Well, it just doesnt work on LinuxMint Firefox. Just keeps on trying to connect. Of course I have provided the flag in my client config. Doesnt work on Chromium browsers either. Thanks for wasting my time. Apollo is great, this extension sucks.

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.

Apollo Client Devtools requires a few 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.

Apollo Client Devtools is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
