After reinstalling firefox clicking Plex no longer opens up Plex

When I click on the system icon Plex or click “Open Plex” nothing happens anymore. This was not a problem until Firefox was having issues and I reinstalled it and now when I click the plex media server on the trey nothing happens. I have to manually type in the plex address. I tried changing my default browser which did nothing. Previously it would take me to the plex web app. I installed the Plex web app on my Google Chrome browser but now a popup comes up saying it will be removed on October 24th. Help! This sucks.

Make a bookmark in your browser for the address http://127.0.0.1:32400/web
It is the same as clicking on the tray icon.
