This is my first post so I'd like to say hello! This is kinda error report for https://www.brewersfriend.com/mash-chemistry-and-brewing-water-calculator/ that does not seem to work for decimal values when I use Firefox browser. Everytime I enter the decimal value (say 7.9 for pH) the text box is marked red and there is a red border around it. Chrome works ok. Regards /t.
