I cannot attach files to my Yahoo mail with Firefox 21. It works fine with IE.

Up till about 3 weeks ago I had no problems. Now when I try to attach any file to my Yahoo mail I get a red triangle saying 1 file cannot be sent. If I go to Explorer it goes right through. I tried all the stuff about deleting the history and cache and everything else but it still doesn't work.

Which security software (firewall, anti-virus) do you have?

Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test to see if that helps.


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 or otherwise make changes.
