Include me in this request. I don't use tabs and often flip back and forth between PDFs to check 1) before changes, and 2) after changes. In the old days, we used to do this with 11x17 outputs for creative elements.
Now, on a Mac, I use a command-tilde to cycle through the open PDFs at the same zoom level. It's a quick way to see if anything jumps around. The new way Acrobat displays PDFs on screen is to always force the document title into a very narrow tab, even though PDFs are in their own window.
Having this issue as well on a post from 2023 and now it's 2025 and still this has not been addressed?!? Will try reverting back to older version as one comment mentions below, however quite dissappointing that the latest version does not provide a resolution and instead perpetuates wasting peoples time and money.
Same issue, googled and this is the first link, without any solution 😞
Tried GPT and this is what was suggested and it solved the issue. Here are the steps
To display the filename instead of the document title on tabs in Adobe Acrobat, follow these steps:
Open Adobe Acrobat.
Go to Edit.
Select Preferences.
Choose Documents.
Under Open Settings, click Always Use Filename As Document Title.
This setting will ensure that the filename appears in the tab, making it easier to differentiate between multiple open documents with the same title but different names.
