Stills cleans cookies, for me, after I updated to version 2.4.1 with am using a MacBook Pro with MacOS 10.10.3. HOWEVER, 1) after it cleans cookies it sometimes crashes (see below); 2) when it opens it warns me ("Attention: Your copy of Cookie Stumbler is out-of-date. Version 2.4 is available for download via the 'Check for Updates ...' menu.". ), but its Check for Updates and About windows both show that I already have version 2.4.1 (even after I quit and reopen it several times), 3) after getting "Sources" and cleaning them, I can immediately repeat this cycle (while still in Cookie Stumbler) and find more cookies (I did this four times in immediate succession).
Crash reports were obtained and submitted to the Developer for the following cases:
The first crash report happened after I ran Cookie Stumbler, cleaned out the 44 cookies it identified, then immediately ran it a second time without quitting it after running it. It then crashed while executing it's “Sources” search (i.e., before it found the cookies). After it crashed, I immediately re-opened it and ran it again - this time it found, and removed, 195 cookies. I am puzzled as to how it could find 195 cookies it wanted to remove only a few minutes after I ran it and it found only 44 cookies to remove. After it successfully ran the second time, it crashed again. I reopened it, ran it again, and it found (and I removed) an additional 163 cookies. A third crash report, from the day before (cause unknown), was also submitted to the developer.
