Firefox thinks I'm using and older Flash version

Solution 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

Solution 2:

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
