Its the only barely functional split view for firefox despite YEARS of begging them to create one. Edge, Chrome and Opera all have it.
This extension is not perfect. You cannot resize this side window. its fixed for me.
But its better than absolutely nothing.

Has potential, but every time I close it, the page is gone, and I have to open again. Plus, an autohide and show on hover would be great.

Extension safety
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk
impact extension cannot do much harms, whereas a high risk impact extension can do a lot of
damage like stealing your password, bypassing your security settings, and accessing your
personal data. High risk impact extensions are not necessarily malicious. However, if they
do turn malicious, they can be very harmful.
Sidebar Tab requires a lot of sensitive permissions. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious.
This is determined by the publisher and the Firefox add-on reputation on
Firefox Browser Add-ons, the amount of time the Firefox add-on has been
around, and other signals about the
Firefox add-on. Our algorithms are not perfect, and are subject to change
as we discover new ways to detect malicious extensions. We recommend that you always
exercise caution when installing a Firefox add-on.
Sidebar Tab is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
