open links in Waterfox (from another app)

It could happen that you cannot open links in Waterfox from another application (such as Thunderbird): blank page and all other tabs crashed.

To solve this issue, you can try adding %u to te Waterfox.desktop file (in .local/share/applications), something like:

Exec=flatpak run net.waterfox.waterfox %u

if you have Waterfox with flatpak

css :hover on a mobile device

There lots of java-scripts to allow an effect such as mouse over on a mobile device (that is without mouse), but there is also a very, very simple solution: to use :active instead of :hover, as in the following example:

@media screen and (max-width: 580px) {
  .tooltip:active .tooltiptext {
  visibility: visible;
  opacity: 1;
}
}

while in desktop screen you can keep
.tooltip:hover .tooltiptext {
  visibility: visible;
  opacity: 1;
}

sync murena on android nextcloud

When you are asked to set a server (opening nextcloud app on android), it’s enough to enter murena.io. Then you will asked for your user and password. (found here:: https://community.e.foundation/t/how-to-sync-nextcloud-notes-with-murena-io/47079)

A problem, if you connect your android device with KDEConnect and you copy your password from your PC, could be to paste it in password field. For security reason your keyboard could not allow you to paste easy. But eventually I managed to paste it without typing it.

router settings

In this case, as in many other, it a good idea to backup your settings. Indeed if you do a hard reset of your router, you loose your settings.
To backup settings you should use a browser (web-like) interface (firefox, or chrome, or an other one) using a url like http://192.168.1.1/ or something similar, and search for “backup” (or “save”) router settings.

syncing firefox

Symlinking logins.json is not possibile, you have to copy it every time. And it is necessary that logins.json matchs to key4.db.

webdav after changing cloud password

I.G. you could have changed the psw switching to 2FA. So, in Linux, Dolphin o any other file manager could not recognize any more your cloud webdav.

To fix this problem, try the following steps:

1. in system settings -> KDE Wallet -> Wallet Manager -> Passwords – > Maps,

2. find your old cloud account and delete it,

3. then you will asked, as expected, for a new user and password.

4. And then it should work.

KDE Connect not working

You have both smartphone and PC connected at the same network. But no connction between the two.

A possible reason is a firewall on the smartphone, .i.g. ReThink. In this case you should exclude KDE connect from firewall.

After several unsuccessfull attempts to fix a Vivaldi NO_PUBKEY error, I found this working solution:

and then:
