firefox plugin directory

TO: penguins who has trouble finding plugin directory for firefox. (Espcially java plugin follogin instruction)

SOLUTION: you can use /home/<user>/.mozilla/plugin/ as plugin directory.

So far I have no trouble.

Happy Penguins!

interesting--I just went thru this (found plugins in /usr/lib/firefox)

My system has no plugins folder in /home/user/.mozilla-----did you simply create one?

kaz2100 01-23-2007 05:46 PM


Yes, my previous versions had plugins as yours.

The new one (Iceweasel??) does not have that directory... for some reason.

Anyway, ~/.mozilla/plugin/ works.

Happy Penguins!

I also find system wide plugin directory.

I could not find this one the other day.

separate firefox directory
I found that /usr/lib/firefox-addons/plugins will be detected by firefox, but not by seamonkey (or, I'm guessing, other mozilla derivatives).

This was important to me as the 64-bit flash plugin was interfering with the 32-bit plugin I find I need for the latest version of seamonkey under ubuntu.

I now have the 64-bit flash in the above mentioned directory.
The 32-bit flash in ~/.mozilla/plugins

I am running ubuntu 8.04.1

I had some trouble with Flash player by Adobe.

Problem was:
Every time I restart, I needed to install flash.

After cleaning /home/<user>/.mozilla/plugins, the symptom above went away.

You might find that you have downgraded your flash player by cleaning that directory. You can see the versions of your plugins under Firefox by typing into the address bar:

You should definitely be running a version 10.x flash plugin.

I use the per-user libraries to prevent Seamonkey from attempting to run the 64-bit flash plugin. It works for me, but if you are likely to leave old versions in the directory and forget about it, you are probably best off clearing the directory and living with the support that comes in the standard packages which install into the /usr/... tree.

The /home/<user>/.mozilla/plugins directory is a per-user source of libraries which should override the system libraries. Unless you are doing something special, you are probably not going to want to use that directory. On the other hand, if you recall doing a bunch of work on your browser setup, clearing that directory might give you new opportunities for adventure.

Your mozilla plugins path is defined by the variable MOZ_PLUGIN_PATH.


Run env without arguments to get the values of several variables for your system.

On Ubuntu 12.04.2 LTS \n \l (Linux ws18004138 3.2.0-40-generic #64-Ubuntu SMP Mon Mar 25 21:22:10 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux) that I am runningseems that he plugin directory is /usr/lib/firefox-addons/plugins/

To make adobe flash plugin work for me I copy from the extractd plugin "" ---->/usr/lib/firefox-addons/plugins/ and /plugin/usr/* ---> /usr/

Good luck ;)

Please include some kind of a statement indicating that you're re-opening an old thread. Otherwise you're likely to confuse people and have them attempt to respond to a long-dead discussion. Thanks.

There isn't one default plug-ins directory for firefox/mozilla, but a list of locations that it will check. See here:

Although the page is slightly out-of-date now I think it should still be generally accurate.

It's interesting to learn about the MOZ_PLUGIN_PATH variable too. I'd never heard of it. Perhaps it's relatively new? But it's not the kind of thing that's likely to be preset on most systems, although you could use it to define a custom location if you wanted.
