I hope this request hasn't been posted a billion times before now...
I'd love to see an option in Adblock Plus to TEMPORARILY whitelist a site, preferably for the current session only.
There is currently an option to whitelist a site, but it seems to be permanent - a month from now, that site will still be whitelisted unless I manually clear it from the whitelist. This seems incredibly dangerous to me. I may need to allow a particular site this one time only, but I don't want the whitelisting to persist once I close the browser tab/window. I don't see any current option to do this. Ideally, it would be a simple option in the existing menu.
Thanks for considering this.
