Firefox pdf.js not working with clippers
Hello!
I'm using firefox dev edition, both Mendeley and Evernote addons have stopped working with PDF files.
I have reset the key "disable_full_page_plugin_for_types" in about:config (using right click > reset), because the value was "application/pdf" (now is blank) but I see no improvements.
When using the web version of the pdf.js both clippers work as expected https://mozilla.github.io/pdf.js/web/viewer.html
What am I doing wrong?

Firefox 60+ treats the built-in viewer as part of the browser ("chrome") and blocks extensions from injecting content scripts into the viewer. As you noted, the online demo is not affected because it is a pure web app.
You can use the web app to load local PDF files as a workaround (see https://support.mozilla.org/questions/1221277), but for PDFs on the web, I haven't thought of a fix.

Hi! Thanks for the pretty quick reply!!
Mendeley support (where I was before investigating the issue) told me they've installed FF Dev Edition and the addon and it worked as expected, I thought it was just me because of that, so why doesn't this affect them?
Also, so what exactly the disable_full_page_plugin_for_types "application/pdf" key means?
And if I understand your post correctly, this is a 'feature' of 'chrome' and you guys are working on how to make it work again?
Thank you!

Hi amacs, Mozilla browsers distinguish between the "content" and the "chrome"; another company liked this so much they named a bunch of products after it. But I digress.

Good question. I don't use Developer Edition so I don't know whether there is a workaround in DE. Or possibly they didn't try the exact feature that isn't working for you?

This is obsolete now. It refers to plugins like the Adobe Acrobat plugin which could embed into a tab. Flash is the only plugin that could still do that and it doesn't handle PDFs.

lol, I feel you.

Donno, I even made a video for them, their reply was that they couldn't replicate it.

Well, fml.
Good luck on sorting this out and thanks for the answers, you're awesome on this!
