Unable to change a pinned site on the default tab page

I'm a big fan of the web page shown in new tabs in Firefox, where I am able to create a grid of my most frequent sites:

The only thing I have disliked about it so far has been the 4×8 limit; I'd love a row or column more.

However, as of recently, I think a bug has appeared: I am no longer able to edit the URL of a tile.

For instance, I want to change the URL of the row 2, col 6 item:

I remove the "/content" part:

Result:

Then I click Spara (Save).

But then when I click the link, Firefox still navigates to the old URL, with "/content". And if I open the tile's properties again, I see the suffix has returned:

How to fix this? Should I edit the Windows Registry or some INI file?
