Steps to reproduce (tested on ipad mini 2): 1. Register a simple content blocker with one rule (hiding "share" buttons on macrumors.com) [{trigger: {url-filter: ".*", resource-type: ["document"], if-domain: ["*macrumors.com"]}, action: {type: "css-display-none", selector: ".social"}}] 2. Open macrumors.com. Share buttons are hidden http://screencast.com/t/88mfI2UM 3. Tap on the article header and select "Open in New Tab" 4. Wait a bit then switch to that new tab Expected result: Share buttons should be hidden Real result: Share buttons block is visible The block will be hidden if you refresh the page
The issue is still there. Here's an easier way to reproduce: 1. Register a simple content blocker with one rule (hiding "share" buttons on macrumors.com) [{trigger: {url-filter: ".*", if-domain: ["*iana.org"]}, action: {type: "css-display-none", selector: "body"}}] 2. Open example.org 3. Cmd+Click on the "More information..." link 4. Wait a bit then switch to the IANA tab Expected result: The page content is hidden Actual result: Nothing is hidden, you need to refresh the page for the rules to be applied
Strange that opening in a background tab would have an effect.
Huh, it seems that this issue is invalid after all. Most likely I've not waited enough for a content blocker to be compiled and applied.
