Hi Wesley,

I tried to upload with the question earlier, but it's stuck at "Uploading".

I post it somewhere instead: http://i66.tinypic.com/np3p69.png

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac=Options) key, and then starting Firefox. A small dialog should appear. Click Start In Safe Mode (not Refresh).

Is the problem still there?

Sorry about that. It appears that we may be experiencing some minor issues with screenshots on this website.

Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.

You will need to restart Firefox for this to take effect so save all work first (e.g., mail you are composing, online documents you're editing, etc.).

Then perform these steps:

1. Click the menu button and select Options on Windows or Preferences on Mac or Linux.
2. Select the Advanced panel and then the General tab.
3. Uncheck Use hardware acceleration when available.
4. Restart Firefox and see if the problems persist.

Did this fix your problems? Please report back to us!

If the problem is resolved, you should check for updates for your graphics driver by following the steps mentioned in these Knowledge base articles:

• Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems

• Upgrade your graphics drivers to use hardware acceleration and WebGL

Thank you.

Tried that too. No avail.

Wesley, I managed to upload the screenshot now.

I checked https://sicscdm.com/redcap_demo/ but nothing wrong with the page.

Start your Computer in safe mode with networking. Then start Firefox. Try Safe websites. Is the problem still there?

Fred,

There is no white bar at the bottom in the computer Safe Mode. After I restarted normally, the problem seems to resolve by itself - no more white bar.

Hard to say what happen, but could be Safe Mode overwrote a bad file.

I am glad to hear that your problem has been resolved. If you haven't already, please select the answer that solves the problem. This will help other users with similar problems find the solution more easily.

Thank you for contacting Mozilla Support.

I'm not 100% sure, but this looks like it was one of the Firefox messages (ex. the refresh Firefox reminder, etc.) that didn't load properly. It's possible that going into Safe Mode cleared the message from the normal mode. Regardless, glad to hear that things are all sorted now. Thanks for contacting Mozilla support.

Interestingly, Firefox messages (those we get when it was freshly installed) at the bottom was covered by the white bar.
