I've encountered a problem that has completely stumped me, and unfortunately I don't really know how to go about trying to diagnose the problem either.
Basically I have a client who's website loads and then just hangs using FF25 on OSX 10.9, it only happens on this website, no other website. I've heard of problems before with this combination that resulted in people having to disable their plugins, so I told them to disable plugins/clear cache and get back to me. They've done this but to no avail. I've also read that it may be a CSS issue with fonts(no idea why it would be).
I've been all over the Mozilla forums but no one has raised such a query that replicated my problem on just a single website. Here probably isn't the best place to raise such an issue, but I'm sure someone must of encountered the same problem and resolved it some way or another.
Thanks.
There are memory allocation issues that appeared in FF25 (certainly on Windows; FF26 and 27 seem much "better"). These issues seem to be js/heap related. See, for example, https://bugzilla.mozilla.org/show_bug.cgi?id=936784
You can investigate yourself how the browser is using memory by browsing to about:memory in a new tab.
It seems a little odd that this does not happen if the browser console is open - and even after closing the browser console and refreshing the page it continues to load fine.
What might be happening (or not happening) with the console open which would prevent this error from happening?
We've tested it on 10.7, 10.8 and 10.9 and all three have this problem, but only on Firefox 25.
In response to Codacoder, that bug appears to be related to leaving Firefox unattended and an ongoing incremental memory usage issue - this happens the second the page loads, rendering the browser un-usable and requiring a manual kill of the browser. Not sure if it's the same issue?

I am experiencing an issue related to the displaying of any content within the JxBrowser, but only for 1 specific client PC.
The JxBrowser seems to correctly process the content that is sort of present, because if I click on an area where I know there is a link, the new page is opened (but not rendered too).
The "pages are not displayed" means that the content is completely white. Furthemore, the pointer is repetitively blinking between the normal arrow icon and the waiting circle, as something is going on in the background every about 1 sec.
A previous version of the application that embeds the JxBrowser doesn't produce the same problem.
Later on, I have also upgraded the JxBrowser version from the 6.23 to 6.24.3, but this did not solve.
Deleting any caches produced by the presence of the JxBrowser on the PC did not solve either.
What should I investigate to try and address this situation?
First of all, please note that JxBrowser 6 is no longer supported and it's a very old version based on Chromium 69. A lot of popular websites might not work properly in this Chromium version.
If the issue is reproducible only in a specific environment, then it's probably an environment-specific issue. If we are talking about rendering, then usually Chromium cannot render content when there's an issue with GPU drivers and the rendering mode (heavyweight or lightweight).
From our practice, disabling GPU very often helps in such cases. Please try passing the --disable-gpu switch and see if it helps. If it doesn't help, then the issue is probably in something else and additional research or even access to this environment is required. But again JxBrowser 6 is no longer supported.
As an option you can try JxBrowser 7 and see if it helps, but it's not that easy because this version has a new API which is not backward-compatible with the previous version.
The problem is awkward because everything worked fine. I opened the laptop and somehow it crashed and didn't corresponding to any commands so I had to turn it off. After I started again and after building my project(just in case anything was wrong) and opened my web page I realized that bootstrap is not working at all, and I can't figure out why because I didn't do anything. I tried to install a lower version and didn't worked and after I install the latest stable version and not didn't worked again. If you need any source code let me know and I will edit my post. I will put a picture below which describes what I am talking about(or at least I hope so).
It has the appearance of running in IE Compatibility mode, even though you're on Chrome. Try refreshing your cache (Control+Shift+Delete), rebuilding your project, and using a different browser.
I've run in to this issue before and refreshing the cache usually does the trick.
I have created a location based app, and it works fine on the device. But on the simulator there appears to be sporadic issues where the location services just stops working. Everyday for the past few days, I have worked on the app using the simulator without issues, however when I come back into work the next day and start the app again, I am getting the usual error
didFailWithError: Error Domain=kCLErrorDomain Code=0 "The operation couldn’t be completed. (kCLErrorDomain error 0.)"
This happens to every location app I have, I have a few custom code examples I have I use for reference to check the issue is not just happening to my application. So this confirms that it is not a coding issue
Usually I can fix the issue, after a few attempts of resetting simulator, deleting derived data, double checking I have setup a simulated location under edit scheme. It usually takes a few attempts of trying this various techniques to get it working. But today I cannot get it working at all on the simulator.
Now I am sure after playing about with for longer, I will eventually get this working again on the simulator, but I would like to know the root cause of this issue. I am getting tired of every morning, repeating this routine of resetting sim, deleting data, as it is wasting time that could be spent actually coding.
Is this an issue with the Xcode 6.1 simulator? Why does this seem to happen quite often and does anyone else have a better solution to this issue?
I have filed a bug report with Apple as suggested by Jeremy Huddleston Sequoia. However for the time being, if anyone else has this issue, the only work around I have found to truly fix this is, first reset the simulator, secondly delete the derived data folder, then finally reset the mac. It is frustrating, but every day this week I have had this issue, and for the time being, this is the only solution I have found that seems to work, well sometimes. Hope this helps if anyone else is having this problem. If Apple respond to my error report, I will update my answer
it happens often to me and use xCode 6.1.
Usually Cmd + Shift + K, which is about the equivalent of resetting the simulator , I can make it work.
Other times , change device , launch the iPhone 5 on the simulator and on the iPhone 6 and then I go after ...
