

When ever I customize the toolbar the open new tab sign that is the + sign near the lastly opened tab in the tab bar disappears and it remains so even after restarting Firefox.

When ever I customize the toolbar, the open new tab sign that is the + sign near the lastly opened tab in the tab bar disappears and it remains so even after restarting Firefox. This happens only after updating to the new version 4.0.1 it never happened in the older versions 3.x.xx- checked it thrice. Thought it could be a bug and i didn't know where to report also don't have time and patience to search for the appropriate page so i'm reporting here for improving my favorite browser.

You can find the New Tab button showing as a '+' on the Tab bar. 
You can open the Customize window and drag the New Tab button from the Tab bar on another toolbar and it will become a regular toolbar button like the New Tab button that you have in Firefox 3 versions. 
If you want the New Tab button at the far right end of the Tab bar then place a flexible to the left of it.

I figured it out!
I read a solution for something that sounded similar.
Anyone in similar position:
Open iTunes app on iPhone, and pick an option from bottom, such as music. Then scroll down to bottom of page and where your iTunes ID is, press on it, and pick sign out.
Then return to home screen, and double press home button and press and hold on first icon showing, until a minus symbol appears in the top left of icons present. Press on each minus symbol on each app in turn, until all app icons have disappeared. Then Restart the phone by pressing and hold the home button and the on/off/standby button at top of phone, until the apple symbol appears in centre of blank screen.
Swipe to turn phone fully on and open settings and scroll down to iTunes and apps option and tap that. Pick sign in and put in your apple ID, it will accept it and then return to home screen and open iTunes a you'll find it works fine
Simple really, but some like me won't think f this themselves!
Hope that helps

The red, green and yellow buttons in the upper left corner of the screen disappear whenever I open Safari. I cannot minimize the Safari window which I often need to do if I am coordinating multiple windows. Does anyone know how to get those buttons back

The red, green and yellow buttons in the upper left corner of the screen disappear whenever I open Safari. I cannot minimize the Safari window which I often need to do if I am coordinating multiple windows between different applications. Does anyone know how to get those buttons back? I guess I could just switch betwen appliations, but I am used to doing it the other way.

You're welcome
You had Safari in full screen mode.

Running a presentation via VGA out with Firefox/Safari open. When I hit 'esc' to come out of slideshow, monitor stated resolution too low. Now Safari and Firefox browsers are still open, but I can't see the browser window on either. Ideas?

If you use Lion, go to Applications/ Mission Control and, if you have more Desktops, as attached, it means you have more, and you must select the one you need for a certain app. If default settings has not changed, this is Control with left / right arrow
If in Snow Leopard and earlier, you have these settings in System Preferences only. In Lion, you also have some settings in Sys Prefs.

My Firefox can no longer open new tabs. I click the icon but it does not work. How can I fix this?

The "+" icon that opens new tabs does not open a tab.

With Firefox version 4 and 5, the default setting is ''not'' to ask the question for saving the session. You can get back that behavior by modifying the options as below: 
# In the address bar, type '''about:config''' and press Enter.
# Accept the warning message that appears, you will be taken to a list of options.
# In the '''Filter''' textbox at the top, type '''browser.tabs.warnOnClose'''
# You will be presented with the entry for '''browser.tabs.warnOnClose'''. If its value is set to '''false''', double-click on it to change its value to '''true'''.
# Repeat these steps for options''' browser.warnOnQuit''', '''browser.warnOnRestart''' and '''browser.showQuitWarning''' and set their values to '''true'''.

Navigation bar opens new tabs for links on the same site - only newer versions of FireFox does this! Why?

I've used this custom navigation bar for nearly a decade. New versions of FireFox open new tabs when I navigate to different pages on my weather site. Very annoying!!! I've tried turning off tabs, but then it opens NEW WINDOWS! These links ARE NOT ENCODED TO OPEN IN NEW WINDOWS! What is causing this? Looks like I"m going to have to switch to Chrome or go back to IE, since nobody at Mozilla seems to care about this. They seem to think it is a good feature and not a bug. What gave you the right to decide to open new tabs at random times? If I click a link on a site that is on the same site I'm already on, and the link isn't coded for _blank, then it should open in the same window!

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 can I put the "open new tab" button back to the right of the right most tab in FF 4?

It's very annoying to have to go up to the corner to click on the open new tab button when it used to be to the right of the right most tab. I have other buttons, like print up there and have to think about which one to click. What was wrong with where it was? It worked for me. At least tell me how, or allow me to change it back. It is one thing to make a product faster but allow the users to keep things in familiar places if they want. I've liked that option on Firefox with most things. I've been a Minefield then Shiretoko user for a number of years an I think I will stick with it for the foreseeable future.

Thanks. I don't know why it wouldn't just go back there when I tried putting it back? I didn't change anything, so I assumed the new "default" was over on the left. Glad it was a simple solution after all.

Can't open new tab by clicking on the "+" icon

I cannot launch a new tab by clicking on the "+" icon on the tab toolbar. However; if I right click it and select "new tab", then one opens
== This happened ==
Every time Firefox opened
== I'm not sure what caused this to happen. Only recently noticed it.

Try These Possible Solutions:
1. Restart Firefox and your computer.
2. Use the keyboard shortcut CTRL+T to open a new tab.
3. Run firefox in safemode (no add-ons) Go to start>all programs>Mozilla Firefox

When i open a new tab it continues to open new tabs until i end the session

When I try to click on something in a website and it has to open a new tab to display it the computer continues to open new tabs until i get off the internet

Specifically, which website, which web page, and which hyperlink on the webpage does that happen with?
Typically, when this problem of an endless number of tabs or windows open with a single click, there is something set to open in Firefox that really isn't something which is intended to open and be viewed in Firefox.
It might be a setting in Firefox that isn't proper or it could be the website is mis-configured, or it could be caused by an external application that has messed up a setting for Firefox or in the Registry.
Not related to this problem, but you have three different versions of Flash in your Plugins listing in More System Details.
Shockwave Flash 15.0 r0
Shockwave Flash 11.9 r900
Shockwave Flash 11.8 r800
You should remove the two older Plugins.

I can't open new tabs by clicking on the plus sign, or in file new tab

Whereas previously it was possible to open a new tab by clicking on the "plus" sign at the right of the last open tab, or by selecting "file" and "new tab", neither of these options work. New tabs will open for a new webpage, but a "blank" will not appear.

Opening new tab does not display my home page by default, what setting do I change to achieve this?

When selecting the open new tab option, in the past, the tab opened displaying my designated home page. It now opens displaying a YAHOO! search page. My home page settings have not changed and continue to display the correct address, selecting 'home' brings up the correct home page, at any time during browsing. Is there another location where this 'invalid' new tab address might be listed, and removed or reset ?

VC you are a genius! I solved my problem with your solution.
Thanks a lot!
