According to my napkin math it would take longer than an hour if the tape was ~3.3*10^218 sec long (or three million trillion trillion… (18 trillions) …trillion years). Assuming you have only have two options to choose between but can pick which alternative in in 5 seconds (2^720) and you want to get down to a 1 minute intervall.

So i mean its not impossible to find a tape long enough though it seems unlikely that we would be so off in our estimates of the age of the universe.

If you read the report there’s both context there and also on their site mullvad have commented on the found issues stating either reasons or what they are doing to fix it.

I’ve configured it so that when i open a new tab it will by default open the url to my calendar. It does not select the url in the navigation bar, so if i want to input my own url i first need to select the calendar-url so that my inputs deletes the existing text. I do think that the custom url new-tab is an extension though so that doesn’t really help my case (not at the computer so can’t check).

I dragged my feet for a long time before switching from chrome to firefox a year or two ago for that exact reason. When I actually did switch it was practically seamless, I haven’t run in to any website that has been problematic on firefox but not on chrome. The only thing i dislike is that i haven’t found a way to have a custom newtab-page but still be able to directly input text to the navbar, so i always have to do ctrl+t -> ctrl-a.
