Facebook does not work on my iMac but it works fine on my iPad and MacBook Air & office PC computer. It comes up and shows one item on my wall but I can't click on messages, etc. Any ideas?

Thanks!

Hello,

Try clearing cache and cookies first. If that doesn't work, try Firefox Safe Mode.


Clearing cache and cookies

Many site issues can be caused by corrupt cookies or cache. In order to try to fix these problems, the first step is to clear both cookies and the cache. Note: This will temporarily log you out of all sites you're logged in to. To clear cache and cookies do the following:

  1. (Firefox 57 and above) Click the Library button 57 library icon and choose History.
    (Click the menu button New Fx Menu and choose History in older Firefox versions.)
  2. In the History menu, choose "Clear Recent History...".
  3. Under "Time range to clear", select "Everything".
  4. Now, click the arrow next to Details to toggle the Details list active.
  5. From the details list, check Cache and Cookies and uncheck everything else.
  6. Now click the "Clear Now" button.

Further information can be found in the Delete browsing, search and download history on Firefox article.


Firefox Safe Mode

Try Firefox Safe Mode to see if the problem goes away. Firefox Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).

If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:

  • Click the menu button Fx57Menu, click Help Fx57Help and select Restart with Add-ons Disabled.

If Firefox is not running, you can start Firefox in Safe Mode as follows:

  • On Windows: Hold the Shift key when you open the Firefox desktop or Start menu shortcut.
  • On Mac: Hold the option key while starting Firefox.
  • On Linux: Quit Firefox, go to your Terminal and run firefox -safe-mode
    (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)

When the Firefox Safe Mode window appears, select "Start in Safe Mode".

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to find the cause.

To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.

When you figure out what's causing your issues, please let us know. It might help others with the same problem.
