• Firefox does not, despite having worked before, and I can not install or uninstall upgrades.

  Using Windows 7 Home Premium - have not had a problem prior to the opening of Firefox, but now it does not open. When I try to uninstall or install the update I get the message that I need to first close Firefox - it does not run and I rebooted and use management tasks without success.

I used Windows XP Add Remove programs who asked if I wanted to save the settings of Firefox until I uninstalled Firefox. I said yes and operated with the uninstall.

• Firefox does not fill automatic password which he saved?

  It is a strange problem I have met only on a few sites. Always happens on a specific site of the game (quakelive.com).

  In any case, I have my password for my registered account. When I connect, however, Firefox does not automatically fill in the login or password fields. If I go the login, it still does not automatically fill in the password field. I know that Firefox is the password, because if I go that wrong (as I often do), I get a window pop up with something like "would you like to update the saved password on...? Well, no, Mr. Firefox, I would not be updated, but I * would * like you to fill if you (what you do).

  I've checked and checked all the basics in other articles; I'm pretty confident that all my security settings and password are correct. I rarely problems on other sites, even if I can remember what happens elsewhere before (quakelive seems to be the main culprit here, and it may be a specific problem with this site). I can always go in password manager and find it, but that kind of defeats the purpose.

  Any ideas?

  I believe that this is caused by the site, some Web sites may voluntarily make sure you can't use her AutoFill, it is usually for reasons of security or anti spam measures.

• Firefox does not load.

  Firefox does not load. I have installed Kaspersky Internet Security and everything was working fine until it wasn't. I then uninstalled Kaspersky, but Firefox still load.

  Since I love Firefox I restored my computer to an earlier state and that fixed everything, then I installed another Kaspersky product and everything was perfect. Now the problem is back.

  I don't know if the problem is on the side of Kaspersky or Firefox, but I would prefer not to restore again and I have no more troubleshooting ideas.

  Firefox starts in safe mode of Windows.
  When I double click on the Firefox icon the mouse indicates the load of the FF, but then, it does not start. Chrome starts very well.
  Contacted Kaspersky, but their first troubleshooting tip didn't work.
  Under Event Viewer, I can see the details of the accident for Firefox, but I can't read and I do not know if they are related to the FF does not.

  I'm agree with unintelligible Firefox and then put it back, but I don't want to lose my bookmarks, modules, themes, etc.

  Any ideas would be appreciated!

  You can start Firefox in its own Mode safe? Hold SHIFT and start Firefox: https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode#w_how-to-start-firefox-in-safe-mode. You could at least make backups of Mode without failure. I heard wrong with anti-banner Kaspersky features, if you can try to disable browser protection components in Kaspersky to see if he can coexist with Firefox on your system or not.

  If you need to back up things without starting Firefox, go to your profile folder http://kb.mozillazine.org/Profile_folder_-_Firefox#Windowsand copy. It must contain everything down to your history of bookmark backups and extension settings.

• I said that I have to install Chrome to place an order at Walmart. What should the Chrome that Firefox does not work?

  I have placed several orders of Wal-Mart before today using Firefox without any problems. But today, nothing but problems. I tried for more than 4 hours, get this order to cross. I told cat line of Walmart and told me that I have to install Chrome to place an order. They don't answer when I asked if Walmart belonging to Chrome.

  I deleted the cookies and cache and restarted but none of this has worked. While Chrome has that Firefox does not work? I tried Chrome before and he hated and had a devil of a time he get off my computer. I don't want to go there again.

  I have attached a copy of the message that I get seems to indicate that it is a problem within Wal-Mart, but I said that it was with my browser.

  I have a laptop Toshiba Satellite running Windows 7 Ultimate 64 bit and using Firefox 40.0.3.

  Any suggestions would be greatly appreciated. Thank you.

  Thanks for your reply. I just figured out the problem.

  All started when I tried to pay my order at 13:00 this afternoon. I am persistent and don't give up easily. Five hours later, I found an error in their programming, which allowed me to add an item to my shopping cart that was a purchase in store only. But then when I went to pay for it, he became confused and wouldn't let me order but didn't tell me why.

  I solved by moving all items in the basket to saved for later and then add one at a time, trying to get to the car after each addition. It took a while because there are 20 items. He had the same problem when I added the item in the store to the cart and tried to pay for it. So I deleted and purchased on Ebay.

  Now I know probably as much if not more than any of their populations of the Chat line that can only be read on a book script.

  It's a relief that I don't have to use Chrome. I really like Firefox and would not change.

• Flash for firefox does not work

  I checked my computer and it says that flash works but when I go to play games I can't because msg says I need Flash. I've always been able to play the same games before now I can't. all parameters have remained the same, why is today different?

  When you are on the site where the game does not load, do you see a notification icon in the address bar?

  Notification plugin icon looks like a small Lego block, usually dark gray. If you click on it, it should tell you if the Flash is allowed for the page or if you need to.

  If the icon does not appear, Firefox does not recognize the code in the page. If it appears, and Flash is allowed, then the page may have a difficult time in commissioning.

  There is a problem with some Flash games does not not in Firefox 40. To see if the game you are playing is affected by this issue (asynchronous loading), you can try this modification of the parameters:

  (1) in a new tab, type or paste Subject: config in the address bar and press enter/return. Click on the button promising to be careful.

