Update 3 4/6/21 This addon breaks all the time and it takes months for pia to fix anything, it's mandatory to have 3 or more different back up browsers and 2 os, if you want any kind of usage out of pia's service. Don't bother asking for help on their reddit they delete posts to keep the negative pr at bay. quite often. For one of the most popular VPN services this one is a total miss.

does not work in FF 71

Worked for a while, but not with 71 (64Bit).

Doesent work with FF 71.0 64 bit
Have been working very good until now
so if no fiks soon maybe its time to change provider

Stopped working, and gave me the excuse I needed to get away from PIA. Jump onto the reddit forum and learn about who they have become, and how they now do business. They should not be trusted with your private data.

Doesn't work since a couple days ago. Fix it.

Worked until a couple of days ago, now it's actually causing problems with my browsing and had to be disabled.

Does not work on FF Developer Edition 71.0b9

Sadly this extension does not work in Firefox Developer mode. The bad thing about this is that it fails silently. It shows a green icon but the VPN is not connected. Even tough you think you're safe, you're not. I already contacted the support but they only told me to use the desktop app. I always loved the extension because it was very convenient always being in a VPN while browsing w/o having to configure anything.

Difficult to understand and use..Not user friendly

Doens't work and the customer service wont give an ETA for a fix.

On latest update, as soon as I open any private window it logs me off completely, I have to relogin to my paid pia user account to continue using it. Without private tabs it seems reliable enough, but any one single private tab - and it logs off. I've been paid user for more then a year now, but now I consider switching, since reliable vpn is required for my work.

UPDATE: The plugin has been completely unusable for several months now. The problem is that it constantly asks for your username and password, there is no way to save them, and entering them just results in another prompt.

It's working relatively well so far, but there are a couple problems:
1. We're forced to use Firefox's builtin tracking protection (privacy.trackingprotection.pbmode.enabled). I really dislike this, because I prefer to use PrivacyBadger to dynamically block trackers. This should be user-configurable.
2. I'm prompted to relogin every time I open a Private Window. I would much prefer for it to work seamlessly, remembering my credentials the way it normally does.

My experience with this . add-on is that it is unstable and unreliable. Tech support is trying very hard to help but we're getting nowhere.

not workin on turkya

Not working since update

The VPN randomly stops working and it doesn't matter which VPN source (Houston, Chicago, Denver, etc) it will just time out. Have to restart Firefox when that happens and it is very inconvenient and annoying when you have multiple tabs open.

I am unable to turn this off. When I try to turn it off, the icon spins forever. It is now always green and on.

I got a year of PIA earlier this year but had to get a different one because the desktop app does not log on. I hoped that this might work but it didn't either. PIA was recommended to me by others so I suppose it works for some but it has never worked for me.

Cannot be used because I'm on Firefox Legacy.
Why then, was I allowed to download, install it, and waste my time?

If you choose not to make it compatible with Firefox Legacy, then flag it as such in the Add-ons market so people don't waste their time.

I am not happy as this VPN service has affected my online banking access. I have received a notice form Microsoft Security to warn about unknown activity. I am still trying to access other issues that have been created by this specific VPN service. If their tech people in the next few days fail to sort out my issues I will cancel and demand a refund. They were rated high by PC Mag and while I read some negative comments about their service I went ahead with it due to the PC Mag rating. I should have paid attention to the negative comments which I might add also included comments about poor tech service. Additionally unlike other VPN services I have tried because they offered a free trial this one does not (Big mistake in my opinion on my part) Also now I have downloaded their system unlike other VPN services they do not provide a webpage logon to which I can go to find out possible solutions to my problems and as well how to temporarily log off their system, and in my view why? I also changed the settings on Google Chrome to both allow their system and to allow my speakers to work (another problem) and very apparently their Google Chrome extension is bogus as it did not change the problems

Firefox Add-on not working (Firefox 60.0.2 in Ubuntu 18.04).
You can enter your username, but field for password does not respond.
