This site: https://www.lawanswers.com.au/threads/ebay-and-paypal-australian-consumer-law-on-withholding-payments.6537/ Popped out a new window in the background when I highlighted some text. 1. Every time JavaScript is used to pop-up a new tab or window, an icon should be made available to report the site for unwanted pop-ups. The site could be added to a blacklist. The blacklist should be downloaded in whole rather than queried on Firefox servers for privacy (Mozilla does care about privacy doesn't it?). 2. If a site is on the blacklist and it tries to pop-up a tab/window then the popup could be blocked and same icon could highlight for say 10 seconds. Clicking the icon in this case would give the options to open the popup, white-list the page for the user, vote against the blacklist. Something like: [ ] Show the blocked page. [ ] White-list this site for me. [ ] I don't think this site should be blacklisted [ OK ] [Cancel] Some fuzzy logic could perhaps be used to determine whether or not to keep sites on the blacklist. Sites with very large amounts of blacklisting+white-listing could be manually looked at. Also: I don't ever want anything happening when I highlight text other than the text being high-lighted, it's not necessary and it completely ruins the browsing experience. No excuses, it's bad. Add a white-list if necessary for the 0.01% edge cases where this might be useful.
