User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; rv:1.7.3) Gecko/20041001 Firefox/0.10.1 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; rv:1.7.3) Gecko/20041001 Firefox/0.10.1 In Firefox, I clicked a link to a PDF page on my computer. Acrobat reader loaded the page in the same browser window, which was not my intent. I clicked the back button, but acrobat reader posted its "updates available" window just after I did so. Firefox and the acrobat update window hung, and stayed hung until I killed the acrord32.exe process. I clicked the PDF link again and this time allowed Acrobat to update itself. I'm now showing version 6.00.0000.0878 of nppdf32.dll (plug-in for netscape) dated 5/15/2003 12:01am and version 6.00.0001.1091 of EWH32.api dated 11/3/2003 2:23pm. I'm surprised that I wasn't already at acrobat versions from 2003. In any case, I can't reproduce the problem with the updated versions. Reproducible: Didn't try Steps to Reproduce: 1. install an out-dated version of acrobat reader plug-in 2. bring up a pdf page in the browser 3. give acro reader a chance to check for updates to itself, then click back button Actual Results: firefox hung, hogged 99% CPU, and stopped updating its window. Could not kill firefox by closing window or from task bar. After considerable delay at each step, was able to bring up Task Manager, attempt to kill firefox application (unsuccessful), then kill the acrord32.exe process (successful). Firefox returned to normal after acrord32.exe process killed Expected Results: A possible defect in acrobat reader's update mechanism should not affect firefox. At the very least, firefox should allow plug-in to hang while firefox continues to function.

[from bug reporter] forgot to mention that my current (updated) version of Acrobat reader plug-in is 6.00.0002.0126 dated 5/18/2004 2:08am.

Hi, This has been repeatedly happening. I use Windows XP and Adobe Acrobat Reader version 6.0 0 5/19/2003. After opening a PDF file through FireFox, whenever I attempt to close the tab or click on the back button the browser hangs, after which it takes a lot of time to close(i.e 15-20 mins) or I need to kill the acrobat process. I have been repeatedly facing the same problem. Regards, Ajay

Similar problem - previously using Acrobat Reader 6.0 without problems. Upgraded to Acrobat 6.0 professional, now each time I navigate to a pdf page and then try to leave that page Firefox hangs

I also get the same problem . I am using Windows 2000 5.00.2195 service pack 4. It also crashes when I open the pdf in a new tab and try to close the tab I don't think it is a memory problem the IE 6 on my machine does not behave that way and I have 1,047,544 KB of RAM. Using Adobe Acrobat 6.0 Standard. thanks kweku
