The problem seems to be associated to blocked flash content.

Seems to be isolated to each Firefox release channel. Initially broke for standard Firefox, then Nightly, then Beta and most recently Aurora/DE (for me). Broke for standard after an update, Nightly and Beta after closing and then reopening browser and broke for Aurora while watching a flash video.

Object still remains (black box for youtube, white box for content on Adobe Flash Player about page), still recognised by Adblock.

dlassuncao, I'm sorry it took so long to get back to you about this report! If you're still seeing this, I have some questions:

* Are there any crash reports in about:crashes? If so please link to the crash report URL.
* What website(s) are you visiting? In general we should only be launching that plugin-container when the site loads a new Flash element, so if you just stay on a normal single page it might crash once and just wait.

Hi Benjamin!

It's been some time since I posted this bug report. Since then Firefox, java, flash and other softwares are not the same anymore. Also I can't really remember what exactly are the sites visited, i believe it happened to all flash-enabled sites. In this scenario, it become difficult to replicate the bug, and I have no bug report dated from near 2015-01-28 (older one date from 2015-05-29). At the end, as the bug is not showing itself in this Firefox version (42.0) i think its reasonable to close this case.

Still, if you need any information,  I am at your services.

Thank you for your attention.

Thanks. We've been doing active work in plugins, as has Adobe, so I'm glad to know that this is mostly-better.
