that's why i do everything that's transactional in an incognito window. i have plenty of non-incognito tabs but they're nearly all sites i log into on the regular such as lemmy. combine that with firefox's built-in privacy protections and ublock origin, which is a combo that absolutely wrecks a lot of tracking and browser fingerprinting scripts to begin with (i have actually done contract work for marketing communications people and it was crazy how many layers of defense i needed to peel back just to debug their shit) and most of that tracking becomes disjointed cookies that only span a single session each and are hella hard to correlate.
