Many open windows make Firefox very slow on fedora?

It can take as long as 20 seconds to scroll the screen, which tends to scroll in large jumps, even when smooth scroll is enabled. The problem is worse when smooth scrolling is enabled, but is bad enough even when it is not.

Other applications seem to have scrolling slowed somewhat when Firefox has many windows open. It looks to me like a memory swapping issue, but I have no evidence beyond my gut. Right now Firefox has 30 tabs open on all its windows. Performance is bad, though not intolerable.

Firefox looks like it has a memory leak.

A workaround for this is to periodically restart Firefox. You can configure Firefox to save your tabs and windows so that when you start it again, you can start where you left off. See Restore previous session - Configure when Firefox shows your most recent tabs and windows for details.

Restarting Firefox doesn't do any good, only reboot works. Once swap gets allocated by Firefox it never gets released back. Good solution I found is using Chromium instead - forget Firefox otherwise it kills your system resources.

Firefox is slow and reason is trackers & ghostery

In the past I used to think why Firefox can be slow when it's loading pages. Now I've found something that makes a noticeable difference: the addon "ghostery" that blocks "trackers," which their website defines as
page elements - scripts, pixels, iframes, etc. - that are normally invisible to the user. What "trackers" seem to be all about is marketing, and apparently they've been wasting a lot of my time.
http://www.ghostery.com

What's especially interesting to me is a list that shows the trackers that have been blocked for each website I visit. For example, the intro page for cnn.com includes 20 such unwanted visitors with names like "Audience Science," "Dynamic Science," and "Scorecard Research."

Favicon is not supported on Firefox?

Looks for firefox version (my current version is firefox-29.0-5.fc20.x86_64) favicons don't work. I'm sure that in some earlier firefox versions they were supported.

This issue seems to be distribution independent. Anyone has any idea?
