Try to disable hardware acceleration in Firefox (you need to close and restart Firefox).

• Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
• https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes

Start Firefox in Safe Mode to check if one of the other 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:

Thanks for the fast reply. I did all you suggested but nothing corrected the problem.

I decided to tackle this a little more rather than wasting your time. I wasn't able to find the answer to solve the problem, but this is what I did.

I went to Firefox's site for all the past versions. and started installing them (what a job). I wanted to see if I could help by determining at what version showed the change. This is how things ended up. ' Version 21.0 dated May 14/13 worked fine all around. Also, NO problem with anything on all earlier versions/dates.

Version 22.0 dated June 24/13 was the version my problem first shows up. All newer versions after that have the problem also.

I don't know if anyone else has had this problem but I hope it helps.

As for working on this, it is really a very minor problem. It's just an annoyance and I can live with it. However, I have decided to install v21.0 and that's fine by me.

Thanks a million for your help. It is really appreciated. ' Regards, ve6tp
