libfreshplayer does not show up in Firefox 69.0.1 64bit #384

Closed TrIPpY- closed 4 years ago

TrIPpY- commented 4 years ago

Hello,

Followed the build and install procedure from README.md libfreshwrapper-flashplayer.so is in /usr/lib64/mozilla/plugins, /usr/lib/mozilla/plugins and ~/.mozilla/plugins. It does not show up under plugins in firefox. Hope there is something that can be done.

Thank you.

First, the version of Firefox looks unusual. It's not an extended support release which I believe is 68. But it's also not the current version, which is 74.

Since Flash is almost gone from popular websites, I don't really use it. So I can't say for sure if freshplayerplugin was working in 69.0.1. It works on 74.0 though.

As for the possible reasons, it may be pluginreg.dat file contains stale data. If for some reason plugin crashed, Firefox remembers that in pluginreg.dat, and doesn't try to load failed plugin again. Sometimes it helps to stop the browser, remove pluginreg.dat, and start the browser again. File is located in your profile directory. You may find where it is on about:support page, search for "Profile Directory".

Another reason is freshplayerplugin built in previous versions of an OS. If it's not fresh-built, it may help to build from source again. Also freshplayerplugin loads PepperFlash itself, so your system libraries should be relatively recent. PepperFlash from desktop Chrome usually works on almost every distro versions, but if you use PepperFlash from ChromeOS, you may need recent libc and libstdc++.

Thanks very much for your answer.

Yeah sorry i'm on 73.0.1 now. Freshly installed fedora 31 workstation but had not updated for the first time.

Removed pluginreg.dat

Started fresh, did the: cmake thing, make and make install.

copied libfreshwrapper-flashplayer.so to several locations including where the firefox rpm installs firefox

so it's now in:

/usr/lib64/mozilla/firefox/plugins /usr/lib/mozilla/firefox/plugins /lib64/mozilla/firefox/plugins /lib/mozilla/firefox/plugins /usr/local/lib/mozilla/plugins /usr/local/lib64/mozilla/plugins ~/.mozilla/plugins

and where about:support says the profile directory is: ~/.mozilla/firefox/2vq1u8b3.default-1517998618273-1526802550388

It still doesn't show up in firefox plugins.

Even if the libpepflashplayer.so can't be found freshplayer should still show up in firefox, right?

fedora 31

As far as I know, Fedora uses SELinux. So it could be lack of SELinux policy that prevents library from loading. I'm not familiar with SELinux enough to check if that's the case. I usually just disabled it completely, but that was for testing purposes. The right solution would be to add a policy.

Yeah, it should. PepperFlash is loaded dynamically, so it should not prevent freshplayerplugin itself from loading.

@i-rinat There is an amazing project that will make any SWF made the last 20 years working for ever on the net. https://github.com/ruffle-rs/ruffle contributors are welcome!

Thanks again. With selinux disable it also doesn't show up in firefox.

@TrIPpY- check the right permissions of your libs

They are mostly all rwxr-xr-x

OK, I've tried to install Fedora 31 into a virtual machine. And indeed freshplayerplugin doesn't show up in about:plugins in Firefox. It's not permissions or SELinux interfering, it's just Fedora 31 have Wayland session enabled by default, and uses custom Firefox build with Wayland support enabled by default. As NPAPI plugins are tightly bound to X server technology, there is no way to support them in Wayland-enabled Firefox builds. So, plugins do not work there.

If you still need plugins, you have to run Firefox as GDK_BACKEND=x11 firefox. It will then work through implicitly started Xwayland. Or you may download Firefox build from Mozilla's website. While it supports Wayland too, it still uses X11 backend by default.

Ah. makes sense. Few versions back Fedora introduced wayland. I have this problem since 27 or 28.
