A quick tip for anyone who’s having problems with openhab with the maximum number of HTTP connections in their browser (symptom: browser stops responding and needs to be restarted) and can’t or doesn’t want to use a reverse proxy:
You can easily increase the number of connections in Firefox. To do this, enter about:config in the address bar, search for network.http.max-persistent-connections-per-server, and increase it (I use 12 without problems).
On mobile devices the about:config options are only available in “Firefox nightly for developers” (e.g. play store).
