Stopped working for me either. I'm facing the same issue as some commenters below. When I click the icon it pops out a blank frame with a constantly spinning circle in it.

The free version keeps disconnecting after some time. I have to manually disable and re-enable the extension for it to work again.

Firefox 152.0.6 (aarch64)

Auto-connect doesn't really work after a cold boot or sleep. I'll get the notification that it connected, but the icon will appear as if there is no connection, and internet access is completely blocked. A few times of turning it off and on, closing and reopening Firefox, it will start to work again. I think it's related to auto-connect, maybe there needs to be a delay, but I don't really feel like troubleshooting. I really wanted to like it but the desktop app is just more reliable.

Linux Mint 22.3 - Firefox 152.0.5

The extension worked fine while on windows 11. But as soon as I switched to EndeavourOS, it just stopped. It fails to connect to servers, leaving me either with no internet on my browser, or to browse unprotected. This sucks even more because I'm a paying customer (unlimited).

Ive had no problems with this extension on other browsers like chrome and opera, but it simply refuses to work on firefox. It just keep trying to load for eternity without anything happening. The only other security/privacy add-on I have is UBO and my browser is up to date.

Works great until my laptop goes to sleep. Then it disconnects, and for some reason prevents Firefox from connecting to the internet at all. And since Firefox isn't connected to the internet, the extension doesn't load properly, so I can't even turn it off! I have disable the add-on to get Firefox to work, at which point I can reenable it and reconnect the proxy.

Doesn't work with Firefox Nightly, but does work with vanilla Firefox. Would be good if they can get it working with Nightly

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...

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.

The extension works fine, but suddenly it stops working; it says ‘network issue’ and I can't log out of my account or the VPN because the extension is somehow ‘frozen’ – I can't open the extension or its settings... Only by disabling the extension can I browse properly again.
I tried reinstalling the extension, but the same thing happened after a few minutes.



A temporary solution I’ve found is to disable the “connect automatically” option and to disable and re-enable the extension when it “freezes” and displays a connection error.

I love the service, but the extension is incredibly unreliable. Any time I try to set up a new connection, the entire browser locks up for tens of seconds. The connection drops off occasionally, to which the only fix is to disable then enable the extension, then wait for the browser to be responsive again.

it works well enough, when it feels like it. but god help you if you forget to turn it off before closing your browser! you'll be dealing with connectivity issues sometimes until and unless you restart the whole computer! it has a long way to go, but it has quite a bit of promise...

Requires disabling and re-enabling every time I launch Firefox or wake from sleep on OSX, which exposed my IP.

I have some minor problems with autoconnect borking out sometimes, but those are easy to fix. I mainly used proton to unblock netflix, but now it doesn't work with netflix, so I don't use it anymore. if it starts working again, I'll come back and rate it 4 stars

The inability to setup profiles, even as a paid subscriber, makes this far less useful than it should be. When you want to bypass your country's censorship the last thing you want is a default connection to servers in your country. Yes, you can manually change it, but this rather undercuts the purpose and convenience that auto-connect brings. Fastest connection to not my country is in the desktop app and I want to see it here too.

At least dozen of times literally, every week it freezes the connections and needs to be switched off. Sometimes it even needs the browser to be restarted. Encountered it already on the first day I started to use it, contacted CS, and learnt that everything was fine.
Other annoyances: requesting every few weeks to write a review.

I think a VPN extension only really needs ONE feature: quick-connect to a previously favorited country.

It is ridiculous that ProtonVPN does not have this.
I would take ANYTHING:
- A way to pin/favorite countries or servers
- A second button next to Connect that
- An option in the settings for what happens when I left click the extension
- create a hotkey to auto-connect to my favorites

I've only ever EVER used it to connect to a different country. But if I don't manually choose it in the list, then it will choose MINE. Why?! It's basically useless.

And I specifically only ever use Japan 99% of the time, and the US in the remaining 1%.
(I suspect a great majority of people use it similarly. Mostly one country.)

Both of which—because the list is in alphabetic order—I literally cannot even simply scroll down to!
Japan takes about 4 wheel turns, and the US takes 8.

So, evidently, I instead search for them. Just typing J or U is enough.
And THANKFULLY the search input is automatically focused. This is why the app gets 2 stars, not 1.

Great when it works. I constantly lose connection when trying to stream content on my browser. When I disconnect from the extension I have no connection issues. I have two server locations close to me and I try to switch when my connection slows down. But, this doesn't seem to help.

The free extension is frustrating, time consuming, does not choose the same country server as the PC installation & changes your PC local time to that of the server. Tech support wants pics & all the hairy details to solve simple, common problems. With every biz wanting fee for service, the public is getting nickled & dimed to death to give a CEO gas for their Bentley!

This extension can be good or useless.
the issue is it automatically connects you to a server, they say it use the fastest one but actually its random. for me for example netherland and romani servers works good but it auto connects me randomly to USA and Poland which do not work so i have to press the change btn a lot of times to randomly get netherland or romani. the system actually sucks it didnt used to be this way

電腦自休眠或睡眠喚醒後 chrome 版會自動重新連線，但 firefox 版只會是斷線而且連線狀態還顯示正常卻無法上網。

Seems that Proton is not checking their Proxy LetsEncrypt Certificates. Therefore those Proxies are no longer available. The Proton VPN Firefox Extension could do a self check and provide better user experience in these situations. Does Proton doesn't have an automatic Flow at their servers?

Запускается один раз, дальше просто скидывает и выдает ошибку.
