It all works for me without any REDIRECTION, so rather than it being a Firefox issue it seemed to be more likely a malware issue that happens to be affecting Firefox at present.
I note from your comments that you see redirects. You provided a link to a ublock warning That would appear to indicate the problem is adverts and advert scripts. The ads served may vary because of tracking information on different users. You may find it helps
To adjust ublock settings - contact their support site for help & advise
https://discourse.mozilla-community.org/
If you do post a question over their feel free to cross link to it by posting the link in this thread. It will be interesting to follow it to see if thy offer a solution.
Try in Private Browsing with tracking turned off. Please see
Private Browsing - Use Firefox without saving history
Tracking Protection in Private Browsing
Malware does sometimes affect only one browser or one browser account/profile, but some malware later spreads or additional malware is downloaded.
There may be further investigations you could try on your computer, but those get rather tricky, and I would probably then need to obtain additional help myself with interpreting the results. The ublock support forum is probably your best next step for now. Please try that and say how you get on, and please reply posting a link to your ublock question. Thanks.
To add to John’s kind efforts to find a solution:
I have tried the web-site algarvedailynews.com via Private Browsing and Internet Explorer (which I have purely as a back-up). I also had Do Not Track as part of my Ff setup and have now installed u-block-origen, as suggested by John.
My own solution is to view each article separately on another tab, always using the Ctrl+Shft+Del to clear EVERYTHING once the page has finished all its down-loads…
I can now always use the icons, click on Next, add a comment without being ‘frozen’ or a redirect opening in another window. 
Not ideal, perhaps, but workable…
Thank you again John AND Firefox!
