Microsoft Edge PDF Reader - signature validation warning for official signatures
Since the last edge update we are running into the following issue, which triggers lots of support tickets on our side. It seems that the edge internal PDF Reader now supports validation of digital PDF signatures. This new feature however is incomplete and causes a lot of confusion for edge users. "Official" signatures are labeled as "Unknown Signature" and "The validity of the signature is still unknown": "Official signatures" means qualified signatures from members of the EUTL - the European trust list as defined in ETSI TS 119 612 („Trusted Lists“): [...] the European Commission publishes a central list with links to the locations where the national trusted lists are published as notified by Member States. This central list, called the List Of Trusted Lists (LOTL), is available in both a human readable format and in a format suitable for automated (machine) processing XML. Parts of the edge PDF reader seems to come from *dobe itself which adds additional confusion since in their products (*dobe reader, acrobat etc) the signatures are correctly verified. They support this list for several years now (next to their own AATL list). I tried to find out whether this feature is 'work-in-progress' or it is a bug however the last published roadmap is quite old and doesn't give helpful information regarding this aspect. So my question is: Is full support of PDF signature validation including support of the EUTL planned and if so when?
Edge Pdf Viewer does not support page=Fit (only FitV or FitH works)
Dear community, I found that the Edge Pdf Viewer does not allow to display a pdf so that its first page fully fits into the window (no part of the PDF is out of the viewport). You can use the following URL to verify: https://creativelab.berkeley.edu/wp-content/uploads/2019/12/1920X1080-HORIZONTAL-template.pdf#page=1&view=Fit Test Case 1 When the window width gets too small, the window will display a horizontal scrollbar instead of scaling the pdf to fit the width: Test Case 2 When the window height gets too small, the window will display a vertical scrollbar instead of scaling the pdf to fit the height: When I use either FitV or FitH, the respective behaviour is as expected. But I need to combine both behaviours, and thus Fit would be the right option, which seems to be ignored by Edge. When I test the same parameters in other Browsers that use a Chromium engine, it works. Microsoft Edge Version 141.0.3537.85 (Official Build) (64-Bit) Windows 11 Thanks for any advice and thoughts! If there is a dedicated place to create a bug report, please let me know.
Edge Read Aloud feature fails on landscape PDF documents with tables.
I've encountered an issue with the Read Aloud feature in Microsoft Edge when opening PDF documents in landscape orientation that contain tables. The Read Aloud option is available and can be activated, but it gets stuck loading indefinitely and never starts reading. No error message is shown. In contrast, the same feature works perfectly with portrait-oriented PDFs, even when those PDFs include tables. I tested this on both Windows and macOS with up-to-date Edge versions. The issue appears to be consistent and not OS-specific. My clients use tables in landscape PDFs for better readability and formatting. It’s unclear whether the problem is due to the landscape orientation alone or the combination of landscape + tables. However, tables in portrait PDFs do not cause any issues. Has anyone else experienced this behavior? Is there a known fix or workaround? Would appreciate any feedback or confirmation from the Edge team.
