Window properties are not available any more if you use : tell application "Firefox" to activate. And thus until next restart of Firefox Reproducible: Always Steps to Reproduce: 1.tell application "Firefox" to return ( name of front window) 2.tell application "Firefox" to return («class curl» of front window) 3.tell application "Firefox" to activate Actual Results: if you run step 1, it will work fine, then step 2 will return an error. if you restart Firefox and run step 2 first, it will return the url. if you try step 1 after after step 2, step 1 will return an error. If you run step 3, step 1 will work fine again but not step 2 .... Expected Results: A reliable support of AppleScript in Firefox. AppleScript is very usefull to Mac developers, this is the only reason while Safari is yet more popular to Mac users than Firefox.
This bug report isn't very clear, so I can't test most of it. But there is one part I can reliably reproduce: 1) Start Firefox 3.0.4. 2) Start Apple's Script Editor (/Applications/AppleScript/Script Editor). 3) Paste the following into top part of the Script Editor window, then click on the Run button: tell application "Firefox" to return (name of front window) Each time you do this, a different string of apparently random text will appear in the bottom part of the Script Editor's window. With Firefox 126.96.36.199 you get the correct results (the string in the front window's titlebar). With today's Minefield nightly you always get an empty string. I tested on OS X 10.5.5.
