As mentioned on the extensions github page it is unfortunately no longer being maintained.

A new fork of this extension called Better History NG has all the most important currently broken features such as the history search fixed!

Sadly no longer working :-(

- BUT - Now forked to Better History NG :-)

Thanks to Vincent Parizet for creating this & to Christoph Wagner for taking it over !

I get "TypeError: visit.title is null" when searching history

I like the compact design. They should add the option to delete visited pages and show the URL. When I delete a page directly from Firefox history and return to the extension, it does not update with the information.

Does it look nice? Sure, it does. Is it better? Depends on what you compare it with. Search function is there, but managing history items is not even possible. No way to select items, let alone remove them. So, after noticing I had not used the plugin for months, I decided to delete it and guess what: I don't miss it AND the browser got a lot faster.

CPU overload

junk; it doesn't work; nothing is shown
*edit: It seems that the extension has a problem with some Firefox options. I have created a new Firefox profile and it works in that profile. Though it's not as nice and useful as Vivaldi history.
I need it to work with my profile and settings. What can be the problem? How to debug?
I have the same problem with the "Print Edit WE" addon.
