Hello @kubiznak.petr
could you try in private mode and see if it work fine there or not
if it worked then the issue either with your cache/cookies or with one of your extension
if it did not work then try to create new profile from the menu and see if it work
hope that help and have a nice day 
Hi @justsomeone1 ,
Thank you for your quick reply. I tried all your suggestions but the behaviour is always the same. Btw restarting Brave also doesn’t help.
Any other suggestions, please?
@kubiznak.petr,
Would it be possible for you to share a short recording of the behavior?
Additionally, are you saying you’re unable to download anything at all, or are you only unable to download from a specific site or file type? For example, if you go to https://basicattentiontoken.org/ and on the landing page, right-click on the White paper link and attempt to download the PDF document, are you able to do so or is the behavior exactly the same?
I just realized the issue. I had a mounted network drive which was not accessible - this irresponsiveness should be rather reported as a KDE bug. It was a coincidence that I just installed the Brave browser, so I didn’t think much about other causes. I’m sorry I bothered you guys with a non-relevant issue, and thank you both for quick support!
@kubiznak.petr,
No worries at all and we appreciate you reaching out. Please don’t hesitate to do so if you have further questions or concerns.
