I’ve had an email from the bug tracker saying this has been fixed now.
As mere mortal user with no coding ability or real grasp of how open-source development works, can I ask how long it will be before the fix is available in the Windows AIO package?
Yes, the update means the report no longer crashes but it still doesn’t work because the problem as given in my original post still persists.
Namely that the local workaround for “Charts appearing without content - related to a security vulnerability update to Browsers. (i.e. local HTML files ought not to be authorized to open files from different sub-directories)” no longer works in Firefox. Nor can I get the report to work using Edge.
NB my mention of using Edge should make it clear that I’m using Gramps on Windows (both 10 and 11).
I just loaded Firefox 137.0.2 on my Mac and followed the instructions in the wiki page, going to about:config and setting security.fileuri.strict_origin_policy to False.
I then opened the Ancestral Fan Chart and it had the expected content. I then tested the other two reports (Ancestral Collapse and Descendant Indented Tree) and they also had content.
So everything worked fine with the latest Firefox on a Mac (once the browser config was set as described in the Addon wiki page).
No as pointed out in the linked issue 9602: [Upstream Browser Security Change]HTML & SVG generated report doesn’t work for local file system with browser
This is how browsers are by default now due to an upstream browser security change!
