AlertBox has no flexibility when customising alerts Rated 3 out of 5 stars

A lot of thought has gone into this add-on. The developer provides excellent support. Firefox popup notifications are via Firefox and are only displayed for a few seconds. Poor presentation of url’s which will be rectified in the next version I understand. Problem with framed sites. No help files. Good responsive forum from the developer. I shall have to continue with WebMon or URLy Warning because they present the data simply and clearly and enable me to set a search range within the html coding. Both programs are no longer in development but Webmon is the superior option because it is only 532kb with so many customisable options. Everything works brilliantly. URLy Warning is the next best option but loading the page in the default browser and setting page limits for 'When page' 'contains' 'does not contain' do not work at all. See the AlertBox forum for more detail on these points
