To save space I cannot upload the thumbnails, they are small though, same size like windows thumbnails. Since the fallback is alt='' is empty you will stare at a blank black page.

If you had the thumbnails only 197 of the 249 would render.

The bug is reproducible on the current Android nightly too. It seems to affect all current channels.

If Firefox doesn't want to lose more than it's tiny 11.7 % desktop market share it is a call for action to fix this.

Remember, it works on chrome. I cling to Firefox, but trivial issues like these should not happen at all!

I created a tester with demo thumbnails.

This is reproducible using the test file in comment 3. Firefox shows 197 while Chrome shows 249.

The DOM parser depth is capped at 200 to avoid stack overflows in some systems (particularly win32). Bug 256180 tracks changing that. Chrome just lets the stack overflow and crashes.

In any case, you probably want to use <p> instead of <pr> tags, or close your <pr> tags in your page, or something. There's no need to be as rude as comment 2 :)
