Stupid Firefox 7!  It doesn’t recognise my plug-ins!  But they did work in FF3.5.  What gives?!!!

Ok, perhaps I’m overreacting.  In fact, I am.  Sorry.

I use #CentOS for my daily work which includes the rather antiquated Firefox v3.5.  Ouch.  As a web developer, it’s good to test on legacy browsers but it’s also important to use the latest – so I updated to the latest Firefox (v7, at time of writing).

Because my desktop machine (HP Opteron ML115) has 6GB of RAM, I typically use the x86_64 (64-bit) edition of #Firefox.  However, unlike Firefox v3.5, v7 doesn’t seem to pick up my plug-ins automatically from /usr/lib64/mozilla/plugins.

To fix this, I had to open a shell and navigate into my home directory‘s mozilla plugins directory (I didn’t even know this existed until now!).

cd ~/mozilla/plugins
Then, just fix up all the missing symlinks:

ln -s /usr/lib64/mozilla/plugins/* .

No problemo!  They’re now all back again at about:plugins  🙂
