Firefox locks up when I close it, then refuses to open again until I restart my PC

Firefox refuses to open again after it freezes. This is happening every day and is fast becoming a browser that I will drop and never use again. As a long time user of Firefox I expected a more reliable product from Mozilla. The last 4 releases have been pure junk.
I'm using Windows 7 (64Bit) with 32 mg of ram. Never had a problem in the last 10 years using Firefox, but I think the time has come to switch back IE 11 which from all reports is a fast stable browser.

Same problem with FF37 beta. All internet loads stop. When I exit the program the window closes but process continues to run and Task Manager will not stop it. The only solution is to reboot. I have tried safe mode and a full refresh. Neither helps.

Browser will open once and open only one page. It closes but then won't open again. How do i fix it?

In the last 24 hours my browser will open only once and go to only one site i choose. after that , i can go to another site but links won't open or anything else. After i close the browser , so i can restart it, it tells me firefox is already open. Problem is it never shuts down in the background. I have to use the task manager to shut it off so i can open it again. Funny thing is that internet explorer, works fine but i don't want to use it. I even tried reinstalling firefox but it did not work. I had to post this on a different computer as well.

my firefox 4 beta always freez when i close it and try to open this massage show Firefox is already running, but is not responding

Delete the processes. Press: CTRL, ALT, DEL at the same time. It opens your menu asking you different selections. Just click open task manager. Click the Processes tab and press F on ur keyboard. It goes directly to Firefox, you may also have to press M to go to Mozilla Firefox, depending on how it's worded on your programs. Click end process. Then just re-open. That is how you fix it that time. Use the links on the last post about hanging to fix Firefox and learn more about hanging.

In System Prefereneces, when I am in Desktop and Screen Saver, I am unable to remove folders. I can click the "-" and the folder appears to be gone, but when I close and then reopen System Preferences, and open Desktop and Screen Saver, the folder reappears in the list. I have tried deleting preferences "plist" but I am totally unable to remove the folders.

I've seen one other report like yours, and I think the issue is caused by a bug, but I don't know what triggers it.
Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Firefox locks up when in Facebook, it has just started doing this

Firefox locks up when in Facebook, it has only just started doing this, I get (Firefox not responding) at top of page. I have tried it in IE and have no problem. I log in using Lastpass.

Start Firefox in [[Safe Mode|Safe Mode]] to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).
*Do NOT click the Reset button on the Safe Mode start window.

Note that your System Details List shows that you have a user.js file in the profile folder to initialize some prefs on each start of Firefox.
The user.js file is only present if you or other software has created it, so normally it wouldn't be there.
you can check its content with a plain text editor if you didn't create this file yourself.
The user.js file is read each time you start Firefox and initializes preferences to the value specified in this file, so preferences set via user.js can only be changed temporarily for the current session.

I downloaded pictures onto my iPhone from computer twice by mistake now when i uncheck/sync then check and sync again i keep getting two lots of pics..how can i get just the one set again? thnx

You're welcome.
All photos transferred from your computer are stored in the iPhone's Photo Library regardless if you select a single album or folder of photos to be transferred or multiple albums or folders. The photos on the albums or folders of photos include a pointer to the original photos stored in the Photo Library. The photos are not duplicated taking up double the storage space. This way you can view the photos in an album or folder of photos only by selecting the album or folder, or all photos in all albums or folders by selecting Photo Library.
Makes more sense when transferring multiple albums or folders of photos which cannot be changed when transferring only a single album or folder of photos.
The same applies with iTunes and music playlists. A song can't be in a playlist unless it is in the main iTunes library. Placing a song in a playlist does not duplicate the song.

I reset Firefox. Now when I click on the icon to open Firefox my computer asks me if I want to let Firefox make changes to my computer.

I reset Firefox. Now when I click on the icon to open Firefox my computer asks me if I want to let Firefox make changes to my computer.
I have read that I should do a clean reinstall. Will I loose all of my open tabs, bookmarks, history etc?
Is there another way to fix the problem other than a reinstall. this would have to be my last resort!

A possible cause of this error is that Firefox is set to run as Administrator.
Check that Firefox isn't set to run as Administrator.
Right-click the Firefox desktop shortcut and choose "Properties".
Make sure that all items are deselected in the "Compatibility" tab of the Properties window.
* Privilege Level: "Run this program as Administrator" should not be selected
* "Run this program in compatibility mode for:" should not be selected
Also check the Properties of the firefox.exe program in the Firefox program folder (C:\Program Files\Mozilla Firefox\).

