sorry, search engines were not helpful. does anyone know of a lightweight browser that doesn't need installing but stores everything in the os user directory?

i have no it-permissions but want to provide my department with a suitable browser. we have ie and edge, but the latter deletes everything on closing which makes it unusable for my usecase and the it is not willing to set this up different.

ff portable can not be run from a read-only-folder and any other scenario either needs installing on every terminal or does not handle different profiles which is essential. i read that this is the case for any portable browser.

i'd like to set it up properly with neccessary start page, favourites, adblocker and so on but just in one network directory for maintainance reasons.

we run a web based application strictly local but each windows-user-account must have their own setting in this app (cookies or preferably webstorage).

am i asking too much for?
