FWIW,
After correcting the URL, the PGE site seems to render fine with both firefox and dooble5. I've not tried dooble6. Both the firefox and dooble. This box is not quite fully updated. Both browsers are not the most recent versions.
With firefox, I typically recommend testing with a fresh profile, just in case.
Thanks! I had not bothered to check with Firefox for several years. The pge.com website had not worked for a long time. Today it works in Firefox. They do fix these websites, apparently, sometimes.
After succeeding in Firefox, I tried agian in dooble, but this time I deleted %HOME%\.dooble. Dooble is able to operate the website, aslo.
I'm sorry to have to delete my profile all the time, but since dooble does not have much for bookmarks and nothing for passwords, deleting the profile doesn't have much of a downside.
