I recently downloaded Firefox 6 Aurora (alpha). But this version does not have Firebug extension compatible with it. I cannot re-install Firefox 4 as it's download is blocked (company policy). Is there any way I can revert to firefox 4 by means of updates?

Thanks. Sid

This question came from our site for professional and enthusiast programmers.

Those Firefox folks are completely off their rocker nowadays. Firefox 5 isn't even ready for release yet. Why are they dedicating resources to developing version 6? You're not going to beat Chrome by screwing up priorities. – Cody Gray Jun 2 '11 at 17:07
Stop trying to circumvent IT policy at your workplace. At worst you'll be terminated, at best you'll piss off the people that control your access to everything. – MDMarra Jun 2 '11 at 17:10
Install Firefox 4 just like you did it the you installed it the first time? – Daniel Beck Jun 2 '11 at 17:37
@Daniel Beck - First time when I installed Firefox, it was not blocked. – Sid Jun 2 '11 at 18:30
@SidCool - Did they block your access for installing alpha software? Go back to IT and tell them you screwed up and need to install a browser that works. – P.Brian.Mackey Jun 2 '11 at 18:37

No, unfortunately this is not possible. There is no way to "update" from Firefox 6 to Firefox 4.

Not only does that defy intuition (such would not be an update!), but it's technically impossible as well. The code base for version 6 is undoubtedly very different from the code base for version 4.

Download and install version 4 the same way you were able to download and install the alpha release of version 6. That wasn't an in-place upgrade, either. Use the same methods to get around your company's security policy, or ask your administrator to do so for you.

Normally different Firefox version are installed side by side. Maybe you still have Firefox 4 on you drive?

If you could edit your answer to say where he might look for the older version, that would probably be helpful. – nhinkle Jun 2 '11 at 21:49

I think you can get Firebug for that verison of Firefox:

It did not work. It still says Firebug is not compatible. – Sid Jun 2 '11 at 18:31
Ok, sorry. Then I don't know. – Dusty Campbell Jun 2 '11 at 21:49
But thanks, anyway. – Sid Jun 3 '11 at 15:33
