• Deduplicator bookmark does not work with Firefox 35. What should I do?

  It worked before I installed the latest version of Firefox. Now whenever I press start remove duplicates, nothing happens. Please help me understand what to do. I use Mac 10.9.5. Thank you!

Unfortunately, the developer did not provide a contact email link to encounters with bugs or comments and did not provide a "home page" with the details either.

• update 10.9.3 Mavericks and now scrolling does not work in Firefox.

  I've updated yesterday, and now the wheel on my mouse (optical mouse Belkin) does not work in Firefox. It works everywhere else, but not in Firefox.

  Can scroll you with the keyboard?

  On Mac, scroll bars may be hidden and are showing them when you scroll down the page, so you can see the current scroll position.
  The idea is that a Tablet is used that does not need to be visible and therefore more screen real estate for the navigation area, scroll bars.
  You can make scroll bars always appear:

  • System Preferences > General > display the scroll bar > choose "always."

  Note that on Mac you can turn on or off the mode full screen with command + SHIFT + F.

• eBay sidebar does not work in Firefox beta 20.0.

  The sidebar of eBay does not work with Firefox Beta 20. I can navigate its tabs, but cannot get any content or connect to eBay with it. He worked until a recent firefox update. I tried to uninstall the sidebar and reinstall but nothing has changed. I have just updated Firefox to version than 20.3 Beta but there is no improvement with the side bar of the eBay on it. Please advise on a solution I use eBay most of the time box.

  Sounds as if this add-on may need to be updated for Firefox 20; Contact the developer of this add-on.

  In the meantime, if you use "mission critical" or "must have" addons you would be better to use the final version of Firefox and stay away from the beta version.

• Norton Toolbar does not work with Firefox 17, provided Comcast Norton Security Suite, Win 7.

  I have Norton Security Suite provided by Comcast. Norton Toolbar does not work with Firefox 17.0.1 on my Win 7 machine. I lived all the questions on this topic and did all the steps and when I click on "Add-ons", he always says that the toolbar is not compatible. It works with IE, but I prefer to use Firefox.

  I had the same problem in the past. If you call customer Norton service toll-free they have always helped me start (without charges) when I have updated to a new version of Firefox - seems to happen every time even if I run the updates regularly. Hope that this phone help-Norton support is always very friendly and helpful-just Google their 800 number.

  Try Firefox SafeMode to see how it works there.
  
  A way of solving problems, which disables most of the modules.
  
  (If you use it, switch to the default theme).

  • You can open the mode without failure of Firefox 4.0 + by pressing the SHIFT key when you use the desktop Firefox or shortcut in the start menu.
  • Or use the Help menu option, click restart with the disabled... modules while Firefox is running.

  Do not choose anything at the moment, just use 'continue in safe mode.

  To exit safe mode of Firefox, simply close Firefox and wait a few seconds before using the shortcut of Firefox (without the Shift key) to open it again.

  If it's good in Firefox Safe mode, your problem is probably caused by an extension, and you need to understand that one.
