My first 'real' server was a Dell PowerEdge 1850 that I got sometime in 2005. At the time it was a powerful machine with dual Intel Xeon CPU's each at 3 GHz, dual power supplies for redundancy, and U320 SCSI hostswap drives on a PERC 4e/Si. Years later I would later upgrade the RAM and storage to it's maximum capacity, but that can only take you so far.
Firefox for some time has been experimenting with something called DNS-over-HTTPS. It's a massive change to one of the most fundamental mechanics of the Internet and could have some seriously devastating effects. Since Firefox 74 it's enabled by default for new users, and since Firefox version 79 existing users that have up till now not enabled it are being asked to opt-in using a misleading popup.
If you use Firefox version 52 or later and you have Lenovo/IBM IMM firmware 1.47 and later you'll notice that there is no progress after pressing the Login button in IMM web interface. This the latest flaw in what was once a great browser. The people over at Mozilla think they know what's best and decide to break stuff in the name of 'security'.
