I created a *.json file and cannot find a way to open it to reinstate the bookmarks that I had in Firefox. I do not have bookmarks in other search engines, it seems the only help it for that type of problems. I read other help articles, I do not have the things that were advise from Application menu. I did not make any changes to this laptop either, I cannot understand why my bookmark had disappeared???!!! What I had was a windows soft reset, which did wipe the bookmarks. Today I had opened a couple of websites, and when I look for the bookmarks I am only shown these 5-6 bookmarks!!!! I had loads as crafts from You tube and others! Such an inconvenience!

Chosen solution

There was a file called OldFirefoxData, so my boyfriend managed to restore bookmarks somehow!! Thanks for advice.

Hi, the JSON files are used with the Restore feature. More info in this article: Restore bookmarks from backup or move them to another computer. Does that work?

If that does not work, if you haven't already, please do a normal shutdown and/or restart of your system. Restarting Windows can help by freeing up locked files, completing any deferred updates, and resolving temporary file permission issues.

Next, if Firefox still has bookmark problems, could you let us know what you get when you run the "Verify Integrity" diagnosis and repair function. That's here:

Open Firefox's Troubleshooting Information page using any of these methods:

  • "3-bar" menu button > Help > More Troubleshooting Information
  • (menu bar) Help > More Troubleshooting Information
  • type or paste about:support in the address bar and press Enter

Near the bottom, there is a section titled Places Database -- that's the file which stores history and bookmarks. Click the button labeled Verify Integrity. There may be a 10-15 second delay before results appear.

If all is well, the report that appears below the button should start with:

> Task: checkIntegrity
+ The places.sqlite database is sane
+ The favicons.sqlite database is sane
> Task: invalidateCaches
+ The caches have been invalidated
> Task: checkCoherence
+ The database is coherent

Does yours say that, or something else? You can select and copy the report, and then paste it into a reply for review and comment.

What is a Windows soft reset?

Hmm, why would Windows wipe your Firefox bookmarks and history?

Windows does have a Refresh feature that can move all your data to a C:\Windows.old folder. If you see such a folder, let me know for more suggestions.

The exercise didn;t work, in fact "integrity" bit completely disappeared from that list.

So you started with this:

But after you click it, instead of getting a report like the following after 15 seconds or so, that whole section disappeared?
