Unnecessary alert when opening a link in a new tab

Posted

Sometimes when I open a link in a new tab firefox opens it properly but alerts me with "Firefox doesn't know how to open this address, because the protocol (bar) isn't associated with any program."

I just reinstalled my firefox so the problem is not with cookies or cashe. Though it might be some of my add-ons. Here's the list of what i use: https://addons.mozilla.org/en-US/firefox/collections/icegoblin/favorites/ I tried turning all of my add-ons off and it's not alerting me yet. But i'll have to wait some time as before that this alert poped up randomly. Nope :( that didn't help. Even with all my add-ons off firefox still alerts me!

There's non of those 2 lines in about:config. I deleted that file as instructed but the problem is still present ( I noticed that it usually appears when flash plugin or some script is involved.

It's not a pop-up window. It's a dialog window. If it appears it opens a blank tab after the last one with "bar:tabs" in the address line and gives me the alert. Then when i click "Ok" it loads the tab as it should be loading (not always as the last tab).

Just yesterday I completely reinstalled my windows and even before that i had that alert problem too. But i had a bunch of other problems (that's the reason to reinstall windows). So do you think it is necessary to create a new profile? Wasn't it created when i installed firefox earlier today?

By following the instructions in my previous reply, you will be able to create a New Firefox Profile. It's to test if the problem is related to your current profile.

Creating new profile didn't help either ( Now I know for sure where to test it. It always alerts me when I use youtube links.

as you recommended before i tried to run firefox in safe mode with no plugins turned on. And even though all my plugins and add-ons were off it still alerted me. most recently on pages with scripts (f.e. google reader). But that could be just a coincidence as it doesn't always appear even after clicking the same link. i just noticed that it always appears with youtube.

Do a malware check with some malware scanning programs on the Windows computer.
You need to scan with all programs because each program detects different malware.
Make sure that you update each program to get the latest version of their databases before doing a scan.

You can also do a check for a rootkit infection with TDSSKiller.
