Hello

What have you tried so far?

Can you try reinstalling Firefox? Uninstall it from your control panel > programs and features/add / remove programs (if you want to keep your bookmarks and other information, not deletion of personal information). After uninstallation, delete the Mozilla Firefox folder to remove the remnants of files damaged uninstallation (your profile is in a different location, so will not be affected by the present):

  • (installation of 32-bit) C:\Program Files\Mozilla Firefox
  • (installation of 64-bit) C:\Program Files (x 86) \Mozilla Firefox

Download and reinstall the latest version:

  • When I go to rip a cd I get message saying that windows is not able to accomplish this task.

    When I go to rip a message from windows cd is that it is not able to accomplish this task. also when I go to change where I whant recorded music it is empty and I'm not able to open to choose where to save it. Windows Media will play music, but that's all

    Hello from the McCanns,

    Thank you for the question!

    I'm sorry to know that have problems you with the ripping. As I understand it impossible to rip a disc and get a message that unable to accomplish this task.

    I need to ask you some questions to help you best.

    Method 1:- You may be able to complete the rip by turning on error correction.

    In Windows Media Player -> click Tools-> Options -> peripheral, click the CD burner, choose > Advanced and set the error correction on it.

    Method 2:- There are two ways to change the rip while settings in the Player library. You can insert a CD into your CD-ROM drive and clickRip settings, or you can click on the Rip music tab in theOptions dialog box. The music tab Rip in the Options dialog box offers additional options that are not available in the Rip settings menu.

    To extract music from a CD, follow these steps:

    a: For best results, make sure that you are connected to the Internet before you begin.

    When your computer is connected to the Internet, the Player attempts to retrieve information from press about the tracks being ripped from an online database. The player then adds the information to the files during extraction.

    Note that you can rip a CD when your computer is not connected to the Internet. However, the player will not be able to identify the name of the CD, the artist who created it, or the names of the songs until you go online.

    b: insert an audio CD into the CD drive.

    c: (Optional) If you want to select another format (for example, MP3 instead of WMA) or bit rate (for example, 192 Kbps instead of 128 Kbps) for files created during extraction, in the Player library, click the Rip settings menu and then click on Format or the quality of the Audio.

    d: (Optional) If you do not want to extract from each song, in the Player library, clear the check boxes next to the songs you don't want to extract.

    e: Click the current playback orRip CD CD Rip button in the library of the player to begin extraction.

  • When I try to open firefox, and other things appear the next tex said thatt was not able to load XPCOM

    Loïc Macarena SilviaFigueroa,

    Do a clean reinstall and delete the program folder before Firefox to (re) install a new copy of the current version of Firefox.

    Download a new copy of Firefox and save the file to the desktop.

    Uninstall your current version of Firefox, if possible, the settings in the software security and cleaning of the Windows registry.

    • Do NOT remove the data personal when you uninstall your current version of Firefox, because all profile files will be deleted and you lose personal data such as bookmarks and passwords from other versions of Firefox profiles.

    Delete the program folder Firefox before installing newly downloaded copy of the Firefox installer.

    • (32-bit Windows) "C:\Program Files\Mozilla Firefox\"
    • (Windows 64 bit) "C:\Program Files (x 86) \Mozilla.

    Your bookmarks and other personal data are stored in the Firefox profile folder and will not be affected by a uninstall and (re) install, but make sure that 'delete personal data' is NOT selected when you uninstall Firefox.

    If you keep problems also create a new profile.

    I have photoshop cc 2015. For the last 2 days it does not open when I double-click the icon. What can I do to fix this?

    OK completely reboot Windows 7. When he started to look in the Task Manager under process for photoshop.exe it shouldn't be there. If it is highlighted and press the button end process. Now right-click the Photoshop icon and select run as administrator. Photoshop starts, you should see photoshop.exe in the list of running processes. When you close Photoshop it should disappear from the list.

  • Why do I get messages saying that I have not destroyed tabs; I ususally click on the red dot. why I get this error message?

    In the past I could navigate from one site to another without closing a tab. The messages now appear that say I have does not close a tab and need to close or to restore. I tried closing of tabs as I've used them but my tab bar shows no tabs open when I close Firefox. When I restart Firefox I get messages saying that I did not close the tabs! It's very annoying. How do I put it back for when I click the red dot, it is closed. and when I restarted Firefox it just goes to my home page? I use a Mac 10.6.8

    No, there is no problem now with this parameter when the bug is fixed.
    the problem is basically firefox 20 wrong classifies this way to close the browser as an accident & will launch the restore function of session at the next launch of the browser. the key to everything: config above completely shuts down service sessionrestore for accidents.

    Once the bug should be fixed in firefox 21, I would recommend resetting browser.sessionstore.resume_from_crash back to its default value "true" If, so that you get the benefit of a restored session, where firefox crashes really some time.
