My wife had been complaining about how slow Firefox was on her Lenovo laptop. I had experienced the same problem on my Lenovo and had made the switch to SeaMonkey. Yesterday I finally took the time to check her laptop out. It wasn't just slow. It was excruciatingly slow. Moving the mouse cursor over an item took 2 - 3 seconds for it to highlight, then took another 2 - 3 seconds to respond after clicking. Loading web pages was also unbearably slow. So I went ahead and installed SeaMonkey. Guys, it was the difference between night and day. I can't fully explain just how much faster SeaMonkey is on that laptop. I'm not promoting SeaMonkey here. I'm trying to point out that there is some problem with Firefox. I don't know if it's something that is only apparent with Lenovo laptops, certain video cards, just the configuration of my Lenovos, or what. What I can say is that if you are running Firefox and it seems slow to you, you might want to consider installing a different web browser. If you happen to really Firefox, but think it's too slow, you can install SeaMonkey, then add the Sea Fox extension and the Classic Firefox Theme For SeaMonkey extension and you'll end up with basically Firefox. No, there are a few differences, but basic layout and functions are close to the same.
I've been using seamonkey myself for years. Firefox is not slow on my I5 , 12 gig of ram Lenovo. You might wanna post
on both of your lenovos in this thread as a info share for others to respond to this thread.
Sounds like CPU is being hammered for what ever reason ON your lenovos.
IN terminal.
would give some info on my statement above. Only gear I have where blink based. And Firefox crawl on. Are my single atom netbooks and my Pentium 3 IBM T23 with a savage graphics chip. I run thge open source driver vesa on the T23. Newer xorg release and savage, openchrome, and sis linux drivers did not play well together back when I installed AntiX on it.
The story on those drivers may be different now < with xorg > . But I don't care and can live on how I have my gear set up.
Just for grins

I too am a big fan of Seamonkey. I think I've said so before on these forums, but Seamonkey has thousands fewer lines of code than Firefox, yet it has replaced both Firefox and Thunderbird on my computer. It's speedy and nimble and full-featured.
A lot of us are doing tests on the Beta of Linux Lite 3.6. So to be fair I'm using Firefox, because it's a default program & that's what ya gotta use for testing beta's. On a fresh install of Linux Lite uninstalling Firefox & installing another web browser is one of the first things I do. But along with my HP & Acer NVidia, I was testing LL 3.6 on an Acer Aspire netbook. It worked quite well for a netbook. . . except Firefox. I just couldn't take it anymore & wiped the drive, & put on Fatdog64 until the release candidate of LL comes out at the end of the month. What's sad is that Firefox used to be so good.
I'm using the 57.0a1 nightly now and it is snappier. May not make much of a difference to those on slower machines, but it would be interesting to see how it performs for you.
Hey, Jerry. I don't consider my laptops to be slow machines. You can check the hardware on this machine below. I realize that older, slower PCs can't run a lot of Linux distros and/or apps successfully, but I certainly wouldn't think either of my laptops fit that description quite yet. Maybe one of you guys sees a problem with my hardware configuration that would explain Firefox running so slowly.
