I can confirm that using FF, going to Tools / Add-ons / Plugins / Check to see if up to date , I am indeed being advised that the Adobe Reader PDF Plug-In For Firefox and Netscape, version 11.0.11.18, is "out-of-date" --- despite this version having been installed just a week ago (12 May). So there's no need to be embarrassed... you did nothing wrong nor unsafe here.   As best as I can tell, it looks like DC is the "new" version of Reader... but I'm hoping others will be able to confirm this. ---------------------------- Looking further on the Adobe site, I don't see the old/"standard" Reader offered there anywhere... they do still offer a "MUI" (Multi-Language) version 11.0 here:   [URL] which immediately needs to be updated to 11.0.11 [URL]
Well, here I sit being both angry and embarrassed. I went into Firefox tools to check for out of date Add-Ons and saw that Adobe Reader plug-in needed to be updated. Foolishly, I just went through with the FF update and ended up with Adobe Reader DC. Does anyone else here have that version on their computer? It ended up removing my old version of Adobe Reader. I did go into the security settings and make sure it wasn't "anonymously" phoning home with my usage patterns. Would you recommend that I uninstall it and go back to plain old Adobe Reader? I really hate being so stupid after all these years of being so careful about so-called updates! Thanks for any info and/or recommendations. Mary
