I have been using Firefox (and it's previous iterations) as my only web browser for well over 20 years and have never run into any major issues with web site support. Recently, my local utility (PG&E) made an "update" to their site and now explicitly do not support Firefox (blank web pages and a message saying they only support Chrome and Edge on Windows). Are there any other Firefox users out there and have you found had issues with any other web site?
