Sounds that Tab Mix Plus is broken. You can check the Tab Mix Plus forum:


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

Are you able to open the Add-ons page (Command+Shift+a)? If so, could you try disabling your Conduit-related plugin(s) by setting it(them) to "Never Activate". This probably won't affect the current window, but could take effect in a new window or after you quit and start Firefox up again.

Also, I don't know whether this is related, but your version of Tab Mix Plus is from October 2013. There was an update in September 2014 which is available from the Add-ons site: https://addons.mozilla.org/firefox/addon/tab-mix-plus/
