With an adblocker, sites load faster, but some still take fucking forever.

I also remember one airline company's site used to work perfectly and was very quick back in 2010-17. One of the more recent "updates" was seemingly to make it stop working on desktop browsers - no, seriously, when trying to buy seats on a desktop browser, the fucking thing will fucking crash when it reaches the "choose your seat" page. My dad complained about it ~2 years ago. Of course the company didn't do shit, as I recently found out firsthand.
