LXer: Mozilla Disables Flash in Firefox


Published at LXer:

As the zero days in Adobe Flash continue to pile up, Mozilla has taken the unusual step of disabling by default all versions of Flash in Firefox. The move is a temporary one as Adobe prepares to patch two vulnerabilities in Flash that were discovered as a result of the HackingTeam document dump last week. Both vulnerabilities are use-after-free bugs that can be used to gain remote code execution.

I noticed just a few minutes ago that Firefox is indeed blocking flash on my machine. Maybe it's time to install gnash.

I also read on the Adobe website that they aren't interested in supporting the linux platform anymore. I wonder what that's all about. Moneymaking attempt, I suppose...

Actually flash has become a real pain for secure websites and secure embedding. html5 can handle everything and use your native plugins to handle the video format.
Flash player is used pepperflash I mean google chome browser is developed in Linux. this is the websites saying hey time to close these holes flash or go away.

It is so easy to embed some nasty stuff with flashplayer.

Is there a way to fix it?

Does anyone know is html5 been implemented yet?

Not sure what the other alternatives are to Flash but I'll look up gnash.
Thanks, briandc for mentioning it.

BTW, HTML5 doesn't work with Sea Monkey.

Flash is disabled by default, but you can re-enable it with just a click on the obligatory "I know what I'm doing" button.

In my experience, Gnash is utterly broken and unusable. Lightspark is a bit better, but still mostly unusable.
There are no valid alternatives, and I think the real problem is not (just) the Adobe plugin, but flash itself.

If there is a way to re-enable it in Sea Monkey I haven't found it yet.

How do mozilla even disable flash, without a software update to firefox?

Don't get me wrong, I think flash disabled-per-default is a good thing. I'm just curious how mozilla does it, when the installed firefox version came with flash "enabled-per-default" when it was installed (version 39.0, 38.1.0, 31.8.0 are the current versions according to release and esr site.)

On Windows I just updated to the newer Flash player that became available since then.

On Linux I don't have Flash for Firefox installed, so I can't say.

I'm using gnash now, just fine. (It should be in your repos.) Both on desktop and laptop. No problems at all. Did you remove the adobe-flash or flashplugin-installer file? There might be conflicts if you have either of these installed when using gnash.

For me, gnash is the ticket!

To answer my own question: I think they are doing it via their blocklist. Which I have disabled in my firefox profile (extensions.blocklist.enabled). Flash is disabled anyway.

The problem with Gnash IMO is that it only supports flash up to circa 2010-ish. It has full flash v7 support, only partial v8 support, and nothing for v9, 10, or 11.

As long as one is ok with that, it's fine.
