Many of you who will be working on firefox 3 beta 5 will be having problem’s to configure the plugin’s coz they are not compatible with firefox3b5,
YOU Don’t Need to wait til the official release you can try on your own that are the really not compatible with ff3b5
=== rest of the section is not for fainthearted people ===
The plugi’s of firefox are provided in .XPI package.
This xpi is nothing but a zip file renamed.
so to view the content of the plugin’ just change the extension to zip from xpi.
The extract the file in a folder and look for a file named “install.rdf”
This is the file that need editing
Pasting a sample install.rdf from sparky - an alexa plugin
<?xml version="1.0"?>
<RDF:RDF xmlns:em="http://www.mozilla.org/2004/em-rdf#"

</RDF:Description>
</RDF:RDF>
The lne to check out is already highlighted
em:minVersion=”2.0″
em:maxVersion=”2.0.0.*” />
This minVersion is the version number below which it will not install and maxVersion is the upper limit
To make it running on FireFox3 Beta 5 change the above lines to
em:minVersion=”2.0″
em:maxVersion=”3.0b5″ />
After this just recompress the folder and rename it with extension xpi.
and open it in firefox to install it.
more examples of such edit includes firebug and scribefire.
all three plugin are working fabulously on my pc and i keep using them around 12hrs a day so that can count to the stability issue.

You’ve managed to explain a really tricky subject well. Thanks

Sorry, did a test but it does not work.

Sorry, did not work. Says it is illegal addon file.

… or, get the “nightly tester tools” extension and disable version checking. Tada!

Looks quite tricky and useful but comments came as ‘It does not work’ please verify it quick and let me try.

Or you can use about:config (in your FF adress bar) and add:
extensions.checkCompatibility boolean false
