I have an extension (FEBE) that, among other things, backs up and restores cookies. I backup the cookies by opening cookies.sqlite, read each record and write a JSON string to an output file. When restoring, I do just the opposite - read a JSON string from the output file and write it to cookies.sqlite. Fx would recognized the restored cookies immediately.
This all has been working fine until recently (probably when Fx 44.0 was released). Now, the cookies are successfully written to cookies.sqlite (I can open the database and see them all there) but they do not show in Fx options > Privacy > Show Cookies.
It is acting like the currently recognized cookies are in a cache somewhere. Can anyone tell me where this cache might be? Or is there a way to tell Fx to re-examine cookies.sqlite and update this cache?
