Adobe Reader question — I have the latest version of Adobe Reader installed, but it's not working as it should with Waterfox. It will not open a file in Waterfox. Instead, either I can chose (in Tools>Options>Applications>Portable Documents Format) to use Waterfox's native PDF reader, to use Adobe Reader (Default), to download the file, or to ask every time. Selecting to use Adobe Reader does not open the file in Waterfox. Instead it opens the PDF file in a separate Adobe Reader window. I no longer have the option to "Use Adobe Reader in Waterfox".
The "fix" for this problem in Firefox was to delete the file mimeTypes.rdf in my Profile folder and let Firerfox regenerate that file when it next restarts. The option to open a PDF file in Firefox using Adobe Reader should then be available in the pull down menu.
That "Fix" didn't work in Waterfox. The mimeTypes.rdf was regenerated, but the option didn't become available.
My thinking is that Adobe Reader is a 32-bit program and Waterfox is a 64-bit program, so Adobe cannot open a file in Watrerfox. Is anyone else having this problem with Adobe Reader? I tried searching for posts about it in this forum, but had no luck.
