For example, this 14mb XML file:
https://epg.liveiptv.net/epg.xml

I couldn't even wait for Fx to display the content, fearing my PC would fail for lackign RAM. Memory usage grows in a order of multiple gbs, so I needed to close the tab.

What OS are you on? And how much memory are we talking about here?

Flags: needinfo?(tustamido)

Windows 10.

Before opening the URL, Nightly main process uses 162mb. Waited for the page to load, now it's using 2025mb. Closed the tab, dropped to 169mb.

Flags: needinfo?(tustamido)
Severity: -- → S2

It's a large file without styling so it's expected to see usage growth during opening.

Severity: S2 → S3

I believe this was fixed at some point. Tested now with a 21MB xml and memory just increased by ~100MB, incomparably less than 2GB for the 14mb file at the time I filled this bug.
