@Rohit552,
That certainly is strange. My first instinct is that one of the extensions you have installed is causing the conflict. Can you try the following:
Try opening a Private browsing window and see if you get the same behavior there
@Rohit552 Have you tried disabling Cycle through the most recently used tabs with Ctrl-Tab? I had that feature being enabled by default at the start. You can follow these steps:-
Go to settings.
Go to the Appearance settings.
You’ll notice the option for Cycling through tabs at last. Toggle and try it again.
@ZEUSGMJ I don’t remember when this Cycle through the most recently used tabs with Ctrl-Tab flag was on. Just now i made it off and its working as expected.
Thanks for the suggestion. I’m frustrated, with this small flag till now.
@Mattches As you said, i tried in incognito. Yes, there changing tabs are working as expected.
