Did you want those 5 websites to load at startup?

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Thanx a lot!

It's working great again.

Is the browser now working properly in normal mode?

You can check if you have a user.js file in the Firefox profile folder that sets the browser.sessionstore.resume_session_once pref to true.

• http://kb.mozillazine.org/browser.sessionstore.resume_session_once

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.

Hello FredMcD,

trying to solve this problem, it seems to be working.

But I started my computer severly days later and the browser was not working properly in normal mode.

Only when I start firefox the first time it's not okay, but the second or third or more times later at the same day (when my computer is on) it's all okay. When I shut my computer down and start it again, the problem is coming back.

What can I do else?

Thx for your help.
