But since you asked... there have been many times when I used my wipers thousands of times each day for several days on end. But we're experiencing a bit of a drought right now so I've not used them in a couple months.
Also, some things are kind of frustrating, but not frustrating enough to bother spending ages fixing it.
Quite often something will happen and I'll think "there must be a fix. I just don't know the OS enough yet" - and sometimes there is a really easy fix and sometimes there is an ugly 3rd party kludge. While the problem is kind of annoying having a fix just fixes the problem, while searching for a fix teaches me more. (Am I making any sense? Its about the journey not the destination).
I can't even imagine how that is useful. I guess it is to them or they wouldn't do it.
I tend to "open in new tab" and queue things for reading.
Because I tend to open lots of new tabs within a short period, it makes identifying the one that is playing sounds very hard. The worst is the "delayed video player" scenario, especially if it is below the fold. It's incredibly annoying and embarrassing to be desperately trying to find where the noise is coming from if it happens in a boring meeting.
On firefox is just Bookmarks > Bookmark All Tabs
