[SOLVED] Protonmail overloading Pale Moon and the system

Post by ron_1 » 2026-06-12, 20:44

Operating system: PCLinuxOS-Debian Edition
Browser version: 34.3.0.1 (Linux GTK2)
32-bit or 64-bit browser?: 64-bit
Problem URL: Protonmail once logged in

Starting today, Protonmail borks Pale Moon and the whole system slows to a crawl. While the login page loads fine, the mess starts once logged in. I can't report it to them because the page never loads properly, and I have to kill the Pale Moon process. Can someone who uses Protonmail check it out? It loads fine in Chromium, but I want to see if any other Pale Moon user has the same problem before I report it to them.

My link leads directly to my inbox, and it seemed to work just fine once logged in. Also went to All Mail and proceeded to press Include Spam, and scrolled down. Worked like normal here.

Okay, then I have no idea how to troubleshoot this. Protonmail is the only website that does this.

No such problems here. Did you try it in a clean new profile?

Protonmail requires hardware acceleration turned on, which I either forgot or didn't know. Sorry for the false alarm.

IIRC hardware acceleration is disabled by default in the Linux version of Pale Moon, so it's not surprising that you just found out it's turned off. I think you should still report it to Proton though; I don't think it should be normal for a webmail to use up a lot of resources for (I presume) rendering. What GPU is your system using?

I experienced these exact symptoms the first time I tried to log in to protonmail after updating to PM 34.3.0.1. When I clicked the 'X' to close the tab, it took about 3 minutes for the system to respond, but once the tab closed, everything went back to normal.

Now here's the really odd thing: I have two protonmail accounts. When I log in to one of those accounts everything works as it always has, but when I log in to the other account, I get the behavior ron_1 describes. (I tried this multiple times, clearing all cookies between log-ins, and got the same results each time.)

The only difference I can see between the two accounts is that the one that fails has a much longer user-name (18 characters), while the account that works as ever has only 6 characters in the log-in user-name.

It seems unlikely that the length of the name is the culprit, but, like I said, it's the only difference I can see between the two accounts....

(I'm skeptical of the HW acceleration explanation, only because none of my settings have changed, and I was testing these two accounts without changing anything between log-ins. Yet, consistently, one account works like always and the other locks up the whole system as soon as I click the button to sign in. Very bizarre.)
