Hello,

Try Firefox Safe Mode to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.

(If you're not using it, switch to the Default theme.)

• You can open Firefox 4.0+ in Safe Mode by holding the Shift key when you open the Firefox desktop or Start menu shortcut.
• Or open the Help menu and click on the Restart with Add-ons Disabled... menu item while Firefox is running.

Once you get the pop-up, just select "'Start in Safe Mode"

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article for that.

To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.

When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.

Thank you.

Thanks but i already tried safe mode and creating a fresh new user profile without any addons. The problem still percist.

Make sure that Firefox is set correctly as the default browser.

Already done that. Should have mentioned that in my first post.

Are you using the -no-remote command line switch to start Firefox?

You can also check for problems with DDE.

Nope. It seems to a bug. It won't work opening links in withSiX either unless Firefox isn't running. Clicking on a link while Firefox is running won't work.

As said before

If I click the link it starts a new Firefox process, it opens the link/s as it should, (clicking the links the next few times, opens new tabs as usual). But if i close Firefox again and restarting it for a new process and then click on links in the Skype chat window "after" i started a new Firefox session, it doesn't respond, it just flash the program window borders.

I see there is no answer and I have the same problem - links from skype and from windows live mail won't open.

It worked for couple of weeks with no problem and suddenly today links just make skype flash exactly as in christianhbergs description and in windows live mail they are becoming purple but firefox doesn't react.

as soon as I make IE as my default - links are working, but not with firefox.

So I assume the problem is in firefox (not in skype or WLM nor in Win8)

(running Win8 and FF25.0)

There's more - FF doesn't want to open html files that are saved to pc, even thou I just saved em, but when I click on em happens nothing and when I rightclick and choose open with FF happens nothing.
