Upon entering a URL (i. e. "http://www.radcollector.com/") in the input field, expected behavior would be that the button labeled "Add" became active. Nothing happens. As a result, it’s either “All on” or “All off” as far as Flash goes. Reproducible: Always Steps to Reproduce: 1. Open Preferences, go to "Web Features", click the button labeled "Edit Flash exceptions list" 2. Enter a URL 3. Notice that there is no way to actually add the URL to the list
The validation code is designed to work only with hosts, not with full URLs; entering www.radiocollector.com will work (there's placeholder hint text in the field, but you only see it if the field isn't focused, which it is by default). I think maybe we need to allow protocols to be entered (and, if a protocol is present, validate it that way) and then stip them before committing to Flashblock's exceptions list.

Summary: Flash exceptions list does not accept input ("Add" button stays greyed out) → Flash exceptions list does not accept input of full URLs ("Add" button stays greyed out)
Also, email@example.com, you can use the context menu item on any blocked Flash to automatically add the site to the exceptions list, with no need to enter any data manually: http://caminobrowser.org/documentation/annoyances/#whitelist_flash
Did try removing "http://". Same result.
(In reply to comment #3) > Did try removing "http://". Same result. You also have to remove the trailing slash shown in your original comment, since it's an invalid character in a hostname.
In the channel, Stuart suggested what we should do here is: Add a formatter that 1) Stript paths on paste ("/" or "/baz") 2) Prevent users from typing a path ("/", etc.) once there's a host or scheme+host entered Then, on commit 1) Strip the protocol scheme from what we pass to Flashblock's internal list As an added bonus, the same formatter+commit logic should work for popups (bug 370722), too.
I'll have a patch for this shortly.

Philip, does Flashblock accept ".foo.tld" domains, or treat "*.foo.tld" any differently from "foo.tld" itself?
I'm really bad at regexp but here is our current code: var expr = gFlashblockWhitelist[i]; expr = expr.replace(/\./g, "\\."); expr = expr.replace(/\-/g, "\\-"); expr = expr.replace(/\?/g, "\\?"); expr = expr.replace(/\+/g, "\\+"); //expr = expr.replace(/\*/g, "[A-Za-z0-9_\\-\\.]*") //expr = expr.replace(/\*/g, "[^ \t\v\n\r\f]*") expr = expr.replace(/\*/g, ".*") if (expr.slice(-2) != ".*") expr = expr + ".*" expr = expr + "$"; // "^" + var re = new RegExp(expr); if(re.test(host)) return true; So since I removed the "^" from the regexp some time back I would expect "foo.tld" to be the same as "*foo.tld". Of course I could be totally wrong since I've never been able to wrap my head around regexp.
I tried adding "*.foo.tld" and "foo.tld" to the exceptions list in a nightly build this evening. Both were written to the pref as "foo.tld", and both show up in the exceptions list as "foo.tld" (so we end up with duplicate foo.tld entries, *both* of which disappear when you delete one of them -- that's a bug in our current code, which aims to prevent duplicate entries). Based on that current behaviour and comment 8, then, it seems safe to ignore (prevent) asterisks entirely. If we prevent them and then find we get bugs filed about the inability to type wildcard characters (which Flashblock then proceeds to ignore anyway, just as it ignores schemes, so such an ability is of rather dubious utility), we could re-consider that decision. I *think* this is the first bug we've ever had filed on that input field, so typing in this field seems unlikely to be a very common user action to begin with, and wanting to type wildcard characters at the beginning of a hostname seems likely to be even less common. cl
Created attachment 418528 [details] [diff] [review] fix v1.0 A few comments/questions about the patch, which I'm sending to hendy for review... 1) Would it be better to store the |illegalHostnameCharacters| character set as a member variable on the WhitelistFormatter class? That way we only do that work once each time a formatter is init-ed, rather than every time a character is typed via isPartialStringValid:. My gut says this is a good idea, but I'd like someone to confirm that. 2) I removed the whitespace stripping on the popup exceptions list commit code because the formatter takes care of that for us. I didn't bother commenting to that effect in the code because it's kind of difficult to comment on code that isn't there any more ;) 3) I'm not totally tied to the idea of preventing someone from entering "com", for example, in the popup exceptions list, but I think it's very unlikely that anyone besides dwitte, mvl, myself, and a handful of other people know how to use that permission properly. I think it's a bigger win to keep most users from entering something that drastic by accident, since the handful of people who fully understand what a "com" entry will do are also aware of other ways to create such a permission if they wish. If other people think we should give users enough rope to hang themselves, I'm OK with loosening that validation a bit. Regardless of the outcome of the discussion of point 3, I think we should prevent them from entering ".", which we currently allow. dwitte or mvl are probably the only two people who can say for sure, but I believe that entry creates a permission for all hosts in all domains in all TLDs; i.e., you could globally override the popup blocker by accident by typing a period in the whitelist field and hitting enter. If the consequences aren't that serious, it's likely a meaningless thing to add.
Created attachment 420964 [details] [diff] [review] fix v1.1, strips whitespace on paste hendy has some tests he's gonna run this through, but I figured I'd put the latest version of this up since it's probably what's going to be sent to sr.

Comment on attachment 420964 [details] [diff] [review] fix v1.1, strips whitespace on paste Validation passes all the tests I gave it. Adding unit tests to a prefpane bundle is beyond my current capabilities, however. Need WebFeatures.h with WhitelistFormatter interface declaration. Truncate comment lines to 80 chars. The non-kosher adjacent character checks could probably be reduced to a single if block within an enumeration of an array of the various cases. Probably is a good idea to make illegalHostnameCharacters a member variable.

This bug is nominated for 2.0.2 (because the current code for this new-in-2 UI makes the UI seem broken when people try to paste things that they think they should be able to paste), so for 2.0.x we need a code-only patch.

I've been thinking about this off-and-on for a while now. The question I keep asking is "what's going to surprise our users the least; what behavior are they least likely to think is broken?" Is it going to be the fact that they get pop-ups on every .com site they visit, even though they've enabled the blocker, because they accidentally whitelisted "com" via a bad paste or fat-fingering? Or is it going to be wondering why the button is greyed out with just "com" in the input field? Is it going to be the fact that Flashblock appears not to work on foo-bar.com because they entered foo+bar.com, or that the button is greyed out when foo+bar.com is entered in the input field. What about when they paste http://例子.测试/首页 ? Do Flashblock and the permissions backend understand IDN? Do they punycode, or are we expected to send them punycode? (We write the Flashblock whitelist, and we write UTF-8 IDN, but whether Flashblock actually works with that, I don't know. Permissions appears to punycode an IDN when we submit it.) In the second case, I think it's a lot messier; with IDN, we have a lot more to think about--beyond the fact this bug was essentially filed because our users found the disabled button more confusing when pasting in a URL that otherwise seemed valid. In the first case, though, I find it much harder to make an argument that we're causing confusion, since people aren't going to think of "com" or "*.com" as a valid URL, and there I'd prefer we err on the side of making our feature seem less broken by refusing obscure but wide-ranging-in-impact input syntaxes. That said, we really need a patch for this for branch in the next day or so, or this will miss the boat in 2.0.2.
