I am experiencing the exact same problem; neither the Chrome or FireFox extension will install. The latter just results in a blank screen and the former just keeps cycling back to the cloudflare verification checkbox. This is now 2026 with an official release of Orion and one of the biggest oassword managers is still incompatible with Orion. Funny, it works in Safari - is it possible that the Safari extension would work (I can't test since I can't attempt to install it)
Without fucntionality of NordPass, I cannot switch to Orion as primary browser and can only use in very limited capacity as, hmm, tertiary browser.
I realize Kagi is a small team, it is still disappointing that I canot switch to Orion and have resorted to uninstalling it and looking to another browser to be my primary. I so wanted to install Orion on all "my" macbooks.
Is ther any movement forward on a solution for this isue?
