When I try to open Firefox, it flashes open and closes. Second try opens OK.

I have a quick launch icon I use to open Firefox. When I click on it, Firefox opens for about 1 second and closes. I click the second time, it opens fine.

Sorry, Firefox 4 beta 1 is not compatible with the Samsung Intercept. For details, see: https://wiki.mozilla.org/Mobile/Platforms/Android#System_Requirements

When I try to open firefox nothing happens, the browser window won't open. How do I fix this?

My firefox browser won't open. It looks like it's working, but then it just stops.

Hi prubright, '''try Firefox Safe Mode''' to see if you can start firefox with that way. [[Troubleshoot Firefox issues using Safe Mode|Firefox Safe Mode]] is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).
Try to start Firefox in Safe Mode as follows onWindows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
When the Firefox Safe Mode window appears, select "Start in Safe Mode".

'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] article to find the cause.
''To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
'''otherwise''', try to boot the computer in [http://windows.microsoft.com/en-us/windows/start-computer-safe-mode#start-computer-safe-mode=windows-7 Windows Safe Mode with network support] (press F8 on the boot screen) and then see if that allows to start firefox.
thank you

When I tried to open firefox nothing happens. I was able to open another type of browser but not firefox.

Firefox suddenly closed on me while trying to browse a page. When I tried to reopen it nothing happend. I even tried launching from the task manager Nothing. I have loged off and restarted my computer and uninstalled and reinstalled firefox. Still nothing. It's not my internet because I'm browsing fine on explorer. Firefox is my favorite browser and i would hate to not have it but if it does not work I will have to change browsers.

All that comes up when I open Firefox are my toolbars and a place to enter a URL, but there is no window. I have to enter full screen mode to view websites.

Something happened with Firefox where all that comes up when I open Firefox are my toolbars and a place to enter a URL, but there is no window. I have to enter full screen mode to view websites. How do I get back to a regular browsing window? I have no idea how this even happened.

Hello,
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.
Did this fix your problems? Please report back to us!
Thank you.

When I click to open Firefox, iTunes launches instead, and no Firefox browser window appears.

When I click to open Firefox, iTunes launches instead, and no Firefox browser window appears.

Actually... I take it back. I TRIED to update to 16.0.2, but I keep getting the error message that Firefox must be closed first. I'm using Chrome to send these messages, and have also closed iTunes, in case that was contributing to the problem. No use... I can't install the upgrade.
HELP!

The books are all in my library but when I try to open them the app glitches and closes out.

I have an iPod 4g and I had deleted the ibooks app but downloaded it again. The books are all in my library but when I try to open them the app glitches and closes out. Before the app update (ios 7) and after the update it hadn't worked (for the past week).

I think I have found an answer on another page! If anyone else wants to know just do this:
Hold down the home and sleep button (if the turn off button comes up just ignore it) and when you see the apple logo release the buttons and let it wake up!
It worked for me and seem to work for a lot of people. Hope this helps!!

FF31: When I only have one tab open, even a blank one, and close the tab the window closes.

FF31: When I only have one tab open, even a blank one, and close the tab the window closes.

Type '''about:config''' in the Location bar and hit '''''Enter'''''.
''Accept the warning.''
'''browser.tabs.closeWindowWithLastTab'''
double-click to toggle to '''false''' and then restart Firefox.
Now if you close the last tab the window (or Firefox) won't close, but a New Tab will be there.

I get above message when I click on the firefox icon.

This worked, I used the method described in this link http://forums.mozillazine.org/viewtopic.php?t=365156, and opened the Mozilla profile screen with the terminal on my mac, using the language given in the links. Then I duplicated my original profile to save the bookmarks, etc. Put them in a folder listed Duplicate profile with the date. With the open profile screen, I deleted my original profile, created new profile folder and then a new profile. Note that profile cannot be created in the system library, it must be created on the disc, because the library will not allow writing into it. After I created my new profile folder, I dragged all my old information into it, and it worked. Firefox closed and the error disappeared. You must be VERY careful to make sure Firefox is closed anytime you are doing anything with the profile folders. I think that is what caused my original problem.

When I clear my history, Firefox clears my browsing and download history even though this checkbox is not checked. It didn't use to do this. What can I do to fix this?

When I clear my history, Firefox clears my browsing and download history even though this checkbox is not checked. It didn't use to do this. What can I do to fix this? I believe the problem started with the last Firefox update.

Do you mean the "Form autocomplete" feature?
