I want to do this for Internet Explorer (v 11.0; 64-bit?) and SeaMonkey (v 2.49.5; 32-bit), which are the main two browsers I'm using.
The Knowledgebase article didn't help me.
I have PDF-XChange Editor (v 7.0; 32-bit) available on my system, and the "File Associations" category does not appear when I open the PDF-XChange Editor, and enter "Preferences".
It is worth mentioning that I set up PDF-XChange Editor as a 'portable' installation, in the sense that it was unzipped and saved to a relevant directory, rather than using an "installer".
I have already successfully 'manually' configured my OS (Windows v 8.1; 64-bit) to use PDF-XChange Editor as the default application to open PDF files from the system — in particular, from the File Explorer.
Internet Explorer
The Knowledgebase article says that I should be able to enter the "Manage Add-ons" dialogue box and then click "Toolbars and Extensions" and select Show = "All add-ons" to find the relevant PDF-XChange Editor browser plugin(s). However, none are listed for me.
Could this be because of my "portable" installation? If so, is there a way to manually force the relevant plugins to be listed, so that I can then choose them from Internet Explorer's "Toolbars and Extensions" interface?
(Maybe just copying a file or two to some location, or maybe doing something like running commandline codes?)
SeaMonkey
I understand that SeaMonkey is not one of Tracker Software's target browsers (even though it is built on Gecko). I am also broadly aware of the NPAPI 'doomsday' issue that affects many browsers, (including Firefox) — but does not affect SeaMonkey.
Currently under Preferences > Browser > Helper Applications I have several items listed under "Content Type" that relate to PDF files, of which the most relevant is probably "pdf File (application/pdf)", for which the Action is set to "Always ask" — and the same choice for all of the other varieties of PDF content.
The available options for the Action on the aforementioned "Content Type" are:
- "Always ask"
- "Save File"
- "Use PDF-XChange Editor (default)"
- "Use Adobe Acrobat 7.0"
- "Use Adobe Acrobat (in SeaMonkey)"
- "Use other..."
When I set the Action to "Use PDF-XChange Editor (default)", the PDF opens up, but not in the browser — it opens in an external instance of PDF-XChange Editor.
When I reverted to "Always ask", then I (for the first time ever) got a dialogue box asking how I would like to view the PDF file. However, the options there are only for viewing outside the browser, not inside the browser.
By selecting "Use Adobe Acrobat (in SeaMonkey)" I can recreate the original behaviour.
In SeaMonkey if I look under Tools > Add-ons Manager and click on "Plugins" I can find "Adobe Acrobat 19.21.20047.26424" "Adobe PDF Plug-In For Firefox and Netscape 19.21.20047" "Last Updated 12 October 2019".
But there is no listed plugin for PDF-XChange Editor.
A quick search for downloadable PDF-viewing plugins for SeaMonkey on the official website revealed only one (a fork of PDF.js).
Thanks for any advice.
