Over the past few months, I’ve picked up a few handy Firefox tricks.
Address Bar
Find open tabs: Press Ctrl + L (or Ctrl + T) to focus the address bar, then type @tabs or %, hit space, and start typing the tab’s name.
Search browsing history: Press Ctrl + L, type @history, hit space followed by your search term.
Duplicate the current tab: Focus the address bar with Ctrl + L, then press Ctrl + Shift + Enter. (It opens the same page in a new tab, but without keeping the original tab’s history.)
Tab Management
Quickly duplicate a tab: Hold Ctrl and drag a tab to another spot on the tab bar, or just middle‑click the refresh button.
Select multiple tabs: Use Ctrl + click to select specific tabs, or Shift + click to select a whole range.
Move selected tabs to a new window: After selecting tabs, simply drag them out of the tab bar.
Mittels about:unloads kann man in Firefox eine Übersichtsseite aufrufen, die einem auflistet, welche Tabs wie viel Speicher verbrauchen. Hier können inaktive Tabs mit hohem RAM verbrauch auch entladen werden. Seit Firefox 140 kann man mit einem Rechtsklick auf einen Tab oder eine Tabgruppe und der Funktion Unload Tab dies nun auch manuell für bestimmte Tabs erledigen.
“Ventoy is an open source tool to create bootable USB drive for ISO/WIM/IMG/VHD(x)/EFI files. With ventoy, you don’t need to format the disk over and over, you just need to copy the ISO/WIM/IMG/VHD(x)/EFI files to the USB drive and boot them directly.”
“Pywal is a tool that generates a color palette from the dominant colors in an image. It then applies the colors system-wide and on-the-fly in all of your favorite programs.”
I’m using Variety to change my wallpaper every day automatically. To always get the right colors in my terminal I added some lines in my .zshrc that will always grab the current wallpaper and pass it to PyWal. I’m sure a bash pro would do this in just one line… 🙂

In meinem NAS nutze ich seit vielen Jahren als Motherboard ein ASRock C2550D4I mit einer recht stromsparsamen on-Board CPU und einer BMC/IPMI Schnittstelle, welche Fernwartung über einen separaten LAN Port möglich macht.
Bei einem BMC Update hat sich leider die WebGui verabschiedet und ich musste mir die Sache auf der Konsole anschauen. Dafür habe ich IPMITOOL installiert und verwendet. Dabei stellte sich heraus, dass lediglich die Netzwerkeinstellungen verloren gegangen sind.
Hier einige hilfreiche Befehle im Umgang mit dem IPMITOOL, welche mir geholfen haben. Über diesen Weg lässt sich ebenfalls das Passwort des Admin-Users zurücksetzen.
