So I managed to fix the problem but forgot to update on it.

Apparently, it'd somehow enabled itself as a startup app, hence why it was doing this. Now, for the fix.

Basically, it's Ctrl+Shift+Esc to open the Task Manager, then from there go into the 'Startup' tab, right-click on the browser from the list and choose 'Disable'.

You may have to restart your PC/laptop in order for it to take effect, but after this I immediately stopped having this issue.

The only reason I installed this browser was 'cause of accidentally blocking Chrome through McAfee, but now that I no longer have a subscription to it, Chrome's unblocked itself and allowed itself to be used, hence, why I'm no longer using Chromium (also 'cause it gave me this issue).

Thank you for providing more feedback. Adding requester "brajkumar@chromium.org" for another review and adding "Needs-Review" label for tracking.
