I've just upgraded Firefox to 47. No matter which site I go to, the
Storage tab in dev tools always says "No data present for selected host". Can anyone else replicate?
Go to this JSFiddle, click
set item then
get item. If the string "value" gets printed beneath the buttons, it means the item was successfully saved, then retrieved from sessionStorage. Now open the Storage Inspector in dev tools, select
sessionStorage on the left, and see whether you can see the contents of storage. I cannot even though there are contents there.
Update June 17 2016
Turns out the
Storage Inspector within Firefox dev tools is broken if you select
Firefox settings >> Privacy >> History to
Never remember history or
Always use private browsing mode (Firefox 47 32bit on Windows 7 64bit)
A fix appears to be in the works. I just installed Firefox 48 beta 1, and I no longer experience the problem.
