revert broken Fenix update 20.08.20 Firefox mobile

Update 2023: There are several Firefox clones now that bypass Mozilla's ban on plugins and the browser has been straightened out. I use SmartCookieWeb-Preview and it works very well. Make sure to download "preview" (not regular) and then go to Settings->Advanced->Sideload XPI and copy the URL of the xpi you want to install. This way you can use Violentmonkey and Bypass Paywalls Clean.

To use the old Firefox version (broken on many Big Tech websites now):

  1. Download the last APK version 68.11.0.
  2. Search the app in Google Play and disable auto-updates (three dots).

The update destroyed all your browser and plugin configurations. There is no sane way to get them back. Other than that, your browser will work again.

I am not aware that there is any fork of the old Firefox in the Play Store.

my Notion keybindings

If you haven't tried Notion yet, you should. It is the only tiled and tabbed window manager that truly works well.

The default keyboard shortcuts aren't the best however, and they aren't easy to remember either. I have been using Notion for 15 years now, and I wouldn't know how to do it any better.

  • The mod key is the windows key.
  • F2 opens Urxvt, F3 any command. Middle mouse click the window frame for a menu, or press F12.
  • C closes the window, add shift to kill.
  • Z/X are for switching workspaces "left/right". Add shift and you switch monitors instead.
  • WASD are for frame navigation. Add shift to split the frame in that direction and the cursor is placed in the new frame.
  • Q to tag frame, E to attach the tagged frame.
  • Tab cycles through frame tabs, with shift backwards.
  • R to resize (with arrow keys). Hold shift before to shrink.
  • Return is fullscreen, space is float window, space shift nudge, grave ( ` ) is scratchpad.
  • F10 Go to window, F8 disables Notion keybindings, F1 suspend.

Most things can be done with only the left hand (for normal use) and all vital things even with only the mouse (for watching Youtube on couch while eating). Things are easy to remember as they work akin to known shortcut configurations, like WASD for directional keys, Mod + enter for fullscreen or Mod + tab to cycle tabs. Or if its not clunky they work by abbreviation (C for close, R for resize), or spacial symmetries (Q -> E for tag -> attach sits atop of WASD, Z/X for left/right below WASD).

useful Linux command shortcuts

Record Audio

RECORD="filename";arecord -v -f cd -t raw | lame -r -b 192 - ${RECORD}.mp3

Convert Video: Works with Whatsapp and Instagram

VIDEOCONVERT=00:00:00; TOOO=00:00:10; VID=input_video.avi; ffmpeg -i $VID -ss $WHATSAPP `if [[ "$TOOO" =~ [0-9][0-9]:[0-9][0-9]:[0-9][0-9] ]]; then echo "-to $TOOO"; fi` -y -c:v libx264 -pix_fmt yuv420p -preset slow -tune zerolatency -crf 19 -level 3.1 -movflags +faststart -c:a aac -b:a 128k -ar 44100 `echo "$VID" | sed -r "s/\..+$//g"`.out.mp4

Convert (replace) audio files with mp3s

CONVERT=;find ./ \( -name '*.aac' -o -name '*.aiff' -o -name '*.alac' -o -name '*.ape' -o -name '*.flac' -o -name '*.m4a' -o -name '*.mp3' -o -name '*.oga' -o -name '*.opus' -o -name '*.ra' -o -name '*.wav' -o -name '*.wma' \) -exec ffmpeg -i '{}' -vn -ac 2 -b:a 192k '{}'.mp3 \; -delete

Grab screen with sound: There are actually several unresolved ffmpeg bug reports, because using x11grab along with alsa will result in immediate buffer underruns. But some dude on Stackoverflow figured out that you have to use the -rtbufsize and -probesize parameters. Format works for Instagram and Whatsapp. Better use OBS Studio though.

SCREENCAPTURE="out"; GSIZE="1080x1080"; GOFF="0,0"; ffmpeg -rtbufsize 1500M -f alsa -i default -video_size $GSIZE -framerate 30 -rtbufsize 100M -f x11grab -i :0.0+$GOFF -probesize 10M -c:v libx264 -pix_fmt yuv420p -preset ultrafast -tune zerolatency -c:a aac -b:a 256k -ar 44100 ${SCREENCAPTURE}.mp4 -y

Set default apps: This is a total hack. Like you can see, it deletes only the default apps from your preferences and then pumps all files supported by the listed particular applications into it, starting with the most favorable. If you do not do this, then file extensions will be opened by alphabetical order, which is total garbage.

Using new Laravel 8 Jetstream components

When switching from Laravel 7 to 8, one of the first things I noticed were the <x-jet-... components used for all of the scaffolding. Since there are probably hundreds of options to build forms and to simplify writing plain HTML tags in your templates, I decided to keep it all in one style and use the <x-jet-... for all of my templates.

Like you can read in the Livewire docs, you can pull the components into your project folder like so.

php artisan vendor:publish --tag=jetstream-views

But there is for example no <x-jet-textarea>, so how do you add new components?

Simply edit the file /app/Providers/JetstreamServiceProvider.php and add the following to the end of the boot() function and below:

        $this->registerComponent('textarea');
    } // <- end of boot()

     protected function registerComponent(string $component)
    {
      Blade::component('jetstream::components.'.$component, 'jet-'.$component);
    }

Now you can create and customize the component file in /resources/views/vendor/jetstream/components/textarea.blade.php .

<x-jet-action-message> <x-jet-action-section> <x-jet-application-logo> <x-jet-application-mark> <x-jet-authentication-card-logo> <x-jet-authentication-card> <x-jet-button> <x-jet-confirmation-modal> <x-jet-confirms-password> <x-jet-danger-button> <x-jet-dialog-modal> <x-jet-dropdown-link> <x-jet-dropdown> <x-jet-form-section> <x-jet-input-error> <x-jet-input> <x-jet-label> <x-jet-modal> <x-jet-nav-link> <x-jet-responsive-nav-link> <x-jet-secondary-button> <x-jet-section-border> <x-jet-section-title> <x-jet-switchable-team> <x-jet-textarea> <x-jet-validation-errors> <x-jet-welcome>

multi-row tabs in Firefox Quantum

This page or post was last modified on 2023-03-14 .

From here you can use this file.

And just put it into your profile directory like this:

~/.mozilla/firefox/horp5zpu.default/chrome/userChrome.css

Don't install the whole git repository, it is just clutter and not worth it. You can change the CSS file to make the tabs more managable. I recommend setting max and min width to 174px and also set "max-height: unset !important;" for "#tabbrowser-tabs".
