Sorry - didn't realise this was an actual post (it suggested I was filling in a search box), and it won't let me edit the post above.

I have a website which uses frames. It worked fine yesterday, but as of today the links to load a new html page into the main frame does nothing. Does firefox no longer support the use of frames?

I have encountered a similar problem, but it appears to be confined to links in a frame where the target is another frame in the frameset or an anchor in a current frame in the frameset. If the link is ti another frameset, it is okay, for both framesets in html or framesets where the html is generated by javascript.

Right. This is our bug that hopefully will be fixed in 134.0.2.

This issue is more of a nuisance to me than a catastrophe.

Several years ago I found a clever little JavaScript that writes a frameset page with variables for one of the frames and an anchor. I needed it because I wanted to link to an anchor in a frame, which standard html cannot do.

This latest issue turns out to be a blessing in disguise because I have started to modify my href's to point to the frameset writer which to my mind is a more disciplined approach to frames.
