Unable to connect to the internet after unlocking session on Linux.
Crash Firefox from time to time, which make a new session start without my tabs...

The bad thing about protonvpn free is that it assigns you a server based on your IP. Proton may be collaborating with authorities. Something we don't know internally, and they can already know your IP. So when you connect you are assigned to a free server but what you don't know who is connected to that server can be you alone or with other people. Another thing is that it uses VPS, dedicated servers are in England, we all know that England is an ally of the United States so draw your conclusions. What I don't understand is why one cannot choose which server to use and not that the system itself assigned me based on its preferences.

Great app, does a good job. I'd love it if they added a feature to turn on for specific websites.

So like sometimes I need to turn the extension on and off a lot sometimes cuz if I don't it just won't connect to internet. (The web browser not the computer) I've tried this on waterfox and librefox I believe and multiple devices and OSes

Works almost perfectly. A killp-switch would be necessary. Thanks Proton Team!

doesn't work it just makes my browser non functional, the app works fine though

I am very happy with the extension as it automatically connects without any problem. During my nearly 1 year use I never had a problem in any way.

It does its job. Reliable. Not greedy, the free version is quite good.
However, there are some problems specific to Firefox.
There are regular connection problems.
-It always says there's a problem connecting your account, but your account connects (this isn't a huge problem, it's just confusing for some).
-Sometimes it connects and then disconnects after a split second. You have to wait a bit. (Meh, okay, but it's still a problem)
-Sometimes it doesn't connect automatically (this is a minor issue if you've pinned it to the top right, but it's very annoying)
-Loses the browser permissions?? You have to delete the add-on regularly and re-grant the requested permissions. (This is what's frustrating because the necessity of this can be forgotten.)

At least I experience these problems in both Windows and Cachy.

I can't tell what's currently going on but starting since today I can't use the addon anymore. Every time I try to connect to a server the whole browser freezes and if I wait long enough, it crashes. I have to open Firefox in troubleshooting mode and remove the addon, because as soon as I enable it it tries to connect to a server and the browser freezes.

I used to love ProtonVPN extension. It was quick and easy. However, now it is a nightmare. It started with the last version causing issues where you had to disable it and reopen the browser, but only on Linux. Well now, even if you disable it, it will lock your browser up and refresh the page every 30 seconds, on Windows and Linux. You have to completely disable and remove it, then go into the folder and delete the xpi in order to use your Firefox. I spent hours trying to place the blame on anything else. Even doing the Firefox troubleshooting where it disables the extensions did not stop this problem. Only completely removing the xpi and setting for it would stop this. I don't know what is going on over there, but I'm sure that you all should revert some of the changes you have been making, since version 1.3.x, would fix these issues. The nag pop-up for rating is horrible, and it doesn't matter if we had rated it or not. There should be a leave me alone box.
Edited, for typos and clarity.

Update: Reinstalled 1.2.16 and the issues with the lockup and reload and forgot to add that just opening the browser without loading a page would cause it to just use up all RAM in the system over about a 5 to 10 minute window. You could just sit there and watch it keep climbing.
