Chrome and Chromium no longer fully support Flash by default, due to security concerns.
The announcement was already made some time ago:
2016 - Google plans to start blocking Flash in Chrome this year
Flash's death has been slow and painful, and now Google is planning to
deal it another blow. Google has detailed plans to start blocking most
Flash content with Chrome, with the change targeted toward the end of
this year.
Under its current vision, nearly every website would have Flash
content blocked by default. Visitors would still be able to enable
Flash content on a site-by-site basis, but they would have to
specifically choose to do so. Chrome would display a prompt offering
to enable Flash; if chosen, Chrome would remember to run Flash on that
site for all future visits.
THE TOP 10 SITES WITH FLASH WILL GET AN EXEMPTION
Only 10 sites would have Flash enabled by default — the "top 10
domains using Flash," to avoid annoying people with too many prompts.
Those include YouTube, Facebook, Yahoo, Twitch, and Amazon. But
they'll only have a one year exemption. After that, it sounds like
they'll have Flash blocked by default, just like everyone else.
and from Google blog Aug 2016:
Today, more than 90% of Flash on the web loads behind the scenes to
support things like page analytics. This kind of Flash slows you down,
and starting this September,Chrome 53 will begin to block it. HTML5 is
much lighter and faster, and publishers are switching over to speed up
page loading and save you more battery life. You’ll see an improvement
in responsiveness and efficiency for many sites.
This is similar to a change we made last September, when some Flash
content became click-to-play with Chrome 42. This had an immediate,
positive impact for our users by improving page load times and saving
battery power.
So I would say to Flash, so long, and good riddance.
If you still have legacy sites, or network enterprise equipment/VCenter devices that need Flash functionality, the path of least resistance is to open them with an alternative browser, like Firefox, where it seems more intuitive to enable flash for the exception.
However, all the major browsers they are on the same page, so if internal developed sites, I would advise to upgrade them to a newer technology; if need be to keep access to legacy hardware, better keep a VM with and old version of a supported browser.
Aug 2016 - Firefox is latest browser to kill off Adobe Flash support
Meanwhile, Firefox is beginning the process with a curated blacklist
of sites that can work without the Flash plug-in, expanding to become
a 'click to run' model for all content during next year.
Mozilla has already confirmed that, like Google, it will abandon
support for all NPAPI (Netscape) plug-ins other than Flash from March
2017. This effectively kills Silverlight and Java too, although an extended support release will be available until 2018 for those
needing a little longer.
The need to kill off Adobe Flash has long been recognised. The player
required 78 patches in December 2015 alone to cover security bugs in
the code.
Unfortunately, I am no longer using SuSE, would say to check this page as soon it goes out of maintenance mode https://software.opensuse.org/package/chromium-pepper-flash , because I suspect the package may be discontinued too.
