@Nonas I can confirm that, flash-plugin will not load.

TbGbe · Win: Snapshot Vivaldi 7.4.3670.3

@Nonas I had a similar problem with snapshot version.
I had flash 32.0.0.238 installed on Mint 18.3 (KDE).

I checked that flash was activated - Vivaldi Tools/Settings/Webpages - Plugins.
I also tried enabling/disabling Flash under the site settings logo in the url field.

Then I saw this post in the snapshot thread ( from @JimTDI )

I uninstalled Adobe Flash thinking it might be corrupt - rebooted - now V > Help > About > Flash shows: 999.999.999.999 /usr/lib/pepperflashplugin-nonfree/libpepflashplayer.so and now my weather radar works again. I should mention I'm on the Linux version of Vivaldi on Linux Mint 19.2, meant to mention before but not enough coffee yet today

I guess I'll leave it with the pepperflashplugin unless there's a good reason not to. I don't understand the 999 looking IP address in front of the information for the plugin though.

So I also uninstalled the flash 32.0.0.238 plugin.
On restarting VIvaldi; Help/About shows Flash 999.999.999.999 /usr/lib/pepperflashplugin-nonfree/libpepflashplayer.so

Now flash works for me - in both Snapshot AND Stable!? (Checked on https://helpx.adobe.com/flash-player.html which says I now have Flash version25.0.0.171 (??); just scrolled down the page and am able to see the animation).

Maybe there is an incompatibility with adobe flash 32.0.0.238 on Linux?

Nonas

@TbGbe dunno if theres incompatibility with flash 32.xxx . but it did work in last snapshot, then it installed stable and didnt work, so my guess would be theres an faulty code in stable version. and i shouldnt need to mess around with flash upgrade/downgrade just to make a browser run properly, it does wotk in other broswers so fault aint on my side

Flash worked in Vivaldi 2.6.x but after update to 2.7.x it does not work anymore (Ubuntu MATE 18.04.3).
Have no idea what broke it, but suppose it's Vivaldi that (AGAIN!) broke functionality.

Adobe Flash Player is installed, Vivaldi -> Help -> About says:
Flash: 32.0.0.238 /usr/lib/adobe-flashplugin/libpepflashplayer.so

Tried workaround suggested by TbGbe => does not work
Installed Flash Player again => does not work
Used Synaptic for removing / reinstalling Flash Player => does not work
(after each try, rebooted the system)

Tools -> Settings -> Webpages

Enable Flash Plugin is checked

Right-click to run Adobe Flash player -> Run this plugin => does not work

Installed Flash Player via Ubuntu MATE Software Boutique => works in Firefox; does not work in Vivaldi

@Gwen-Dragon: I can confirm that this works! Thank you for the workaround

Ubuntu MATE 18.04.3 - Moved all the Flash related files downloaded and un-zipped to the /opt/google/chrome/PepperFlash/ folder (as root) and restarted Vivaldi... WOW! Flash works in Vivaldi now

Hi!, greetings. This issue happened me too in Debian 8. After upgrade Vivaldi to 2.7, updaded the Flash Player to his last version (32.0.0.238). I tried to uninstall the Flash Player and reinstall, but nothing happened. However, tried to reinstall the older version that I used before (32.0.0.207), nothing changed. I found an alternative way to solve this, running Vivaldi with "vivaldi --no-sandbox", and works to me. Also, this temporal solution has used in Google Chrome and Chronium in this issue: https://bugs.launchpad.net/ubuntu/+source/adobe-flashplugin/+bug/1826739.

I don't know if this help. Sorry if my English isn't very good.

P.D: In this screenshot, in a Vivaldi launcher, I wrote in the end "--no sandbox", it is a better way to start Vivaldi that to go to the console and write "vivaldi - no sandbox", as in the other screenshot.

Debian 8 is a version which will get only few core security fixes, but not on all packages.

On my Debian 9 i downloaded the Flash Player with this unofficial script latest-pepper-flash..sh from https://gist.github.com/ruario/215c365facfe8d3c5071.
I used the script in a daily cron job.
And Flash Player worked on Vivaldi without any commandline parameters.

I did that as well, and got it working. I'm on Linux Mint 19.2.

I did have to do one extra step. I already had flash installed and even after running the script, Vivaldi would load using /usr/lib/adobe-flashplugin/libpepflashplayer.so

So, I renamed, /usr/lib/adobe-flashplugin/libpepflashplayer.so to /usr/lib/adobe-flashplugin/libpepflashplayer.bak

And now Vivaldi starts using the version from the script in /opt/google/chrome/PepperFlash/libpepflashplayer.so

@ugly This technique works for ubuntu 16.04 also.

@Gwen-Dragon Why do you think this is an OS problem?

I'm using Fedora 30, I'm facing the same problem.

I'm using Flash from the official Adobe repository. Last update was 2019-08-13.

Flash was still working after this update. But since I updated to Vivaldi 2.7 today, Flash stopped working.

The Workaround uninstall Flash from Adobe repository and install PepperFlash via Script is working but not really neat.

@OctalVolt I think it is a problem of packaged lib libpepflashplayer so.

Here(debian testing) is working with
Vivaldi 2.6.1566.51 (Stable channel) (64-bit)
and, after vivaldi update, not working with
Vivaldi 2.7.1628.30 (Stable channel) (64-bit)
that says in console:
ERROR:chrome_content_client.cc(347)] Failed to locate and load the component updated flash plugin.
ERROR:ppapi_thread.cc(315)] Failed to load Pepper module from /usr/lib/adobe-flashplugin/libpepflashplayer.so (error: /usr/lib/adobe-flashplugin/libpepflashplayer.so: cannot open shared object file: Operation not permitted)

I think that something flash related as changed in 2.7 version.

Edit: I can workaround with
$ export LD_PRELOAD=/usr/lib/adobe-flashplugin/libpepflashplayer.so; vivaldi

Sorry for resurrecting a half-year-old thread, but this bug is still present in Linux Mint 19.3 fresh install, Vivaldi 2.10.1745.27.
Only other chromium-based browser I tested is Opera (66.0.3515.72) and flash works fine there.
Disabling sandbox with --no-sandbox option makes flash plugin work in Vivaldi, but AFAIK it is generally a bad idea to run a browser with sandbox disabled.
Currently I was able to work around the issue bu uninstalling adobe-flashplugin and installing pepperflashplugin-nonfree which is not the best option for end-user. The former updates flash plugin automatically via apt, while with latter you have to update the plugin manually.
It would be nice to know if there is a fix or should we stick to workarounds mentioned earlier?

petroid

Well thank you for prompt answer. Guess workarounds are what we'll have to cope with.

Anyway, I still don't get why does flash plugin work in Opera and does not work in Vivaldi. Opera does not maintain a flash player package too. It loads any installed one from pre-set paths. The chromium codebase should be roughly the same. So what's the difference?

It is a bug in Ubuntu/Mint https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1825497

Yes, I've read that. There WAS a bug in chromium-browser. By the way, among other they advise against --disable-seccomp-filter-sandbox from security point of view.
