Warning When Closing Tabs

Is there a way to have a warning notification prior to closing out all tabs, when multiple tabs are open?

The prefs for the warning message have been set to false as the default in current Firefox 4 beta versions. 
[https://bugzilla.mozilla.org/show_bug.cgi?id=592822 Bug 592822] – Remove quit warning dialog ''(please do not comment in bug reports)''
You can set the warn prefs on the about:config page to true via the right-click context menu or toggle with a double left-click.

Firefox 25.0.1 Warn when closing multiple tabs (on) conflicts with "show windows und tabs from last time" (on); need both, but only one or the other works.

Using Firefox 25.0.1 on Windows 7 Home Premium
I've poured through support forums for Mozilla Firefox searching for a fix to my initial problem of the "Warn when closing multiple tabs" pop up not popping up when I have it selected.
Went through About:Config, making sure warnings for tabs und closing, und showing on quit, und quitting, etc. were all set to true, which were "possible" fixes for the issue I was having, there are like five or six things set to true for warnings/quitting/etc. No avail. They are all set to true.
Then I stumbled across one that suggested a conflict with the "Warn When Closing Multiple Tabs" und the "Show Windows und Tabs from last time".
I use both features. However, I found if I want the warning pop up for closing multiple tabs, I have to have "show homepage" or "show blank page" selected instead of "Show windows und tabs from last time" selected. (Tools>Options>General>Start Up>When Firefox Starts:) The problem with this is, yes, I get my warning pop up, BUT, I don't get my tabs from my last session.
The warning in settings (Tools>Options>Tabs>Warn Me When Closing Multiple Tabs) is checked.
To have my tabs restored from last session, I simply select it for "when firefox starts". Bam, I have my tabs that were open from the last time I quit. Und again, full circle, I don't have my warning pop up.
There were also suggestions of the warning on close for tabs is conflicting with add-ons.
However, I don't have many. Und I have yet to test them to see if they interfere. These are according to my Add Ons tab when I check it myself.
Extensions:
1. Avast WebRep (disabled)
2. HP Smart Web Printing (disabled)
Plugins:
1. Adobe Acrobat
2. Google Update
3. iTunes Application Detector
4. Java (TM) Platform SE 7 U45
5. Shockwave Flash
6. Shockwave For Director
7. Silverlight Plug-In
8. VLC Web Plugin
9. Windows Live Photo Gallery
10. Java Deployment Toolkit (disabled)
Note: The Details Firefox provides says I have these for Plugins
* Shockwave Flash 11.9 r900
* Adobe Shockwave for Director Netscape plug-in, version 12.0.5.146
* Next Generation Java Plug-in 10.45.2 for Mozilla browsers
* Google Update
* Adobe PDF Plug-In For Firefox and Netscape 11.0.05
* VLC media player Web Plugin 2.1.0
* 5.1.20913.0
* iTunes Detector Plug-in
* NPWLPG
Unsure of what the "5.1.20913.0" und the "NPWLPG" plugins are, but they don't appear to me under Add Ons.
Und as usual, I'm assuming the solution lies within About:Config, I will show here now what I have set to True.
browser.tabs.warnOnClose - True
browser.tabs.warnOnCloseOtherTabs - True
browser.tabs.warnOnOpen - True
browser.warnOnQuit - True
browser.showQuitWarning - True
As aforementioned:
The seemingly only issue is the conflict between Show Windows/Tabs From Last Time und the Warn On Quit pop up. Und again, I need/want both of them. More so the tabs from the last session, but I really really really really really want the warning.
So, if anyone knows a work around, preferably without having to download anything to fix this, I would be extremely grateful.

