Inside "Chrome Properties" go to the Tab "Previous Versions" go to an earlier date before you remember your bookmarks disappearing, select it, click the Button "Restore".Wait for about 10 to 25 mins and when you open Chrome your Bookmarks will be back. Due to an over-aggressive system cleaner utility I lost all my Firefox tabs, bookmarks, history, etc.I tried the solutions listed above without success, and then tried running a System Restore, which is included in all current Windows versions.
For example, if you need to access a bookmark that you accidentally deleted or make changes in your web browser that don’t update on your other devices, we can help.
This is because Google Chrome limits the number of updates you can make in a short period.
Microsoft Edge browser in Windows 10 doesn’t support i Cloud Bookmarks.
Reason: This will allow you to update your bookmarks from a single location, even though you have the Category / Folder in your Main Bookmarks folder as well as your Bookmarks Toolbar(For Quick Access).
Not having this feature creates a lot of unneeded file size and also has a negative performance impact on the browser due to the fact that currently you have to have two exact copies of a folder in two locations. Tags are great because one can assign an item to more than one categories. Anyhow, tags as implemented currently allow creation of flat structure only.
If you want to use i Cloud Bookmarks in Windows 10, use a supported browser, like Google Chrome, Mozilla Firefox, or Internet Explorer.
