Getting the Pre-March Look Back

Update from Elmophoto: PLEASE NOTE: As of April 22, 2015 the user agent workaround for Chrome and Firefox no longer works to display the pre-March 2014 page look. Unfortunately I don't believe there's any way to return to the pre-"new experience" look..
A real pity as I liked the old Flickr look, but thanks a lot to Lorenzo Montezemolo for giving me a year's respite before being forced to give it up. :)

I just applied this fix in Firefox. Took about 30 seconds and - for me, at least - it works fine.

Borrowed from my Flickr-friend Sherwood Harrington. Thanks, Pal. :)
