This website loads on my Firefox program fine.

Many site issues can be caused by corrupt cookies or cache. In order to try to fix these problems, the first step is to clear both cookies and the cache. Note: This will temporarily log you out of all sites you're logged in to. To clear cache and cookies do the following:

1. Go to Firefox > History > Clear recent history or (if no Firefox button is shown) go to Tools > Clear recent history.
2. Under "Time range to clear", select "Everything".
3. Now, click the arrow next to Details to toggle the Details list active.
4. From the details list, check Cache and Cookies and uncheck everything else.
5. Now click the Clear now button.

Further information can be found in the Clear your cache, history and other personal information in Firefox article.

Did this fix your problems? Please report back soon.

Try Firefox Safe Mode to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.

(If you're not using it, switch to the Default theme.)

• On Windows you can open Firefox 4.0+ in Safe Mode by holding the Shift key when you open the Firefox desktop or Start menu shortcut.
• On Mac you can open Firefox 4.0+ in Safe Mode by holding the option key while starting Firefox.
• On Linux you can open Firefox 4.0+ in Safe Mode by quitting Firefox and then going to your Terminal and running: firefox -safe-mode (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
• Or open the Help menu and click on the Restart with Add-ons Disabled... menu item while Firefox is running.

Once you get the pop-up, just select "'Start in Safe Mode"

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article for that.

To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.

Please report back soon.

Thanks for reply.

I have tried clearing cache and Cookie for my Firefox , But this will not cause this issue. This issue is specific to Mac and Firefox 25, not other OS.

If i remove my webfont from stylesheet , I'm able to see My website. Its specific to Web font as well

Mac Firefox 25 crash report here

we have removed font-face and font-family from style sheet and used google font api.

<link href="//fonts.googleapis.com/css?family=Karla:400italic,400,700italic,700" rel="stylesheet" type="text/css"> <style>

   body {font-family:"Karla"; }

</style>

We are glad to here that you have solved your Firefox issue.
Thank you using the Mozilla support forum.
We hope that you will continue to browse with us here on Mozilla Firefox.

This seems like a workaround as opposed to a solution. Is the underlying problem, which started with Firefox 25, being addressed at this time?

This problem is not present in upcoming version. it may be addressed on upcoming version.

I wrote about this in another thread, but in case anybody comes a-searchin', I believe this issue is related to:

https://bugzilla.mozilla.org/show_bug.cgi?id=906704

It would appear that the combination of absolute positioning, "synthetic" bolding, web fonts, and rotating triggers an infinite loop in Firefox 25. I was able to create a temporary workaround by just removing the bolding on my site.

The issue is supposed to be fixed (as OP mentioned) in the upcoming version.

Same problem with FF 26 on OS X 10.9.1

Funny thing is, it's not the CSS that actually hangs Firefox, it's the rendering of the (a) font. Pages that don't make use of that specific font work fine.

Disabling gfx.downloadable_fonts.enabled did not help.

Page works fine in IE and Chrome.
