Hello is what I found for the instructions if this is still even available on firefox.. I cannot find a subject column or a date column or where to enable starred although I can enable stars all stars or all unstard but it doesn't limit it to just a range.. help please...Skip Chosen solution Right-click any column button, such as Subject, Date etc. and enable the Starred column. Then click the Starred column button to sort the list into starred and unstarred blocks. Select the first unstarred message, hold Shift and select the last unstarred message, press Delete.Jan 13, 2020
