Tap Row For Details Message Disappears Rated 3 out of 5 stars
Whilst the concept is great, unfortunately this add-on does not work on a Samsung Galaxy S2 (Android)
After the initial installation the TAP ROW FOR DETAILS appears and if you hit it the sub page displays in the preferences correctly.
However after closing Firefox and re-opening it the message no longer shows.
I uninstalled the add-on, reinstalled it, and the same thing happened.
NB This may be Firefox problem rather than with the add-on because the same thing happens with the Clear History add-on.
