Use Firefox Aurora on your PPC. AuroraFox is designed to offer the best version possible to Firefox users that still use Mac OS X 10.5 on PowerPC Macintoshes. AuroraFox is using the code base released by Mozilla on the Aurora channel but also includes some elements from the TenFourFox build, such as the PowerPC method JIT, the Altivec/VMX accelerated code paths and the build support for Mac OS X PPC.

With all the PowerPC and Universal software quickly fading away it's hard not to get discouraged about the fate of the PowerPC Mac. The biggest thought is, what will happen to web browsing?
Well here is a small list of some web browsers I know of that still happen to work on PPC and many are still new enough to render webpages perfectly. In order of which one I prefer to the least (After #10 of Mac OS X the order doesn't matter I'm just listing them): Mac OS X 1. SeaMonkey 2.11 - Since the browser had dropped PowerPC support a while ago, another developer has picked up the project and is now bringing the browser back to the Mac. Features include: Hardware acceleration, Firefox addons, Cocoa GUI, Mail, Address Book, IRC chat. I personally prefer this as it loads pages with the speed of Safari but with the added hardware acceleration many things online run better. Requires Leopard.
TenFourFox 10.0.x - Another browser based around FireFox and brought back to PowerPC Mac's by way of a third party developer. It is essentially just a renamed FireFox recompiled on PowerPC (it's not universal so Intel Mac's can't run it, mwahaha.).
You also get the hardware acceleration and addons (I've found most work), but to me it's kind of ugly. It doesn't use the native GUI and to make it more 'cross-platform' between Tiger and Leopard it has a fairly ugly default interface. There are four builds of this, each optimized to a specific PowerPC processor. There's one for the G3, two for the G4 (old G4 and the G4+ which basically means any Mac newer than 2000) and one for the G5. Choosing the right one is somewhat important as each build is optimized for each specific PPC cpu. For instance, the G4+ has the AltiVec Velocity Engine which when used by the browser, means you get much better Flash performance overall. AuroraFox 16 - Yes I realize this is ANOTHER FireFox browser but I want you guys to have the ability to make decisions about your PPC Mac software (haven't had that feeling in a while have you?).
It's the FireFox beta build and it was released at random for PPC. File converter for mac. Features include. Look it up, it's FireFox. WebKit - This may sound odd but you can download a nightly build of just plain ol' WebKit.
This is what you need if you absolutely prefer Safari to any other browser as WebKit uses the Safari browser. This means you will have the latest in web rendering but can also use Apple's own software. Camino - Yet another rebuilding of FireFox, this one introduces a native Cocoa GUI, no FireFox addon support or hardware acceleration but has AdBlock built-in.

Nothing very special about this browser honestly. OmniWeb - WebKit runs under the hood of this browser with native Ad Blocking and an interesting layout. One of the first web browsers I've found that has the tabs located in an OS X Drawer rather than being in a bar. Not to mention it opens and quits with the same speed as Safari. Definitely worth checking out if not just for the novelty. This is universal and has been updated to work on Mountain Lion. Opera - I used to love Opera on my phone, on Linux, on Windows and even on Mac.

Until I realized how unreliable it is. If you love Opera and don't do anything too important on the web (like typing documents online), then download the last PowerPC version of Opera. Sadly it will crash at random after any length of time. Oh and that whole 'click to activate flash' thing is annoying. It's not like Click-To-Flash, it means that Opera loads Flash objects like YouTube videos, but you can't interact with them until you click on them.
HEIC, also known as High Efficiency Image Format (.HEIF), is a new space-saving image file format introduced by Apple with iOS 11 and macOS High Sierra. Thanks to the fresh HEIC format, we can now store more photos in high quality on iDevices. However, it's not yet supported by most image editors, meaning we can't share and view HEIC photos on some older iOS and Windows versions. That's why Joyoshare HEIC Converter for Windows comes with the purpose of solving all compatibility issues linked with HEIC images. With Joyoshare, you can easily convert iOS 11 HEIF (HEIC) pictures to JPEG, and other more popular photo formats without any quality loss. 
So if your video starts playing and you don't want it to, you have to click, wait a second (because double clicking would go full screen), and click again. This browser does support addons but I haven't been able to find any that work with this build anymore as you need Opera 11 or higher which is Intel only. Shiira 2.3 - Another browser brought to you from Japan that uses KHTML (also known as Apple's WebKit) and has been written in Cocoa so it fits your Mac's GUI nicely. I didn't get much time to play around with this browser as Safari always ran better for me, but it's worth looking at for it's relatively small size. It opens and quits on a dime but seems to render pages like an old browser would. It also has like OmniWeb, and interesting tab bar which you can see on the bottom. ICab 5.0.1 - Another web browser to use WebKit, iCab is a browser developed by a single man for the Macintosh.
