It appears to be non-functional (tmp** is not displayed), so I switched to a similar add-on.

I love this addon and have been using it for 5 years now, but recently I noticed a weird issue: when I open a few links from my bookmarks in rapid succession, the tabs get stuck and I can't switch tabs anymore or do anything else. It doesn't happen when this addon is disabled.

Seems to leave behind site data for every temp tab and site visited. Maybe Strict mode incompatibility? Whatever the case I've got dozens of listings reporting 0 Cookies but site data is still being stored.

Unfortunately this add-on blocks usage of web.de's Mail-Check add-on (https://produkte.web.de/mailcheck/#.suche.brandlink.mailcheck): when trying to login to one of the configured mail accounts only an empty tab comes up with title "Placeholder for extension post request - tmp ". Is there a way to disable this add-on for specific sites? When I disable Temp Containers all is fine. Fwiw: I use this in conjunction with Multi-account containers add-on.
Other than that seems to work fine.

I use a local homemade written html file as a start/homepage [HP]. Each time I open the browser my HP appears but it isn't in any container. Make it so everything is in a container, including locally stored content.

Brilliant use of containers, if only it wouldn't be so absolutely confusing. The settings here are overwhelming and I'm not sure what they do.

ok but supercookies in SiteSecurityServiceState.txt are not cleared!
