This worked for me.
(I) Navigate to “C:\Program Files\Adobe\Acrobat 10.0\Acrobat\Browser\WCFirefoxExtn\components”
and create a new temp folder. Move the following files from the components folder to your new “Temp” Folder.
1. WCFirefox4Extn.dll (For newer Firefox browsers)
2. WCFirefox3Extn.dll (For older Firefox browsers)
3. IWeb2PDFComponent.xpt
(II) C:\Program Files\Mozilla Firefox\plugins and create temp folder there
Put the following in the new temp folder along with any other Languages that are there.
nppdf32.dll
nppdf32.DEU
nppdf32.FRA
(III) Open RegEdit and Search for “web2pdfextension@web2pdf.adobedotcom”
1. Select or “highlight” the “web2pdfextension@web2pdf.adobedotcom” entry.
2. Click on File and select “export” and export (backup) the “web2” entry to a safe storage folder on your computer.
3. Right click the “web2” entry and select delete!
(IV) Start Firefox and see “Create PDF” no More!
