Why do two firefox windows open when I try to open just one?

When I start fire fox, it opens two windows.

Do you actually mean two separate windows or two tabs in the same window?
You can check for problems with the sessionstore.js and sessionstore.bak files in the Firefox profile folder that store session data.
Delete the sessionstore.js file and possible sessionstore-##.js files with a number and sessionstore.bak in the Firefox profile folder.
*Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)

Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost and you will have to recreate them (make a note or bookmark them if possible).

Why does App Store always crash when I try to open the appliction?

Why does App Store always crash when I try to open the appliction?

You don't have the typical symptoms that I associate the following issue with (normally the error kicks in just when folks visit the Store), but just in case try gn_id's suggestion from the following post:
Re: iTunes 11 crashes when opening the store - no error message

My app store will not open. when i try to open it i get an error that reads "You can't open the application App Store because it may be damaged or incomplete". How can I fix this?

I am having the exact same problem. MacForums has been helping me, and I called Apple. After trying everyone's suggestions, and Apple's, no success.
My App Store app still says "incomplete or damaged." There is even a circle with a line through it on the icon. Apple said reinstall my Snow Leopard upgrade disc (not my original Leopard disc) and then run the Combo Update (like your suggestion). Did not work. I also updated the software from "Software Update". Rebooted.
I think this started after I replaced my hard drive with a SSD and moved the hard drive to where the DVD was. I wonder if the person above who had the same problem also installed a SSD?
Anyway, anymore ideas? Even Apple is stumped.
(In answer to the other post above, my Quicktime works fine.)

Just did some more reading. I was going by the icon in the dock. When I checked in Finder, there it was, fixed and brand new!! Thanks, anyway.

Its a serious problem and many people are facing the same issue on both locked and factory unlocked phones.
I wonder when Apple will address to this issue. After all it is losing all its reputation!
See this thread, many users are encountering the same issue:

I believe its a software issue and could be solved asap Apple fixes it!

Firefox freezes sometimes when I try to open a web site in a new window.

For the past few weeks I am having an intermittent problem with firefox freezing. It happens when I try to open a site in a new window. Most of the time I have to go to task manager to close it and re-start. And almost always when I re-start it freezes for a second time and then I have to open it a third time. Usually if I try to restore a session it will happen over and over again so I have to start a new session. I have windows 7 and the latest version of firefox.

Internet Explorer opens when I try to open Firefox. No matter where I try to open Firefox, IE opens instead. Firefox is installed on my computer.

Earlier today, I accidentally uninstalled Firefox. I reinstalled it but, when I try to open it, IE opens instead. I've tried to open it from the desktop icon, the start page icon, and from the program listed on my hard drive. All of the open IE. Help!

I have tried everything I could to fix this, but some things require actually being on Firefox, and since I cannot get on, I cannot click on the tabs to do it. I have even totally uninstalled firefox, and that has not fixed this. I still get the same message that firefox is running and I need to close it or restart (which I have also tried dozens of times). I have removed things like Java, and that has not helped either. If I cannot even get on line in firefox, how can I fix this. I am not crazy about using internet explorer, but right now, it is my only option. I even tried to start in safe mode, and the same message box pops up!

Why html page opens when I try to open a document clicking on Link?

Hi,
Why a blank html page opens along with the File download diolog box when I try to open an Excel file by clicking on a Link/button (In Flash CS4). Though the html page disappears as soon as I click on "Open" or "Save" option. But It should just show the File download dialog box without an empty html file, when clicking on the link.
The following is our Intranet file path which I am using to open the Excel file:

Some folks report that some .asp does not work on the iPad. This must be one of them.

Firefox crashed now when I try to open it get Mozilla Crash Reporter

''Duplicate post, continue here - [https://support.mozilla.com/en-US/questions/788208]''
Firefox crashed unexpectedly. ow when I try to open it all I get is a Crash Reporter box. Dont have a location bar to enter a crash ID.

Try a clean (re)install:
* Download a fresh Firefox copy and save the file to the desktop.
* http://www.mozilla.com/firefox/all.html
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Don't remove personal data if you uninstall the current version.
* 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.
* It may not be necessary to create a new profile, so first try if it works with your current profile and if not then create a new profile.
Your current bookmarks and other profile data are stored elsewhere (not in the Firefox program 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.

Why does my screen go black when I try to open my videos?

When I try to open my videos, my screen goes black. All other apps work fine.

Quit the Videos app completely, restart the iPad and then try again.
Go to the home screen first by tapping the home button. Quit/close open apps by double tapping the home button and the task bar will appear with all of you recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner to close the apps. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button
If that doesn't work, try this.
Swipe to the right from your first home screen to get to the iPad Spotlight search. Type in the name of any of your movies in the field at the top. when the movie appears in the search - tap on it and it should hopefully start to play. Let it play for a minute or so - hit done - go back to videos app and see if all is OK.
And if that doesn't work, You can try this.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
