Losing passwords and bookmarks when updating Brave

I have a single laptop computer running Ubuntu 24.04.2 LTS and Brave Version 1.70.119 Chromium: 129.0.6668.70 (Official Build) (64-bit). It has just come up Brave is out of date again!!! Each time Brave needed to be updated it did not keep passwords or bookmarks. I need a way of storing my passwords bookmarks and possibly history locally so that I can put them back into Brave when it has finished cocking up, This has happened on the last two “UPGRADES” and I am fed up with having to re enter everything manually, If there is no solution to this I will probably trash Brave and look for a more user friendly Browser, rather than try to “Upgrade”. Does anyone have any constructive suggestions as to how to achieve this ?
