html.elements.frameset - <Full support for frameset ceased to exist. The table however insists there is full support in Firefox.>

[pbdown]

What type of issue is this?

Incorrect support data (example: BrowserX says "86" but support was added in "40")

What information was incorrect, unhelpful, or incomplete?

The compatability table for frameset claims full support for frameset in firefox. However, in the latest Firefox browser release, 134.0 (64 bit), hyperlinks with a target framename do not work anymore. UNFORTUNATELY!

Therefore, this claim of full support in Firefox should be retracted from the frameset page.

What browsers does this problem apply to, if applicable?

Firefox

What did you expect to see?

I expected to see a selected link appear in a frame.

Did you test this? If so, how?

I have an old set of html pages that until very recently worked very fine.
It consists of a frameset with a left and right frame. The right frame contains a table of contents, the right frame is supposed to show the selected item from the table of contents.
Since upgrading to the new Firefox (automatic upgrading is enabled in my system) this set of html pages ceased to work.

Can you link to any release notes, bugs, pull requests, or MDN pages related to this?

No response

Do you have anything more you want to share?

This will not be helpfull, but I must get it off of my chest: redesigning from frameset/frames to iframes is not a trivial task. And in some cases impossible. Iframes lack the simplicity of frames. Many glitches and anomalies (browse bars, data disppearing from view, etc, you name it ) on modern websites I do attribute to the clumsy design of iframes.

Sorry: I meant the left frame contained a table of contents.
