I see a syntax error in a closure definition. I've a JavaScript file, which has the following function. I'm loading the JavaScript file from another function and calling sampleFunction() from it. var sampleFuntion=function(obj){ //Statement here; }; But Firefox shows a syntax error for the first line, which is the function declaration/definition.

Can you post it as plain text? –Barmar May 28 '14 at 6:42 @Barmar Just edited. Please check now. –Rupam Datta May 28 '14 at 6:47 There is no syntax error, there... Are there any illegal characters around that function that aren't rendering? –Cerbrus May 28 '14 at 6:54 @Cerbrus Yes I also feel the same. There is no syntactical error. Also I rechecked for any illegal characters. –Rupam Datta May 28 '14 at 7:04 So, exactly what error is the console throwing? –Cerbrus May 28 '14 at 7:12 | show 1 more comment 3 Answers 3 active oldest votes up vote 2 down vote As the indicated script line doesn't contain any visual syntactical error, the problem is probably either an invisible illegal character within that line like e.g. a zero-width space. In that case just rewrite your function and ensure you replace everything up to the beginning of the file. Or the line number i

The same code works properly on Chrome/Chromium, and Safari. I call this function to get a random generated token to set. function getToken() { var url = "/csrf_token_generate"; $.ajax({ url: url, method: "GET" }).done(function(data) { console.log(data); // Logs the data from the call var json = $.parseJSON(data); // Where the error occurs token = json.token; console.log(token); }); } The URL /csrf_token_genrate returns a JSON javascript application syntax object similar to {"token":"$2y$10$jcr.P3FNqeji6RqD93LnxeIKs9gYNiPj7cboahz8RCCSgKw7VOfhi"} In the URL, I am setting the Content-Type to application/json which works in every other browser. The error Im getting is this SyntaxError: JSON.parse: unexpected character at line 1 column 2 of the JSON data n.parseJSON() jquery.min.js:4 getToken/<() wheel.bak.js:94 n.Callbacks/j() jquery.min.js:2 n.Callbacks/k.fireWith() jquery.min.js:2 x() jquery.min.js:4 .send/b/<() jquery.min.js:4 The object that is being console.log()'ed is this Object { token: "$2y$10$60vxSZiVqushBLVHSR5jPO6MquD4…" } I just can't seem to track down why it won't work in only FireFox, but works fine in other browsers. UPDATE 1 I figured out that firefox was trying to parse an already parsed object, so I changed the code to be along this function getToken() { var url = "/csrf_token_generate"; $.ajax({ url: url, method: "GET" }).done(function(data) { var json = data; token = json.token; console.log(token); }); } Which now works in firefox, but not Chromium. So what is there to do than? javascript jquery json firefox share|improve this question edited Jan 6 at 1:19 asked Jan 6 at 1:13 hightekjonathan 173115 1 Will the call always return json? You could try adding dataType: 'json' to the ajax params and let $.ajax do the parsing for you. –Taplar Jan 6 at 1:17 @Taplar The second one. The first is just logging the data it

It happens randomly with between 1 to 4 popups at once, though I can cause it to happen manually by reloading Facebook or gmail (interestingly, this behavior doesn't happen with Google reader or Google plus). I'd like to do two things here. Firstly, have some way of actually telling what's causing this rather than try reloading tabs at random. Secondly, stop this from happening, either by fixing the issue or by suppressing these messages. So how do I track down and eliminate this issue?

This is even more likely just after a Firefox update, where API and engine changes may cause previously working extensions to break, or expose previously ignored errors. The first course of action when Firefox is crashing or throwing errors, especially across a range of sites, i
