My firefox all got completely messed up

My whole browser inexplicably got messed up.

  • Try to customize (topic: customization) does not work, click on the button of the horizontal line icon

    • gives a white on: Customizing page or
    • nothing happens.
  • Some of my modules appear active on the addons page but do not work in reality.
  • The home page that appears when I run firefox is now on: empty, although it shows my real homepage (topic: superstart) in the settings.
  • The button "Connect to synchronize" in my horizontal menu 3 lines suddenly disappeared.
  • It also appears as toggling of the modules is not really to work, because it doesn't tell me to restart firefox after trying to do so.

And many other things. How can I get it back to normal? I really hope that I don't need to reinstall firefox (I don't want to reinstall all the addons and redo all the customization and all)! I haven't done anything that would cause the bug. I just change my Windows theme and test how firefox mixed with these themes. Got deformed appearance, hanged several times, for some reason, firefox so I restarted. And then suddenly all this happens.

I really need help. Thanks in advance!

Make a copy of the profile folder may be preferable if the third-party utility does not finish the book.

In the case where one of your extensions is concerned, could test the page Firefox Safe Mode? It is a standard diagnostic tool to disable some advanced features of Firefox and extensions. More info: questions to troubleshoot Firefox in Safe Mode.

You can restart Firefox in Mode safe mode using either:

  • button "3-bar" menu > "?" button > restart with disabled modules
  • Help menu > restart with disabled modules

(Not all add-ons are disabled: Flash and other plugins still works)

If these methods don't work, the release of Firefox, and hold down the SHIFT key when you start again.

A small dialog box should appear. Click on 'Start mode safe' (not reset).

Any difference?

    Downloading Firefox, all my saved PDF documents have been turned into a Google Chrome document format, WHY? WHY a person like me is not notified before that starts the download process so that they have a chance to 'place' or 'Cancel' the download process? I want that they all be changed to PDF, HOW should I do this?

    Nothing happened to your files. The association for PDF files is messed up, or is the icon cache.

    1. Click round Windows logo in the taskbar and choose default programs.
    2. Click "associate any type of file or Protocol with a program.
    3. Select PDF from the list, then click on change program button.
    4. Choose the program that you want to manage PDF files. By clicking on the files PDF in Windows Explorer or the desktop then open them in this application.

    To clear the cache of the icon, see the directions to

    As far as I know, Firefox does not have PDF files somehow. There is a proposal to associate files PDF in Firefox when they are not already associated with an application, but has not been implemented to date (bug 787674).

  • Why my firefox all the closing hours?

    BP-56e95474-e62a-457a-B445-3903f2151110

    Could you describe the problem a little more in detail? The crash report said that there is a 'blocking' in the version of the Flash plugin. A Firefox also closed completely?

    The crash report has different extensions enabled (Gmail, Lightshot, Bugzilla Tweaks warning system) from the list in your post (see Question details > more details of the system). That looks good to you?

    You want to share other incident reports to see if they have cast additional light on the problem?

    It is a standard orientation which addresses the most common issues with the Flash Player plugin. I'm sure you've seen some of it before, but just in case:

    (1) If you have any recorders/downloaders who interact with Flash media to ensure that they are as up-to-date as possible, or disable them temporarily.

    (2) disable hardware acceleration in Flash: right click on the media in the drive and click on settings, then the first mini tab and uncheck the box to use hardware acceleration.

    More information in this article from Adobe technical support: http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_Solve_video_playback_issues

    (3) turn off mode protected (Windows Vista and later)

    The functionality of the safe_mode of the Flash player plugin has security benefits, but there seem to be some compatibility issues on some systems. You can disable it using the page modules. Either:

    • CTRL + SHIFT + a
    • "3-bar" menu button (or tools) > Add-ons

    In the left column, click on Plugins. On the right side, find 'Shockwave Flash' and click on the link for more. Then uncheck the box for "Enable Adobe Flash protected mode" and try it for a day to see if that helps you.

  • Whenever I update FireFox all my usernames and passwords vanish in password manager

    For several updates recent Firefox all my usernames and passwords (stored in password manager) disappear. I was able to recover them by exchanging one or more of the three files to a previous version ('Key3db', 'Logins.json' and 'Prefs.js') until this WHAT THE LAST THREE OR FOUR updates. This patch no longer works and I hesitate so far. I would like to know... a) this bug has been fixed?
    (b) if it is not, how can I keep my ID & password somewhere else so I can quickly re - install, or at least see them in a list so I can manually copy all back in?
    (c) how to prevent a pop-up annoying telling me to update to FireFox (other than by the update)?

    I used FireFox with happiness for many years, but this problem is very annoying and I am looking to change (with great reluctance) to another browser if an other update loses all usernames and passwords, and I have to re - install an older version to get back them.
    Please help if you can - and thank you for considering this issue.

    When I click on an image or map that is Kijiji real estate pages, open Firefox all crunched on the right side of the page. How can I fix this?
    For example, I discovered an apartment ad that has various attached photos. It said click on the images to see an enlarged version. FF opens the page however the majority of the page is white and the image seems to be pushed on the right side of the page and watch as if it were bundled up against the right side shows is not the whole picture.
    What can I do to fix this?

  • labels Firefox all tabs 'new tab '.

    labels Firefox all tabs 'New tab' - shows the favorite icon but not the domain of site

    This problem may be caused by an extension that is not working properly.

    Start Firefox in Safe Mode to check if one of the extensions (Firefox/Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox/Firefox/tools > Modules > appearance).

    • Do NOT click on the reset button on the startup window Mode safe or make changes.
  • After the upgrade of Firefox all my favorites icons disappear.

    After release of the next version of Firefox, all my favorites have lost their icons. To restore an icon I have to click this bookmark and load a web pade again. Brings back an icon.
    But I have so many icons that I can't go just by each of them.
    I appriciate any help on this matter.

    Have you tried to restore the favicons with the extension of CheckPlaces?

  • New laptop Win7; When I try to start Firefox, I get the mess, "Firefox already running" error, I uninstalled and reinstalled with the same results.

    This started after I did some of my old computer Quickbook files windows easy transfer to my laptop. I uninstalled firefox and download the latest version on the site and still get this message. I don't see where it can be run. Thnx, Bill.

    This sounds like it is not the installation of Firefox itself that is messed up, but your profile folder (where are stored the your personal settings such as bookmarks, passwords, etc.). You say you used easy transfer, and that could hurt somehow.

    To start from scratch once again, follow the instructions under "create a new profile" here: https://support.mozilla.com/en-US/kb/Managing-profiles. I hope this helps!
