< Feedback on AO3: Kudosed and seen history
The script uses localStorage to remember the seen list. One possibility is that your browser clears site data automatically. Maybe this will be some help: https://support.mozilla.org/en-US/kb/storage
I really like this script, but it doesn't remember the "seen" history after I log out. I've checked that AO3 can cookies, but suspect I'm missing some other obvious setting. I'm in Firefox with Greasemonkey. Any suggestions?
Thanks for making this!
