Firefox: 50 Slow Performing Add-ons

Updated 12. April 2011 - 2:38 by rhiannon

If you're thinking Firefox has become slow and sluggish these add-ons could be the culprit.
From the Mozilla Add-ons page:
"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."
Here's the current list of add-ons that can cause Firefox to slow down. They are listed in order, with worst products first. For actual numbers on the degree of performance degradation check the current bad boys list at Mozilla which is regularly updated. In the last 24 hours the list dropped from 50, then to 7, then to 6 add-ons.

• #1 Firebug
• #2 FoxLingo
• #3 FoxClocks
• #4 FoxyTunes
• #5 Video DownloadHelper
• #6 Xmarks Sync

One additional thing I've seen that can really slow Firefox down are Flash cookies. These cookies are persistent and use Adobe's Flash to store their data in browsers. Flash cookies aren't deleted when you delete cookies from Firefox (or other browsers for that matter). Firefox add-on Better Privacy can detect and delete these cookies in Firefox, but that leaves other browsers wide open.

Wow! This may be the answer to saving my beloved Firefox! I was just about to give up on here and try to start using Chrome. With all of the troubles I have been having with Flash slowing down Firefox. Bringing it to a complete halt. Sometimes even locking up my System and causing me to get tired of waiting and doing a hard shutdown and reboot. Check out my Article on this Flash Problem...  Flash App npviewer.bin Slowing Firefox and my Fedora 13 System Down Allot! Using 50 to 100% of CPU Resources! I had already figured out that some Firefox Addon's were causing it to slow down and lock up. Like Xmarks Sync and I disabled them for a few months and only enabled them when I wanted to Sync my Bookmarks. But they both got to where they wouldn't run at all. So, I uninstalled them both. I use to love Video DownloadHelper. But, after testing it out. I finally uninstalled it too. This is a very helpful Article.

Thanks!:)
