I am using Firefox (March 2026 version) and BT internet email wit Win11. Since January 2026 update I have problems entering email addresses that are present in my Contacts list. When starting the cursor goes to the CC: line before switching to the To: line. Then when I start entering an emaiil address that is in my contacts list an option(s) show and when clicking on the correct one instead of it displaying in full in the To: line it shows the first few characters in a red in a box with an x at the end. I then have to delete this and fully type in the full email address. This is very annoying and time consuming. I had hoped the recent update would have fixed it, but it has not. Could you kindly investigate - many thanks
