I should write everything down before i forget!!!
First install the latest firefox.
Download the Google Toolbar latest xpi file.
Open install.rdf file and modify the max version to whatever you want and save.
Open Lib/toolbar.js, find www.google.com/accounts and replace all with accounts.google.com and save.
Go to the top level as if the install.rdf remains on the top level.
Delete META-INF folder.
Select all and zip it, but in the location of the zipped file, place it one level up and put *.xpi as the extension.
That will do the trick.
Previously i did the trick, but every time i modified an extension, i always ended up with an error message saying, the addon has been corrupted, until i found the two articles in StackOverflow which made me understand the problem.
One last thing as i mentioned in my last post.
Firefox 23 and 24 are causing problems with new tabs if you have a toolbar installed. Getting rid of the toolbar is naive way to get rid of the problem.
Just set browser.newtab.preload to false in your about:config to fix this issue.
I will be uploading a new version of Google Toolbar compatible up to Firefox version 32, within a few while, In Sha Allah.
