I wants
to create an extension where content script will send message
to background page and then on browser action means clicking on extension icon will access that background page and get some data.I am using chrome Version 23.0.1271.64 m on windows8.
I am getting following error.
Port error: Could not establish connection. Receiving
end does not exist.
I tried
to solve the same. but people are using sendRequest which is not supported by chrome20+. i also found solution mentioned for chrome 20+. But not working. Please help.
Below is the file contents.
