It is possible that Firefox isn't closing properly
See:
*"Hang at exit": http://kb.mozillazine.org/Firefox_hangs
*"Firefox hangs when you quit it": https://support.mozilla.org/kb/Firefox+hangs
Use "Firefox/File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit") to close Firefox if you are currently doing that by clicking the close X on the title bar.

On Mac OS X snow leopard, when I quit firefox 4, all the app tabs I set up get deleted. Is that suppose to happen? on your website it says that when you close firefox and reload the browser the app tabs should be there on start up?

When I close the firefox browser but I do not quit the program entirely, the app tabs remain as I had originally set them up.
But when I fully quit firefox. All the app tabs I set up are gone and I have to set them up all over again every time.

Here's what happened in safe boot mode.
I click on apple logo > software update > see's that Super Drive 3.0 is checked > click install
I wait for the install to go through.
First pop up says " There was a problem installing this update" Quit all apps before installing bla bla bla... I noticed a sound when this pop up appeared. It's the sound of when you restart the macbok. There is another popup behind this saying that software update has been sucessfully installed.
So what I did first was click "quit" on the popup saying "There was a problem installing this update".
then I clicked "ok" where it said that the software installation update was successfully installed.
I get another pop up which is the Software Update window. I let it look for any updates and it then says that my software is up to date. I noticed that Super Drive 3.0 is listed and cannot be checked [x]. There's a Check mark with a green circle around it.
I quit the software update window and click on apple logo > software update and let it do its thing. Next thing you know, It says that Super Drive 3.0 needs to be updated. I also checked the SERIAL ATA and still shows rev. CP06.
I just recently installed this mac os X so there is no "important" data on this laptop. I don't have any money for OS Lion or Mavrick nor meet the system req to run it. 2gb to 4gb is expensive for a ddr2 800 200 pin ram

When asking for username and password the default username is wrong

I have had a look through all the posts here but I can't find anything that helps me. I don't want to actually change my username or reset my password. I know what they both are; however...
I have a recently had to replace my hard drive and now have a fresh install of Snow Leopard. When installing programs the typical enter username and password box pops up but the default username which is populated there is wrong. I have to change it every time before I enter my password. I don't know why this is happening all of a sudden.
For example my username is xxxxyyyy but it comes up as Xxxx Yyyy (note the space). If I enter my password without changing it it gives me an error. If I enter it correctly everything works fine.
This is more of an annoyance than anything. Where/how do I change the default username that is entered into that box.
Any help would be much appreciated.

I was able to change the default account login on my mac --
Go to System Preferences => System => Accounts & click on the lock to make changes.
Highlight the account you want to change & click on the Password tab on the right.
In the box that says Full Name type in your name the way you want it and hit enter.
Reboot you mac.
Your changed name should now be listed as default.

I only have one tab open but when I close firefox I get the notification that I am about to close 5 tabs. I can not see these other tabs.

First it started out as just 1 extra tab. Then it was 3 and now it's 5 tabs. But there is only one tab open and I checked for pinning and an extra window open.

It's possible you have a second ''tab group''. This article describes the concept: [[Use Tab Groups to organize a lot of tabs]].
To work with the tab groups in the current window, press Ctrl+Shift+e or look for a menu button toward the far right end of the tab bar. If you find multiple tab groups, you should be able to drag all the tabs into a single group so you can work with that one group and see what is getting closed.
I don't use this feature myself, so if that doesn't work, hopefully another volunteer can provide a better set of steps.

No. It's the Gatekeeper feature in Apple's OS X operating system asking if the software is trustworthy and should be installed.

What's the difference between keep cookies until I close firefox and clear cookie history when firefox closes?

In the settings for Firefox 33.0 (I am using Ubuntu 14.04 but the functionality is the same for Windows 7) there are two different ways to delete cookies when firefox closes. Or at least there seems to be.
First is the keep cookies until firefox closes
Second is to check the box to clear history when firefox closes and in the settings check cookies.
What is the difference between these two options?
I usually have both setup but I was noticing that a login was not saving for td canada trust easyweb, even though I have an exception set for it. Now I unchecked to delete cookies when clearing the history on close and the login saves correctly.
This login saves 7 cookes under easyweb.td.com and 10 cookies under td.com and I have exceptions set for both. If I clear history on close and include cookies, half of the td.com cookies are gone when I close firefox and re-open. The same is true if I don't set the exception.
So currently I cannot figure out a way to keep all the cookies if I clear cookie history when firefox closes. What is the difference when this is enabled?

