Just downloaded latest version and now Firefox won't open a new tab. How do I fix this?

I've been using Firefox for years, however as of last week I can no longer open a new tab. I have to go to "file > new window" new tab quick function nor dropdown work. I'm using a Mac OS X 10.9.3.

'''''[https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode Start Firefox in Safe Mode]''''' {web link}
While you are in safe mode;
Press the '''<Alt>''' or '''<F10>''' key to bring up the tool bar.
Followed by;
Windows; '''Tools > Options'''
Linux; '''Edit > Preferences'''
Mac; ''application name'' '''> Preferences'''
Then '''Advanced > General.'''
Look for and turn off '''Use Hardware Acceleration'''.
Poke around safe web sites and see if there is still a problem. Then restart.

    Uninstall the Ask toolbar and it should work again. There is a compatibility issue with the Ask toolbar and Firefox that prevents new tabs from being opened.
    There are a couple of places to check for the Ask toolbar:
    * Check the Windows Control panel for the Ask Toolbar - http://about.ask.com/apn/toolbar/docs/default/faq/en/ff/index.html#na4
    * Also check your list of extensions, you may be able to uninstall it from there - https://support.mozilla.com/kb/Uninstalling+add-ons

    Hello, discodiva64
    Thank you for the question.  Try uninstalling all components of iTunes in the order specified of the article below.  Once this is done attempt to install iTunes again.

    If the issue persists, I would recommend going through these steps for error 7. 
    iTunes for Windows: "Error 7" message when opening iTunes
    http://support.apple.com/kb/ts3074
    If the issue still persists, you may need to process the steps in the article below for each component when uninstalling iTunes.

  • A recent download made yahoo as my default site when opening a new tab. how do I change this?

    A recent software update/download has changed my default site (on new tab only) to http://search.yahoo.com/?fr=freeze&type=W3i_NA,132,3_6,Tab%20Search,20111042,6894,0,22,0
    I cannot remember how to change the setting as I do not want Yahoo as my default (anything). Can someone please advise on how to reset the 'new tab' from yahoo to mozilla?

    Look at this extension to set which page to open in a new tab ("A blank page", "The home page", "The current page" or a user defined URL):

  • I just reset my pass code on my ipod Touch and now it won't let me in.  How do I fix this?

    I just reset my passcode on my Ipod Touch, turned it on and it locked me out.  Is there a way to get this reset?

    Place the iPod in recovery mode and then restore the iPod via iTunes on your computer. For recovery mode:

  • I upgraded my Itunes to the latest version and now it won't let me view my library with the column browser. Can i get that back?

    i upgraded my Itunes to the latest version and now it won't let me view my library with the column browser. Can i get that back? I tried using the shortcut for it and nothing happens. When I try to do it from the view menu, it shows up as something I can't click on. The new library format is driving me crazy and I just want to get back to the old library view.

    We need to sort out some facts here first:
    •  You cannot be running Mt. Lion on your iMac G5.  What Mac is it?  What is the Model Identifier listed in About This Mac; More Info; Hardware Overview
    •  What is the model of your Epson Scanner?
    •  Have you attempted to scan using Image Capture, located in your Applications folder?
    •  Your Palm Pilot software will only run in Snow Leopard; so depending upon which Mac you have, you will either have to:
    1)  partition your hard drive or add an external hard drive and install Snow Leopard into it to "dual-boot" when you want to access you Palm software, or
    2)  install Snow Leopard Server (now available from Apple for $20 telephone orders USA & Canda only) into Parallels 8 to run your Palm software in Mt. Lion:

  • Uninstalled new version, horrible. Installed the older version and now it won't open! HELP WANT MY MUSIC!

    I installed the new version thinking it would be the same, It was horrible! uninstalled it... Installed the older version and now it won't open and when I try it says it can't because the library can't open because it was used on a newer version. Come on! I just want my music! How do I open this and get my music back.
    I put my Ipod in and it still says the same thing, what's going on? Please help me!

    I don't know whom to thank first-- b noir for telling me about the Lorraine fix or Lorraine for figuring out the fix. THE LORRAINE FIX WORKED FOR ME!!! (I feel a little like I am advertising "Hooked on Phonics" with that last line!)
    Thank you doesn't say it strongly enough, but THANK YOU b noir and Lorraine for your help. I was to the boiling point last night and starting to get there tonight. Now I am resting easy and thankful that there is a community of computer users out there who care enough to troubleshoot problems together and work together to figure out a solution--and then to take the time to post and share information.
    I would STRONGLY suggest that anyone who is having the iTunes issues where iTunes just plain won't open at all after downloading the newest version and has a pc with Norton Internet Security 2005 try the "Lorraine Method."
    I am so happy I think I might sing. Or not--I will let my songs on iTunes do the singing for me now that I can again!!!!!!!
    And to those still looking for answers--be patient--I now know how incredibly frustrating this can be and I hope that you all find your solutions very very soon!!

    AppleWorks ne peut pas fonctionner sur Mavericks, ou quelque chose de plus récent que Snow Leopard.
    AppleWorks cannot run on Mavericks, or anything later than Snow Lepoard.
    LibreOffice can open word processing documents and some Draw documents. The most recent version will open spreadsheets, with some limitations, otherwise only the older version of Numbers, not the one currently in the Mac App Store, will open them. Nothing will open database documents.
