Compatibility with Nightly Build? Rated 4 out of 5 stars

Worked perfectly with Nightly Build until this week 12.01a - now does not retain per page zoom at least on what I need (Financial Times). Default text now way too big. Very annoying. Not sure if it is site or Nightly.
Others seem sort of ok but uneven - sometimes yahoo mail is also too large vs the per page setting. Any others having the problem?????

This review is for a previous version of the add-on (4.6.1).
