I was thinking if its possible to just install an extension for Google Chrome and open .pdf files with that extension, but not the .pdf files that I can click on while browsing the Internet, but the ones that are already on my desktop, or lets say, the ones that someone transfer from USB to my computer, can I open those in the Chrome or is it not possible? The reason why Im asking this is because Adobe Acrobat has an intrusive update window that I regularly shut down in the Processes, but it turns on its own again and its really annoying.
