Nah, Cromite doesn’t allow extensions. Other than the built in ones, it doesn’t do extensions. There was another Chromium android browser that could do extensions, Kiwi I think. But it was a smidge shady how it did its search queries so I’d avoid it.

And side note: Cromite’s Fdroid repo link is shot. It’s been down for me for month, and I tried disabling VPN or switching to other countries and i either get a timeout or not found error, similsr to this forum post. So like I’d have to keep downloadong apks to keep it up to date, and I’d rather just pray every website i use works on FF than do that.
