links not working

Hi

What happens when you try to view those websites in Firefox? Is there any error message?

Website open normally in Firefox and there are no error messages. I use Mozilla Firefox as my browser on my laptop. Recently (last few days) Dell and Mozilla have been updated with a restart required and since then I have had numerous problems with Acrobat Reader immediately opening a further copy of any pdf document which is already open when I switch back to the pdf document e.g. Gmail, website or File Explorer folder, such that I have had to uninstall Acrobat Reader to stop the problem and permit normal use of my laptop. I also noticed that a new uBlock Origin icon has replaced my previous AdBlock Plus. I haven't myself installed uBlock Origin so I suspect it was part of the Mozilla (or Dell?) update. A few minutes ago I opened up uBlock Origin to find that the "Click to block all pop-ups on this site" had been activated (not sure if my myself inadvertently). I have now deactivated the pop-up block and links now open up normally (so far). I'm still working to resolve the pdf issue. I'm not a techie so would appreciate any possible routes for solutions Malcolm Morton

Hi,

Mozilla definitely doesn't install or uninstall add-ons. I have no idea what might have happened, but you can try reinstalling your old extension.

Regarding Acrobat, it's their new feature: immediately open every file that appears in the Downloads folder. It can be turned off in Acrobat settings.
