3Mozilla 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

1. Nokia’s PC Sync 2 Synchronisation

  • Click on start, and type regedit
  • Nav­ig­ate to [HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla\Firefox\Extensions]
  • Delete the key bkmrksync@nokia.com

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)

3. Sun’s Java Deploy­ment Toolkit 6

  • Delete C:\Windows\System32\npdeployJava1.dll

4. Adobe Acrobat — Cre­ate PDF

  • Click on start, and type regedit
  • Nav­ig­ate to [HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla\Firefox\Extensions]
  • Delete the string web2pdfextension@web2pdf.adobedotcom

5. Adobe Con­trib­ute Toolbar

  • Click on start, and type regedit
  • Nav­ig­ate to [HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla\Firefox\Extensions]
  • Delete the string {01A8CA0A-4C96-465b-A49B-65C46FAD54F9}

6. Adobe Acrobat

  • Browse to Pro­gram Files (usu­ally C:\Program Files (x86)\ or C:\Program Files\)
  • Open The Adobe folder
  • Open the Acrobat ##.# folder (where ##.# is a version)
  • Open the Acrobat folder
  • Delete the Browser folder

7. Adobe Flash Player 9 r45

  • Delete c:\windows\system32\NPSWF32.dll
  • Delete c:\windows\system32\NPSWF32_FlashUtil.exe

8. Win­amp Applic­a­tion Detector

  • Loc­ate the fire­fox install­a­tion folder (usu­ally C:\Program Files\Mozilla Fire­fox\ or C:\Program Files (x86)\Mozilla Firefox\)
  • Open the exten­sions subfolder
  • Delete the file npwachk.dll

9. HP Smart Web Printing

  • Delete the folder ‘MozillaAddOn3’ from C:\Program Files\HP\Digital Imaging\smart web printing

10. Skype Click to Call

  • First remove “skype click to call” from “pro­grams and fea­tures” in the con­trol panel. (Note: in Win­dows XP or older, ‘pro­grams and fea­tures’ was called ‘add/remove programs’)
  • 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
