Firefox Hack Update: Make Book Burro work in release 3.5 of Firefox or try the new Book Burro preview

Update: There is a preview release at
https://bookburro.org/preview.xpi
It looks promising.
Here is the earlier work-around....

We cannot help you, if you don't understand the title of this post, if so, don't read it.

Book Burro is a Firefox extension that will take you to a lot of book vendors and libraries to find a book from an Amazon web page.

Have you been missing the Book Burro extension (or others that are not officially compatible) since you upgraded to Firefox 3.5?

If so, here is a hack to restore it to life from lifehacker.

• Type about:config into Firefox's address bar and click the "I'll be careful, I promise!" button.
• Right-click anywhere. Choose New>Boolean. Make the name of your new config value extensions.checkCompatibility and set it to false.
• Make another new boolean pair called extensions.checkUpdateSecurity and set the value to false.
• Restart Firefox.

Now the extensions that officially don't work in 3.5 may launch anyhow. Or if not you may need to highlight an ISBN and right click and launch the app.
