Why does my typing get delayed sometimes on my browser?

Maybe this will help you.

Off hand I would say you need more ram. I suffer from this at times and when it does it I notice my CPU is working at 30% or more capacity. I know it is because I need more ram. When I have too many windows open, or too many processes going it ties up too much ram and simple functions like typing either online or in Office, the computer has trouble keeping up. Second is that your CPU is old, which I doubt, and running too slow because of narrow bandwidth.

I find that that happens when my anti-malware stuff is doing a background scan, I am downloading stuff in the background, or otherwise has things going on that are taking CPU cycles. My laptop does it more than my desktop as it’s CPU is about ⅓ as powerful. Anything older than a Clarkdale Core i3 will have that issue quite a bit with any software written in the last couple of years.

RAM really isn’t an issue if you have 3GB or more; while Windows is a memory hog and Firefox isn’t exactly frugal either, 3GB is enough to run both comfortably and still have enough left over for other stuff like real-time virus protection.

Also, if any of your Firefox tabs have videos, you might be putting a little extra load on your CPU as it tries to decode them.

It happens to me in FF when other background operations are in process. I switch to Chrome and typing shows up right away. I’m guessing it is because I have so many add-ons on Firefox.

The NSA needs to make sure it’s you before it begins to capture your keystrokes.

Seriously, it’s general slowness combined with whatever stuff the browser is running. If the browser is running javaScript, or Ajax, then it is probably processing each letter as you enter it. That’s different from you entering a whole field and then <submit>.

Si the real answer is “it depends”.

For things like this I would suggest starting Firefox with no extensions and seeing if the problem persists. If it goes away re-enable one at a time until the problem shows back up.

Also any add-ons. My mom seems to get constantly infected with nasties from sites that want her to install shit to watch videos. Every single time it installed a add-on that fucked her browser. If you can watch Youtube you have what installed to watch videos on the Internet. Nothing else is needed that can be installed.

I know about Silverlight but that is pretty much dead now.

Firebug is a bottleneck when installed on Firefox. It’s a fabulous tool for a web developer, but it is doing a huge amount of client-side processing. If you have it installed and aren’t going to be using it, turn it off.
