Prevent windows closing when tabs are open

Safari closes windows without warning even when multiple tabs are open. This is even more of a problem with the Close button just above the Back button (I tend toward mouse vs keyboard control). I know this has been discussed before, but the solutions either aren't currently available (Taboo) or no longer seem to have the warning tool (Safari Enhancer).
Can Safari do this on it's own (issue a warning before closing pages with multiple tabs open)? If so, how? If not, anyone have a solution?
Thanks,
Carl

Hi Carl
3rd party add-on SAFT has a close window warning as one of its many features. This same feature is also available in Safari 3 Beta via the Safari Preferences>Tab panel. Beta 3 could be installed on your MacBook (requires either 10.4.9 or 10.4.10), but not the other machine.
Beta 3 is available here. If you decide to try it, do not use the computer during the install. After the restart Safari 3 will be in your applications folder. If you use any 3rd party items, such as SafariPlus, SAFT, etc. make sure you have the latest version installed. Same with Adobe Reader (8.1) and Flash (at least 9.0.28).
If you decide to uninstall the Beta, there is an Uninstaller in the Installation package. This is the only way to safely revert back to Safari 2.0.4.

when two or more tabs are opened after this when I click on another tab which is opened then firefox stopped responding and open automatically all the tabs in different windows

If it works in a new window then you can drags tabs from the not working window to that new window.
You can also try to close the tabs via Ctrl+W and restore the closed tabs via Shift+Ctrl+T

When I open itunes I get a 'DATA EXECUTION PREVENTION' 'Windows closed program'. Can anybody help please.

When open iTunes it starts OK then a message from Windows appears, 'DATA EXECUTION PREVENTION Windows closed program'. Then the whole thing shuts down. Does anybody know how to sort this out please. I am using XP operating system and have recently updated iTunes. Thanks

Hi alanfromharlow,
It sounds as if iTunes is failing to launch properly on your Windows computer. You don’t mention what version of Windows you have, but one of these two articles should be useful to you -

Firefox doesnt load an image when *lots* of tabs are open

Hi,
An old website I created has a problem displaying a very large background image when *loads* of tabs are open (which makes me think its something to do with memory).
An example page of the site in question is:
http://www.southbankcentre.co.uk/about-us
The white background image (which is super large for reasons not to discuss now) will show fine when, say, up to 10 tabs are open. However, if you have loads and loads of tabs open, this image doesn't display/render (even though firebug says it has).
Some info about the image:
http://www.southbankcentre.co.uk/sites/all/themes/southbank-centre/images/template-3-col.png
79.6kb
940px by 23000px (super huge I know)
The problem is when it doesnt load, the copy is hard to read (as you can imagine).
This doesnt seem unique to my computer. It happens to other peoples firefox browsers (and they have slightly different versions and different plug-ins).

I'm not having any problems on that page with over 80 tabs open and the number of tabs shouldn't matter.
Did you check if you can reproduce it with a clean new profile without extensions?
Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.

A lot of memory is used when multiple tabs are open

Is there anything that can be done about the insane memory usage in Firefox when multiple tabs are open? I often have 20+ tabs open and the amount of RAM that Firefox uses when I have it open with this many tabs is just ridiculous. As an example of this, I just restarted Firefox after checking the Windows Task Manager. The Task manager said that Firefox was using 1.2 GB of RAM. I did have 32 tabs open, but this seems excessive even for this many tabs. Some of the tabs were image heavy, but none of them had any video in them. I'd think 10 MB per tab of RAM would be plenty to cover these kinds of pages, maybe 20 MB at most. The upper end of that range would be 640 MB of RAM. Instead, it appears to be using an average of 40 MB of RAM per page when this many tabs are open.
Is there anything that can be done to reduce amount of memory being used when multiple tabs are open? It really shouldn't need this much RAM to serve this many pages.

Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> 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

After Installing Bitdefender 2011 Firefox is very slow and worse when multiple tabs are open

Firefox performs very poorly after I installed Bitdefender 2011. There was no such problem with Bitdefender 2009. When multiple tabs are open, switching between them is not possible until tab contents are completed.

As ninjafox says, the problem seems to be the BitDefender Anti-phishing Toolbar. Disabling this through Tools -> Add-ons and restarting Firefox seems to fix the problem for that session. However, the problem then reappears when the computer is restarted, presumably because BitDefender re-enables the toolbar.
Another way of disabling all add-ons when starting Firefox is to hold down Shift while clicking on the icon (Windows only I think - at least doesn't work on Ubuntu for me).

Firefox crashes when i clear recent history if multiple tabs are open, is anyone else experiencing this?

