Hello ionone,
Google Chrome/Opera/Edge and anothers is based on Google Chromium.
But if using for the daily basics, Microsoft Edge is the best solution for the browsers use the same solution, but if you want improve more security and perfomance tweaks it possible with Edge Business (
https://learn.microsoft.com/en-us/deplo ... osoft-edge). And the best part, is compatible to another OS, linux for ex.
ionone, for you problem, maybe there any item in
%userprofile%\AppData\Local\Microsoft\Edge\User Data or in registry
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Edge is corrupted or illegible, and i think is not a bad idea the problem if continue delete your current profile at the browser, but before make an personal backup for your favorites, credentials (not recomend store on browser), and another features you using at your daily basics, and check if the problem persists. This point is solution, im using for this computer, i didn´t use the Google Chrome, i continue prefer the using Microsoft Edge, because is the solution provide to us, when we using this OS, but the solution maybe one point is this.
I am testing the website in the different platforms (
https://www.browserling.com/), with your points and didn´t check any problem, maybe the point to another , in your bookmarks, can you save the entry of your bookmark, and delete, and next go to the webpages you want and create a new point on your bookmark.
The third one, is more specific, you can clear specific cookies using on your address bar
edge://settings/clearBrowserData and go to delete specific cookies with some date references.
I hope maybe this helps, and is document for Microsoft Edge, but the Edge and other programs use the same logic.