You mention a second subject.
''I'm probably going to downgrade to another version of firefox that was suggested to me since I'm also having issues with shockwave flash causing firefox to hang und ultimately needs to be force closed otherwise having to have flash disabled to use firefox.''
Downgrading Firefox 
Flash is notorious for causing Firefox problems. I suggest you start a new thread about that. If at all possible you should try to avoid downgrading to an unsecure & unsupported version of Firefox. it will increase risks to your system and Personal data. (There are methods of mitigating the risks, using a virtual machine or operating within a secure intranet for instance)
*(Do Not) [[Install an older version of Firefox]]
Try Flash with Protected Mode Off 
Worth a try as it takes minimal effort & often solves Flash Problems whilst allowing current and more secure FlashPlayer to be used. See
* http://kb.mozillazine.org/Flash#Flash_Player_11.3_Protected_Mode_-_Windows
* http://forums.adobe.com/thread/1018071#TemporaryWorkaround
If you wish to pursue these subjects further I note you have already started a thread you may as well continue the discussion in that thread, but also post back here so we can follow both.
* ''Firefox is having "Script" issues (Not Responding) und possibly Flash issues?'' [/questions/978181]
** try ensuring you close down Firefox using the menu, that may even help with Flash problems.
Your experience in submitting troubleshooting information on the forum 
(This is out of curiosity, but with the intention of pressing for changes if forum faults are discovered.)
There are yet more changes to this forum underway. Mozilla recently tried to improve the experience for first time users of the forum and a troubleshooting app option was included in the workflow to try to encourage users to submit full troubleshooting information.
I would be interested to know what you thought
I sometimes wonder if users are not trying to use that, or whether forum users run into problems in using it. At one point I wondered whether there was a problem if too much data was included but never actually proved that conjecture.
Assuming you are using the forum, and not merely replying by email look towards the top in the right hand margin for clickable buttons
* Question Details -V- More System Details -> [Additional System Details]
You will note that includes only partial information. There are no changed prefs or extensions listed. Compare for instance the information in this thread [/questions/978130] with full information.
I believe your mystery plugins are Windows related
* NPWLPG relates usually to Windows Live Photo Gallery
* 5.1.20913.0 will be Silverlight

Firefox 21.0 doesn't warn when closing multiple tabs

I have a Mac OS X, version 10.6.8. I'm using Firefox 21.0. I have the box checked to warn me when closing multiple tabs. It does not. Why? Is there anything I can do to make it work correctly? Any information I've been able to find on the internet is for other versions of Firefox and is of no help to me.

PROBLEM: Windows FF 21.0 warns when closing multiple tabs when ONE occurance of FF is open, but NOT when mutlipe windows are open (then it only warns once I'm down to 1 window open).
I would like a warning for ALL windows' multiple tabs. I know this is possible because that has always been the case until approx. the latest update.
Oddly enough, the only thing close I found is a post from 2011 with the exact opposite problem: warning only when multiple windows are open, but not when 1 window is open.)
SUMMARY attempts gleaned and compiled from the various posts (with no effect):
- at General tab, "Show my home page" is selected ("Show my windows and tabs from last time" is NOT selected)
-at Tabs tab, "Warn me when closing multiple tabs" is selected
- at Privacy tab, "Use custom settings for history" is selected along with "Always use private browsing mode" (is selected); however, this has always been my setting, and I've always received warnings in multiple windows until recently
- staring in Safe mode had no effect
- my about:config boolean settings are appropriately set to true/false
- I've tried restarting Firefox multiple times and restarting the computer; I have not re-installed FF nor restarted from fresh, wiping out all settings because I have so many customizations.
Any other thoughts of what I might try?

Warn when closing multiple tabs

I find it really annoying that there is not an option to warn when closing multiple tabs (as there is in Firefox). The number of times I've pressed Apple Key + Q accidently when I meant to press Apple Key + W!
I hope this will be tackled in a forthcoming release.

Firefox is not warning when closing multiple tabs, even though it is set to warn me in preferences!

Firefox is not warning when closing multiple tabs, even though it is set to warn me in preferences! Unchecking and rechecking the box does not help, it's as if Firefox is ignoring the option to warn when closing multiple tabs.

