How to Fix Adobe Acrobat Pro DC Firefox Add-On Reinstallation Problem
Question details
The user experiences recurring installation prompts for the Adobe Acrobat Pro DC extension in Firefox when moving a user profile across different Windows workstations.

- Product
- Adobe Acrobat Pro DC / Mozilla Firefox
- Device & OS
- Windows
- Scenario
- Using a roaming or shared Firefox profile across multiple Windows workstations that have different editions of Acrobat DC installed.
- Observed behavior
- Firefox detects a version mismatch and repeatedly requests the installation of the matching Acrobat extension for the local workstation's Acrobat DC edition.
Check and note down the exact version of Adobe Acrobat DC (e.g., 2015 Classic or Creative Cloud) currently installed on each of the affected Windows workstations.
Ensure Consistent Adobe Acrobat Versions Across Workstations
Since Firefox extensions are version-specific to the Acrobat DC edition, standardizing the installed Acrobat software across all your machines prevents extension conflicts.
Acrobat DC 2015 Classic and Acrobat DC from Creative Cloud use completely different Firefox add-ons. Whenever a synced Firefox profile is moved to a workstation with a different Acrobat edition, Firefox is forced to request the matching add-on, causing the recurring prompts.
Open the Control Panel on your Windows PC, go to 'Programs and Features', and check whether you are running Acrobat DC Classic or the Creative Cloud version.
Select the Acrobat version that does not match your primary workstation setup and click 'Uninstall'.
Download and install the same exact edition of Adobe Acrobat DC across all workstations so that Firefox relies on a single, consistent extension version.

Disable Extension Syncing in Firefox Profiles
If you cannot change the Acrobat versions on the workstations, disabling extension syncing will stop your Firefox profile from pushing incompatible add-ons across devices.
Read and Edit PDFs Directly with WPS Office
Avoid browser extension conflicts and recurring installation prompts by using WPS Office. Its built-in PDF tools allow you to view, edit, and convert PDF documents natively on any workstation without relying on third-party Firefox add-ons.
- 1. Install WPS Office: Download and install WPS Office on your Windows workstation to access its native document and PDF tools.
- 2. Open the PDF Tab: Launch WPS Office and click on the 'PDF' tab located on the home screen interface.
- 3. Load Your PDF File: Click 'Open' and select your PDF file from your local storage to load it directly into the native editor.
- 4. Edit Without Extensions: Use the comprehensive built-in toolbar to highlight text, add comments, or edit PDF content without needing Firefox add-ons.

Frequently Asked Questions
Why does Firefox keep asking me to reinstall the Adobe Acrobat add-on?
This happens when you use the same Firefox profile across multiple workstations that have different versions of Adobe Acrobat DC installed (such as Classic vs. Creative Cloud). Firefox detects the local version and tries to match the extension to it.
Are Firefox add-ons for Adobe Acrobat version-specific?
Yes. Acrobat DC 2015 Classic and Acrobat DC from Creative Cloud use completely different underlying Firefox add-ons. Switching between PCs with different installed versions forces Firefox to request the corresponding version.
Can I simply disable the Adobe Acrobat extension in Firefox?
Yes. You can type 'about:addons' in your Firefox address bar, locate the Adobe Acrobat extension, and toggle it off. This will stop the recurring installation prompts, though you will lose the browser integration features.
