◆ Introduced a mechanism to prevent tracking from super cookies
Super cookies are a general term for methods devised by advertisers to somehow track users that normally cannot be tracked, such as private mode, and have been used since third-party cookies were blocked by major browsers. It is used as an alternative to tracking. Firefox 85 has taken steps against the super cookie technique of using cache to track users.

Until now, Firefox has shared a cache of image data etc. between websites, for example, if the same image is used on another site, displaying it from the browser cache saves the user's data traffic and time. was doing. However, some advertisers have abused this mechanism to identify users, and Firefox 85 now has a separate cache for each domain. Due to this effect, the page load time will increase by up to 1.32%.

◆ Bookmark bar is convenient
You can now remember in which folder you saved your bookmarks and show them the next time you bookmark, as well as the bookmark toolbar when you open a new tab.

If you want to place a bookmark on the toolbar, save the bookmark in the 'Bookmark Toolbar' folder.

◆ Password manager login information can be deleted in one shot
After clicking '...' at the top right of the 'about: logins' page, you can delete all login information in one shot by selecting 'Clear all login information'.

Support for Adobe Flash will end at the end of 2020 . After Firefox 85, I can no longer see Flash content.