You can set the warn prefs on the about:config page to true via the right-click context menu or toggle with a double left-click.
* browser.showQuitWarning, see http://blog.zpao.com/post/3174360617/about-that-quit-dialog
* browser.tabs.warnOnClose, see http://kb.mozillazine.org/About%3Aconfig_entries
* browser.warnOnQuit , see http://kb.mozillazine.org/browser.warnOnQuit
* browser.warnOnRestart , see http://kb.mozillazine.org/browser.warnOnRestart
To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website. 
If you see a warning then you can confirm that you want to access that page. 
You can use History > Restore Previous Session to get back the previous session. 
There is also a "Restore Previous Session" button on the default about:home Home page.
Another possibility is to use:
*[http://kb.mozillazine.org/Menu_differences Firefox > Preferences] > General > Startup: "When Firefox Starts": "Show my windows and tabs from last time"

Firefox 8 and the "Warn when closing...multiple tabs" preference check box still doesn't work?

I'm aware that I can go into the about:config screen and toggle a couple of settings but the real question is "Why is this still a problem since version 4?" Why bother to have Preferences at all, if the given solution is always to tweak the config?

This hint was posted on a similar link that works for me. Here is what to do:
In option -> privacy -> choose "use custom history setting" and choose your preference for history and cookie setting. and then click "OK'.
Then you will get the warning when closing multiple tabs.
It doesn't seem to be related but it does affect the operation of the other part of the software that issues the warning.

Mountain Lion freezes for few seconds when closing tabs

Hi all,
When closing tabs on Google Chrome, usually after "heavy" navigation (HD flash video or several pdfs opened for examples), Moutain Lion sometimes freezes for less than 10 seconds and then back to normal. The trackpad is still responsive but I can't do anything appart moving the pointer. It appears around two times in one hour. In never appends with other applications like Photoshop or games.
This may be already a known issue on ML, but all the reports I read were pretty old and not exactly similar. Here some details :
Recent Mid 2012 Retina MBP (only 15 battery cycles)
Os X 10.8.2 ; 2.6Ghz ; 16GB
I *nerver* connected it to any external displays.

Those log messages indicate a fault in the graphics processor. Take the machine in for warranty service. Make sure you can reproduce the problem.

Custom plugin crashes repeatedly when closing tabs

Hello,
Our company has a custom plugin which we install onto firefox in order to connect to its API.
lately a customer complained that our plugin is crashing repeatedly. all i have to go on is this crash report for now:
https://crash-stats.mozilla.com/report/index/ff38c405-4289-4b72-a82d-fd67a2141208#rawdump
can anyone help with this?

The first crash reported seems to be crashing in visual studio. If you are using this to create a website, try a new profile to see it has to do with the interaction with your plugins. [[Use the Profile Manager to create and remove Firefox profiles]] though if they are needed, this might not work. Disable the plugin [plugin PageHook Version:6.0.0.0 Filename:nppagehook.dll ] as this was reported as the culprit of the crash.
A bug has just been filed for this the second crash and will need further investigation. However it does look like it is crashing in the plugin operation. It is it possible, can you please try to disable you plugins to see if it crashes again.
Since this also happens when closing tabs and the first crash is hanging please see these steps to prevent hangs: [[Firefox hangs or is not responding - How to fix]]

Warn me when closing multiple tabs is not checked, but I still receive the warning when closing multiple tabs

After installing Firefox 16.0.1, I always get a warning whenever I close multiple tabs, even though there is no check mark against the option, "Warn me when closing multiple tabs".

This a recent bug problem. In other versions do no exist. Some users like warnings, but others not, like me.

Yosemite - Safari still does not warn when closing multiple tabs, what will it take to get Apple to add this simple option?

I cannot understand why Apple does not add the option to warn you when closing multiple tabs. There are posts all over the Internet requesting the feature or looking for a way to do it. Why do they totally ignore this valuable, simple feature?

