as far as i know TB doesn’t update automatically to v60 so far. which means you must have done it manually… maybe mozilla didn’t roll it out to everyone for a good reason?
the common way of testing a new version is: installing it on a test-system and check it out. and then update/upgrade the working system after every test has successfully passed on the test-system. (ya, that’s a bit of work, indeed)
so why do YOU blame anyone here, at all? since i only see a lack of YOUR own responsibility here. (so much for:
)
