Just two weeks in, we’re already huge fans of Firefox 4. It’s a noticeable improvement over the previous version in speed, design, and customisable options.But customising has its downside too. It’s no secret that loading your browser with add-ons can slow it down. Some add-ons are worse than others.

Mozilla has done everyone a favour by releasing a list of 10 add-ons that are known to significantly slow down Firefox 4 when it starts up.

We have the list here. If you think your browser is running slower than it should, make sure you’re not using one of these add-ons. They’re ranked one through 10 by how long they slow down Firefox’s startup, with number one being the slowest of them all.
