Adobe loads the said extension in all the browsers. There is an easy guide from Mozilla KB here on how to uninstall and remove persistent extensions manually.
Follow these steps:
- Menu > Help > Troubleshooting Information.
- Scroll to ‘Application Basics’ section and click on ‘Open Folder’.
- And in the folder, navigate to the extensions directory and delete the Adobe Acrobat extension (you should be able to identify it, but if you can’t, go back to the ‘Troubleshooting Information’ page and find the id in the ‘Extensions’ section).
