I've tried installing Flash into my Portable Firefox. I followed this link:
https://portableapps.com/u3support/firefox_for_u3#plugins
but it did not work. I did get the yellow bar mentioned in the article but it indicated that I was being blocked from downloading. I re-set Firefox to allow downloads from both fpdownload.macromedia.com and macromedia.com (as well as portableapps.com). However whenever I click on the link now nothing happens, the plugin does not install. Any ideas what I'm doing wrong?
[moved to the U3 apps forum by moderator JTH. this is not related to Mozilla Firefox, Portable Edition but to the proprietary u3 package.]
You'll need to copy the DLLs manually. It's explained for the Portable version here:

Just use the location given in the U3 directions instead of the regular way.

Sometimes, the impossible can become possible, if you're awesome!
Thanks. That did the trick.
