Whey trying to download a video in Chrome or Firefox in a MacBook Pro M1 Max, OS 26.2 Tahoe, I get this error. It downloads ok but when saving it gets this error.

Any Idea/hel?

Thanks

I have the same issue with the extension on Firefox after trying 5 times!

any chance to get the video you are trying to download?

+1 also having this problem

@SnowPowerCore can you share a link to the video so I can test the fix?

[SnowPowerCore]

@puemos i don't think i will be able to share a link to NSFW video :/ I will try to find any other video that also produces this error.

try with these and tell me if it works (new unreleased version)

The Chrome zip can be loaded via chrome://extensions → "Load unpacked" (after extracting), and the Firefox .xpi can be installed directly or loaded via about:debugging → "Load Temporary Add-on"

extension-mv2-firefox.zip
extension-mv2-chrome.zip
extension-mv3-chrome.zip

@puemos i just tried with extension-mv3-chrome.zip, sideloaded it to Microsoft Edge v145.0.3800.82. Same issue. I was using InPrivate mode (have ticked "Allow in InPrivate" in settings).

What's the size of the video?

[SnowPowerCore]

@puemos, approx 4.8 GB
