Is this extension still safe to use? (regarding X/Twitter's recent 'inauthentic behavior' purge)

[user5183801133]

I got hit with the ban at the end of May, I think it was because I used VPN + uBlock and I like/RT a lot (wasn't using this OldTwitter extension as I had it on Chrome, my main browser is Firefox). After I got unbanned I notice my old bookmarks before the ban aren't showing up even till this day, then I remember this extension could show total number of bookmarks of an account as 'favorites'. So I wanna use this extension to check if X has just straight up deleted my old bookmarks or if it's just like a glitch or something but I'm scared to use it since X and its AI detection are going crazy with their enforcement atm 😣
