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!
