In the past the caret in text entry fields used to blink/pulsate/flash forever in both Firefox and Thunderbird. (Text entry boxes, such as the browser URL-bar, the e-mail To/Subject/Content textboxes, online forms, etc.). Now in the latest versions of Mozilla Firefox 110.0.1 and Thunderbird 102.8.0 the caret stops blinking after just a few seconds. This is very confusing and frustrating for my grandmother and she already called me several times because Firefox and Thunderbird 'stopped working'. I explained to her that this is a new feature but she does not understand and keeps forgetting it after a few days. She is used to the cared blinking continuously, it has been blinking for the past decades whenever she wanted to type something in the computer and it only stopped blinking when the computer program froze or crashed. I am sure that my grandma is not the only person having issues with the caret not flashing, I for one also would like to have a caret that blinks forever, so when I look away from the screen and look back I do not have to search the text to find where I left my caret. Please make it so that the default caret appearance and behavior is the same as in all other programs (i.e. blinking forever), as it used to be in the past, just like what everyone is used to. I argue that the majority of users is used to and also expects a blinking caret when they are writing an e-mail or search online and you are confusing a whole lot of people with this minor change, people who do not know how to report bugs or seek help themselves. It's a sign of poor user-friendliness if grandmas need to call their grandchildren or children for help just to write e-mails which they used to be able to do on their own for many years in the past. I hereby suggest adding an accessibility option for people who wish to disable the blinking cursor and to change the default behavior back to 'caret flashing forever'.
