Seems to be so far. Then again only had it installed for about 45 minutes. Could be my imagination but it does seem that most sites are loading quicker now, especially a few that I visit that have a tendency to hang for a few seconds or more.
All of mine seem to be working as they should. Most of them were declared incompatible, but a quick visit to about:config and adding the following (new boolean),
extensions.checkCompatibility.4.2a
and setting it to false, and they were all re-enabled. Still showing as incompatible in the Add-ons manager, but they are working.
