Hey there,

Firefox v78 is quite outdated and outside of our Browser support policy. Please try updating your browser and let us know if the issue persists.

Unfortunately I think that the issue affects modern browsers on moderns systems. However I was not able to reproduce it.

There also have been reports of this happening on Android

@Optomod could you please send us logs via settings -> about to hello@tutao.de after it happens? We are struggling to reproduce it. Thank you!

We've checked the code and it can't really happen in normal circumstances that click event handler fails. We suspect there is an uncaught error during the rendering pass and lifecycle methods are not actually called but we haven't seen any uncaught errors in the logs.

So far from the error reports we've noticed few cases:

• it is an old browser
• it is in multi search viewer or after it
• it is iOS 16.3

[charlag]

judging by #5214 this is what happens:

• some error in a lifecycle hook, most likely onupdate
• all errors are caught by mithril and logged, we don't get them in the error handler: https://github.com/MithrilJS/mithril.js/blob/88da9e56f92a4ee076a6a63ab7759fecb487e340/api/mount-redraw.js#L13
• except mithiril bind console super early, before we replace it

so the end result is that the whole class of issues is invisible to us

Now it is no longer possible to log in from my phone with SO UBports (Ubuntu touch)...
(I also opened an issue here, if helpful :https://gitlab.com/ubports/development/core/morph-browser/-/issues/549 )

And there are no alternative browsers: I tried Onion browsers and others available on OpenStore... and also those that can be installed with Libertine (Midori, Firefox, etc.)

So it seems that now all those who have "UBports" phones can no longer access Tutanota!

Will it be when 20.04 (now UBports based on Ubuntu 16.04) is available? Who knows? And it will take months…years… ?
Isn't an exception possible for UBports?

Alternatively the only workaround that comes to my mind is to evaluate another email and leave Tutanota...

The fix in #5230 added CSS test document.querySelector("blockquote:not(blockquote blockquote)") which requires Selectors Level 4 implemented by the browser (according to this article)

This is supported in browser versions starting from Chrome 88, Firefox 84, and Safari 9.

It is fair to unsupport old browsers and not let them use the app. The only problem is it prevents login, and if you don't login for 6 months you lose the account. Ideally the more advanced compatibility checks would run after login to at least let older clients keep the account alive.
