There could be a few reasons why you are unable to install extensions in your Chrome browser. One possible reason is that your computer's administrator has set policies that prevent you from installing extensions. To check if this is the case, you can try the following steps:
- Open Chrome and type "chrome://policy" in the address bar and press Enter.
- Look for any policies that are related to extensions. If you see any policies that are set to "Disabled" or "Not set," then they may be preventing you from installing extensions.
- If you are on a work or school computer, contact your IT department to see if there are any policies that are preventing you from installing extensions.
Another possible reason is a corrupted chrome profile, you can try to create a new profile, that should fix the issue. To do this:
- Click on the three dots on the top right corner of your browser.
- Go to Settings
- Scroll down to the bottom and click on the "Advanced" button.
- In the "Users" section, click on "Add new user."
- Follow the prompts to create a new user profile.
- Log in to the new profile and try installing the extension again.
If none of these steps work, you may want to try reinstalling Chrome or checking if your computer is running any anti-virus or firewall software that may be blocking the installation of extensions.
It's worth noting that if you are still unable to install extensions after trying these steps, it's always good to check if there are any updates available for chrome and also check the chrome support site for more information
