There are 2 online tools I find myself using quite often and whose, in my opinion, should be in any utility belt of any web-designer and web-master.
WebPagetest, a site where it test the load time of your page and analyzes what loads, how long it loads, and even gives suggestion on how to improve it.
And of course the most important one: Browsershots. Ever wondered how your website looks in Opera 8? Or IE 6? Or any other dozen browsers out there? You don't have to install 10 browsers to find it out. This webservice takes care of it for you by taking screenshots in each browser and uploading said screenshots upon completion.
Lately my video (HD) playbacks in YouTube seemed to be lagging a LOT! I wondered why. I thought it would be me and my years old OS or perhaps even somehow my pc.
But no it wasn't. The lag was caused by Firefox's session saving feature. A simple and fast change in it and "poof" went the lag.
- Open Firefox and type in "about:config" (without the ") in the Address Bar and hit Enter.
- Type in "session" in the "Filter" line at the top of the list.
- Find “browser.sessionstore.interval” and double click it. The 10000 milliseconds (equals 10 seconds) is the interval in which Firefox keeps saving your session in case of a crash; same amount of time between video lags.
- Change it to something different. 120000 equals 2 minutes, 300000 equals 5 minutes or something else you desire. I went with 600000 (10 minutes), because I don’t particularly care about session saving.
Recently I stumbled onto some tips how to speed up ones Firefox. Firefox, since the version 3, uses a SQLite database for various tasks such as storing bookmarks, histories, site specific preferences and backups.
Over time it's get filled up with unnecessary and old info if you want, and there's a simple method to ditch those useless info and speed up your Firefox considerably, or like most of the guides say to "vacuum" it.
Use it once in a while, I've seen an improvement on my Firefox since I used it.
- Go to "Tools" -> "Error Console"
- Paste this in the "Code" text box:
- Press enter or click "evaluate"
- Your Firefox will freeze for a short time, just wait
- Enjoy your speed up Firefox!
It never cases to amaze me how revealing and careless people are going on about on the internet. I mean nowadays where Key loggers, Worms, Virus and whatnot are as standard as your daily breakfast.
My dad, again for the umpteenth time, got infected with yet another Worm, this time it was, how could it be different, the Conficker. Of course he keeps his computer up-to-date, his Anti-Virus not so much. And on top of that he uses Internet Explorer.
Don't get me wrong, I did like the Internet Explorer once upon a time when I was just another kid starting out on the internet. Since then I went from Internet Explorer to Netscape, did a migration to Opera and finally found my home in Mozilla, later Firefox.
USE FIREFOX! Even though you have to get used to a totally different UI if you are switching from IE or Opera, it's well worth it in the long run. And here are 2 reasons why:
Of course there always IS and always WILL be a risk of catching a Virus, Key logger, Trojan. There's no 100% guarantee!
When I play WoW, I often surf the official boards. Occasionally there's some idiot posting Key logger links. By now the fear and paranoia on these boards have risen to such levels where people simply refuse to check out any links they don't know. A good idea indeed, but flawed nevertheless. Almost every link posted there contains useful information. Very, very rarely is it a key logger. Yet the damage of a few have jump started the fears of thousands.
I for one don't have to worry. I click any link I want and never catch anything. My NoScript blocks any script, by standard, unless I specifically allow them to run. Sure I have to spend a little extra time figuring out what this script is and what it does, but it's well worth the trade-off I get in security.
My AdBlock blocks ads, period. No Ads, I don't see any Ads, EVER. Not so long ago, there was a Key logger being distributed simply by an Ad-banner. I don't have to worry about it. Of course it must be said that some awesome and useful sites are financed purely through advertisement. It hurts them if you block all their ads!
I really do believe with the 5 tools mentioned above you are on the safest side possible without compromising too much.
So long, Don Salva
I've been getting e-mails with folks saying a firewall software is missing. I apologize. Let me clarify: If you have a modern hardware router there's no need for a software firewall as there already is one integrated in good, modern routers (I'm not talking about ancient ones, like from 1980 or so).
A firewall software is only necessary if you are paranoid and have the need of a illusory "double security" or if you have no router and are connecting direct to the internet via your personal computer with nothing in between your pc and the internet.
I was angry and frustrated that Firefox once again has slowed down the i-lost-count-this time! Seriously, it's such a great browser but so full of little problems which really can get annoying as hell!
So I went to google and found 5 easy-to-do tweak with remarkable results! Remarkable, because you truly can see the difference between a standard and a tweaked Firefox. One might wonder why such tweaks are not standard options..
Type “about:config” into the address bar and hit return. Look for the following entries:
- "network.http.pipelining" and set value to true
- "network.http.proxy.pipelining" and set value to true
- "network.http.pipelining.maxrequests" and set value to 30-40
- "nglayout.initialpaint.delay" and set value to 0
- "config.trim_on_minimize" and set value to true
If you don't have them, create them:
- Right click -> new -> boolean -> type in "network.http.pipelining" -> set value to true
- Right click -> new -> boolean -> type in "network.http.proxy.pipelining" -> set value to true
- Right click -> new -> boolean -> type in "config.trim_on_minimize" -> set value to true
- Right click -> new -> integer -> type in "network.http.pipelining.maxrequests" -> set value to 30 (default is 1)
- Right click -> new -> integer -> type in "nglayout.initialpaint.delay" -> set value to 0
Now the explanation as to what does what:
network.http.pipelining and network.http.proxy.pipelining:
It enables pipe-lining, which means the browser normally sends 1 request at a time, with pipeline enabled it will send the amount of request you set in "network.http.pipelining.maxrequests"!
Like I said Firefox usually sends 1 request at any time. By setting a different value than 1, you force Firefox to send more requests thus enabling it to load faster, because he gets more responses at any time.
Each time you minimize your Firefox it will clear the RAM. Firefox is infamous of wasting RAM for Pages you don't need so you can go "back" to them.
If this value doesn't exist or isn't set Firefox waits 250 milliseconds, or 0.25 of a second then starts rendering the requested page(s). People report that setting it to 0, ergo forcing Firefox to begin rendering immediately causes almost all pages to show up faster.
If you are one of the lazy lot, and don't want to manually tweak your Firefox, here's a great Extension with virtually the same effect
Enjoy your new, faster Firefox!