Why does firefox stop loading then when i close it and try to open it up again I keep getting this message:Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system

Firefox will just stop loading/ connecting to the internet. The gray circle will just continually move but it never turns green to load the pages. I know it's not my internet because my internet explorer works just fine while this is happening to firefox. So I close firefox and then try to re open it but I get the message: Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system. So I wait a little bit then try and re open it and still get the same message. I then go into my windows task manager and try and end the firefox proccess but it won't end. So I restart my computer and firefox eventually starts acting up again.

For possible causes of this error, and how to troubleshoot it see [[Firefox is already running but is not responding]].

Firefox locks up when it is opened

turned on the computer last week and when I opened firefox an update quickly flashed before it opened. Then when it opened the firefox update page and my yahoo page were on separate tabs. It prompted me to continue a session or end it. At this point no matter what I do it locks up. Now days later the home page opens but lock up when I click on anything including scrolling the home page.

I have the same problem (I use IE 7 as my browser). I have had the same problem with all the versions 7.1 as well. There have been numerous posts about it and it seems that Apple does not want to fix this. I uninstalled it and reinstalled version 7.0x via

this version is once again working fine!

Firefox locks up when I try to play Pirates Rule on Facebook

Every time I try to play my favorite game "Pirates Rule" on Facebook, Firefox locks up on me and I have to restart my PC to get it to stop. I am not able to close Firefox at all once I try to load Pirates. Any idea for a fix?

'''Hangs Loading first firefox window'''
1. Right-click the shortcut icon you use to start Firefox.
2. Select Properties.
3. Select the Compatibility icon.
4. Select Run this program in compatibility mode.
5. In the drop-down for compatibility mode, select Windows 98/Windows ME.
6. Click OK.
7. Restart Firefox to see if the hanging has gone away.
'''Hang loading every Firefox window'''
The SwitchProxy Tool extension checks for updates each time a new window is opened.This is a known issue. If you use SwitchProxy Tool, you can disable it to see if hanging is prevented:
1. At the top of the Firefox windowOn the menu bar, click the Tools menu and then select Add-ons. The Add-ons dialog appears.
2. Select the Extensions panel. The list of installed extensions is displayed.
3. Select SwitchProxy Tool.
4. Click Disable.
5. From the menu at the top of the Firefox windowbar, select FileFirefox and then select the ExitQuit FirefoxQuit menu item.
6. Restart Firefox. Open several new windows to see if Firefox no longer hangs.

Firefox locks up when right-clicking and using drop-down menus

I've experienced this problem with earlier versions of Firefox as well - sometimes when right clicking (like opening up a new link) or using a drop-down menu (like in Gmail) Firefox completely locks up and I need to control all delete shut it down and restart it manually.
Any ideas?

I have a problem when i close the prgram and i open it agin it open on the page which i closed at it

when i close firefox at any page and also when i close my pc and then i open the program i find it open on last page which i closed at ,, although i made home page for it to open at and it doesn't make the order

Check in preferences > general > Startup: Do you have "Show my windows and tabs from last time" selected? If so change to "Show my home page" (or blank page).
Note: this may happen when quitting Firefox, and you inadvertently click "Save and Quit" and select "Do not ask next time".

After I close Firefox, it will not open again unless I restart my computer.

When I close Firefox normally, I cannot open it again unless I restart my computer. Why?

Yes, that is a strong indication that Firefox didn't close completely.
You can check that in the Task Manager (Ctrl+Alt+Del). 
If you see Firefox and plugin-container processes then you can close (kill) those processes and you should be able to start Firefox after having done that.
There are other things that need your attention.
Your system details list shows that you still have a very old Flash 9.0 r45 plugin installed that you should remove.
*Shockwave Flash 11.7 r700
*Shockwave Flash 9.0 r45
This plugin might be installed in the plugins folder in the Firefox program folder.
*(32 bit Windows) C:\Program Files\Mozilla Firefox\
You can set the plugin.expose_full_path pref to true on the about:config page to see the full path of enabled installed plugins on the about:plugins page.
*http://kb.mozillazine.org/about:plugins
See:
*http://kb.mozillazine.org/Issues_related_to_plugins#Identifying_installed_plugins
You can open about:xxxx pages via the location bar like you open a website.
*http://kb.mozillazine.org/about:config
It is best not to leave that pref set to true as it exposes that full path to web servers via the navigator.plugins object, so reset that pref to its default value false after you are done with the about:plugins page and have located the old Flash plugin.
