Hello ,
Good to see you in Microsoft Community.
Firstly, could you let me know the specific version info of the system and the Microsoft Edge browser? Please check it and only send the relevant information without PII in the next reply.
- System version Win +R key, and type "winver", press Enter.
- Microsoft Edge browser version Type "edge://settings/help" in the Edge address bar and press Enter*.*
I have confirmed the tab behavior in the latest version of the Microsoft Edge browser (Version 118.0.2088.46 (Official build) (64-bit) ). When you select two tabs, the one that is selected is highlighted, and the unselected one appears slightly dimmed.
So the exception you're currently experienced may not be caused by the latest update, you can follow the steps below:
- Or you may try the InPrivate mode of the Microsoft Edge browser's (Ctrl + Shift + N for shortcut).
_
- Or you can Repair the Microsoft Edge browser*.* "Win" logo key + "I" open Windows Settings > Apps > Apps & Features > Microsoft Edge > Modify > Repair*.*
If anything is unclear, please do not hesitate to let me know.
