Firefox thinks I'm using and older Flash version

Question

I'm running Firefox 35.0 on Fedora 20. It has the current latest Adobe Flash version (11.2.202.440).

Firefox is blocking Flash and displaying an alert bar, claiming it is outdated:

In English: Firefox has prevented an outdated plugin 'adobe flash' from running

Just to be sure, I ran:

• yum reinstall http://linuxdownload.adobe.com/adobe-release/adobe-release-x86_64-1.0-1.noarch.rpm -- it installed adobe-release-x86_64.noarch 0:1.0-1.
• yum reinstall flash-plugin -- it installed flash-plugin.x86_64 0:11.2.202.440-release.

Then I restarted Firefox in safe mode and checked about:plugins.

Shockwave Flash

    File: libflashplayer.so
    Path: /usr/lib64/flash-plugin/libflashplayer.so
    Version: 11.2.202.425
    State: Enabled (STATE_VULNERABLE_UPDATE_AVAILABLE)
    Shockwave Flash 11.2 r202

Checking the actual .so file for versions strings, it looks like I have the correct version.

$ strings /usr/lib64/flash-plugin/libflashplayer.so | | grep "11.2.202"
FlashPlayer_11_2_202_440_FlashPlayer
LNX 11,2,202,440
11.2.202.440
drm/%s/%s/%s/11.2.202.440%s

What's going on and how can I fix it?

Answer 1

There is a pluginreg.dat file on my Firefox profile folder:

Generated File. Do not edit.

[HEADER]
Version:0.17:$
Arch:x86_64-gcc3:$

[PLUGINS]
libflashplayer.so:$
/usr/lib64/flash-plugin/libflashplayer.so:$
11.2.202.425:$

(...)

Removing it forces Firefox to re-generate it with correct data.

Now about:plugins states:

Shockwave Flash

    Arquivo: libflashplayer.so
    Caminho: /usr/lib64/flash-plugin/libflashplayer.so
    Versão: 11.2.202.440
    Status: Ativo
    Shockwave Flash 11.2 r202

If you want, you can disable the blocklist using about:config:

extensions.blocklist.enabled false

or using prefs.js:

user_pref('extensions.blocklist.enabled', false);

• blocklist.xml
• prefs.js
