I don't see that. There is a Hosts files tab and a More tab. But I use the pre-compiled hosts lists because I don't know all the bad sites, especially without visiting them first. It's the same concept as content blocking filter lists.

Maybe there are no updates? If there are still issues report them in the support thread.andyprough wrote: ↑2025-08-04, 18:16The hosts files don't seem to be updating even manually for me right now. Do they need to be updated occasionally?
There's a tab to write rules manually. If you type the right commands the extension can behave more aggressively and work even with hosts files disabled.

Re: uBO + eMatrix problem
I had that problem recently myself. I opened nMatrix-dashboard selected the about tab clicked on backup to file button, completely shutdown browser, then went into my profile sub-directory and deleted the ../ematrix-data/ematrix.sqlite file. Restarted browser, opened nMatrix-dashboard, selected the about tab clicked on the restore from file button, selected previous saved file and all worked properly again. Was able to update host files.andyprough wrote: ↑2025-08-04, 18:16The hosts files don't seem to be updating even manually for me right now. Do they need to be updated occasionally?

I'll post this over on the eMatrix support thread.
