Don't know why there are so many negative reviews here. My PIA connection is neither 'broken' or unusable. My biggest gripe is the regularity of a proxy going offline while downloading, and I'll have to switch to another - irritating, but not a deal-breaker. And the reason it only gets 4-stars.

Can't get it to work in Firefox. Same error as all the other users

Edit: It finally seems to work again after 2 years!

Broken. Only gives the NS_ERROR_UNKNOWN_PROXY_HOST error.

Outdated and broken

Come on PIA guys, we use Firefox for a reason, and PIA for a reason. The add-on used to work well, but at the moment completely unusable with the NS_ERROR_UNKNOWN_PROXY_HOST error.

Dated application that doesn't work anymore. Choose a better VPN company to give your money to.

Stopped working within past week.

Paid subscription.

PIA FF extension v2.4.1.2
FF v108.0.1
Windows 10 Enterprise v19041.1415

doesnt work at all with paid subscription

This extension doesn't work on macOS Ventura with Firefox 108.

Private Internet Access it's a ridiculous company that doesn't know how to make an extension that works. I will cancel my subscription and never used them again. Time wasters that should not be allowed to do business on the Internet. Shame on you Private Internet Access.

Does not work.

Was previously an outdated version that didn't work, but they finally updated it now and it works.

Connection error
NS_ERROR_UNKNOWN_PROXY_HOST, how to get rid of it?

Does not work. Error "NS_ERROR_UNKNOWN_PROXY_HOST"

Connection error
NS_ERROR_UNKNOWN_PROXY_HOST

Just literally doesn't work. Shame on PIA for leaving this active and unusable. Take it down, or fix it.

Very disappointed. Whenever I try to enable this extension, and try to access any web site, I get the error:

Connection error
NS_ERROR_UNKNOWN_PROXY_HOST

All their support could tell me is "Unfortunately, we have limited support for the browser extension, and the only troubleshooting step for this is to reinstall the browser extension and use it with the Incognito/private browser". I replied asking what the "incognito/private browser" was, but haven't heard back. I don't know why they have this extension if they don't support it.

I'll try the Chrome extension in Brave, see if that works.

Recently stopped working, seems as if PIA have abandoned the extension altogether. Will likely have to cancel my subscription since I can't have my entire system routed through the VPN at times
