Hello,

Try Firefox Safe Mode to see if the problem goes away. Firefox Safe Mode is a troubleshooting mode that turns off some settings and disables most add-ons (extensions and themes).

(If you're using an added theme, switch to the Default theme.)

If Firefox is open, you can restart in Firefox Safe Mode from the Help menu by clicking on the Restart with Add-ons Disabled... menu item:


If Firefox is not running, you can start Firefox in Safe Mode as follows:

• On Windows: Hold the Shift key when you open the Firefox desktop or Start menu shortcut.
• On Mac: Hold the option key while starting Firefox.
• On Linux: Quit Firefox, go to your Terminal and run firefox -safe-mode
  (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)

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 to find the cause.

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

When you figure out what's causing your issues, please let us know. It might help others with the same problem.

Thank you.

Clear the cache and cookies only from websites that cause problems.

"Clear the Cache":

• Firefox/Edit > Preferences > Advanced > Network > Cached Web Content: "Clear Now"

"Remove Cookies" from sites causing problems:

• Firefox/Edit > Preferences > Privacy > Cookies: "Show Cookies"

The Problems with email and how to find help article I posted says this:

If you're having a particular problem with your webmail only while using Firefox but not in other browsers, see Websites look wrong or appear differently than they should for common solutions.  

Check out those common solutions if you haven't already. The first one is to Clear the cookies and cache.

Clearing cache/cookies worked in this recent thread:

• http://ubuntuforums.org/showthread.php?t=2184743 [SOLVED] Recent Firefox/Hotmail Trouble

If you find a solution on the ubuntu forums, please post back so that others can benefit. Good luck.

You can check for problems with preferences.

Delete a possible user.js file and numbered prefs-##.js files and rename (or delete) the prefs.js file to reset all prefs to the default value including prefs set via user.js.

• http://kb.mozillazine.org/Resetting_preferences

Create a new profile as a test to check if your current profile is causing the problems.

See "Creating a profile":

• https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
• http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues

If the new profile works then you can transfer some files from an existing profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over the problem.

Thanks for posting back. You wrote,

I found a recent question here describing a similar issue (but no solution), http://askubuntu.com/questions/407582/web-based-hotmail-acct hotmail acct accts log in fine but am unable to open mail, compose mail, etc yahoo mail,gmail work fine Useing Firefox 25.0.1 Ubuntu 12.4 LTS ppc,

In case it helps you or anyone else, I also found this older thread on a debian forum that mentions hotmail problems on a Mac Powerbook G4 PPC suggesting the "User Agent Switcher" Firefox addon: http://forums.debian.net/viewtopic.php?f=20&t=63740 Hotmail seems to recognize PPC systems as embedded- not all are- and categorizes them with mobile devices.
... I also found this thread which also indicates a possible "user agent" issue, http://hackaday.com/2011/07/24/hacking-14-year-old-power-pc-mac-back-to-life/ ... the PowerPC architecture comes up as PPC, which Hotmail interpreted as PocketPC which caused Hotmail to present a severely reduced login page

Bottom line, if you want to try Hotmail on Firefox again, your best bet might be the Hotmail forum which is now http://go.microsoft.com/fwlink/p/?LinkId=260870

In any case, I'll mark your last post as resolving the issue, for now. If you still need help with Firefox, please post back.

You can try to set the user agent to a more generic version for Linux (Linux i686).

• Mozilla/5.0 (X11; Linux i686; rv:25.0) Gecko/20100101 Firefox/25.0
• User Agent Switcher: https://addons.mozilla.org/firefox/addon/user-agent-switcher/

Do not forget to update the user agent when you update Firefox.
