Hi aditya,

> It is possible for you to check on a fresh install of manjaro in a
virtual machine to rule out the possibility that something else in your
system is causing this behavior.
I remember trying context while browsing the wiki before so it should work
normally in a brand new environment, but I don't think it's reasonable to
install a brand new distro just to make sure that 'context --help' can work
normally, no matter how problematic the current distro is, as long as it
does not prevent commands from displaying help messages.

&gt; Environment:<br>

&gt; Expected behavior:<br>
&gt; Nothing surprising should happen.<br>

&gt; Firefox suddenly eats 100% of cpu<br>

I cannot reproduce this behavior (I am on manjaro but using firefox 81 rath=

<br>
$uname -a<br>

<br>
I followed your steps:<br>
1. start `firefox --safe-mode`<br>
2. On a different terminal, open htop and filter `firefox` so I can view fi=
refox&#39;s CPU usage.<br>
3. Run `mtxrun --script font --list --all`<br>
<br>
The CPU usage of firefox does not change in any appreciable way (it was 0% =
and remains 0%). <br>
<br>
It is possible for you to check on a fresh install of manjaro in a virtual =
machine to rule out the possibility that something else in your system is c=
ausing this behavior. <br>
