Description

[Jacob Smith]

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9b3) Gecko/2008020511 Firefox 3.0.2b

I updated from FF 3.0.2b to FF 3.0.3b; I use the Flashblock extension which is marked in its install.rdf as compatible with "maxVersion 3.0.*". For some reason the upgrade from FF 2b to FF 3b disabled this extension; however, the extension works just fine with FF 3b.

Re-enabling this extension is a Herculean task. There should be (at least) some sort of "right-click-force-enable" option for when FF gets this sort of thing wrong.

Reproducible: Always

Steps to Reproduce:
This is how you re-enable the Flashblock extension that FF has accidentally killed:

0. Close FF
1. change maxVersion from 3.0.* => 3.*
2. remove extensions.cache
3. find the file "extensions.rdf"
4. search for "appDisabled" xml-tag; change from "true" to "false"
5. save the file
6. start FF and enjoy no-Flash irritation
Actual Results:  
Flash is blocked. Flash is annoying and responsible for Global Warming, the suspension of Habeus Corpus, a minor loss in momentum of the Moon, and general decline in the quality of Protons throughout the known Universe.

Expected Results:  
At the very least? High quality Protons.
