If I want to open a link from anything external, text editor, desktop shortcut, applications, etc., while Firefox is running, I have to close Firefox and then click on the link, which will then open Firefox. This is an ongoing and intermittent problem that can't always be duplicated and seems to occur most often after Firefox has updated, but I am asking for a resolution or workaround now because there hasn't been a recent update and Firefox is once again ignoring outside links when running, and only opening them if I have completely closed Firefox. This is annoying and unnecessary and of course if I change default browser to Chrome or IE, external links will open in those browsers with no problem while those browsers are running.
