Works OK most of the time, but the connection just dies occasionally requiring switching to a different server. This can result in multiple active logins (ie Facebook). Desperately needs a kill-switch feature to block traffic when the VPN proxy server connection fails. Also needs an option to autostart the VPN with the browser startup.
Over-all it does what I need, but plenty of room for improved reliability and features.

It seems that installing this plugin (not enabling VPN connection) is enough to break some websites login functionality. For example "Bad Request, The referrer header is missing." would be produced on https://accounts.fedoraproject.org/ while trying to login (reminder VPN connection itself is not enabled). Disabling the plugin resolves problem.

Like others, the last month with the PIA extension has been problematic. However, for me at least, using version 2.4.3 is working without obvious errors.

It is fixed for v71 for normal browsing but not working for private browsing along with many other regressions.

It's an OK, add-on. It has some basic flaws that prevent me from wanting to use it. Whenever you setup a bypass rules in the settings for a certain site, you need to restart the browser before it takes affect. Also, it seems to get different servers than the desktop version of the app. Sometimes with different speeds. Also the app forces you to choose custom "content blocking" within Firefox's settings; rather than allowing you to choose something else.
If the devs can make it quicker to adjust to bypass rules in the settings, I would definitely be willing to change the review.

不适合

It works fine but the bypass rules are not working well. The only reason I opted to try this addon is because it offers per domain bypass that the VPN apps don't allow. Problem is Amazon still think I'm behind a vpn even when on the bypass list and I can't watch Prime video. I've tried everything but still can't watch Prime video without turning off the VPN manually, which defeats the purpose of this add-on frankly.

I use pfSense with PIA, so I'm already running though the PIA VPN. How do I use this add-on w/o duplicating the VPN connection? I just want to use the added services, not the VPN itself. Is that possible?? Without that ability, it's wortheless. I'll find other add-ons to provide the same functions.

Nice to see the extension come to firefox. However, login data fails to persist between browser restarts where "privacy.clearOnShutdown.history=true". Unlike chrome version -- this necessitates re-entering username & password on every restart.
