Hi, this was fixed in version 2.3.4 which has now been reviewed by Mozilla so you should be able to just update

Edit: they made another change, it's fixed in 2.3.4. If you don't want to wait for Mozilla to review it, you can install the beta by clicking "FirefoxSignedInstaller" on https://github.com/ajayyy/DeArrow/releases/tag/2.3.5
