- A swap file or launching outside of xfce won't be useful.  I have hundreds of megabytes of memory remaining.
- Disabling images may help CPU usage.
- Ad-blocking won't matter.  I was originally doing basic testing with websites without ads.
	
		
	
	
		
		
			In Otter Browser..you must change the Appereance in the Settings and then you have Tabs visible
		
		
	 
Thank you.  I did this, and it worked.
Tools > Preferences > Advanced > Appearance > Widget Style: [Fusion]
However, I began examining CPU usage when waiting for tabs to load, and I don't see 100% usage.  So it feels like this is indeed a network issue.

I tried one USB stick but it failed to load.  I had a second which worked (I had to disable Wireless then disable and re-enable USB).
This makes a HUGE difference.
So to come back to the Pale Moon topic of this thread..
Pale Moon spikes to a very high CPU usage for some page loads, but it's minimal for a simple blog.  I tested my own: 
http://blog.spiralofhope.com and then 
https://blog.spiralofhope.com to see if SSL influenced things.  I could not see any difference.
I did load-testing with 
http://imgur.com
I don't know if everyday users know this, but the Pale Moon developer implemented a "superstop" feature which immediately disconnects a whole tab from every single network connection, including AJAX.  It is shift-escape.  On the Pandora, that is Shift-Fn-q .. it is VERY fast at stopping imgr long loads.
Some rudimentary testing with websites that use JavaScript seem to indicate Pale Moon's first-load of a heavily JavaScript-enhanced website is very very slow (CPU issue).  I tested with 
https://minds.com but I'll need to do more testing later.

I used htop (available as a PND) and configured it to show a column for I/O, and set up a graph for CPU usage.  This is how I could judge things better.  I should have been graphing network usage with another program, but I didn't think of that.
So my conclusion:  Pale Moon is fantastic.  However, I think there are some limitations with the network, because loading two tabs at once is poor.  This does not always max out the CPU, so I know it's a network issue.
I will have to judge other web browsers separately, configuring each to not use a cache so I can be fair with them.  Otter did seem quite nice at a glance, and so did some others.. but getting Pale Moon working is far more important to me, even if it turns out to be slower.

I also have a wired network dongle which I'd like to test.  It works on another Linux handheld (the Zaurus) but I have not tested it on the Pandora.

YouTube works.
(Overclocked to 969 MHz OPP3)
Fullscreen works.  A video must be paused to buffer for a while.
480p, 320p, 240p, 144p have good audio but choppy video.
Preferences > Advanced > "Hardware acceleration when available"
This is enabled by default.  Disabling allows 144p video to play quite smoothly.  Nothing higher quality plays video very well.
I don't know how to get rid of the bottom Loading message.  I believe this is straightforward, but I can't remember how right now.
Caching most of a 20:45 video in 240p works well.  I didn't even have 300 Mb of memory used, with spacefm and htop running with xfce.

Flash works. 
In about:config, set media.webm.enabled; false
The warning about the flash version being insecure can be ignored if you trust YouTube.
Fullscreen works.  I can get 144p.  The audio is perfect but the video is choppy.
