The mail client I use is Gmail, your browser (Firefox) is very good but has problems when Gmail attachments, mark an error and I should try again (I do unsuccessfully). Should definitely resolve this. Thank you.

Isisombululo esikhethiwe

The solution was:

Try to set the Boolean pref network.http.spdy.enabled to false on the about:config page.

Thanks for trying. Greetings.

Can you try to start Firefox in Safe Mode to see if Firefox works properly with no error? You can start Firefox in Safe Mode below:

  • Windows/Mac: Go to Help > Restart with add-ons disabled
  • Linux: Run firefox -safe-mode in the Terminal/Konsole

If Firefox opens up fine with no problems, it's probably one of your extensions that's causing the issue. You can re-enable your add-ons one by one until you find the one that causes the issue upon being re-enabled.
