Hi. I have been using Firefox with DuckDuck Go extension for maybe 6 - 7 years now. This worked well with Gmail, no issue. Since July 2025, an update came through in Firefox and now an issue with Gmail. The mail opens properly but after 5 to 20 minutes the responsiveness slows down to stop. A pop up above the mail view states that Firefox is causing the slow down and there is a button to press to stop the issue. When pressed, the mail screen is frozen and I have to exit the G mail and restart. I have uploaded the most recent version of Firefox. Firefox Ver 143.01.1 64 bit. Windows 11 Pro Cannot find the version of G mail used, but it is the latest update. I have contacted G Mail about this issue as well. How to resolve the issue, going on since sometime in July? I was hoping that a recent update by Google or Firefox would resolve, but it has not. Very annoying especially when corresponding or trying to load attachments. Please help. stickum333@gmail.com
