I work at a power plant which requires staffing 24/7. We have rotating 12 hour shifts, so nights and weekends are standard. It's very busy sometimes, but if things are going smoothly we get some downtime. I taught a couple coworkers how to add YouTube AdBlock to their browsers at their workstation computers. Now they're more efficient in their loafing on the clock.
For those who want to know, just search for the extension web store for your browser and search “YouTube AdBlock”. Check for both high rating and high quantity of reviews. Add the extension that looks good, close your browser, open it back up, and if you want to get back where you were you can hit Ctrl+Shift+T to reopen closed tabs. The whole process takes under a minute.
Some of you may be thinking “cool, but IT blocks us from downloading stuff to try to prevent malware.” Well, that's the case here too. We're still able to add extensions to browsers, so give it a try!
Cheers, comrades!
