Along with Firefox's own security I use Adblock Plus add-on

@FineWine I'd recommend switching to uBlock Origin. ABP is known to take advertisers' money to put them on an on-by-default whitelist. In addition, uBlock Origin is significantly faster and more memory-efficient.

Did not know that sneaky bit so will uBlock ago - thanks

Using chrome when I get the error but fine with IE.

No other tracking blocking. A couple of AV extensions but had those before. Before Christmas and for the last 3 or so years there have been no issues using Chrome.
