Rated 5 out of 5 stars

Session Manager is by far the best, most useful add-on I have used on any browser ever - but I can no longer use it due to the automatic update to FF 57. Session Manager is hugely important for my work and browsing experience. My ability to use FF is now severely hamstrung. We must all make every to keep this great add-on compatible with FF and usable for the community. I hope FF see sense and enable compatibility for FF 57 with Session Manager.

A call to arms: as a community we have to ensure ourselves that this issue is fixed. Another user in the reviews below has suggested we encourage/pressure the FF developers into fixing this by voting on the relevnat bugs on Buzilla. Please create a Bugzilla account and vote on the following by going to the "Details" and click "Vote" (and then select the bug and click "Change My Votes"):

Thank you for your previous work, Michael, and I hope we can continue to use Session Manager on FF in the future!

This review is for a previous version of the add-on (0.8.1.13).
