Restored session sites show up in whitelist on their own

[Jim]

This has happened at least twice. A list of sites that were in a restored Firefox session showed up in the whitelist. I don't know when because they show up in the entry as the full http: url and as such appear at the very bottom of the list. It's easily possible they were there a while before I noticed them since I would only see them if I scrolled past the grayed out entries for about: and such. I am using Ubuntu 11.10 and Firefox 13 although the first time this happened was with a previous release of Firefox. I do use Tabmix-plus to manage session restores and normally start Firefox by restoring the last session. I typically have 20 - 25 tabs in a session but only the first 10 or so get automatically added to the whitelist. All software is automatically updated and current.

I am posting this in case this is a known type of problem to see what might be causing this such as an occasional bug when no script updates while starting Firefox with a session restore at the same time? I'd be surprised if this were enough information to diagnose this problem if this is unique to me. I don't expect that and will start watching the whitelist to see if it happens again and have more specific data. Thanks and I'd appreciate it if anyone has any ideas on what might be going on or what to look for.

The first and most obvious question is, are you absolutely sure that you never temporarily allowed these sites? A session restore might have caused the whitelisting to be restored too. I'm not an expert on Firefox session persistence, though, and certainly not with Tab Mix Plus involved.

Next question, have you (ever) enabled the 'Temporarily allow top-level sites by default' option? It's in Options-General.

Third, if you regularly visit sites where you have to scroll to see all of the entries, then it may be worth marking some of the ones you don't need as untrusted, so they disappear from the menu. Just sayin'.

Very unlikely (at least, NoScript has no code allowing for that unless its initialization sequence, which clears the temporary whitelist, is skipped abnormally or crashes).

Next question, have you (ever) enabled the 'Temporarily allow top-level sites by default' option? It's in Options-General.

This is the most likely culprit of all.

Yes at time I have allowed scripts for at least some and probably all of them. However the interesting thing is all of the ones I'm describing show up in the whitelist in full url address format such as http://forums.informaction.com/, whereas, any sites I normally allow either permanently or temporarily show up as forums.informaction.com. The reason I didn't notice them is not because I have a long list of allowed sites, (I have a very short list), but because the sitelist displays the allowed sites and then it lists a number of grayed out firefox pages such as about:, chrome: and so on. Then after this list it lists the sites that start with http:/. Normally you don't scroll down past the about: pages because normally there is nothing after them.

Don't recall ever having a reason to do that but obviously who can seriously swear they've never done something by accident? Anyway, if I did, it was by accident and I never noticed it. It would have to have been on briefly during a restore because only 10 or so sites were listed and also it has happened twice.

However, I agree with Giorgio and you that it does sound like the most plausible answer since the default choice appears to be to list the sites with the full address as the ones I'm mentioning were listed. Anyway, thanks for the ideas and I'll keep an eye on the options!
