Downloading doesn't work
I tried to download a file of 25 MB. Vivaldi downloaded 16 MB, then slowed down to a few kB (!), then after fifteen minutes, it stopped completely. I tried to download it several times, with the same result. I opened Edge, tried to download the file - and it took 7 seconds.
And it's not the first time. When I bought an album (wav format) few days back , Vivaldi showed the estimated download time 58 hours. I contacted my provider and they were baffled, because my connection speed seemed okay (I have fiber internet with the download speed 300 MB/s). I tried Edge - and I got it downloaded in 3 minutes.
In fact, it's about 99% of cases - I feel like doing a happy dance whenever Vivaldi actually manages to download the file. The issue started at the beginning of January, until then it worked fine.
I don't know what's wrong, but if it continues, I'll have to switch to a more reliable browser.
@Ventis: probably not the browser. Something on your machine or network is interfering with Vivaldi downloads.
