hello,

read that deleting "gxineplugin.so" does the trick...

- loc gxineplugin.so <--'
/usr/lib/mozilla/plugins/gxineplugin.so

how to disable gxine without deleting this file??

- grep -r gxineplugin.so ~/.mozilla <--'
~/.mozilla/firefox/pluginreg.dat - "/usr/lib/gxine/gxineplugin.so:$"

i erased lines linked with gxine and made file read-only (r--------)
when i reload firefox gxine is still in "aboutlugins" page
and
~/.mozilla/firefox/pluginreg.dat
is modified

The easiest thing to do is to simply go to Edit > Preferences > Content > Manage File Types and change the default action for the mime types you don't want the plugin to handle.

There used to be a control to deactivate plugins from the preferences panel, but it looks like they've removed that. Perhaps there's an extension out there somewhere that adds that functionality back into the browser?

I don't know if making the plugin read-only is enough to disable it. For all I know, reading may be all that's required for it to work. Also, the Firefox plugin finder can look in several places for plugins, so even if you delete one, it may still be finding it in others. To find out exactly which plugin your browser is using, open up about:config, find the line "plugin.expose_full_path" and change it to true. Now about:plugins should show the full path to the plugins being used.

there is no Edit > Preferences > Content > Manage File Types menu
in firefox 1.5.0.7

have to find another way
thank you

Then you'll find it under the downloads tab or somesuch. I don't remember now exactly where it was in 1.5, but I know it's there somewhere. Just search around the preferences.

there is
Edit > Downloads > View & Edit Actions
inside i see 1 action about vector graphics

In Firefox, go to Add-ons and disable the start gxine plugin.
