From 1 site only, when I download a pdf file, I get an error message that the file is a jsp file (not a pdf) & Adobe can't open it. How can I fix this?

I found this problem with 2 different browsers but had success with a 3d. I noticed that the file on Firefox was downloading with Zoom Downloader. Could this be the problem? (Don't know where Zoom Downloader came from.) I am using Firefox 18 and Win 7.

Try to delete the mimeTypes.rdf file in the Firefox Profile Folder to reset all file actions.


Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe mode start window or otherwise make changes.
