My biggest reason of not upgrading to firefox 3 from firefox 2 was 20 firefox extensions which i was using and my procastination of don’t want to spent time in upgrading them. I was happy with firefox 2.x as all extensions were working fine and many of them were not ported to FF3 and the day I found that all my extensions are now on FF 3, I immediately upgraded.

The web browser informs you that it has disabled the extensions because they are not compatible with the latest version. However, the reality is that these extensions can be made compatible in a jiffy. All you need to do is follow the steps given below

- Download the installation file of the Firefox extension from the web. Firefox extensions can be downloaded in the xpi format. Instead of installing it into the web browser, download the xpi file to your hard disk.

- Change the extension of the file from xpi to zip

- Extract the zip file and open the rdf file inside the zip file in a text editor.

- There may be two reasons why the extension may not be compatible with the web browser-

o The latest version number may not be stated in the rdf file

o The web browser itself may not be stated in the rdf file.

If you incorporate the correct version number in the em:maxVersion element of the em:targetApplication description, your extension should work fine with your upgraded web browser.

If your web browser is not mentioned at all, then you should follow the steps given below

Copy the code given below to the *.rdf file below the last

</em:targetApplication>

in the file.

 
<!—Name of web browser -->
 
<em:targetApplication>
 
<Description>
 
<em:id>{appropriate long id given below}</em:id>
 
<em:minVersion>0.4</em:minVersion>
 
<em:maxVersion>0.8</em:maxVersion>
 
</Description>
 
</em:targetApplication>

Firefox {ec8030f7-c20a-464f-9b0e-13a3a9e97384}

Mozilla Suite {86c18b42-e466-45a9-ae7a-9b95ba6f5640}

SeaMonkey {92650c4d-4b8e-4d2a-b7eb-24ecf4f6b63a}

Netscape Browser {3db10fab-e461-4c80-8b97-957ad5f8ea47}

Flock Browser {a463f10c-3994-11da-9945-000d60ca027b}

Once this is done, you can check whether your web browser works properly or not. If it works properly, then your compatibility problem has been overcome.
