Every time I open Firefox, it thinks that there's been a problem, and asks if I want to restore my last session.

I've seen a coupld of suggested solutions that invovle deleting files, and reconfiguring settings, but these all seem to be aimed at PC users; I'm on a Mac, and the instructions given don't work.

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.

  • Every time I open Firefox a program that has somehow attached itself to the browser opens and interferes with my searches.

    There is a program that has attached itself to my Firefox browser. Every time I open Firefox to search the internet this program is using pop-ups, to the extent that it completely interferes with my searches.

    hello Bill851, if you notice signs of malware on your system please try these steps:
    # [[Reset Firefox – easily fix most problems|reset firefox]] (this will keep your bookmarks and passwords)
    # afterwards go to firefox > addons > extensions and in case there are still extensions listed there, disable them.
    # finally run a full scan of your system with different security tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] and [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner] to make sure that adware isn't present in other places of your system as well.

    Hi timc,
    Thank you for answering my question. After taking the screen shot I started thinking "maybe it's one of the add-ons that I downloaded!!!" So I turned off the "Yahoo! Notifier" add-on, and sure enough "poof-it never appeared again"... Thanks for being the guy to get me out of myself and start thinking backwards...(And I really don't need that add-on anyway, just seemed cool that's all)... Thanks again timc...!!!

  • I updated to 3.6.15 and every time I open Firefox the Thank You for upgrading window pops up along with my normal homepage. How do I get rid of that?

  • How do I block a popup window that I have allowed to open on Firefox once? I now have the popup blocker set to block all sites, but the popup still opens every time I open Firefox or open (sometimes) a new tab.

    How do I block a popup? I allowed this popup to open once. Now I have set the popup blocker to block all sites but this popup still opens every time I open Firefox and sometimes (usually) when I open a new tab.
    I Have stopped and restarted Firefox multiple times.
    I have rebooted the computer.
    I have set the tools/options/content/block pop-up windows/exceptions to block all sites (no exceptions).
    I have no other issues with Firefox.
    I have Adblock plus (with (1) subscription) installed
    I am currently using Firefox version 4.0 on Windows7 Ultimate.

    Just to address the last point: check your History menu to see whether you have the Restore Previous Session option and use that if you can. If that is grayed out or doesn't restore everything, check the Recently Closed Windows and Recently Closed Tabs lists for other pages.
    The unwanted window may be generated by an add-on. Try disabling ALL nonessential or unrecognized extensions on the Add-ons page. Either:
    * Ctrl+Shift+a
    * "3-bar" menu button (or Tools menu) > Add-ons
    In the left column, click Extensions. Then, if in doubt, disable.
    Usually a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step.
    Any improvement?
    Here are some other things to check:
    (1) user.js file that changes Firefox startup behavior and overrides your preferences. This article describes how to track that down and delete it if you have one: [[How to fix preferences that won't save]].
    (2) Possible hijacked shortcut. Check the "target" of the desktop icon you use to start Firefox to see whether it lists the unwanted page. To do that:
    right-click the icon > Properties > Shortcut tab
    For 64-bit Windows 7, the Target should be no more and no less than this:
    "C:\Program Files (x86)\Mozilla Firefox\firefox.exe"
    (3) Possible undisclosed bundle items. If you have installed any free software recently, check your Windows Control Panel, Uninstall a program for surprises. If you click the "Installed on" column head to group by date, it is easier to spot bundled junk. Remove everything suspicious or unrecognized.
    (4) Supplemental clean up scans. Our support article lists tools other Firefox users have found helpful: [[Troubleshoot Firefox issues caused by malware]].
    Hopefully that cures it.

  • I just installed Firefox 4 from Firefox 3.6.15. Every time I open the browser, it reverts back to 3.6.15 and I have to reload 4 all over again. What gives?

    I installed beta 4 last night. Now, every time I open Firefox it asks me if I want to make Firefox my default browser. I click yes, and it goes to Firefox 3.6.15 and thanks me for upgrading. I have been running 3.6.15 since it was released. I have to reload beta 4 to get back to it again.

