Hi all.
Since the whole site update, I've been having problems with one of my Firefox plugins (MPIV).
When you hover an image, it's supposed to fetch the high quality version and show it as a floating popup. Now instead it displays the thumbnail.
Tried to work it out myself, but I have no clue how this thing even worked in the first place, but maybe someone here can or has already solved it.

Here is a link to the github page to download the script. It needs tampermonkey or the like to work.
Here is a link to the page that explains (I guess) how custom rules are made.

This is the rule I had and which worked before e621's update:
{"r":"e621\\.net/post/show/","q":"div.content a[href*='/data/']"}

I'm using Firefox 52.0 64-bit

I know, I know, I should update the browser, but none of the extensions I use are supported in the newer versions, and I have already tried upgrading and finding new replacements, but I always fall back to my old setup.

Anyhow, any help is appreciated!

You should consider using Imagus. It's much better and more customizable than MPIV.

.. Does Imagus work on a version of firefox as old as 52?

I assumed not. If it does, then I'll just point out my settings are on the last page of the Tag Project thread, and they still work fine.

I've used Imagus for many Firefox versions. According to the add-on's version history page, the latest version of Imagus can run on Firefox versions as early as 48.

Wow, works like a charm. Many, many thanks!
