Opening website http://iantiqueonline.ning.com causes hundreds of lines output to syslog
 

When opening the above website in Firefox, I have the latest installed 53.0.2, I have hundreds of lines shown here - https://pastebin.com/apUuaD1D written to my syslog. I installed the latest Chrome this afternoon and loading the site does not cause the problem. My system info

Ubuntu 16.04.2LTS

I opened up a VM of Ubuntu 16.04.2 LTS, but was unable to duplicate this problem.

I will note that Ubuntu in the VM is updated and is plain vanilla Ubuntu everything at default and no additional applications installed. (I keep it around just to be familiar with Ubuntu.)

Thanks Frank, I've found that if I set the flash plugin to 'ask to activate' and load the site there's no issue. Of course once I activate flash on the site the issue starts so, flash usage on this one site causes this problem. I haven't noticed any issues on other sites using flash.

Thanks for the update. I didn't try anything with Flash. I just hit the site.

I may give it another shot tomorrow; it's getting late here.

Thanks Frank, appreciate it.

Here's what I did:

I installed Flash by downloading the *.tar.gz from Adobe, decompressing it, and copying libflashplayer.so to /usr/lib/mozilla/plugins. (This is my standard way of installing Flash.)

I then tested Flash at a site specializing in Flash videos and ensured that Flash was working with Firefox.

I exited Firefox, reopened it, went to the antiques website, and then tailed /var/log/syslog.

I repeated this several times. I was unable to generate any errors similar to those you posted to pastebin.

Darnit.

If there is particular Flash link on that website you'd like me to test, I would be happy to do, but I fear this one is beyond my level of competence.

Thanks so much for trying Frank. Looking in /usr/lib/mozilla/plugins I had the file /usr/lib/mozilla/plugins/Hold/flashplugin-alternative.so. Note-It's in a 'Hold' folder now since I went to the Adobe site and downloaded the same file you did and put the actual libflashplayer.so file in it's place. I did the same as you and went to a site with flash videos and tested that it was working. Went back to the antique site and activated flash there and still I get the lines of output as the original post. I can get by without using flash there since I mostly post questions about some of my antiques but I'm still mystified as to why it happens on only this one site. I found several flash links in the page source but have no idea which one could be the issue however when I activate flash on the center of the page for photos the entries to syslog begin.

I also would like to know what the heck is going on here. I was hoping that, but installing Flash, I'd learn something, but I didn't.

I hope that someone who can enlighten us stumbles over this thread.

i think you should notify firefox developers (bug report?).
it isn't so long ff changed its ui to gtk3, there might be somebumps to smooth out.

Thanks for the suggestion, I'll go in and do that sometime today. I've already got an account at Bugzilla so it's just a matter of filing it.

I submitted this bug report-https://bugzilla.mozilla.org/show_bug.cgi?id=1363494 today.

How was it installed? and is it in really?
Also output of
Thank you.

Nevermind. You are tracking down flash stuff, I guess.

Peace.

Installed via Ubuntu Software Center and yes, it's in ~/firefox.

Chris:

In 10 years of Debian/Ubuntu, I have never seen such a .deb installation put the package in ~/firefox
How did it wind up in /home/chris/firefox/ please?
Was it moved/copied/symlinked?

If this is a "side-by-side" OR a parallel installation of Firefox for reasons known only to you, that's fine.
but it's my estimate that running firefox from /home/chris/firefox/ is causing your syslog to fill up.

You can compare where the package manager thinks the stuff should be going (determined by controls in the .deb)
using
If you suspect there are 2 firefox binaries floating around, ask the system using
spews here
Compare that to:
tells us the package maintainers use dpkg to put it in /usr/bin/
and that is where is should go. IMO.

See if there is also a
and if there is, run it and check syslog.
The Menu items from the system should also use the correct location of the binary, IMO.

Good Luck.

Possibly I was mistaken on how I installed then. I may have downloaded and installed from the Mozilla website. Here are the outputs of your questions

In my internet menu I have three entries for Firefox. One has the command as

/home/chris/firefox/firefox %u

Then there's and entry 'Firefox Web Browser' with the command firefox %u and finally there's
'Mozilla Build of Firefox' with the command firefox %u clicking on either of those entries puts this in my syslog - gnome-session[3442]: Couldn't load XPCOM.

Hopefully this was some help
