Chuck, you concluded your "About Add-on" description by saying the following for CLEO 6.0.
Quote: "NOTE: If you are getting a message complaining about not having the correct version of FEBE installed (and you know the correct version is installed) see this post in the support forum."
I had FEBE 8.2 and was having this problem, above, so went to your website for CLEO and installed 6.0.1. Restarting Firefox seems to indicate that the problem is corrected, for the warning about CLEO not working until ... isn't appearing anymore. But, I checked the CLEO options and don't have one for not checking the version of FEBE, as you described in your first post of the forum thread for the problem quoted, above. So, I just wanted to inform you of this and then see what there'd be for reply.
Well, your forum login registration rejects GMail accounts that have usernames containing a period or dot in the username portion preceding the @ sign or symbol, saying that GMail accounts can't have these periods or dots. Well, mine always has and it's the email address used for Mozilla as well as several other websites. They don't have any problem with periods in GMail usernames.
I have two other e-mail accounts, one with Yahoo! and the other with the ISP I use. The latter e-mail address has a period in the username while the Yahoo! one doesn't, but I don't want to use it for your forum. The Yahoo! account is for stuff I don't have and don't want sent to my other two accounts, both of which thankfully receive far less.
I don't know if the reason your website refuses GMail usernames containing periods is due to your own personal preference, for whatever reasons you might have for that, or if it's because your login registration software is mis-coded, or ...; but, if it's due to your own preference, say, then I wonder what on Earth the reason could be. What could possibly be wrong with using periods as separators for different parts of usernames for any types of Internet accounts? Many people use periods and underscore or underbar characters for separating parts of usernames in order to make them easier to read, say.
With the GMail account, the period was added by me, but in the case of the ISP, it's the company that included the period.
I don't want to use Yahoo! for using your support forums for your Firefox add-ons and don't think that it's possible to create a second GMail account for free. I once tried to do that and it didn't work, anyway.
And I didn't want to post this comment here but couldn't find an e-mail contact link anywhere at your website; not in the pages that were checked anyway. Hence, addons.mozilla.org was the only possibility.
