Long term issue of losing pinned tabs because I break a tab off the main firefox instance to work on it in a seperate window and then at some stage I close the firefox window that contains the pinned tabs AND AFTER I close the breakout tab and this seems to remember that no pinned tabs ever existed. This behaviour is idiotic and clearly buggy, certainly shouldn't be a feature or normal behaviour. The pinned tabs feature is advertised as placing permanently some tabs that open for sure at every launch of firefox in a known location to the left - things we use just about everyday (gmail, iCloud, reddit etc), hence their permanence and it seems to be impossible to code something that if NO firefox window is opened then when we launch Firefox we get the default view of our pinned tabs and a fresh page OR default homepage etc. Seems ridiculous to me. Whats the logic here ? I vote FOR making this a permanent feature.
