Browser keeps crashing

At a minimum, I'd recommend also setting up a USB stick as a second swap drive. 8 GB should be sufficient, 16 GB would be plenty, 32 GB would be overkill. The faster the USB stick, the better, so try to use one that supports USB 3.2 (and plug it into a USB 3.2 port).

Maxing out the memory, hence freezing,
Disable the hardware acceleration in Brave Browser.
Clear all cookie & cache in Brave.
Are you running VM?

Let us know how you go.

i disabled the hardware acc in brave.

What is VM?

In disks I dont seem to have the option to turn my usb stick into a swap drive?

Trying using librewolf it very tasty without bloat on webside.

See #4 above.

Some older USB sticks have the ability to be set via a switch as read-only... if it's that old, don't use it as a swap drive.

no its a brand new one from sandisk

i had zorin on this stick and now i am trying to delete it which gives me an error.

This is the same pendrive what you have installed Zorin on this pendrive?
Use a terminal with a command cfdisk /dev/sdc
Then choose a partition and ther will be a delete then click yes.
TAB is how you going on buttons.

yes, is that a problem?

Unmount the drive first.

Same problem, it won't let me delete it

You cannot propably delete live partition when you using this pendrive. This is something like you want taken a car to trash but you still sitting on this car inside.

How do you mean I am using it? I just plugged it in deleted some parts of the partition but the last one doesn't work. How is it live?

then in terminal propably you must put a command umount -f /media/dev/sdc

When you umount that usb then you can format with cfdisk or gparted.
On gparted you have also option umount.

It says it is not mounted.

when you go on gear you can choose option repair a disk then format on some ntfs or fat.
This is bootable this is live ISO where you cannot propably delete that partition.
This is core.
You cannot delete a pendrive with linux live when you using that pendrive.

This propably help.

You must format that pendrive from another pc or another pendrive with live linux.
You cannot full format your pendrive and the same time using that pendrive with live linux.

OK i think we need to get back to basic's,
Extra ram/swap shouldn't be needed.

There's an underlining problem.

First VM = Virtual Machine, these can have huge ram usage.

here is a photo of 20 diff tab's open in firefox.

Here's firefox opened 20 times.

Can you please screenshot your monitor without Brave open & with brave Open.
And display here ty.

Ok, close down the Disks application. We're going to brute-force it.

Start Terminal, and enter:
sudo dd if=/dev/zero of=/dev/sdc status=progress

From your image, we know that's /dev/sdc, so we'll just use dd to zero the entire drive. That'll wipe that partition off the drive.

Once that's done, then you can follow the instructions in #4 above to set it up as a swap drive.
