An important recommendation: OneTab Addon for Firefox.

[Member frtorres]

I have been using AntiX in a low memory box with limited resources.

I installed this Firefox add-on, with excellent results.

OneTab addon — “Save up to 95% memory and reduce tab clutter”

Home Site: https://www.one-tab.com/

Whenever you find yourself with too many tabs, click the OneTab icon to convert all of your tabs into a list in ONE TAB, saving memory having lots of tabs open while you browse the internet. When you need to access the tabs again, you can either restore them individually or all at once.

Conveniently you can export/import to/from text files your bookmarks to make your own collection.

Hope you enjoy it.

Francisco

When the original post above was posted, I understood what such a one-tab plugin would do, and I thought it would be a “good-to-have”.

Turns out it is a life-saver, if some of your computer happen to be at the low-end of the spectrum (which might be the case in the community here).

Specifically, if a computer does not have plenty of memory yet you open too many tabs in your browser (who doesn’t?), a newly opened tab could become the last straw to bring your computer into Thrashing mode. The symptoms include: CPU usage go high (and go red); Hard disk light flashes (if you have a swap file on hard disk, that is); and the entire system become very unresponsive. At this point, if you do not want to reboot and lose all your current Desktop session, your only option would be: (1) to start a Terminal console; (2) Run a ps -ef|grep firefox to find its PIDs; (3) Run a kill PID to close Firefox. These procedure is slow because each keystroke would take seconds.

But if you have One-Tab plugin already installed, you just need one click on that funnel icon in your browser. And then get up to refill your coffee, when you come back, most likely One-Tab has closed all Firefox tabs for you.

Thanks @frtorres for sharing this useful tool!

Hi, two brief comments (stumbled across this when searching for another topic related to FireFox):
1) @rayulo: kill:
You can achieve it more swiftly if you use pkill
pkill <process>
or alternately you can create a shortcut to run the below command:
kill -9 $(ps -U $(whoami) | grep -i <process> | awk ' { print $1 } ' | tr '\n' ' ')
where the switch ‘-9’ is more forcefull and it can be applied to ‘pkill’ as well

Decoding the $(…) part:
$(whoami) = current user
ps -U $(whoami) | grep -i <process> = all processes described by <process> name (case insensitive ‘-i’)
awk ‘ { print $1 } ‘ = print 1st column only
tr ‘\n’ ‘ ‘ = replace ‘\n’ EOL (end of line) by white-space ‘ ‘, i.e. column into a line

See the manual pages (‘man pkill’ in a terminal).

Edit: You can define a BASH function in your ‘~/.bashrc’ file accepting a single argument, the process name

function force_kill(){
  # Force kill process
  local proc_name="$*"
  if [ -z "${proc_name}" ]; then
    echo "No process name specified, nothing to kill [return]"
    return;
  fi
  kill -9 $(ps -U $(whoami) | grep -i "${proc_name}" 2>/dev/null | awk ' { print $1 } ' | tr '\n' ' ')
} # force_kill

and then simply call it
force_kill <process>
WARNING: The function has not been tested!

2) nice:
When starting programs that may eat up a lot of resources, you may call them as follows
nice <program>
or you can specify the niceness; this reduces their priority when accessing resources of your device.

I have defined custom shortcuts, e.g. Ctrl+Alt+F = /usr/bin/nice /usr/bin/firefox –private-window

See the manual pages (‘man nice’ in a terminal).
