My Browser Builds (Part 4)

[UCyborg]

Recently checked that Skyrim Reddit page with the sky animation on upstream Pale Moon on a laptop with dual-core 1,35 GHz APU with Radeon R2, radical difference between HW acceleration (GPU) on and off. CPU was pretty much fully loaded with GPU acceleration off and I actually couldn't open menus below title bar (I use them of instead of "Pale Moon" button) besides responsiveness to scrolling being very bad. GPU acceleration enabled reduced CPU usage to little below 70% and the responsiveness was back to normal.

However, let's finish this off-topic - good to know the two protagonists of this thread are fine!

Yes, I agree: I am very glad to hear that both @VistaLover and @roytam1 are still fine! You know how much I am worried for them (especially roytam1, who never fails to impress us , and don't worry, you too VistaLover!)

GPU acceleration enabled reduced CPU usage to little below 70% and the responsiveness was back to normal.

Good to learn that GPU acceleration works, but "little below 70%" is still super high for something purely cosmetic! Luckily we now have:

pref: separated pref for long names of css animation/transition properties. (73a7ce1e57)

To clarify, the new prefs @roytam1 added are:

layout.css.animation-long-names.enabled
layout.css.transition-long-names.enabled

It appears these prefs are the equivalent of MCP's prefs (setting them false breaks MSFN), and the prefs with the original names:

layout.css.animation.enabled
layout.css.transition.enabled

... are @roytam1's from the 20230825 version of Serpent that have a narrower effect (MSFN basically OK).

So good work! Now we can have either, or neither, as preferred (which is what prefs are supposed to be)!

downstream should realize that I have consistently NOT been porting e10s related sec bugs since e10s is not supported by us. If they use e10s, they are missing a few hundred sec fixes. The vast majority of Mozilla's sec bugs are directly or indirectly related to e10s.

Although I'm not very concerned about the lack of sec fixes, for me the bigger concern is, as we go forward, further breakages like the one in the 20230902 build. Since e10s is a "relic" that hasn't been part of "official" UXP in ages, MCP obviously won't be testing their changes in that environment!

This time, it was easy to revert the change that broke e10s. Next time we might not be so lucky, and I'll have to start running the 64-bit version so I can have one gargantuan process....

Windows 95 runs idle loop when nothing is happening, so it's always 100% for purely nothing happening. MS-DOS didn't idle CPU either. Though back then CPUs were pretty slow as-is, I remember having to wait for a while for level to load in Hover! (the game that was on Windows 95 CD), today you see the loading progress bar for split second. Don't recall if I copied the game to HDD back then or always ran it from CD-ROM.

Back to that animation on Reddit, on my main quad-core PC (14 years old with 9 years old GPU), the CPU usage is only 8%. At least with HW accel enabled.

I don't like this concept of dividing 100% among CPU cores/threads, I saw in certain Linux programs monitoring CPU usage where 100% is one core fully loaded, 200% is 2 cores fully loaded etc. I think expressing it that way is more suitable for multi-core CPUs rather than cramming all cores in 100%.

There might be a lot of pixels to move in that case. With high density screens out there, perhaps it makes more sense to use higher rather than lower resolutions images. Though I don't have much experience with higher density computer screens, my old ones just keep working (14 years and 19 years).

Can I change the history size of visited addresses in New Moon? In number of items or how many days to keep it?

After Mozilla, in their infinite wisdom (), chose to make almost everything "async", user control over the length/size of saved history was removed in Fx-4.0+ ... E.g. read below:

https://support.mozilla.org/en-US/questions/864527

https://support.mozilla.org/en-US/questions/1059856

Thus, without an extension, you'd have to periodically purge older history entries inside Library yourself, i.e. manually ...

For NM27/28, there exists an "official" extension below: 

https://addons.palemoon.org/addon/expire-history-by-days/

Haven't tried it myself , you can test it in a copy of your NM profile...

PS: CAA holds a Fx-targeting version,

caa:addon/expire-history-by-days

(v1.3.0), which should be compatible with both St52/55; WE-format extensions recommended for Fx (that should work with St):

https://addons.mozilla.org/en-US/firefox/addon/expire-history-by-days/

https://addons.mozilla.org/en-US/firefox/addon/history-cleaner/

https://addons.mozilla.org/en-US/firefox/addon/historia/

(again, NOT tested by me in St52) ...

It does work with St; I use it myself. PM/NM will require the legacy version, of course.

Straw man! You know that's not the same thing. The idle loop is there because the CPU has to be doing something even when there's literally nothing to do, so the lowest-priority process is a simple loop that doesn't take cycles from anything else running.

Your Web browser isn't the lowest-priority process in the system! Even if animations are (hopefully) the lowest-priority task within the Web browser, they still take CPU cycles away from non-browser tasks. Your computer does more than just run a Web browser, right?

Chromium can get around that (don't know if it does, but it can) by creating a low-priority process for animations, but FF 52/53-based browsers like PM and@roytam1's are stuck. Even e10s doesn't create a separate, low-priority "animations" process.

To be fair, there are negative "side effects" from setting layout.css.animation.enabled to false, but they're mostly minor. Spinning "wheels of death" don't spin while you wait, for instance. I can live with that.

[UCyborg]

In any case, no one here is smart enough to optimize animations for ancient hardware. Maybe it's impossible.

Anyone here smart enough to figure out why images aren't shown in image posts on new Reddit?
