Anybody else notice that when using the back arrow on some sites, it just won't stop back-arrowing? I mean, usually, when you have reached the very first site opened in the current tab, the back-arrow will grey-out and become non-functional. But some sites are allowed to embed an instruction which causes Firefox to just keep on back-arrowing indefinitely, without EVER greying-out the back-arrow; it just keeps on re-loading the same initial web page. The yelp.com website is a good example of this behavior. Firefox should prevent sites from embedding functional-override coding which causes the browser to behave abnormally like this. Another functional-override example are websites that, DESPITE having a global Firefox browser setting to NOT auto-fill fields, the site causes Firefox TO REMEMBER the data anyway, and then to re-display the data at the credentials step as a pull-down menu underneath the Username field and, more often, the 2FA field. Haven't seen any site yet override the no-auto-fill setting for the Password field, however...luckily.