Firefox crashes (hangs, requires me to force close, and then doesn't actually clear the history) when i clear recent history if multiple tabs are open, i do this so i only lose the history and can maintain the tabs i want for the next session.
I have always done this in Versions 3 without an issue, since moving to Version 4 it happens semi regularly. the more tabs i have open the higher the likelyhood of an error
is anyone else experiencing this?
Windows 7 pro sp1
firefox 4
addons: no script, adblock, pterodactl, imagezoom, reddit reveal, java, tinyeye, better privacy.

This happens to me too. OS winXP home.

Safari warning before quitting when multiple tabs are open?

I'm a rather clumsy typist who often uses Apple+Tab to toggle through my open programs. This works great 99% of the time, but that other 1% is rather frustrating considering that the Q key is right next to Tab.
Apple guys, please implement a pop up/drop down warning when attempting to quit Safari when multiple tabs are open (or at least the option to enable or disable it). I use this browser for work and often have many tabs open, so accidentally quitting the browser only impedes on my workday. I know I should be more accurate, but isn't that what part of progress is? The empowerment of laziness? =)
Thanks for your time, and hopefully we see this included in soon-to-come upgrades!
Oh, and if this feature is already available, feel free to show me the way.

jefftovar,
I created and modified the Safari Keyboard Shortcut
Quit (⌘+Q) command to (⌘ControlQ) by using System
Preferences...>Keyboard Shortcuts.
;~)
Great suggestion! But, the default Quit (⌘+Q) command is still in effect. I've looked about in trying to deactivate it, but can't seem to find it. How did you get rid of yours?

When I am trying to open multiple tabs by clicking on File- New Tab, no additional tabs are opening i.e. I cannot open multiple tabs in my browser..Please help..

I am unable to use the multiple tabs option in my firefox browser. When I am clicking on File->New Tab no additional tabs are opening..

The Ask Toolbar is causing that in the Firefox 3.6.13 version. Evidently something in that extension isn't compatible with a Firefox security fix. Disable that extension or un-install it.

Invisible windows appears when trying to open a new window. These windows are listed in the Window list, but I cannot switch to them or close them. This also occurs when I try to "View Source". This was not a problem prior to my 6.0 upgrade.

The Downloads Window cannot be accessed either.
This is very annoying. Is this a bug? Or is there a fix.

If anyone is reading this still looking for what caused the issue and how to fix it here is what I discovered.
The antivirus program our company uses, Bitdefender Antivirus Plus, was causing some of the PDF files not to open. After troubleshooting the different modules and settings the culprit was..
Scan SSL in Privacy Control Settings. Turning it OFF solved the problem and all the PDF files that previously would not open now open just fine. This issue has been sent to Bitdefender for them to review. If you use a different antivirus program and are having this issue try locating the Scan SSL setting and see if turning it off solves the problem.

When using Tab Groups, is less power/memory used or is it the same as when all the tabs are opened in the task bar?

When using Tab Groups, is less power/memory used or is it the same as when all the tabs are opened in the task bar?

it's just another View for your tabs which needs less *space* in the taskbar, but same *memory* of your computer.
exception: if you (re)start FF and restore the last session (with lots of tabs/groups) there is an option in FF-Settings to load the (content of the) tabs only as soon as they are clicked, and not as soon as FF starts. That trick saves memory.

How do I control how where tabs are opened?

Is there a way to control how new tabs are opened in Firefox? Currently, when I click on either the "New Tab" button or the "+" button, new tabs are opened to the far right of all my tabs. I'd like all new tabs to open to the right of my current tab, like how links open up in my current tab if I right click and select "Open Link in New Tab".
I know there is a browser.tabs.insertRelatedAfterCurrent setting...but is there a browser.tabs.insertNewAfterCurrent setting?

Firefox 4 opens a new firefox window for every tab I open

Everytime i open Firefox 4, all my old saved tabs are opened in their own new window in addition to being put on my tab bar. Each new instance of the windows has all access to all the other tabs from the original window as well

It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
Delete the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
* Help > Troubleshooting Information > Profile Directory: Open Containing Folder
* http://kb.mozillazine.org/Profile_folder_-_Firefox
* http://kb.mozillazine.org/sessionstore.js
If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.
Deleting sessionstore.js will cause App Tabs and Tab Groups to get lost, so you will have to create them again (make a note).

Firefox 12 is very slow to load pages and if two tabs are opening it lags.

Firefox 12 is very slow to load pages and if two tabs are opening it lags. I've tried everything (e.g virus, defrag, I've created a new profile in "run", etc). I've had my router/line etc all checked and after 2 weeks of cleaning/testing etc its all pointing to Firefox as the problem. Please help as it's driving me nuts.

I have the exact same problem.
Not only does it load pages very slowly, sometimes the page will stop for a good 45 seconds and stop loading, only to finish it much later.
Something is wrong with Firefox 12, it shouldn't be this slow.
How is that each version is progressively worse than the one before it?.
Stop releasing so many versions Mozilla, release one that works and build from there.
