A gray bar with code in it is appearing at the bottom of the firefox screen.
Since yesterday (2/25/14) a gray bar that displays some code is appearing at the bottom of the screen. I tried rebooting my laptop, but it doesn't go away. It takes up about an inch of space on the screen, just above the Windows bar.

Yes. That is likely a problem with a broken extension as posted above.
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.
If it works in Safe Mode and in normal mode with all extensions (Firefox/Tools > Add-ons > Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit)

hello, can you try to replicate this behaviour when you launch firefox in safe mode once? if not, maybe an addon is interfering here...

Please provide a screenshot of that grey bar and that code.

It is best to use a compressed image type like PNG or JPG to save the screenshot and make sure that you do not exceed a maximum file size of 1 MB.
Then use the Browse .... button below the Post a Reply text box to upload the screenshot.
Here is the screenshot of the problem.
Looks like a fault with Adblock Plus. See the Adblock Plus forum.

I followed the safe mode instructions above. No one add-on seemed to trigger the strange bar. However, systematically disabling all the add-ons and testing them one-by-one, and then restarting them one at a time seems to have cleared the problem. I don't know why. I seem to be running both Adblock Plus and Trueblock ... would that be a problem?
Thanks for the help.
I've seen a report that Trueblock can cause this issue.
