User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322) Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040803 Firefox/0.9.3 When I access an Adobe Acrobat document via the web using FireFox with Adobe Reader 6.0, and I exit the FireFox by clicking the 'Close' button in the upper right hand corner, all open instances of FireFox stop responding. I do see an Adobe Reader message box appear which states 'One or more PDF documents are open inside a web browser. If you exit Adobe Reader now, those documents will be closed. Are you sure you want to exit?" However, this message box is unresponsive and appears on the Desktop behind the open instances of FireFox. This error only seems to occur if there are more than one FireFox window open concurrently. All instances of FireFox must be terminated using Windows Task Manager after this error occurs. Reproducible: Sometimes Steps to Reproduce: 1.Open FireFox. 2.Create several tabs, and navigate to different websites in each. 3.Go to the following website:http://www.businessobjects.com/support/support_programs.asp 4. Select the "Support Programs Legal Terms and Conditions" link on the right hand side to open document at the following URL: http://support.businessobjects.com/crystalcare/downloads/elite_standard_tandc.pd f 5. This document should open in a new FireFox browser window. 6. Close the new FireFox window. Actual Results: An Adobe Reader message box appear which states 'One or more PDF documents are open inside a web browser. If you exit Adobe Reader now, those documents will be closed. Are you sure you want to exit?" However, this message box is unresponsive and appears on the Desktop behind the open instances of FireFox. All instances of FireFox browsers open are unresponsive and must be terminated using Windows Task Manager after this error occurs. Expected Results: The application should close cleanly. This bug does not seem to occur if you navigate directly to the PDF document. This issue also seems not to appear if the 'Hide the tab bar when only one website is open' is active.

(In reply to comment #0) Have noticed that 0.9.1 closes PDF documents as long as after you have clicked on the X to close the window you DO NOT click *anywhere* until the "One or more PDF documents are open inside a web browser. If you exit Adobe Reader now, those documents will be closed. Are you sure you want to exit?" message appears. Once that message has appeared and you have clicked on Exit, you are fine. If you should click elsewhere before the message appears, the browser will hang and must be shut down through the Task Manager. Part of the problem may be the time that it takes for the message to appear - users believe that they must have missed and not clicked on the X, go to click on it again, and the browser then hangs.

I encountered the exact same situation each time I close an instance containing a pdf document. Same irresponsive message.
