Life-saving. Efficient and easy to use.
Allowed me to get back my entire history after an unfortunate accident.
It would be nice if it worked on mobile too.

I used it to export my history and make stats. It was very convenient.

Simple addon which allows to migrate all history from a device to another, because Firefox Sync saves only 1 month (30 days). If you’re history is large, please note the addon says it has finished whereas it still needs a while to export everything: be patient. 😊

I exported my Firefox history from one computer using one operating system, then tried Importing the history file on another computer in another operating system and nothing happens after selecting the file. It only weighs about 27MB, so I don't think it's chugging behind the scenes.

worked like a charm, thank you so much! was able to export my current history, replace places.sqlite with a way older version and reimport my current history. THANK YOU!

I have a profile from a previous browser and have uploaded that places.sqlite file into your extension. It appears in my downloads folder as data.json. My history has not appeared in my browser. I closed/reopened firefox. Refreshed firefox. Still nothing. Can you provide further instructions on how to load this json file into the new browser?

When I reset the password for my Firefox account, I did not realize I would lose all my history. Luckily, I was still logged in elsewhere and could pull an export so I didn't have to start from scratch. This extension worked amazingly.

One issue, though. I exported all of the history but it's not loading everything into my Firefox account. It says successful but I'm missing a couple of the older months and the "Longer than 6 months" section. Not a huge deal but is there a way to rectify this? Do I need to edit the JSON and feed two files versus one?

Thanks for your help ^^

One of the few(if not only) Firefox history mergers that still works! Really is a day savior.

This is great! Any chance you can enable it for Firefox for Android? It seems like in theory it should work there!

Only exports in JSON format, no other format available.

great extension for exporting your history, i just don't understand how to import it, what do i do after it says finished ?

Thank you so much! This is exactly what I needed to recover from a corrupted places.sqlite that my new profile was only finding 12 history entries but old profile still showed them all. Your History Export was able to grab nearly 139,000 records and import them into my new profile in under a minute. Then it took Firefox about an hour to parse it all and add it to my Library. Verified the integrity in about:support afterwards, all is good!!

Very handy thank you. Could you please make the title in the last column of the export, or use a less common delimiter? Will make import to excel easier, as titles can contain commas.

Nice add-on. I tried to export histories and it works well. But I didn't import with generated data.json file for one question: **will my current histories be overwritten when importing?** I want to merge my current histories with histories in data.json. Hope for your reply.

REPLY:
Thank for the description added,
and your (very fast) reply.
And i understand you don't investigate more for Waterfox Classic.

Maybe you can add in the description that the export button work too if we don't select a file:
In this case it export the history of the browser profile where the addon is installed.

And if we select an other file, it do the export from it...

I tested to use the Normal Export from the History widows of Waterfox Classic(a .json file),
and import it to Quantum:
Same results..
But it import too my Bookmarks folder (which i don't need).

Your extension import just the history, which i wanted.

But stay the visited links problem:
Maybe a cookies thing ?


Old Review:

Thank for this tool!
Not for all day use, but a time saver when we need it, for sure.

I tested to move my History from Waterfox Classic to Firefox Quantum.
Before, for the test, i deleted all the history of my Firefox Quantum.

A - Into the Option panel of your extension
- Select the "formhistory.sqlite" from my Waterfox Classic profile.
- Do an export (Obtain an "data.json" in my Download folder).

B - Open My FireFox Quantum.
- Select the previous "data.json",
- Click to the import button.
After a quick time, seems working fine!

Small problem:
I notice if the pages from my Waterfox are in the new history,
inside them, their links visited are not highlighting, like i expected.

For info, I keep my Browsing History and have a CSS for that.

My Request /questions:
1 - It's normal or i need to do something more?
2 - Maybe there are an incompatibility between Waterfox Classic and Quantum?

Another request:
For info too:
The Export seems not work with your extension installed in Waterfox Classic,
But for Waterfox to Quantum, all can be done in Quantum...
