I am not the only one to see this anomaly. Look at the page title for this page with Pale Moon:
https://www.popularmechanics.com/scienc ... ciousness/
The title shows as it should with the other browsers that I use, but not with Pale Moon. Why does it replace the title with "500 Internal Server Error"?

Same here.

No idea, aside from it being explicitly set from JS or something.

Yes, if javascript is disabled, it shows correctly.

So I was curious and followed the link. That title change happened for me as well, so I disabled js and refreshed the page and the original title did stay. The I re-enabled js, refreshed the page and the original title stayed..

Invalid URL constructor, which apparently other browsers now just ignore. Here's a Modify HTTP Response filter, but apart from the title I don't believe it's needed.

Code: Select all

[["www.popularmechanics.com",["/webpack-/",["\"x:/\"","location"]]]]

I'll file an issue. should be an easy bug to solve if the correct BZ bug is found.

EDIT: Issue #2557 (UXP)
