Firefox user interface

From mozilla forum:

  1. in about:config set toolkit.legacyUserProfileCustomizations.stylesheets = true
  2. clone & install custom CSS from https://github.com/aris-t2/customcssforfx
  3. uncomment @import "./css/tabs/tabs_below_navigation_toolbar.css"; in current/userChrome.css
  4. cd firefox_profile && rm -rf chrome && ln -sf /path/to/repo/current

Extra

My about:config settings

  • browser.download.alwaysOpenPanel = false -- fix naggin download panel since FF 98
  • browser.tabs.loadDivertedInBackground = true @
  • security.dialog_enable_delay = 100 @
  • browser.tabs.hoverPreview.enabled = false @
  • browser.tabs.hoverPreview.showThumbnails = false (Settings>General>Tabs) @

  • set a custom user agent:

    1. Add new string value general.useragent.override
    2. Enter your preferred UA
    3. Check it on https://www.whatsmyua.info/

    This is especially useful if you are on an ARM device (like raspberry pi) and google keeps giving you its mobile version, for example:

    1
2
    Mozilla/5.0 (X11; Linux armv7l; rv:60.0) Gecko/20100101 Firefox/60.0    # before
Mozilla/5.0 (X11; Linux x86_64; rv:60.0) Gecko/20100101 Firefox/60.0    # after

Date format (displaying input type=date fields)

Set intl.regional_prefs.use_os_locales = true then:

1
2
export LANG=it_IT.UTF-8
exec /opt/firefox/firefox

1. Partition table

# dump raw ms-dos table/mbr
dd if=/dev/sdX of=mbr.bin     bs=512 count=1
dd if=/dev/sdX of=mbr_2mb.bin bs=2MB count=1 # paranoia
# restore
dd if=mbr.bin of=/dev/sdX
  • using sfdisk (version > 2.26 for GPT support):

# dump raw partition table
sfdisk -b -O disk /dev/sdX # disk-<device>-<offset>.bak
# restore
ls disk-*.bak | sed -r 's/(.+)-(0x.+).bak/dd if=\0 of=\/dev\/sdX seek=$((\2)) bs=1 conv=notrunc/' | bash

# dump partition table in text format
sfdisk -d /dev/sdX > sdcard.ptable
# restore
sfdisk    /dev/sdX < sdcard.ptable

2. Partition data

You can use FSarchiver or the old school way:

  • ext* efficient backup/restore:
1
2
e2image -ra /dev/sdXY - | pv | 7za a -mx=9 -si sdXY.e2i.7z
7za x -so sdXY.e2i.7z | pv | dd of=/dev/sdXY bs=4K

or create a squashfs mountable image1:

1

11
apt install squashfs-tools

# backup
mkdir tmpdir
mksquashfs tmpdir sdXY.squashfs -p "sdXY.img f 444 root root e2image -ra /dev/sdXY -" -comp xz

# mount and...
mkdir tmpdir mntdir
mount sdXY.squashfs tmpdir
pv tmpdir/sdXY.img | dd of=/dev/sdXY # ...restore or...
mount tmpdir/sdXY.img mntdir         # ...inspect

Convert a .tgz backup file to squashfs using squashfs-tools-ng:

1
2
apt install squashfs-tools
gunzip -c file.tgz | tar2sqfs file.squashfs
  • ntfs efficient backup/restore:
1
2
ntfsclone -s -o - /dev/sdXY | pv | 7za a -mx=9 -si sdXY.nc.7z
7za x -so sdXY.nc.7z | pv | ntfsclone -r -O /dev/sdXY -
  • raw full backup/restore:
1
2
dd if=/dev/sdXY | pv | 7za a -mx=9 -si sdXY.dd.7z
7za x -so sdXY.dd.7z | pv | dd of=/dev/sdXY bs=4K

Tips: dd seek/skip
