This is a post for all the firefox lovers and all of you are planning to switch to it-Go open source or or Go home(for the linux and mozilla community).

So what if you want to install a firefox add on that is not compatible with your current version of firefox.

In this post that’s exactly what we are going to figure out-How to install incompatiblle firefox add ons.

To begin with lets have a look at the error the error that I got

Note:-We’ll need to remember the version of firefox that I am using and I get from the message above.

To begin with type about:config in your firefox address(In a new tab of course)

Now Make a right click on the list select new and then boolean

We now will will asked to enter the preference name.

Note:-This is the most critical part of this firefox trick
We need to enter the exact version of the firefox that we are using.

In the preference type

extension.check.Compatibility.3.6b Remember to enter the Capital C in Compatiblity and the version of your firefox correctly

The toughest part is over.

Now in the dialog box that opens select “false” and close the dialog box.

The value we just created should now appear in the list.

Thats it now you can keep on adding add ons to current firefox installation without worrying about any add on incompatiblity issues with further version of firefox.

Their are some other tweaks to this as well ,here’s a quick description of them:-

Firefox add on’s  incompatilibility-(completely manual)

1-Download the XPI file directly (Right click on install button, save target as)

2-Unzip the xpi file using Winrar or any such tool.

3-Edit the install.rdf file – change version number to 3.6 or something else. Save file.

4-Zip the file again. Change the extension (.zip to .xpi) – Install the add-on by dragging.

You can also use some firefox add on’s  like:-

Compatibility Reporter

Nightly Tester Tools(I like this one-as makes a lot of things easier)

Both of these add on’s are good but then why not keep your firefox list to minimum?