    I got this all screwed up too.
    hmm.. where to start?
    3.6 and 4.0 beta - really aren't intended to play well together.
    As has been mentioned above, they tend to write over each other.
    I managed to get both 3.6.15 and 4.0 beta 12 on the same machine.
    But, I had to do it several times.
    I got lucky by deleting everything Mozilla, then installing 4.0b12, then 3.6.15 - while making sure that each installed into a separate folder.
    I also took care to copy out a couple of BookMark BackUp files - just in case.
    My old 3.6# had become so bloated - and, Unstable - for Me, it was time.
    The bookmarks were all that I was still interested in.
    All the Plugins, Themes, AddOns, etc... had slowed the app to a crawl.
    So, I did as complete a wipe of Mozilla bloat code that I could, including profiles.
    I then did some registry cleaning.
    Then I installed 4.0b12 and 3.6.15.
    I can't open them both at the same time.
    If I open 3.6.15 first, then open 4.0b12 - the beta comes up as 3.6.15.
    If I open 4.0b12 first, then open 3.6.15 - the 3.6 comes up as the beta.
    This has a lot to do with both apps sharing the same default profile.
    I hope to drop down to one app in the near future.
    So, cobbling multiple profiles in order to diddle side by side apps - isn't worth it at this stage.
    For me, I can't open FF 4.0b12 when my virus protection is running. PCTools doesn't like some thing about the way FF4.0 wants to phone home when it opens.
    So, I can't commit to the 4.0b12, yet.
    3.6.15 was crashing on open too - until I uninstalled the feedback addon. - go figure -.
    Also, I can't get the 4.0b12 to start in safe-mode with the PCTools antivirus running.
    At the rater they are going, I don't see 3.6.# going away any time soon.

  • I updated Firefox. Now, I can't get rid of the blue box saying drag drag the icon to the applications folder. Plus another icon to 'eject' firefox opens. Every time I open firefox, they show up. Even Apple Help could not fix it.

    I can close the little blue 'drag' box every time I open Firefox, but that is a hassle, and I know it should not be necessary. When I try to eject the 'peripheral' icon, it says I cannot because Firefox is in use. I have to wait until I close Firefox to be able to eject it off the desktop.

    Hi dgbakker-

  • How do I stop the Welcome to Firefox tab from opening every time I open Firefox?

    I have read two ways to try and stop this in the help but they either did not apply or I could not do what they suggest.
    Every time I open Firefox of late the Welcome to fire fox tab opens along with my home page. It is only a small annoyance to turn it off each time but I would like to stop it from happening. What can I do?
    I found another where they say to delete something out of the about.config but I was not able to delete the line. I could not find how to delete a line out of the about config.

    You can check the home page setting:
    *Tools > Options > General > Startup: Home page
    Firefox supports multiple home pages separated by '|' (pipe) symbols.
    *https://support.mozilla.org/kb/How+to+set+the+home+page
    There is software like Advanced SystemCare with its Surfing Protection feature that can protect files in the Firefox profile folder against changes.
    If you have such software then check the settings or uninstall this software.

  • How do I stop the Plugin Status screen from coming up every time I open Firefox?

    I get a screen asking me to update or delete a list of plug ins. I don't want to see this every time I open Firefox.

    Updating your Plugin programs would get rid of that "nag" page when you open Firefox.
    Both Java and Flash received updates this past week.
    Type '''about:config''' in the URL bar and hit Enter. <br />
    ''If you see the warning, you can confirm that you want to access that page.''
    Pref = '''plugins.update.notifyUser''' if it shows as True, double-click that pref to toggle it to '''False'''

  • Every time I open Firefox or a new Firefox window, my home page opens but so does a second tab showing the LinkedIn login page. Don't know how this started happening or how to stop it.

    Figured it out. There was code in the Preferences/home page field telling it to open my home page and that page at the same time in two tabs. Don't know how it happened, but is fixed now.

    Yeah, I don't know why I can't find my posted problem of November 18, but it was similar, and I also figured out how to fix it. IF when you open Firefox to your homepage and MORE opens than IS your homepage, then go to tools, options, and check your homepage info. You will find the URLs to your homepage plus whatever windows are opening that you do NOT want. Delete everything but the homepage and close. I had at least 10 windows opening from a browsing session over a week ago every time I opened Firefox... aggravating!

  • How do I stop Firefox automatically opening and forcing me onto a second tab with a Google sign-in every time I open Firefox?

    Every time I open Firefox to search for something - it automatically opens a second tab and forces me to that tab. On the second tab is the Google account login. I now avoid using Firefox if I can because I cannot shut this off.

    Does this also happen in Safe Mode? You can restart in Firefox Safe Mode from the Help menu:
    * Click the menu button [[Image:New Fx Menu]], click Help [[Image:Help-29]] and select ''Restart with Add-ons Disabled''.
    To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.
    Also, on the General tab in Firefox preferences, what are "When Firefox starts" and "Home Page" set to?

  • In windows 7, firefox 4.0.1, How do you close tabs so they don't open every time I open firefox?

    Can't close tabs so they don't open every time I open Firefox.

    It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
    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: Open Containing Folder
    *http://kb.mozillazine.org/Profile_folder_-_Firefox
    Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).
