Hello, I use a few sites that store some settings in cookies. Some sites set short expiration dates on those cookies, others change values when I use special link (e.g. redirects me to local site when I want to use global site etc.). I need a way to lock (make read only) cookie value (and edit cookie expiration date - but that's easy). I know better what I want and don't want the site to change my settings especially as this requires many unnecessary actions to revert. I want to set it once and forget about it. Prior to FX Quantum I used Cookies Manager+ extension for that and of course this was not ported to WebExtensions standard... So my question is how to accomplish this in Quantum. I don't need an extension - any possibility is acceptable as long as I don't have to write a signed extension. I can change cookie expiration date directly updating specific record in cookies.sqlite/moz_cookies table but see no way to lock cookie value so the page can not modify it but still could read it. Any help would be much appreciated. Regards, A.
