PowerFox Web Browser - A brand new browser for PowerPC (Beta)

[Jazzzny]

I'm very happy to announce that I have implemented a font loading fallback utilizing FreeType for <10.6 builds of PowerFox!

Long time PPC users may know that TenFourFox historically struggled to load certain fonts, resulting in broken pages with a bunch of blocked A characters. This led to the font blocklist being implemented, which just avoided loading the problematic fonts.

However, for the first time ever, I have implemented a fallback layer to parse these rejected fonts with a different library, which resolves essentially every single font issue on 10.3-10.5!

I think G4/G4e versions will help the most people, and maybe cutting off G3 support on this Panther version as the weight of the UXP engine/modern browser is too much for them. To make a usable G3 version would be an impossible task, simply due to the G3 itself. And G5 users are better off on Tiger/Leopard.

Me too would prefer a G4 OSX 10.3 version if i have to choose.

Hello all, as I prepare for the initial 10.3 Panther release of PowerFox, I would like your thoughts on which builds should be provided.

All possible configurations are:
10.3 G3
10.3 G4 7400
10.3 G4 7450
10.3 G5

The G3 version should run on all processors. That woud be the easiest solution to cover Panther with basic functionality, albeit without Altivec or other processor specific optimizations.

Speaking from TenFourFox downloads, the 7450 was usually the most downloaded version, closely followed by G5. 7400 and G3 were usually behind by an order of magnitude.

I'm so confused about how YouTube works on some machines/installations and not others... on the latest PowerFox (tiger) update with JIT and the one before, YouTube broke on all my machines (and V3 and h.264ify made no difference), the videos and the ads all play for a few seconds then the stream reloads and starts at 0. It does this a few times before it throws a "video can't be played" error... others have mentioned similar things here, is there anything you're doing different here?

You might want to start troubleshooting by testing YouTube with a completely new user profile (type about:profiles in the URL bar to create one), with no add-ons and no modified preferences. Use a direct video link such as this one that's known to play using H.264 instead of VP9 by default in supported browsers. If the Unresponsive Script dialog pops up, click 'don't ask me again', then 'Continue'.

Youtube videos per se generally play fine in PowerFox due to H.264 support in the browser if you choose a resonable resolution, but the web interface is a desaster. It does load, but very slowly even on a G4 1.67 GHz. The JIT doesn't make much of a difference in this case (but it does in others). Vorapis doesn't work for me, either. The old YT interface is quicker, but video doesn't play at all.

That said, I don't really understand why people would use a PPC Mac to watch YouTube when literally anything else you have in your household including your phone and every Mac built in the past 20 years does it better and quicker.

We like to watch videos on it for the novelty and to PROVE it can be done. Also videos look great, even at lower resolutions, on the eMacs CRT display.

Thanks for the tips, I may try it out. Although at this point I'd much rather wait to get PowerVLC or a capable streaming media player to bypass the horrible bloat of YT.

Same reason anyone is still doing anything on these old machines. For fun. I find it incredible that machines old enough to drink still have just enough raw grunt to achieve modern quality anything quite frankly. Does it heat the room doing it? Absolutely but that doesn't matter at this point. It's not like I'm going to be using any of my vintage macs daily at this point. Think about the machines that came out 21 years before my G5 Quad. The Macintosh 512 was high end. Windows wasn't even a product. Yet 21 years after the G5 Quad was released to be the crescendo of consumer PowerPC and it still can do some daily work. Pretty special in my mind.

It's not like I'm going to be using any of my vintage macs daily at this point.

Funnily enough I'm the one who still uses a 10.5 17-inch G4 PowerBook as a daily driver since I don't like the newer versions of Mac OS. (I do have a 13-inch MacBook Pro running Big Sur for some stuff the PowerBook can't do like synching my iPhone, but that OS is awful.) I was actively involved in maintaining TenFourFox from the beginning until its demise, and today am most delighted to see PaleMoon/WhiteStar, Basilisk PPC and most importantly PowerFox – they keep my 21 year-old computer relevant. But for watching YouTube on the couch I really just use my phone.

I absolutely agree - however with the right tools ie Python, yt-dlp and Mplayer, playing Youtube on my G4 iMac requires much less grunt than browsing websites.

I can 100% understand not liking the newer versions. Everything after Catalina is a massive mess (and Catalina isn't great to begin with) and the continuing dumbing down and iOS-ification is slowly killing my liking of MacOS. I finally had to upgrade to Sequoia due to everyone and their brother using stupid chromium web apps that artificially limit the OS version. Otherwise my 2019 MacBook Pro would still be on Catalina.

I've also been tempted to use my DLSD for more than a few party tricks every now and then. It still gets 2+ hours on a charge and is practically flawless. Just such a wonderful machine to interact with.

