Seamonkey starts coredump after opening multimedia link

I installed Seamonkey 2.53.15-1.8-x86_64 a few weeks ago. When I open links in a new tab and click on this tab, Seamonkey crashes and in the journal I sea a coredump started.

What happens?
Open youtube.
Open youtube link in new tab
Click on tab.
Seamonkey freezes.
Seamonkey disappears.
Looking at journalctl coredump ends with these lines

This seems to happen with every page with multimedia on it that directly wants to start. Newspaper sites have adds on them. When they become visual the multimedia starts and Seamonkey crashes.
Opening a youtube video crashes Seamonkey for sure.

Today opensuse update with about 3700 packages. Including a new Seamonkey update to seamonkey-2.53.15-1.14.x86_64
Directly after reboot I tried Seamonkey and youtube. No difference. Start Youtube, no problem. Opening a video, crash.

I have made a bug report. But not a lot of problem solving reactions. the link: Bug 1208396 – Seamonkey starts coredump after opening link in new tab
I like Seamonkey and I really want to continue using it. What to do?

No such problem with either of my SeaMonkey profiles, but mine comes from upstream directly here:
https://archive.mozilla.org/pub/seamonkey/releases/2.53.15/linux-x86_64/
I’ve been using this installation method since before it acquired its current name, which had been Mozilla, from which Firefox was forked.

Also, I’m running it on Leap and haven’t tried on TW…

If using extension(s), which one(s)? Have you tried disabling any or all of any you do have?

I use a tumbleweed source
https://download.opensuse.org/repositories/mozilla/openSUSE_Tumbleweed/

I didn’t try to disable any exentions. Good tip. I try that later tomorrow.
I have all these extensions for a long time and never had a problem. But it’s good to try if this resolves my issue.

Disabled all add-ons, no change. Still crashes in various situations.

I have the same issue, Seamonkey crashes on various web pages. I was also disabled all addons and it did not help. Look like it started happening after latest updates. I experiencing this issue on Leep as well as on Tumbleweed. Any help is much appreciated.

Does it also happen with the seamonkey version from the OSS repository instead of the one from Mozilla repository?

In my case it is installed from OpenSuse repository. I did not insalled seamonkey from other sources.

Today I was trying to find any consistency in browser crash. I have two example URL’s. On following one seamonkey just crashes with memory violation exception:

On the following URL: Centrum24 - Logowanie | Santander Bank Polska (dawniej BZWBK), it crashes with additional information:
WebGL(0x7f4a51953000)::ForceLoseContext
WebGL(0x7f4a56740800)::ForceLoseContext
I hope it will be helpful to investigate further. In case there is a need for additional information, just need instructions what to do.

I updated today to seamonkey 2.53.15-1.16. I tried opening a youtube link again and seamonkey still crashes.

Same here using 2.53.15-1.2-x86_64 from the Tumbleweed OSS repo. No extensions added.

Today I installed version 2.53.16-1.1. Opening links of Youtube works again. Just tried a few minutes ago. Still have to try other sites. But happy already.
