Chrome extension versions after 26.5.2 are causing sites to not be able to open PDFs

Hi ​@Amal Jaiswal and ​@__Gaurav_ ,

The website is https://www.aiready.com/ConvPdf/ and it is publicly available. Our version of Chrome is 151.0.7922.76. This is happening on every machine running Adobe extensions later than 26.5.2.
I am more than happy to join a screen share to reproduce the issue with you. I am unable to share a specific file at this time due to NPI. I am trying to locate a dummy file we can use.

Hi ​@jstatus10 ,
Additionally, if the PDF or the website used to generate it is publicly accessible, could you please share the URL (if you're comfortable doing so)? Having access to the same workflow would greatly help us reproduce the issue and investigate it more effectively.

If the URL cannot be shared publicly due to company policies or internal access restrictions, that's completely understandable.

Also, if it's convenient for you, we'd be happy to connect over a quick call or screen-sharing session to better understand the issue and work towards a resolution. We're committed to investigating this thoroughly and appreciate your help in reproducing the problem.

​Hi @jstatus10 ,

Thanks for reaching out, and sorry for the disruption, especially given that this workflow had been running fine for 10 years with no changes needed on your end.

This does sound like a regression tied to the last couple of extension releases (26.7.x.x and 26.8.1.2) rather than anything wrong with your setup, since the same workflow worked cleanly on 26.5.2 with default settings. The fact that turning off "Allow access to file URLs" for the extension and disabling "Online PDFs" under Open PDFs in Acrobat from your browser in Acrobat Preferences gets things working again strongly suggests one of these recent updates changed how the extension requests or intercepts files, likely a permissions or file-handling change that slipped into 26.7/26.8.

A few details that would help:

• Whether the site your company uses is public or requires login/internal network access, if it's public, sharing the URL lets Adobe try to reproduce it directly.

• Your exact Chrome version, since browser-level changes sometimes interact with extension permission behavior too.

• Whether this happens on every machine running 26.7.x.x/26.8.1.2, or only some.

In the meantime, since you've already found a working combination of settings, sticking with "Allow access to file URLs" off and "Online PDFs" off sounds like a reasonable stopgap.
