Assuming Firefox is installed the snap way (appears to be default in Ubuntu):

Check if it a snap package:
type firefox
if it says

firefox is /snap/bin/firefox

Then uninstall it:
sudo snap remove firefox

To complete remove folders associated with it:
sudo snap rm -r firefox

Forgot to add that you may need to install wget:

sudo apt install wget
#33
I think that is trying to install a snap version.
To install from command line, open the Terminal and run this command:
wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
run this command to install Chrome using the offline installer:

sudo dpkg -i google-chrome-stable_current_amd64.deb

If you get errors about any missing dependencies you can force install them

sudo apt -f install

Then launch the app

Hi Melissa,

If you having problems with sudo (account login password incorrect) then either you are not member of sudo group
Test it by:
sudo whoami

enter your password, then it should say
root

If you get an error saying "user is not in the sudoers file", it means that the user doesn't have sudo privileges.

In that case you need the root password (I assume your brother set that up) to add yourselves to the sudoers.

You could try to run fsck manually:
fsck -fy /dev/sda2
then reboot

Linux Support / Re: Firefox high CPU

You could check disk usage with 'df':

df -h

look for disk usage in / and /home
for example Linux Mint XFCE:
Filesystem         Size  Used Avail Use% Mounted on
/dev/sda1           30G   20G  8.1G  71% /
/dev/sda6           46G   38G  6.0G  87% /home

your bottleneck is low memory and slow HDD
Check memory usage (example with 32gb memory):

free -m
                    total        used        free      shared  buff/cache   available
Mem:          32025        1971       26822         116        3231       29483
Swap:         30516           0       30516

It appears that the installed 768mb memory is shared with graphics (128mb in your case)
Leaving you with 640mb useable memory which is not much.
Firefox is not light and need to load into memory a huge ammount of data.
If the 20gb HDD is slow (which I suspect it is) the cpu usage you see is more than likely associated with
IO (reading and writing to disk).

You can check cpu & memory usage with 'top' (exit with q):
Look for firefox
top
%CPU %MEM     TIME+ COMMAND
1.3  2.0   3:33.67 firefox

or check disk access with 'iotop' (exit with q):
install with
sudo apt install iotop

again look for firefox
sudo iotop

You can check disk read (speed) with 'hdparm':
You may need installing
sudo apt install hdparm
then

sudo hdparm -tT /dev/sda
for example
/dev/sda:
Timing cached reads:   23440 MB in  1.99 seconds = 11775.92 MB/sec
Timing buffered disk reads: 1554 MB in  3.00 seconds = 517.42 MB/sec

The second line is the actual disk read (the first is read from memory)

I assume you are using LinuxMint.

If you are able to print the images yourselves, then you could try PhotoPrint:
https://community.linuxmint.com/software/view/photoprint

I have used that occasionally if I wanted multiple images on one page.
You can also export the image to TIFF or JPEG and send that to your printing company.

You could try purging the application while removing it:
sudo apt-get remove --purge <application>
then reinstalling it again

You should be able to continue to run DraftSight 2019 for free on Linux:
QuoteMac and Linux users may access DraftSight 2019 Beta below at no cost.

See here https://www.3ds.com/products-services/draftsight-cad-software/download-draftsight/

Otherwise you can follow the uninstall instructions from here:
https://www.3ds.com/products-services/draftsight-cad-software/uninstall/

Note, I am running 2019 version now and also BricsCAD 19.2 (trial) on Mint

Never used Zorin, so cannot test this, but as I understand it is based on Ubuntu so it should work:
sudo apt install transmission-gtk transmission-common

Have you considered that the breach might have occurred at Microsoft?

Sometime ago my daughter had an email address with outlook.com
Her account was breached, then MS locked her out.
After a long wrangling they admitted that it happened at their end.
She never used them again

General Discussion / Re: Address Book in Thunderbird
February 18, 2019, 08:42:59 PM
You could read about migrating here:
http://write.flossmanuals.net/thunderbird/migrating/
and
http://kb.mozillazine.org/Moving_from_Windows_to_Linux
also
http://kb.mozillazine.org/Import_.pst_files

Long time ago this is how I have done it:
1) Install Thunderbird on Windows
2) When Thunderbird starts it will offer to import Address book etc
Once you are happy that all is imported then
3) From Windows copy the contents of the Thunderbird profile over the profile (on your linux) in the ".thunderbird" subdirectory in your home directory.

Try commenting out this line in /etc/fstab :
sudo nano /etc/fstab
Quote/dev/fd0        /media/floppy0  auto    rw,user,noauto,exec,utf8 0       0
make it thus:
Quote#/dev/fd0        /media/floppy0  auto    rw,user,noauto,exec,utf8 0       0

then reboot and see if that reduces the boot time
