"Click to re-enable First Party Isolation" button does not re-enable FPI

[miiichael]

(I think this extension might be abandonware, but in case someone wants to pick it up...)

Steps to reproduce:

• install firefox-esr 128.9.0esr-2 on Debian trixie.
• install this extension, enable toolbar icon.
• (successfully) use icon to disable FPI on website using google logins.
• (unsuccessfully) use icon to re-enable FPI.

I was hoping the extension would avoid the need for me to go wading through about:config 😅

I can confirm that clicking the icon does not change privacy.firstparty.isolate from false.
