4.1.0 is working neither as well as the old version I was running (I am wondering if I was running version 3-something since 4.0.2 is having the same problems), nor doing the things indicated in the snapshot images on the main Mozilla page. I am no longer seeing the trash icons on the download and "sniffer" tabs. At least on the sniffer tab there's a "clear all" button (still no trash icons on the individual items the way there used to be), but it only clears items from the sniffer tab. I had downloads freeze multiple times on a site (I don't think I am allowed to post links to it here according to the terms) that normally has no issues. I had to disable the extension entirely and start it again. In a few cases the download would reach 100% but even after waiting 5 minutes no save window would appear. I ended up having to download a single video at a time (I used to do two at the same time with no problem), ideally doing nothing else with my browser while downloading, then keeping my fingers crossed the save window would appear. 4.1.0 is nice in that it saves as .mp4 . I downgraded to 4.0.2 to see if that improved things some but it didn't and then I also lost the direct to .mp4 capability.
Otherwise this is a great add-on and I have really been appreciating it and the developer's effort for the past couple of months. I was so glad to find it! Other add-ons will do similar but they require you to install additional software, sometimes at a charge.

Using Firefox 115.10.0esr. Maybe some of the lack of features appearing and the rough interface is because I am using an older FF version (I have an old computer). I would have given it a 5 on the benefit of a doubt about that, but the new version is really making me consider downgrading to version 3, so I am docking a star for that.

Edit since the developer specifically requested this:

Great Job the New Version is Crap, the older one works easely and fine the new Version doesn´t work.... useless Crap

The new version 4.0.2is not usable on different Win 10/11 systems with older hardware.Only a switchback to 3.2.1 works.

Unfortunately, the new version does not work because nothing is downloaded. The old design is much nicer. Where can I get the old version for Firefox again?.

Comment mettre à jour à la version 4.0.1?

Easy to break, and difficult to fix

Downloaded one video. After I cleared it, extension stopped working. Uninstall and reinstall didn't work.

Didn't let me choose download location on first try, or in settings. I'm sure there are other problems, but it broke too quickly to find out.

No idea what people are complaining about, this does exactly what it says it does.

Unable to detect streaming video on streamingcommunity.express. Paste the Url doesn't work.

awesome!

Useful tool. Although very rarely it's unable to capture stream.

Worked like a charm on an obscure streaming site!

Works great, very convenient. Unlike external stuff (yt-dl or VLC) it allows downloading stuff that is locked behind authentication with no hassle.

Infelizmente parou de funcionar a 3 dias
