It seems like there was yet another performance update.
The homepage loads in less than 20s, and it's really snappy once it has completed loading.
Threads now take ~30s to load, and still occasionally freezes Android, but the load times are definitely better, including scrolling.
I didn't change anything on my phone, except it dropped from 55% to 21%.
One thing I noticed though is that the amount of lag seems to vary by the time of day.
Looking at adblock seems to indicate that it might be the ad network(s) causing the lag.
And speaking of ad network, it seems like ad serving is slightly less aggressive at early morning my time compared to late night my time.
At night the amount of blocked ads is rapidly climbing, whereas at the time of writing at early morning, it has given up after a few tries, and the website is actually usable performance-wise!
And while writing this reply, I noticed an issue where the editor keeps randomly scrolling behind the touch keyboard, which is quite annoying, as I have to scroll the text back out from under the keyboard to be able to see what I'm typing.
Pretty sure it did work properly in XF1, and that Firefox's attempt to position the textbox just above the keyboard has never failed me before, so I have a feeling it's a script doing it.
Looking at the URL, I think it tries to keep me scrolled to the post which I opened through notifications, but it keeps re-triggering both randomly, and also on editor focus change.
