Is Google Burying Firefox With User Agent Strings?

Next, I visited 6 different Google services, in a row, 3 times. Gmail, Adsense, Analytics, Google Plus, YouTube, Drive and Google Music. No errors yet, but this this is definitely not enough data to base any wild claims on.

Google Chrome

Now that I’m back in Chrome, let’s try the same thing. Nothing unusual here. I haven’t changed my user string to anything other than the default and I haven’t even signed into Google Chrome. I visited the same 7 Google services 3 times in a row and didn’t get any errors at all. Now, let’s try and actually prove something.

I installed User-Agent Switcher for Chrome and added my user-agent-string from Firefox.

Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:12.0) Gecko/20100101 Firefox/12.0

I tested it to make sure it was reporting properly at whatsmyuseragent.com. Sure enough, whatsmyuseragent reports that my browser is properly reporting the Firefox user agent string.

I ran into trouble immediately.

Gmail refuses to load! i refresh the page several time, but I never actually get anywhere. Let’s keep going. My next error happens when trying to access Google Adsense.

ERROR: Possible problem with your *.gwt.xml module file. The compile time user.agent value (gecko 1_8) does not match the runtime user.agent vaule (safari). Expect more errors.

Now I will be fair here. This error is crystal clear. It seems that Google services such as Adsense are able to detect that it is indeed being accessed from Chrome, regardless of the user agent being broadcast. I will say that the “expect more errors” is a little harsh though…

My troubles persisted. I opened up 4 tabs and ran a Google search for “anything”. Each time I was greeted with a fully loaded blank white screen. Given the nature of the error above, it will be difficult to prove anything from the Chrome side of the fence. However, one thing is still glaringly clear…

Firefox now works perfectly with a Google Chrome user agent string.

Stop using the evil CHROME. I am on Firefox Nightly. I firefox is again evolving to be the top browser. It is as fast as chrome and with much much more customization and developer tools. Although I do not recommend you to use Nightly, But for I can only say that it is always better for us and the web to use open-source browsers like Firefox.

Few people think Chrome is open-source, but it is not. It is based on chromium which is open-source but it is’nt open-source.

  So don’t use Chrome or Firefox, use Chromium (this is what I do) ;P

This sounds bad, if true. However, I’m using Firefox/Iceweasel and Google services a lot, and can’t say I’ve noticed the mentioned error.

Sure enough, they try to get me to switch to Chrome in other ways; for example by only letting me view google docs offline in Chrome, but that’s less creepy (but not good).

Even so, I’ve never been comfortable with giving them (Google) control over my entire web eco-system, so I’m sticking with Firefox, despite Google trying to entice me to do otherwise

The message you get from AdSense is a generic message from the Google Web Toolkit bootstrap script – the script that loads all GWT applications.

Check out the last method in this class http://code.google.com/p/google-web-toolkit/source/browse/trunk/user/src/com/google/gwt/useragent/client/UserAgentAsserter.java?spec=svn10943&r=10943

GWT compiles an optimised version for different browsers, and you’re confusing it by telling it lies with your user agent switcher

I have noticed this problem for the past couple weeks. About the same time as I replaced my router and thinking that might have caused the problem.

I do NOT use Google Chrome, firstly as I really dislike the interface, and it is getting too annoying Google trying to shove it down my throat. For those reasons, I will NEVER use Chrome. Yes, I use Gmail and Google search, but that is by MY choice, not theirs.

As an open source enthusiast you should not be slavishly using Google products in the way you do. For example, having a policy where you will only buy a Nexus Android device is simply rewarding Google for using a non-open development model for Android. By buying a non-Nexus device from one of Google’s less preferred partners you are encouraging a more open Android into the future.

The same goes for Firefox vs. Chrome – you shouldn’t even be considering Chrome! Similar to your switch from KDE to Ubuntu – WTF???????

  I can’t make any sense of what you are trying to say here. Care to explain?

I use chromium, and I got a lot of those error message lately. So I try Firefox, and got the same problem. So, I think neither the browser nor user agent are the problem.
Paul Wujek

I use Firefox and/or Chromium on Ubuntu 12.04 and have never seen the errors you’re getting.

I use Google search, gmail, and Google Docs.

Something in your environment/configuration is to blame.

You may be running into a compatibility issue with the new SPDY that Firefox just added and the Google servers are almost the only servers that support it. It may explain the strange effect. Google has no reason to target Firefox – they are Firefox’s main source of revenue and they work together on many projects. Those seeing evil should probably clear some dirt from their glasses…

  SPDY is on for Fx13, not Fx12:
  
  https://wiki.mozilla.org/Platform/Features/SPDY
  
  Although, I’m personally not running into any problems with it set to on while running Fx Nightly. Which is what I’ve been using for over a year now.

    SPDY is in Firefox 12, just not turned on by default.

