Can't open links from external applications - windows 10

Clicking links in external apps ends with message: "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window.".

I do not want to start new firefox instance, I want to open links in new tabs. How can I make it work that way?

Can you explain what you mean by "clicking links in external apps'"' and what are these apps ?

Presumably if for instanced you click on a html document on your desktop, or a link within a WordProcessor document it does opens ok in the running Firefox.

Check the target field in the Firefox desktop shortcut and make sure you do not start Firefox with the -no-remote switch or have set the environment variable MOZ_NO_REMOTE=1 (Control Panel > System > Advanced > Environment variables).

By external programs I meant eg. Thunderbird.

It turns out I had environment MOZ_NO_REMOTE set to 1 (wonder how it got there), but changing it back (and restarting computer) did not help.

The shortcut to firefox has target "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" so I am guessing I do not have "-no-remote" enabled.

Do you have an idea what else might be causing the problem?

Did you remove the MOZ_NO_REMOTE environment variable and confirmed that it didn't return after a reboot?

This variable shouldn't be there as it will cause issues like you experienced.

Previously I had changed MOZ_NO_REMOTE value from 1 to 0. It did not help. But removing it completely fixed the issue. Thank you for your help!

You're welcome.

It is about the mere presence of the variable and Firefox doesn't check the value.
