It's only the first screen/tab I open after firefox is completely shut off... it shows the borders of the screen for 5 seconds, before showing the content (empty page) and then I can start and everything after that is fine.

In safe mode it opens without delay, so my question is, what in the normal start-up could be causing this delay, I have reinstalled firefox, disabled all extensions and plugins.

Hello ellina, try disabling graphics hardware acceleration and check it again.

You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).

Then perform these steps:

  1. Open Firefox Options window (Preferences on Mac or Linux) as follows:
    • In Firefox 29.0 and above, click the menu button New Fx Menu and select Options for Windows or Preferences on Mac or Linux.
  2. In the Firefox Options (or Preferences) window, click the Advanced tab, then select General.
  3. In the settings list, you should find the Use hardware acceleration when available checkbox. Uncheck this checkbox.
  4. Now, restart Firefox and see if the problems persist.

Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:

In safe mode, also, hardware acceleration is disable, see : http://kb.mozillazine.org/Safe_mode

Thank you.
