1336976 - Firefox 51.0.1 painfully slow and laggy on macOS 10.12.3 to the point of being unusable!

Status: RESOLVED INCOMPLETE

(Firefox :: Untriaged, defect)

Description

[Mike]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_3) AppleWebKit/602.4.8 (KHTML, like Gecko) Version/10.0.3 Safari/602.4.8

Steps to reproduce:

Ever since latest update Firefox is painfully slow for all web access!


Actual results:

Pages take a long time to load or do not load at all


Expected results:

Expect pages to load seamlessly as they do in other browsers on bearing in mind we have a 100mb leased line!

Do you have multiprocess (e10s) enabled in your profile? (about:support > line "multiprocess windows")

Tested on Mac OS X 10.12 with FF release 51 and FF Nighlty 54.0a1 and I can't reproduce the issue. 

Please test if the issue can be reproduced in the safe mode of Firefox: https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode
Please download Firefox Nightly from here: https://nightly.mozilla.org/ and retest the problem.
