Applescript to get frontmost tab’s url and title of various browsers.

get_title_and_url.applescript

# Keep in mind that when asking for a `return` after another, only the first one will be output.
# This example is meant as a simple starting point, to show how to get the information in the simplest available way.

# Google Chrome
tell application "Google Chrome" to return URL of active tab of front window
tell application "Google Chrome" to return title of active tab of front window
# Google Chrome Canary
tell application "Google Chrome Canary" to return URL of active tab of front window
tell application "Google Chrome Canary" to return title of active tab of front window
# Chromium
tell application "Chromium" to return URL of active tab of front window
tell application "Chromium" to return title of active tab of front window
# Safari
tell application "Safari" to return URL of front document
tell application "Safari" to return name of front document
# Webkit
tell application "Webkit" to return URL of front document
tell application "Webkit" to return name of front document

get_title_and_url_from_front_browser.applescript

# This example will return both the URL and title for the frontmost tab of the active browser, separated by a newline.
# Keep in mind that by using `using terms from`, we’re basically requiring that referenced browser to be available on the system
# (i.e., to use this on "Google Chrome Canary" or "Chromium", "Google Chrome" needs to be installed).
# This is required to be able to use a variable in `tell application`. If it is undesirable, the accompanying example should be used instead.

tell application "System Events" to set frontApp to name of first process whose frontmost is true

if (frontApp = "Safari") or (frontApp = "Webkit") then
  using terms from application "Safari"
    tell application frontApp to set currentTabUrl to URL of front document
    tell application frontApp to set currentTabTitle to name of front document
  end using terms from
else if (frontApp = "Google Chrome") or (frontApp = "Google Chrome Canary") or (frontApp = "Chromium") then
  using terms from application "Google Chrome"
    tell application frontApp to set currentTabUrl to URL of active tab of front window
    tell application frontApp to set currentTabTitle to title of active tab of front window
  end using terms from
else
  return "You need a supported browser as your frontmost app"
end if

return currentTabUrl & "\n" & currentTabTitle

is it possible to store window object using objc or in applescript in userdefaults?

For chrome - in windows : echo PlaceholderChromeURL, in mac : osascript -e 'tell application "Google Chrome" to return URL of active tab of front window', For Firefox - echo PlaceholderFirefoxURL & osascript -e 'tell application "Firefox" to activate' -e 'tell application "System Events" to keystroke "l" using command down' -e 'tell application "System Events" to keystroke "c" using command down' -e 'delay 0.5' -e 'the clipboard'
