Hello all, I would like to disallow/block images by default for all sites. I have found this can be done on [[https://support.mozilla.org/en-US/questions/1226175 this]] thread which outlines that: "You can disable images on the '''about:config''' page : Type '''about:config''' in the address bar and press Enter (accept the risk, if asked) Type in the search bar : '''permissions.default.image''' and set its value to '''2'''" This works very well and I am happy with this, however, in addition to this I would then like to be able to whitelist some websites that I want to allow images to be loaded on (i.e. wikipedia). I have found in [[https://support.mozilla.org/en-US/questions/1277711 this]] thread the 'block images domain checkbox' was discontinued in Firefox 72, but can be re-enabled with: "extensions.contentblocker.enabled = true" also in "about:config", however, I am unsure if I can use this to whitelist sites. TL;DR: I want to block all images on websites by default, but I want to be able to whitelist some that trust; how can I do this? Thank you in advance. :)