Thanks for the support. I guess you take one battle at at time because you hate to lose multiple battles and I picked this one. However, and this could go on quite a while, why do I have to buy another application to sort my bookmarks and have the sort sync the Cloud?. Bookmark sort - that is a programming 101 feature. Now I found that iPhoto can read AVCHD video files and Quicktime cannot. Oh my. I wish Apple would read the posts and actually take them into consideration. It would make their users feel more included. I do like Yosemite and love email markup. Good job but the customers have a few good ideas too.
At least you can Air Drop to Mac now!

Invalidate connection to BlazeDS server when closing tab in browser

There is an issue using IE and blazeds. When you establish a connection to blazeds from a tab of your browser, even when the tab get closed, she connection remains. The session doesn't get invalidated. It looks like it works fine in Firefox but it's an issue in IE.
It is especialy important if you are build a chat room for example ... you want to know precisly when someone is leaving the room.
I finally found an answer to this problem. I didn't find any answer on the Internet so I felt that I should share it.
I invalidate the session on the server side using a servlet.
Here is the code:
In my flex app html template I add:
<script langugage='javascript'>
 function disconnectAll(){
 if (navigator.appName == "Microsoft Internet Explorer")
 xhr = new ActiveXObject("Microsoft.XMLHTTP"); // Trying Internet Explorer
 else
 xhr = new XMLHttpRequest();
 if (xhr) {
 xhr.open("GET", "../disconnect", false);
 xhr.send(null);
</script>
</head>
<body scroll="no" onunload="disconnectAll()" >
This call to ../disconnect does a http request to my servlet that will invalidate the connection.
Here is the servlet code:
public class Disconnect extends HttpServlet {
 private static final long serialVersionUID = 1L;
 @Override
 public void doGet(HttpServletRequest httpRequest, HttpServletResponse response) {
 System.out.println("doGet disconnect called !");
 httpRequest.getSession().invalidate();
This has to be added in the web.xml for the servlet to be accessible:
 <servlet>
 <servlet-name>DisconnectServlet</servlet-name>
 <display-name>DisconnectServlet</display-name>
 <servlet-class>com.ms.advil.servlets.Disconnect</servlet-class>
 </servlet>
 <servlet-mapping>
 <servlet-name>DisconnectServlet</servlet-name>
 <url-pattern>/disconnect</url-pattern>
 </servlet-mapping>
That’s it ! On the unload of the page, an Ajax request is made to the servlet that will invalidate the http session.
Your browser’s connections get invalidated and blazeDS catches the disconnection.
Hope this will help
Cheers

UI Shell :Uncommitted data warning on closing tab

H experts,
My JDeveloper version is 11.1.2.1.0.
I am using UI Shell template in my application. How can i show uncommitted data warning on closing a tab using the close icon (which come with the tab by default) on the top right side.
Help me to solve this problem by sending valuable comments, links, advises...
Thanks in advance
gtg.

As per http://www.oracle.com/technetwork/issue-archive/2012/12-mar/o22adf-1518265.html , in 11.1.2.1) or later ->
Access the tab transaction state. Tabs can be marked as having their content changed, in which case they are referred to as dirty.
A warning dialog box will appear if users or the application try to close these tabs. A tab’s dirty state can be checked and manipulated with the TabContext API.Looks like this is available out of the box.

Firefox 4b10 does not warn when closing multiple tabs (setting is on).

Hey,
Firefox 4b10 won't warn me when I'm about to close multiple tabs. I have verified this setting is on multiple times.
The only reason I think this is happening is when I decided to download Firefox 3 (latest version). I installed it to see if IPTV would work on it, and decided to uninstall it. This also ended up deleting some of my addon's such as ABP.
I've tried uninstalling FF, using CCleaner and then reinstalling it.
For some reason when I install FF4, I can't seem to find the SAFE MODE option, even when I run it with "firefox -safe-mode".
Could someone help please????
Thanks. :D

The prefs for Save & Quit the warning message have been set by default to false in current Firefox 4 beta versions (Bug 592822 - Remove quit warning dialog).
You can set the warn prefs on the about:config page to true via the right-click context menu or toggle with a double left-click.
