Vlad This has definitely something to do with the Sync feature. I've been experiencing the same page reload problem on random web sites in random tabs. And it's not even a page reload, actually — Orion just navigates to the same URL as the first one in the history for the given tab at some random point in time and it happens for several tabs at once. Looks like an iCloud Sync event occurs that makes it do so. Another Orion instance open on another MacBook may be also affected, may be not — but when it is affected, it either does the same or just randomly tosses the same tabs around when it happens. Disabling Sync on one of the devices is a 100% working solution for me that stops this madness. But Sync is so practical...
I have Orion installed for only a couple of days but I'm already in love with its slick UI and all (I'm an Arc switcher where I switched to from Safari — can't stand Chrome and Firefox monsters at all for too many reasons). Please let's get it fixed -) Your browser is amazing, the dual extension support is just brilliant (even though it's not 100% complete). I can provide you with more details if necessary.
PS. Orion.app "About" details:

Build date Oct 27 2024
Mac Studio (macOS Sequoia 15.1.1 build 24B91)
PPS. Disabling Sync on both devices and then reenabling it again seems to help as well (no more random reloads since I did it last time a few moments ago). But I experienced it before and my guts tell me it will happen again soon.
