Firefox (88.0 64bit up-to-date) on a company managed Win10 machine.
WebZ is not keeping information across Sessions, including Login.
This means every time a new tab is opened (even without Restart of the browser, even when WebZ is already opened and logged-in in another tab) WebZ would need a new login (both for Phone-Number and QR-code based - 2FA is enabled for my account), even when "Keep my signed in" is checked.
Also changing the background image is not persisted and resets back to the default. I haven't tried other changes yet.
Steps to reproduce
Open webz.telegram.org with Firefox/Win10
Log in, do check "keep me signed in"
optionally change the background image
Optionally close the tab.
Optionally close the browser.
Open webz.telegram.org again -> login is gone, need to login again
Log in -> background image is back to default
It may be - I am only just not able to login on WebZ. When I enter my mobile number it's either 'Unexpected Error', or it keeps loading forever saying 'Please wait', before it finally goes into 'Unexpected Error' again. At the same time, a login code is being generated. This is what the Console is giving me in Firefox: Error: Promised response from onMessage listener went out of scope 7 common.js:4:491 [2021-06-13T17:12:38.364Z] [WARN] - [Connection closed while receiving data] 6b9e1c477ee38548ce72.worker.js:2:186420 [2021-06-13T17:12:38.977Z] [ERROR] - [WebSocket connection failed attempt: 1] 6b9e1c477ee38548ce72.worker.js:2:186420

PS: The first one seems to come from an extension here, so you might ignore it (common.js).
Took a few attempts to finally log in. Now it is still a bit wonky. Dark Mode won't save, and upon reload, I cannot click any conversations in the left panel, and clicking Night Mode in the settings will also produce a dark sidebar, but nothing more, until I click it again. WebK is very much stable though, so I stuck to that in the last few weeks..
