Add-ons can add functionality to your browser. Firefox has a lot of great add-ons that work well and don’t slow Firefox to a crawl. But there are others which can adversely affect Firefox’s performance – some can not only cause Firefox to run slower but take a lot longer for it to start up.
Without any add-ons, Firefox starts up in the blink of an eye. And if you’re careful, and choose your add-ons wisely, you can add features to Firefox without much impact on its performance.
We found this very interesting list on Mozilla’s (the company who makes Firefox) Website. We thought you’d find this interesting – especially if you’re a Firefox fan. But even if you don’t use Firefox, this will make you aware that add-ons can affect your browser’s performance, whether you use Internet Explorer, Chrome or another browser. You should pick your add-ons with care. If you notice your browser isn’t performing as it once did, the first thing you should do isn’t change browsers, but to check your add-ons. You can disable them one-by-one until you find the culprit(s).
Here’s the information from the Mozilla Website on add-ons known to slow Firefox. The first number is the general slowdown average across all operating systems. Since so many of you are not using Windows 7, we’ve included the figures for Windows 7 as well:
“Slow Performing Add-ons
Add-ons provide many useful features and functions, but they can also cause Firefox to become slower. Some add-ons can even slow Firefox to a crawl and make it difficult to use for regular web browsing. If you think add-ons might be the reason Firefox is lethargic, check the list below for some of the biggest bottlenecks. And remember, for best performance you should disable add-ons that you no longer use regularly.