...
Interestingly, the Tiger build seems to struggle more than the Leopard build.
...

This is also my impression on both, Intel and PowerPC. I think, Tiger is just for nostalgic, but compared to Leopard it actually is a bad operating system. On the other hand it is of course less hungry for resources and has the nice pine stripes.

Anyway, some glitches: the keystrokes for "Adress Bar" (Cmd+L) and "Reload" (Cmd+R) are still not working on PowerFox Tiger (PPC + i386).

By the nature of Mac OS X 10.4 and 10.5, my very own Homepage makes Powerfox glitch, when hardware-acceleration is enabled. On Snow Leopard everything looks fine. As I like to support older devices, I might change some effects on my Homepage, but honestly I don't know what exactly causes the glitch ... in fact, all my effects used to be supported by Powerfox just fine. But as I said, Powerfox is not to blame here, and without hardware-acceleration, everything looks fine.

Is there any chance to see PowerFoxBox this year?

This has been resolved in the upcoming release, it was not caught during my testing.

I can reproduce the behaviour mentioned, however I would say it is quite a minor annoyance as scrolling causes content to render fine. However, I will investigate this when I have the time. Recent releases have had major underlying changes to the graphics code which improves performance in all circumstances but may have introduced regressions that I am unaware of.

Is there any chance to see PowerFoxBox this year?

Yes, however I wish to complete some much more important tasks related to the browser first. Software similar to TenFourFoxBox will be written but I am waiting for some time to make it a lot more functional.

I have been testing PowerFox 26.3 on Mac OS X 10.5.8 and Wayfarer 11.5 on MorphOS 3.20 and get some interesting results in the Octane benchmark, especially on the zlib test.
The PowerFox test is on a PowerBook G4 1,5Ghz and the Wayfarer test is on a PowerBook G4 1Ghz, but still some tests are faster on the slower machine! But the zlib test is the most surprising one (at least for me) not just in points but in time as well, on PowerFox the zlib test takes at least five minutes (on the faster machine) if not more, but in Wayfarer that test takes at most two minutes and that is on the slower machine!
My 1Ghz PBG4 gets about 950 with PowerFox, don't have MorphOS on the 1,5Ghz PBG4, so don't know what the score would be.
Not sure if the browsers run the tests the same or what makes the difference, but I thought I'd report it anyway.

 

[Jazzzny]

But the zlib test is the most surprising one

That zlib test uses Asm.js, which is a defunct web standard that can optionally be compiled to native machine code. PowerFox does not have an implementation for this, and as such, runs it through regular JIT JS paths instead. I do not believe that implementing the Asm.js compiler would be a valuable use of time, as again, it is an obsolete standard that is no longer used by any remotely modern website. Not even modern Firefox ships an Asm.js compiler anymore.

 

[PBobbenB]

Ok, I did not know that, thanks for the explanation.

Any idea why the Splay test gets double the score, is that also running some obsolete or soon to be obsolete code?

 

[Jazzzny]

Splay is dependent on system APIs that are rather slow on PPC Mac OS X, however I’ve implemented improvements for the next release.

 

[PBobbenB]

Great, thanks!

Never been happier to see a captcha (guess what I failed it) 🤣. Thanks for the intel build, running on MacPro 1,1 and C2D Macbook

Is there way to build 64-bit powerfox for G5 ? I think it runs out of virtual memory while trying to browse 'normal' (bloated) reddit.com .... Virtual memory column in Activity Monitor climbs to 3.0+ Gb and then crash.

If you do get it to build 64bit, tiger server on G5s can run ppc64 (retail can’t until leopard)

It is impossible to build a 64-bit PPC PowerFox, as the JIT is fundamentally 32-bit. I suspect that your crash is not actually related to memory usage, as I have found a few crashes in the JIT that will be addressed in the next release. Logs would be useful to confirm this.

I suspect that your crash is not actually related to memory usage, as I have found a few crashes in the JIT that will be addressed in the next release.

In TenFourFox the ION JIT sometimes needed a very large amount of stack space to do its thing, so in some situations the browser would crash when it ran out of stack. It's always something to keep in mind when working with this JIT.

I have ensured that PowerFox has the same amount of stack that TenFourFox has. While I can increase this by a bit before colliding with other memory regions, I believe that it is adequate.

I can't get uBlock origin from the addons page to run at all. It not working means I am unable to load several sites like macrumors due to the google ad scripts hanging.

I should note that the same extension works fine on InterwebPPC and it works fine on Pale Moon on a Windows 7 laptop. I'm pretty sure it also worked fine on the 26.2.1 build, but on 26.3.0 it isnt at all. It seems to be an issue with it not applying out of date filters and being completely unable to fetch new filter lists
