Unable to view .gifv files in Imgur in Firefox

[John Corliss]

For some time now, about a year or so, whenever I go to an Imgur page
which is supposed to display a .gifv (basically an .mp4 video), I get a
small loading icon placeholder which then disappears. That's all. The
..gifv file never displays and I don't even get a placeholder other than
the temporary loading one.

I've Googled and Binged the issue to death, but can find nothing. I'm
running FF 50.0 on XP MCE SP3. Here are the plugins I'm running and
their status:

OpenH264 Video Codec provided by Cisco Systems, Inc. 1.6 (Always Activate)
Shockwave Flash 23.0.0.207 (disabled)

The difficulty goes back several versions of FF. Anybody have an idea
what the problem is?

TIA

What application do you have set to open .gifv files under Options -
Applications? That could be where the problem lies.

Works for me in Firefox 50.0 and previous versions.
For example, http://i.imgur.com/N6BDEzW.gifv


Imgur used ".gifv" for animated .gif files, not .mp4 video.
The standard extension for these files is .gif (except at Imgur up
until a couple of months ago).
Firefox does not use a plugin to display animated .gif files.


Do you have an adblocker or something else which could be blocking animated .gif files?

Have you tried SOP for troubleshooting?

No such listing. However, I didn't change anything from when they would
load and play. It just quit working after one of the FF updates.

That's not a .gifv, it's a .gif. Right click on it and the context menu
has no video controls, just say stuff about an image.

Not so. Gifv are .mp4 files:

I've disabled the AdBlockplus extension at the Imgur website.

All but nos. 5 & 6. I won't reinstall or refresh such a complex program
to correct such a problem. I was just hoping that somebody else has had
the problem and knew a quick solution.

That example indeed is an animated gif.
So I tried their demo gifv: http://i.imgur.com/zvATqgs.gifv
Context menu shows video controls, but image stays frozen in
my FF 49. Works like a charm in PaleMoon 26 (PM 27 is broken).

Here's a picture of what I see when I click on that link in Firefox:

Windows 10 Home build 14393.447
Video working fine in Palemoon 27.0.0 (64bits), Firefox 51.0b2 (64bits),
IE 11 and Chrome 55 Beta (64bits). No sound in any of them if there's
supposed to be sound?

[WaltS48]

It didn't work in #7, "Create a new Firefox profile"?

[OT]
When I said "PM 27 is broken" I meant it barfs when I
start it on my Win7 pc, with an errormessage apparently
related to something with language.

Nope. I have two profiles, my default one with about:config mods,
extensions and plugins, and my testing profile with no about:config
mods, no extensions and only the plugins which come with Firefox.

In both profiles:

Maybe it is your WindowsXP that can't handle .gifv?

Both links in the other posts work just fine in Firefox 50 on my Windows
10 notebook and Ubuntu 16.04 Linux desktop computers.

[John Corliss]

No, it used to handle them just fine. As I mentioned in the OP, .gifv
files at Imgur quit working several versions of FF back.

I do know that FF uses system codecs to display .mp4 files, but I have
the K-Lite Codec Pack installed.

The problem is that Firefox not only won't display .gifv files like it
used to, but it won't even provide a placeholder for them!
