I'm on Firefox 41.0b1, how do I go back to version 40?
Since upgrading to the firefox 41.0b1 my fluff buster purity doesn't work on facebook. Fbb states they do not support firefox 41--- at this time so I would like go back to the version that they do support. If I can't keep facebook clean and simple I may be forced to try a different browser.
According to this previous topic, you can install both the Beta (41.0b1) and the current release (40.0.2) on the same computer, most of the time without interference.
As a precaution, consult advices given in the mentioned topic above.
