Chrome has a built-in PDF printer (unless I've done something wrong).

It's damned useful to have a pdf reader and pdf printer in the browser.

Ok. I see where you said PDFium is Chrome PDF Viewer. Thanks. I thought that PDFium was an internal part of Chromium and not a plug in at all.

I was under the impression that even if a plugin is disabled, it still used resources, was involved in the loading process, etc, and it was better not to have any extra plugins, and to use extensions where ever possible.

So when comparing "PDFium" the PPAPI plugin versus the pdf.js extension, where would the significant points of comparison be in regards to speed, resource usage and compatibility be?

Yes I am aware of the depreciation of NPAPI-plugins.

As I said in my email I am trying to:

1. not just disable plugins from Opera, but specifically how/where to DELETE them

2. determine if "Chrome PDF Viewer" in the form of pdf.dll is in fact PDFium

Ok. I know about opera://plugins/. I should have mentioned that.

What I am trying to do is:

delete the unwanted plugins from my computer or from where ever opera is finding the plugins:

because I am trying to determine if PDFium is in fact working.

For example, I have a plugin called "Chrome PDF Viewer" with a Location: C:\Program Files (x86)\Opera Developer\25.0.1606.0\pdf.dll.

Is this the old Chrome PDF viewer, or is the the internal PDFium viewer ?

Other browser's have built-in print to PDF.

Now that Opera has PDFium, why can't Opera ?

How to tell without a doubt that PDFium is working under Opera Developer v25?

How to enable ?

How to delete all other browser PDF plugins to make sure that just PDFium is being used ?

(Where are all the plugins being stored ? )

Oops.. Opera Portable is not 1.0 (it's the old 12.16)

Ok. So I'll load Opera 1.0 onto my test bed machine.

Thanks

Thanks!!! I have IMAP and it's an internal Gigabit Connection. I'm going to play around with the opera portable app version. I'll just try the index.ini and accounts.ini. files to start.

index.ini - listed everything in the sidebar panel
filter with learning - separate file under autofilter folder called filter_###.ini

accounts.ini - email accounts
email accounts may also be called incoming#.txt or outgoing#.txt

operaprefs.ini - opera preferences

Then I'll move on to the

Paths
Preferences
%AppData%\Roaming\Opera Mail\Opera Mail\operaprefs.ini
Saved session
%AppData%\Roaming\Opera Mail\Opera Mail\sessions\autopera.win
Opera directory
%AppData%\Roaming\Opera Mail\Opera Mail
Mail directory
%AppData%\Local\Opera Mail\Opera Mail\mail

Ok, so where is the Opera Mail directory ? It's not under Program Files or Program Files (x86) or ProgramData ?

So I'm looking inside the index.ini for the names of my filters, and the index.ini file in a mail folder ?

If I have a learning filter it will have a separate file in the autofilter folder?

ok, so if I use the following, it should put both my cache and session.db* onto the ramdisk F: ?

"C:\Program Files (x86)\Opera\launcher.exe" --user-data-dir=F:\opera --disk-cache-dir=F:\opera

Then what about plugins and extensions ? Are they loaded into memory once at startup or each time they are needed ?
