https://blog.torproject.org/ covers what to do for Tor things.
For everything else on the net, fix the clients and servers you're
responsible for. Then...
You're right, there's a big gotcha in all this, users won't really know if
the services they interact with have been fixed  because huge swaths
of services simply don't publish what they do on their pages, they bury
it to keep quiet and shiny happy sites. Only some banks, insurers, utilities,
schools, etc will post "we're fixed" anywhere remotely prominent. So
you have to trust they did , which is a reasonable assumption given
regulation and liability of big institutional services. You should already have
a regular password changing/logout/session management regimen, so
inserting some extra instances of that along guesstimates of  should
suffice with these classes of service.
 Sometime during the falloff curve starting yesterday afternoon.
The real user risk is likely on mid to small services, embedded things, shared
platforms, legacy systems, services that didn't get the news, don't have
the resources or knowledge to fix, etc. Again, consider some form of
And there are all sorts of tools and site testing services coming out
now for which a brave user might be completely warranted in using to
determine [1 above] so they know when to utilize [regimen 2].
(Far better to use a testing service or email their help desks seeking
a positive statement than risk being potentially considered an exploiter
of things you don't own.)
(Note, this is a TLS in process bug, so more than HTTP/S services are
This bug will no doubt trigger some thinking, analysis and change in
security, infrastructure and user communites... that's a good thing.
