2Mozilla Firefox LogoRemoving Firefox plugins, addons & extensions

Nearly 18 months ago I wrote a brief note about how to remove cer­tain fire­fox plu­gins, addons and exten­sions which don’t have a “remove” but­ton in the Add-ons man­ager.  I have updated and added to the ori­gin­al list, and will con­tin­ue to add any fur­ther plu­gins I encounter here.  If in doubt there is usu­ally no harm done by leav­ing or remov­ing any plu­gins, addons or exten­sions.  I advise remov­ing all of those that you don’t use as they are using memory and pro­cessing resources and slow fire­fox down.  In some cases the sta­bil­ity of the browser can even be under­mined by plu­gins.

Note for 64bit Win­dows (with 32bit Fire­fox)
Instead of HKEY_LOCAL_MACHINE\SOFTWARE look in HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node
Also, instead of Pro­gram Files\Mozilla Fire­fox look in Pro­gram Files (x86)\Mozilla Fire­fox
Finally, instead of C:\Windows\System32 look in C:\Windows\SysWOW64

2. Sun’s Java Con­sole which is fre­quently lis­ted sev­er­al times with vari­ous ver­sions

  • Loc­ate the fire­fox install­a­tion folder (usu­ally C:\Program Files\Mozilla Fire­fox\ or C:\Program Files (x86)\Mozilla Fire­fox\)
  • Open the exten­sions sub­folder
  • Delete the folders named {CAFEEFAC-0016–0000-00**-ABCDEFFEDCBA} where the ** can be any num­ber (it appears to rep­res­ent the ver­sion num­ber)

  • Then delete the folder {82AF8DCA-6DE9-405D-BD5E-43525BDAD38A} from C:\Program Files\Mozilla Firefox\browser\extensions\

An addi­tion­al tip.  To loc­ate the rel­ev­ant files for each plu­gin do the fol­low­ing

  • Open the fire­fox help menu
  • Select troubleshoot­ing inform­a­tion
  • In the top box (Applic­a­tion Basics) click on the “Show Folder” but­ton. (Note: in older ver­sions of Fire­fox this was called “Open Con­tain­ing Folder”)
  • Open the file pluginreg.dat in a text edit­or
  • This file con­tains inform­a­tion about all the plu­gins, includ­ing their loc­a­tion.

The paths shown here are for 32-bit ver­sions of win­dows. FYI for the 64-bit ver­sions, the path looks like this:

HKEY_LOCAL_MACHINESOFTWAREWow6432NodeMozillaFirefoxExtensions

Just thought it was worth men­tion­ing since I could not find the registry keys men­tioned in this art­icle on my 64-bit machine.

Ah, yes. I updated the paths for files, but for­got to update the registry paths. Most of the info here is for either ver­sion, and I’ll update the reg keys. Cheers for the heads-up.
It will all change again when Fire­fox finally gets a prop­er x64 release towards the end of the year. Then I’ll have to update again
