Kay I made a mistake with this.

And that is when I restarted the browser in Safe mode, the browser didn't crash when I accessed the FB page feed page.

Then I seen your suggestion about Shockwave being the problem.

So I disabled that and started the browser in both the Safe and Normal modes. And the above mentioned page didn't crash.

I'm sorry for any confusion that I might have caused with my first message.

And I hope that this helps.

Some parts of the web still require the Shockwave Flash plugin (Flash player), unfortunately. So I'll give you this link for future reference if you re-enable it:

Adobe Flash plugin has crashed - Prevent it from happening again

And if I might copy/paste some older advice:

While you are troubleshooting this, it might be helpful, to avoid unnecessary pain on sites where Flash is not actually essential, try setting Flash to Click-to-Play ("Ask to Activate"). This will delay Flash from starting on a page until you approve it.

To set "Ask to Activate", open the Add-ons page using either:

• Ctrl+Shift+a (Mac: Command+Shift+a)
• "3-bar" menu button (or Tools menu) > Add-ons

In the left column, click Plugins. Look for "Shockwave Flash" and change "Always Activate" to "Ask to Activate".

With this setting, when you visit a site that wants to use Flash, you should see a notification icon in the address bar and usually (but not always) one of the following: a link in a black rectangle in the page or an infobar sliding down between the toolbar area and the page.

The plugin notification icon in the address bar typically looks like a small, dark gray Lego block. When the page wants to use a blocked plugin, the icon turns red to alert you to the concern.

If you see a good reason to use Flash, and the site looks trustworthy, you can go ahead and click the notification icon in the address bar to allow Flash. You can trust the site for the time being or permanently.

But some pages use Flash only for tracking or playing ads, so if you don't see an immediate need for Flash, feel free to ignore the notification! It will just sit there in case you want to use it later.

Not a solution, but hopefully will help a bit.

If you want finer control: This extension addresses the issue of only wanting some videos on a page to play: https://addons.mozilla.org/firefox/addon/click-to-play-per-element/ (I haven't tested it recently)

jscher2000, thanks for your reply.

And it's most appreciated.

I got rid of the Shockwave player because that is what Mozilla suggested in regards to where the problem lay.

So I uninstalled it and the browser hasn't crashed since.

But should it do so again, I will definitely keep your advice in mind.

And thank you.
