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.
