The Ghostery extension has been reported to cause such issues with tabs in Options/Preferences.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

• Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
• Do NOT click the Reset button on the Safe Mode start window

Hi cor-el,

Thank you for your reply. Before I had seen your reply. I went into options and under general, all of a sudden it showed what should be there. I closed browser and did it again and it didn't show. It has been blank for roughly two months. Just seems funny that I ask a question and after all this time of not showing what it should, it does, to only be blank again.

I have also been trying to update the flash player. That comes up completely blank as well with nothing showing at all. I did this several times the day before I posted my question. That same day I also hit the reset button for firefox when I was having trouble trying to update the flash player.

I did as you said to do. Nothing has changed. Is there something else that I could try?

You can find the latest Flash player versions for Firefox on this page:

The flash player is up to date now. Thank you.

I still would like to mention that the adobe download manager was blank. I never had this problem before. I gave it enough time even though it was blank before I closed it. I checked to see if the flash player was updated, and it was.

Each time that I clicked on options today, under the general tab, everything is showing as it should be.

Thank you again cor-el for your help. I do appreciate it.
