I blamed on Facebook last release when it started to interrupt comments and edits, either attempting to reload the page, or simply hitting "back" one or 2 pages, even when I am thinking and do not touch the keyboard. Then I discovered the same feature while edited a post in X. Different sites, the same behavior. So, I removed all Firefox related controls from the touch bar, and the problem disappeared. I am not sure, was it the result of upgrade to MacOS 14.3, or upgrade of Firefox to 122, or is something wrong with Macbook Pro hardware?
