Slow browser loading Firefox

[gold_finger]

@letdowncrush,

When you had Win 10 on it, how was browser performance on youtube?  Any better than with LL?  Or about the same?

Generally speaking, most mainstream browsers (Firefox, Chrome, etc.) have grown "heavier" over the years, (mostly to accommodate the changing nature of web content that sites provide these days).  Unfortunately, that means for more sluggish performance when running them on older or underpowered systems -- particularly on sites that have flash content, or streaming videos.

I've got a Dell Latitude 2120 with the following specs:

It handles most things just fine, but when I play youtube videos in full-screen mode they are a little choppy and the CPU is close to maxed-out.  Not much I can do about that -- it is what it is.  If I'm just clicking around youtube watching short clips, I just don't do it in full screen.  CPU usage is still pretty high, but videos are not so choppy.  However, if I'm watching something longer (like a movie), I just stream it directly thru VLC and that works fine in full-screen mode and the CPU usage is around 60% instead of in the 90's.  You might want to try that for watching longer videos.

• Copy the url of the youtube page for the video
  
• Start VLC
  
• Go to Media -> Open Network Stream
  
• Paste the url into the address box
  
• Click "Play"
  

Also, browser addons like Adblock Plus and NoScript do help speed things up a bit by blocking a lot of the unnecessary clutter on various sites.  Adblock does its thing without you needing to interact with it.  However, NoScript will take some time to get used to if you're not familiar with it.
