Have used this site for years. It was recently updated

Soluzione scelta

To see whether an extension could be related to this problem, you can try accessing the site in Firefox's Safe Mode.

You can restart Firefox in Safe Mode using

Help > Restart with Add-ons Disabled

In the dialog, click "Start in Safe Mode" (not Reset)

Any difference?

Safe mode does not automatically disable plugins. If you think that the site uses one of those and you want to see what happens when it is disabled, you can do that manually on the Add-ons page.

orange Firefox button (or Tools menu) > Add-ons

In the left column, click Plugins, then change the suspect plugin either to Ask to Activate or to Never Activate and reload the page.

Any difference?

More generally, after a site update, Firefox sometimes retains old data that can cause a mismatch (mish-mash) problem.

When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.

(1) Bypass Firefox's Cache

Use Ctrl+Shift+r to reload the page fresh from the server.

Alternately, you also can clear Firefox's cache completely using:

orange Firefox button (or Tools menu) > Options > Advanced

On the Network mini-tab > Cached Web Content : "Clear Now"

If you have a large hard drive, this might take a few minutes.

(2) Remove the site's cookies (save any pending work first). While viewing a page on the site, try either:

  • right-click and choose View Page Info > Security > "View Cookies"
  • Alt+t (open the classic Tools menu) > Page Info > Security > "View Cookies"

In the dialog that opens, you can remove the site's cookies individually.

Then try reloading the page. Does that help?

Cleared the cached web content and also entered site thru different route i/o bookmark. Re-saved bookmark and all works well. Thanks
