Small window box shows "TypError: oE is null" and then closes the browser.

This "seems" to happen randomly. Whenever I open up the browser, everything is working fine for awhile and then the window just pops up.

Re: Small window box shows "TypError: oE is null" and then closes the browser.

This issue can be caused by an extension that isn't working properly.

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.
