I just upgraded to the new FF 6.01 and I don't like the way it is laid out and want to go back to the previous version. How do I do that without completely uninstalling FF completely? HELP...Please tell me how to accomplish this> Thanks

Well it is not like you're upgrading! You're downgrading your browser!!!

But don't worry, downgrading process is just like upgrading. So you can install an older version without uninstalling of Firefox!


Don't forget to hit 'Solved it'.


IMPORTANT NOTE: Don't forget that the previous versions might have security problems. For the latest security updates you MUST upgrade to latest version. That's what I STRONGLY recommend. Thanks!

You can uninstall the Firefox and then install the version you want.

If you want an older version and don't have the installation file you can download all of the releases of Firefox here:

Firefox All Releases

So I have to completely uninstall the current version? Won't I then lose all the information stored in the browser, like bookmarks? Is there no way to just uninstall the upgrade?

CseC posted a link to "Firefox All Releases"... I get a 404. page not found.

I also want to roll back to a working version.

I 'upgraded' to 6.0.1 and now when I visit web sites Firefox does not mark about 30% of the pages as having been Read.

It also keeps trying to shove Google Chrome and Google toolbars at me,l which I do not appreciate.

Only because I fixed it as you have been linking to it as http://ftp://ftp.mozilla.org which would lead to http://rumba.microfocus.com/

I'D USE CHROME, BUT U HAVE TO TYPE EVERYTHING IN. I'VE USED FIREFOX FOR, SEEMS LIKE FOREVER, AND NOW IT'S LIKE IT HAS A ANTIVIRUS ATTACHED TO IT, I.E. MCAFEE OR AVG...THEY SLOW MY INTERNET CONNECTION WAAAAAAAAAAAAAAY DOWN...THANK YOU FOR NOTHING.
