The reason why I wanted to use Firefox instead of Chromium is the latter seems having some issues with custom-cards as NONE of those are showing at all (see picture). When I download the Firefox 52.9.0 ESR version for MacOS, I’m having the very same issue… Problem is that Raspbian is only compatible with Firefox 52.9.0 ESR… and versions over 54 aren’t compatible with Raspbian anymore due to an unresolved issue (see answer) I’ve read a little about this issue and apparently the issue has been resolved in a later version. The old Firefox 52 ESR will not get any more updates for security or stability fixes. When reading the Web Console in the Firefox Developer section, I get: Error submitting step Synta圎rror: JSON.parse: unexpected non-whitespace character after JSON data at line 1 column 5 of the JSON data Firefox 52.9.0esr released on Jwas the last and was officially made End of Life or EOL as of Sept 5th when 62.0 and 60.2.0esr were Released. I was planning to use the Lovelace UI I’m working on with the RPi3s… and When loging in… I get the following error message: I have several wallmounted RPi3 with the official touchscreen and now I’m in the process of making the whole thing work… and it turns out I haven’t expected Firefox in Raspbian not being able to connect to HA.
