Q206: Tampermonkey tells me that my browser profile is broken. What does that mean?

A206 If your Chrome browser profile has a corrupted extension storage, you can try the following steps to repair it:

First, back up your browser profile folder. Q205 explains how to access it.
Then open Google Chrome and click on the "More" icon (the three dots) in the top-right corner of the window. From the menu, select "More tools" and then click on "Extensions".
On the Extensions page, click on the "Remove" button next to the name of each extension that you want to remove. This will remove the extension and its data from your browser.
Once you have removed all the extensions that you want to delete, close the Chrome browser and restart your computer.
After restarting your computer, open the Chrome browser again and go to the Extensions page. Re-install any extensions that you removed in step 2.
If the problem persists, you can try creating a new Chrome profile. To do this, click on the "More" icon in the top-right corner of the window and select "Settings". On the Settings page, scroll down to the bottom and click on "Advanced".
In the "Advanced" section, click on the "People" section and then click on "Add person". Follow the prompts to create a new user profile in Chrome.
Once the new profile has been created, you can install your extensions and try using them again. This should fix any problems with corrupted extension storage in your original profile.
