Been having a chornic issue trying to use Session in Yandex browser for quite a while now, for the longest time the extension seemed to work great in the browser and at one point had like 2 years worth of saved sessions I had saved and would back up, but after a while the extnesion would bring up a "still loading" screen when opened, and eventually just woudn't open at all like

I'm not sure what the reason is for why Yandex seems to have this problem with session buddy after what I assume is an accumalation of the file size getting to big and crashing after the extension has run for a long time, but if there's anyway you could maybe keep the browser in mind when devloping the extension so that it has full compatability without the extension breaking bug that forces you to remove and reinstall and even then that won't work to fix it, I'm sure it would be great not as well for the extensions overall stability.
