What does this mean ? TypeError: rows[i] is undefined
This error message keeps popping up. Not sure why it started, but I think it was after a recent update to firefox or one of my plugins. Very very annoying

This issue can be caused by an extension or plugin that isn't working properly.
Start Firefox in Use Troubleshoot Mode in Firefox to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
- Don't make any changes on the Safe mode start window.
See
- Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems
- Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
- Use "Disable all add-ons" on the Safe mode start window to disable all extensions.
- Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
