True. And I can see that some webs gradually stop working if you are using JS blockers. For example Aliexpress used to work fine with uMatrix. Now, if I click on the Next page in the paginator, it behaves like it loaded the next page, jumps to top, but it didn't - it just changed URL location. So I have to CTRL+R to reload the whole page to force their server-side rendering. I know it is theoretically my problem but I have to use JS blocking to stop (for me useless) ads and malware scripts. If they just loaded content from their domain or sub-domains, it would work perfectly fine. And if it were old-school server-rendered website, it would probably work faster, as it was discussed here some time ago. I have a feeling that web devs are sometimes over-engineering it. Web browser is HTML viewer, not an operating system.