Let all cookies expire when Firefox is closed to make them session cookies.
*Firefox/Tools > Options > Privacy > "Use custom settings for history" > Cookies: Keep until: "I close Firefox"
Create a cookie 'allow' exception for cookies that you would like to keep.
*Firefox/Tools > Options > Privacy > "Use custom settings for history" > Cookies: Exceptions
Clearing "Site Preferences" clears all exceptions for cookies, images, pop-up windows, software installation, passwords, and other website specific data.
Clearing cookies will remove all specified (selected) cookies including cookies with an allow exception that you would like to keep.

I have to shut down my computer and restart to get into Firefox again. If I can't get this fixed I will start using someone else. Someone told me a way to close Firefox but I forgot what they said.

Hello Brian.
You don't need to restart your computer to open Firefox again: you just need to close it manually through your application manager (CTRL+SHIFT+ESC in Processes tab). Anyway, hopefully this support article is what you need:
http://support.mozilla.com/en-US/kb/Firefox+hangs
What's probably happening is that you may be having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
Whenever you have a problem with Firefox, whatever it is, you should make sure it's not coming from one of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] and select ''Disable all add-ons''. If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and theme. You can troubleshoot plugins the same way.
If you want support for one of your add-ons, you'll need to contact its author.

Firefox is freezing. When I close Firefox, and try to re-start it, it will not open. I need to access Task Manager, where I find Firefox still running. I close Firefox in Task Manager & can re-start Firefox.

Firefox is freezing in the middle of a browsing session. When I close Firefox, and try to re-start it, it will not open. I need to access Task Manager, where I find Firefox to still be running. Once I close Firefox in Task Manager, I can re-start Firefox. This can happen several times in the space of a few hours? I'm running Vista Home premium with Firefox 3.6.16, and this problem has only started in the last 4 weeks. Can Anyone Help? Core 2 Duo E7300 with 4GB RAM.

Sounds like it is hanging when you exit and later try to restart Firefox.

When I close out and try to come back on I am told that Firefox is still running, close it out. How can I close it out again...

When I am on the computer, and close out, sometimes I need to get back on. When I try to do so, I am told that Firefox is already running, close it out or restart. This is not right, and it should not be. Why can't I get back on line?

Sounds like it is hanging when you exit and later try to restart Firefox. Generally, the cause is an Extension or a Plugin.

FF doesn't open a new window , and doesn't open at all when I close it and try to open it again.

Initially when I start my PC Windows 7 Ultimate , FF opens fine , but it doesn't open a new window when I click on the option "Open a new Window " in the taskbar .When I right-click a tab and select the option "Move to a new Window" then too it doesn't work. Next when I close FF and and try to reopen it , it doesn't open at all.I have FF v34.0.5.

Gnome-shell issue. You can disable desktop management as a temporary fix, but the next gnome-shell update will fix the problem.

Make sure that you do not use "Clear Recent History" to clear the 'Browsing History' when you close Firefox or use cleanup software that clears session data (sessionstore.js)

Hi Andis.
First of all, this is completely normal behavior, although it's a bit irritating, I know. What happens is that when you close Firefox, despite the window disappearing right there and then, Firefox keeps running for a little bit until the whole closing procedure is completed. This can take a fraction of a second on fast computers, or can take a few seconds on slow computers or when Firefox is storing a large session (if you save your tabs). All you have to do is wait a bit until Firefox closes, and then open it again.
To see if it's still running, you can press CTRL+SHIFT+ESC and then, under the Processes tab, you can see if firefox.exe is still there. If it's taking an unusual amount of time to close (which happens very rarely, and only if the browser freezes on exit), you can force the application to terminate from this application (task manager).
Firefox 4.0 will reduce by 97% the time it takes firefox.exe to close, so this problem will be basically erased for Firefox's next version.
Until then, I can recommend you this extension, which helps you restart your browser more easily and without bothering about closing times:
https://addons.mozilla.org/en-US/firefox/addon/3559/
Hopefully this will help.

In iPhoto if I select View, then Sort Photos by title, how do I stop it reverting to sorting by date when I close iPhoto and re-open it later?

In iPhoto if I select View, then Sort Photos by title, how do I stop it reverting to sorting by date when I close iPhoto and re-open it later?

In what mode, Events, Photos or in an Album, are you when you select View ➙ Sort ➙ By Title?
As a first fix attempt try the following:
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
User/Home/Library/ Preferences folder.
2 - delete iPhoto's cache file, Cache.db, that is located in your
User/Home/Library/Caches/com.apple.iPhoto folder (Snow Leopard and Earlier).
or with Mt. Lion from the User/Library/Containers/com.apple.iPhoto/
Data/Library/Caches/com.apple.iPhoto folder
3 - launch iPhoto and try again.
NOTE 1: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto. You'll also have to reset the iPhoto's various preferences.
NOTE 2: In Lion and Mountain Lion the Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.
