It works when it does but the site list kept disappearing.

It does a decent job of blocking distracting sites for a specified time range, but once the interval is over, I can access the sites themselves, but any links I try to open within the sites are still blocked (for example, I can access Facebook, but can't click any pages in my feed). How can I fix this without disabling the add-on altogether?

Quite good, but I'm affraid there's a bug :
In "white list mode" [not so easy to find out because list still appears as "block sites" ;-) ] the protection is not active any more when one opens a new (private) window !
Hope you'll find a patch soon :-p Thanks you for this tool anyway.

good

Works fine, but only if ONE firefox window is open. It works on only one window when multiple firefox windows are open.

Too easy to unblock sites.

Keep the unblocking process time consuming.

it does not work in new window (Ctrl + N)

Incognito's not working!!!

can not block this site https://anime9.stream/

Schedule doesn`t work, so functional isn`t complete.

Versatile and performs as stated. Some annoyances such auto-filling in the URL with http:// when manually adding URLs. And some domains are treated as invalid URLs so cannot be blocked e.g. market.space.

Was noch Wünschenswert wäre:
- Die Möglichkeit geblockte Seiten in bestimmte Kategorien einzuordnen. (z.B.: Werbung; Privat; Sonstiges)
Diese übergeordneten Ordner könnten dann individuell angepasst werden, wodurch es wesentlich benutzerfreundlicher werden würde.

Was man beheben sollte:
- Wenn Firefox ein weiteres mal geöffnet wird, so kann man auf diesem zweiten Fenster alle blockierten Seiten öffnen

What else would be desirable:
- The ability to place blocked pages in certain categories. (eg: advertising, private, other)
These parent folders could then be customized to make it much more user-friendly.

What to fix:
- If Firefox is opened again, you can open all blocked pages on this second window

The add-on need to be fixed: If i open another firefox window, i can go on any website i want.

It doesn't work in Private Browsing mode

it is useful. But the global active days and times don't work for me. I have to manually enable or disable the addon.

It doesn´t work with the pop-up site: "https://www.tipico.de/de/s/landing/affiliate/bonus/?affiliateId=198220"

Why?

It does not work in private navegation :(