Same here under Ubuntu 12.04 from an IPv6 network (maybe it can help ?), lots of errors on the first request of my G.Apps mailbox.
Now on W7, no more errors.
dvhh

My guess would probably on how google is enabling the SPDY protocol based on user agent sniffing and have not yet enabled it for firefox (or use a buggy one for firefox). I would be curious to see the test on other third party browsers (IE, Safari, Opera, lynx, links …..).

Google products are not using HTTP with Chrome but SPDY, Their own protocol, More original that GTTP right? It is is among proposed protocols to make HTTP 2.0 (see IETF)

The only other (mainstream) browser that uses SPDY is Firefox.

It seems, it does it in some wrong way.

NB : I use Ubuntu 12.04 too and I just launched Firefox to test what you said. I have no issue and I can’t reproduce your claim (Connecting from France)

I’ve been using Ubuntu for years with both Chrome and Firefox and I’ve never seen issues with Firefox getting higher connection resets. I’m happy to ask people at Google to dig into this report, but I have to say this sounds completely off base to me. Google wants our website and services to work very well with with Firefox. Are you seeing this issue only with Ubuntu 12.04?
- http://profiles.google.com/deanhowell2 Dean Howell
  
  Matt, yes I’ve only seen the issue with 12.04. I have a virtual machine running Windows XP, so I might try to reproduce it there.
  
  We would be delighted to hear what Google has to say in regards to this, and we would also be happy to redact any outrageous claims. What this article represents is merely my observation, which has gotten a lot of attention.
  
  Thank you Matt!

What version of Firefox are you using? Firefox is implementing support for SPDY, which could potentially account for networking issues connecting to Google but not other sites if there’s bugs in that particular version of Firefox (as Google is one of very few sites currently using SPDY). AFAIK SPDY is enabled in FF13 and above. Not sure what version you’re using.
Ian Fette

Also, if you can reproduce, any chance you can open a bug (bugs.chromium.org/new) and attach a wireshark trace?

Here’s an odd one for you: I recently installed Xubuntu 12.04 in which Firefox is the default. I added Chromium, tried both on your site, and got the Connection Reset error both times. Didn’t get it with any other site. I’m not making this up to troll or anything – really happened exactly that way!

I’ve never had the poster’s issues, however, I did find wierd issues with Google maps. (note: i use classic mode, not webgl mode)

I found out its pretty slow in Firefox, specially in satellite mode. I tried in Chrome and it was smooth as butter.

I wondered for a while and decided to do what he did back then, so switched Firefox’s user agent to Chrome.
Not everything worked but it was butter smooth. Switched to FF 4 UA.. everything worked and still butter smooth. Anything above, it lags just a little.

Doing the opposite doesn’t work, it breaks the site (yeah HTML5 is SO standard uh?)

Now it might be Firefox and a function gmap uses in the new Firefox versions, or it might be Google, but that’s still odd. Google MUST have noticed if they started using a new function, and since the site functionality is identical, it’s still a bad move from Google.
Chris Pearce

If you load up “about:config” in your URL bar, and search for the “network.http.spdy.enabled” pref, what is its value? If it’s “true”, then you could be running into bugs in the SPDY implementation. If you set it to “false”, does the problem go away? Checking/doing this will enable you eliminate that possibility at least.

Try this: Pin Gmail to Firefox +12, open a ran manager and see how it exponentially increase the memory consumption of Firefox! Do the same thing on Chrome and all stays under control… Weird? Coincidence?
- http://linux-blog.org devnet
  
  Mine had the reverse effect with Chrome finally crashing my entire system while Firefox nightly had 0 problems and ran with lower memory. Weird eh?

    That’s weird…

I would guess they’re doing some custom Javascript that depends on your browser. Then a simple bug in the Firefox-specific code would explain it. I do use Firefox and haven’t had these issues at all so it might just be something specific with your setup.

I am not an I T person but a simple(ton) user and cannot carry out any of the tests to prove or disprove that Firefox is being throttled.

But I am very sure that ‘fear of the Orwellian future they are capable of realizing for us all’ is not unfounded. I have also watched with trepidation the rise and rise of google and their diversifications (which are required to expand their businesses). It should not happen that ultimately their dominance strangles us all.

I’m actually having the exact same issue on Win 7 Pro with Firefox 12. I use both Firefox (work email and apps) and Chrome (personal email and apps) actively and have no issues with Gmail in Chrome, but I am continually having to do forced refreshes in Gmail on Firefox (even with all Add-ons disabled in power mode). This just started within the last 10 days. Never had issues before. It’s actually made me switch back to Outlook as my primary email client for my work email.

  Looks like this issue has been cleared up. FF 12.0 with SPDY enabled is now performing almost as well as Chrome again.
SomeGuest

Can’t reproduce. Neither on Ubuntu 11 nor on Ubuntu 12. Both Firefox and Chrome work equally well (except for Firefox having an insane memory consumption).
