Uploading Fractal Image Plugins into a browser

[rspek]

I have downloaded from XnView the 2 plugins needed to open fractal images (xfif.dll and deco_32dll). XnView opens up fractal images (as does Photoshop). However, I receive an error message when I attempt to upload these plugins into Chrome, Firefox, or Safari. Is there a way to get one or more of these browsers to permit me to upload these fif plugins? Will the browser then permit me to view fractal images?

I think xfif.dll plug-in is meant solely for XnView.
I have googled that name of browser plug-in for FIF used in times of Netscape was NPFIF.dll.
I assume this thread from 2008 which mentions user with the same name as yours here and the same problem was a solution given to you back then.
Modern browsers switch from NPAPI plug-in architecture to Pepper API (PPAPI) architecture.
So to make older plug-ins work they have to be rewritten or support for older type plug-ins has to be enabled in browser. If you still have NPFIF.dll, you may try.
Though no guarantee ten years old plug-in will work after enabling NPAPI support.
Few links about how to enable NPAPI support in modern browsers (if they still have one).

How to manually install .dll plugin in Chrome I don't know if it works, I'm not using Chrome, but seems like it's using Firefox settings.

How to manually install NPAPI plug-in in Safari for Windows Answer from 5 years ago, but is the same as manually installing .dll plug-in in Chrome.

If you don't have NPFIF.dll but want to have one, googling for "fvp11w32.exe ftp" yields many FTPs where you can download installer for this browser plug-in. One of them ftp://ftp.uni-potsdam.de/pub/systems/wi ... e-plugins/. But if you want only NPFIF.DLL and DECO_32.dll files without changes in registry made by installer, use Universal Extractor. You have to use it twice - first to extract all files including one called DATA.Z from fvp11w32.exe (you can do it with WinRar too), second to extract everything including required .dll's from DATA.Z file (it is compressed with InstallShield and therefore is needed Universal Extractor).

For XnView and NConvert.
