i set yahoo mail as a homepage. start firefox v28 and the screen goes blank, nothing shows in the addr bar and it just sits with the spinning green icon. no problems until i moved to v28. i often have issues with flash player hanging and created a dos bat file to kill it but that is not what seems to be happening with yahoo. pretty much everything else works. FF freezes but killing the plug in releases it. the newer versions of FF seem more flakey than the older ones. thanks for your help

How do you kill the Flash player plugin using a BAT file -- are you killing an Adobe Flash exe or Firefox's plugin-container.exe?

You can start up Firefox to a blank page using the Run box on the Start menu, with this:

firefox.exe "about:blank"

Hopefully that will at least get you in. Then, for Yahoo mail, make sure to access your mailbox through the Yahoo home page (or AT&T Yahoo home page, etc., as the case may be). And:

When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.

(1) Bypass Firefox's Cache

Use Ctrl+Shift+r to reload the page fresh from the server.

Alternately, you also can clear Firefox's cache completely using:

orange Firefox button (or Tools menu) > Options > Advanced

On the Network mini-tab > Cached Web Content : "Clear Now"

If you have a large hard drive, this might take a few minutes.

(2) Remove the site's cookies (save any pending work first). While viewing a page on the site:

  • right-click and choose View Page Info > Security > "View Cookies"
  • Alt+t (open the classic Tools menu) > Page Info > Security > "View Cookies"

In the dialog that opens you can remove your Yahoo cookies individually.

Then try reloading the page. Does that help?


To rule out extensions as a possible culprit, could you try the site in Firefox's Safe Mode? That's a standard diagnostic tool to deactivate extensions, some advanced features, and some custom settings. More info: Diagnose Firefox issues using Troubleshoot Mode.

You can restart Firefox in Safe Mode using

  • Help > Restart with Add-ons Disabled

Note: Flash and other plugins still run

After Firefox closes, a small dialog should appear: click "Start in Safe Mode" (not Reset)

Any difference?

Of course, I would be remiss if I did not point out:

Mozilla has disclosed security flaws in Firefox 28 and 29 that have been fixed in Firefox 30. Is something holding you back from upgrading? Something not addressed by this article: How to make the new Firefox look like the old Firefox?

Please let us know so we can suggest solutions or workarounds. Hundreds of bugs are fixed in each release, and it may not be possible to solve some bugs in Firefox 28 without upgrading.

It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access to internet for Firefox and the plugin-container process and the updater process.
