Pointless on an up to date FF (137)... can't even open the extension to see history (greyed out). And of course FF History is still limited to a pathetic 7 days

More than 9 years old and still updated. Im honestly surprised more people don't need this functionality

It did ruin my history before... Beware of the number in config, 999999 is kinda small for someone. ****, I don't know what to saw now...

Beware this addon will wipe all your history when it first runs. My expectation was it would give you the option to pick X days in the beginning. It will wipe all by default, then you can set the X days afterward. Totally defeated my purpose for installing it. :(

Thanks for creating this add-on. Works great.

Must have!
Funktioniert perfekt!

Works like a charm, set history clean for 7 days, gave it some time - history after week is gone. Shame they removed this from standard functionality after Firefox 3.

I set this add-on for 31 days and... this adon is not removing removing my history after 31 days.