  (2) in the search above the list box, type or paste the IPC and pause while the list is filtered

  (3) double-click the preference dom.ipc.plugins.asyncInit to change its value from true to false

  I don't know which begins to take effect immediately, or if you leave Firefox and start it again.

  Return to the page with the game, then reload the page (you can click on the circular arrow in the address bar) to see if it will work now.

  A little luck?

• Firefox does not start after the places.sqlite opening in Notepad

  Firefox does not load again. I tried to create a large folder of bookmarks, but I wanted them to hide so I tried to be clever and create a copy of my current places.sqlite who had no bookmarks added and moved elsewhere, then I added bookmarks and once that replace the current places.sqlite then I created a copy of this and put it elsewhere for more security and then I replaced it with the first places.sqlite I had copied. I had to go through that much trouble because for reasons, I was unable to delete the bookmarks by right-clicking and selecting delete. I had already tried to open places.sqlite in Notepad and since then is when it started to happen. I tried to reset the file extension type, or rather detached, but I can't figure out how. I also tried to remove completely any Mozilla partner, restarted my computer and then reinstall Mozilla, but it didn't work and I prefer not to try again or uninstall it because my computer has a very difficult time even boot Windows 10. He likes to get on the desktop and then never hang while I have to restart the computer continuously until it works.

  Can someone tell me what to do or where it is that I was wrong?

  Hello

  Try Firefox Safe mode to see if the problem goes away. Firefox Safe mode is a troubleshooting mode that temporarily disables hardware acceleration, restores some settings and disables add-ons (extensions and themes).

  If Firefox does not work, you can start Firefox in Mode safe as follows:

  • On Windows: Hold down the SHIFT key when you open the desktop Firefox or shortcut in the start menu.

  When the Firefox Safe Mode window appears, select "start mode safe."

  

  If the problem is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme or hardware acceleration. Please follow the steps described in the section Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems to find the cause.

  To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

• Firefox does not (no message). Firefox used to uninstall (no message)

  Firefox does not start. The hourglass appears momentarily, then disappears followed by effect of its development. There is no error message. The Task Manager is never loaded Firefox.
  Then when I try to uninstall Firefox, when I click on Remove, new hourglass appears momentarily, then silently disappears. I am running Windows XP.

  (If you are using an additional theme, place you in default theme.)

  If Firefox is not running, you can start Firefox in Mode safe mode as follows:

  • On Windows: Hold down the SHIFT key when you open the desktop Firefox or shortcut in the start menu.
  • On Mac: Hold the option key during the startup of Firefox.
  • On Linux: Exit Firefox, go to your Terminal and run firefox-safe-mode
    (you may need to specify the installation path of Firefox for example/usr/lib/firefox)

  Once you get the pop-up, simply select "" boot mode safe. "

  To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

• Firefox does not remove expired cookies

  I thought that all expired cookies should be removed automatically by the browser. but this isn't the way it happens in my Firefox (same behavior for different web sites).

  close Firefox and even restarting the computer didn't help.
  the only way to remove cookies expired since Firefox is: hand (which means I have to choose cookie in the privacy of the Firefox Options tab, and then press the 'Delete cookies' button).

  Well, the good news: expired cookies are ignored by the servers (tested with a user through my virtual server script), but for some unknown reason continue to be stored off in Firefox.

  Is it the way it should work?

  Between the bug reports, it seems that Firefox does not remove expired cookies automatically. This only happens if you exceed the maximum storage limit of 3000 cookies. Deletion of expired cookies seems to be something that would have to do in time of inactivity, because he made a start or close does not adversely affect performance.

• Impossible to load profile, the Profile Manager are not available, firefox does not

  It is somewhat similar to the other listed problems with Profile Manager, but none of the answers worked for me. OS is Win 8-64 bit. Have 2 user accounts. Admin and Limited. In Admin, Firefox works, can access the Profile Manager, there's this profile.ini etc. All right.

  But in the limited account cannot access Firefox. When you click it, it says "Firefox your profile cannot be loaded. It may be missing or inaccessible. Can't access the Profile Manager "C:\Program Files (x 86) \Mozilla"-p. gives the same error message (Firefox does not).

  Tried to copy the files in the Admin in Limited. But the error message is the same.

  Uninstalled and installed using the limited account (supply Admin password), no result.

  Please help me.

  Thank you for your time.

  Hi Cor - el, ideato,
  Thanks for the support.
  When I entered the command, it gave me the error "the file name, directory name or volume label syntax is incorrect."

  I tried the command in different ways, but the results were similar.

  When I tried in the Admin account, it worked. But not in Limited account.

  In any case, after a long period of time, I managed to solve the problem (well sort of).

  That's what I did;
  1 uninstalled Firefox from Windows Add/Remove programs
  2. manually deleted all the files that were there for Firefox.
  3 created new account limited ('Test')
  4. sign in to that account and then close.
  5 installed Firefox using the Admin account.

  She's. Inside this 'Test' (limited), Firefox works fine. Unfortunately, inside 'Limited' Firefox is still inaccessible. But it doesn't matter. What I need to work Firefox in a limited account. I can remove 'Limited' and rename the 'Test' in 'Limited '.

  Thank you for your continued support. I learned a lot from your instructions!

  Happy troubleshooting!

  Thank you and best regards!
