Jorge, I'm having issues with the blocklist under Ubuntu. I've created bug#1331489 to keep the two issues separate as this is specific to the staging/release of the block.

Can you or someone else familiar with the blocklist take a look and see what's going on? It works fine under Win/macOS, but not under Ubuntu.

Thanks, I commented on bug 1331489. I'll move forward with the blocks as they are, since there's a chance the Linux block will work on other distros. However, we definitely need to look into that bug and resolve it soon.

Blocks are now live:

Flash Player Plugin on Linux 23.0.0.207 to 24.0.0.186 (click-to-play)
https://addons.mozilla.org/en-US/firefox/blocked/p1495

Flash Player Plugin 23.0.0.207 to 24.0.0.186 (click-to-play) 
https://addons.mozilla.org/en-US/firefox/blocked/p1494

Adding bug 1331489 as a dependency, since the Linux block is probably ineffective because of it.

Hi,

Currently blocking Flash Player plugin is safe but is breaking the browser on Windows 10.

How to reproduce the issue:
Click Tools \ Add-Ons \ Plugins \
->
See the shockwave flash plugin is outdated and has an Update Now link. 
->
Click Update Now
->
Click "Blocked Add-ons".Plugin check page
->
Click "Check Your Plugins".Update Now
->
Click "https://get.adobe.com/flashplayer/".Install now
->
Download the file (Version 24.0.0.194)
->
Run the file
->
Get message that you are using an old version of the installer and click finish to get the latest.
->
Click Finish, which deletes the downloaded file and opens Edge, saying that there is no need to download Flash which is included in Edge.
->
You're mad.

I would suggest to do something about this.

Hi, RESOLVED/FIXED,

This morning I managed to fix the issue, so here is the trick in case someone else goes into the issue:
...
->
Click "Check Your Plugins".Update Now
->
Click "https://get.adobe.com/flashplayer/".Need Flash Player For A Different Computer ?
->
Select "Windows 10/Windows 8" and "FP 24 for Firefox - NPAPI"
->
Uncheck Optional Offers, and click Download Now
->
Download the file (Version 24.0.0.194)
->
Run the file
->
This time no message that you are using an old version of the installer.

Conclusion: the installer that you obtain by manually requesting "Windows 10/Windows 8" + "FP 24 for Firefox - NPAPI" is not the same as the one you obtain when you let Adobe website choose for you even if it says "Your system: Windows 64-bit , English , Firefox". Note that both installers will have the same size and properties but different behavior. Another achievement from Adobe.