Strange thing ... I agree with you that it may be some sort of bug or poorly procedures initiated by the compiler.
Also because then once part after is always the simulator
I am using VS2010 on Windows XP pro (sp3, x86), and I just installed the hotfix kb2106584. This fix was reported by some people, example here, as having a fix for an issue I had with Asp.Net Development Server not getting opened properly from VS, which I was having previously. My issue was being caused by ESET NOD32 messing with the http traffic from devenv.exe and causing all the ports in my computer to get used up, however.
Anyway, as soon as that was finished, I opened my website back up, and clicked debug. Asp.Net Dev server pops up, which was what the hotfix was supposed to make happen, and then notepad++ opens with the tabs I had last time I used it, and IE never shows up. "Wait, what?" try it again. and again. Always notepad++, never IE, always with no new documents opened, just some completely unrelated stuff.
I've seen one other post on SO about this happening, here, but his issue was corrupted files/filesystem. My project is in source control, so I tried a delete&revert to yesterday's revision. Still opens notepad++, so that's not my issue.
I've also tried rebuilding, which did nothing, and deleting my local Solution files, which also did nothing. I restarted the program and then the computer, both to no avail.
I start to believe that this is the hotfix screwing things up, so I try to do a system restore to a couple days ago. Once again, no dice; it's still pulling up notepad++ instead of IE.
So, the questions become:
Is there a setting or two I can try changing to make it open the proper program again?
Or was this a bad/improper hotfix, and if so, how do I uninstall it? It doesn't show up in the Add/Remove Programs dialog, and I don't see an option to uninstall it in VS, or in the installer.
Thanks in advance.
[edit] Also note: Notepad++ is not actually opening the website file, it's just getting opened with whatever I left in it last time. I dunno if this helps at all, but I felt like details would be appreciated. [/edit]
Fixed:
Uninstalling n++, deleting EVERY registry entry & folder containing 'notepad++' (except one, from whose string I removed ";notepad++.exe"), then reinstalling n++ made VS stop opening notepad++.
Now it opens the default web-browser again.
[edit]
Note for anyone else out there who ends up with this specific and bizarre problem:
It would be worth a shot to try changing the "Browse With..." setting in VS, by r-clicking on Default.aspx to "Internet Explorer". My list included Notepad++ as an available internet browser.
This might be a better solution than the previous, if it does in fact work.
I didn't know this setting would allow Notepad++ as an option until I had to set it back to IE again after all this, and that may have been the problem all along. Apparently, VS just changes this setting sometimes. How or why N++ got put in as an internet browser is completely beyond me, but I did myself the favor of 'Remove'ing NotePad++ from the list, and you may wish to do the same.
Again, I'll never truly know whether or not I nuked everything when I could have changed a single setting that got mysteriously reset, but may this [lesson?] at least be recorded for posterity.
[/edit]
It took all of that to figure out that it [was?] a bogus registry entry somewhere that [may have been?] modified by the hotfix; a registry entry that neither notepad++ nor visual studio 2010 ultimate would clean up on uninstall or replace on reinstall
Which was it? I have no idea. Like I said, I didn't even use n++ this week until VS started opening it for me, and the only change I made was to install that hotfix.
I'm really confused about this problem, and I'm pretty new to Flex. Basically, anything I try to build with mxmlc fails to run now, giving me the above three errors depending on what I do. It was working 30 minutes ago, I've been spending that time trying to figure out what has changed. I redownloaded the Flex SDK, cleared my assetcache, have cleared Firefox's cache. (I'm using Linux.) Even if I compile with -static-link-runtime-shared-libraries=false, since it seems like #2048 is a RSL problem, it still refuses to run.
Another strange thing, if I keep
<policy-file-url>http://fpdownload.adobe.com/pub/swz/crossdomain.xml</policy-file-url>
<rsl-url>textLayout_1.0.0.595.swz</rsl-url>
in my flex-config file, then firebug tells me that my swf file is trying to access a copy of that in the app's folder, giving error 2032. And if I stick the one I have in frameworks/rsls/ then it gives me error 2046. I don't know how it could not be properly signed, unless Adobe magically changed a signature and didn't update their flex SDK.
Any help will be appreciated.
On Linux I sometimes get these errors. It seems that the Flash Player cache sometimes get corrupt. When I delete the asset cache I then have to reboot in order for things to work again. Not fun. I filed a bug a while back but without having a consistent way to recreate the corruption I can't help them reproduce the issue. Please file a bug if you have a consistent way to reproduce the issue.
Okay, more weirdness. Simply restarting Firefox seems to have allowed the applications to work again. Facepalm
Today I experienced that problem in one browser but not in other. I have Ubuntu 10.04 and in google chrome 6 I received error #2046. In FireFox and Opera everything worked well. The problem has been solved when I reloaded my chrome browser.
This is an off the cuff answer, maybe not correct, but I encountered a similar issue recently and discovered that the issue was that our app was not compiling the Flex libraries into the SWF. Because of this, in some cases the Flash player would for whatever reason decide that the cached Flex libraries (.swz files, aka Runtime Shared Libraries or RSLs) were incorrect versions and so would refuse to load them, giving similar errors without explanation. These cached libraries are separate from the browser cache, they are cached for the whole OS. You could try explicitly linking the Flex libraries into your SWF to troubleshoot the problem. If it goes away, that's a useful clue.
