pages keep saying I need a plugin but "search for plugin" button CONSISTENTLY yields "none found" -- do I need one or not?

Posted

I have a nearly-new Mac 10.7.5. Downloaded Firefox just fine. But many (not all) pages give me a popup saying that additional plugins are needed to display all the content. When I click the "Install missing plugins" button, I get a popup saying, "No suitable plugins were found." Does this mean the popup saying I am in need of a plugin is false, or what?

Chosen solution

Your plugins list doesn't show the Flash plugin that is used by many websites, so maybe it is about that plugin.

You can check in Tools > Add-ons > Plugins if it is possibly disabled.

Update the Flash plugin to the latest version.

I probably have the same problem. I know Flash isn't working correctly for me (those installer links don't fix it).

However, a related difficulty is that none of the dialogues tell us what is missing. Couldn't firefox display some more details so that it's possible to find out the problem ?

'A plug-in is needed to display this content' -> 'install plugin' -> 'no suitable plugins were found' -> 'find out more about plugins or manuall find missing plugins' -> 'check your plugins' tells me there are no plugins.

That doesn't really help, does it ?

It also seems to tell me java is disabled, but points to an Oracle link that doesn't correctly describe installation (it seems toi think that just untarring the distribution somewhere arbitrary will work).

You can check for problems with current Flash plugin versions and try these:

  • disable protected mode in Flash 11.3 and later
  • disable hardware acceleration in the Flash plugin

Thanks, but that information seems to be mostly windows-specific. There is some linux uninstall information that I could try, though that may then break the remaining functionality I've got in the 64-bit installation.
