Firefox crashes when I close it and when I attempt certain pages, also gives an error message when I open it, but starts up if I close the message.
[Exception... "Could not convert JavaScript argument arg 0 [nsISupports.QueryInterface]" nsresult: "0x80570009 (NS_ERROR_XPC_BAD_CONVERT_JS)" location: "JS frame :: chrome://skype_ff_extension/content/browserOverlay.js :: <TOP_LEVEL> :: line 8" data: no] Message appears when I try to open FFox. If I close this message, FFox opens and works mostly OK. If I request certain pages, the error message appears again. I can close it and view the page but after that FFox crashes. FFox is reporting thecrashes to Mozilla.

That is a problem with the Skype extension (Tools > Add-ons > Extensions).
Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the add-ons is causing the 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 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")
