I have downloaded Firefox update 17.0.1 on my windows 7 Home Premium 64 bit. Now my yahoo mail page

has strikethroughs on tabs "Check mail, go,delete,reply, spam,forward, spam, move, actions tabs across top of email.

Also, the check box to the left of the email is not showing up. The only way to delete an email is open it up and use delete key. I cannot do a quick sweep of checking multiple boxes at left of email and delete multiple emails at 1 time. I opened yahoo email in IE and switched between att classic mail and att new mail and the pages look fine. So, it seems to be something with Firefox. All plugins are up to date.

You might already have tried this, but just in case... 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.

(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")

(2) Remove the site's cookies (save any pending work first) using either of these. 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"

Then try reloading the page. Does that help?

Thanks for your reply. I did each of the steps you outlined, and nothing has changed on the email. I did try switching to ATT Classic Mail and have the check boxes back, and the tabs are not struck through. However, there is text over text. Any ideas?

I don't know whether you use the zoom feature, but there are two modes: text only zoom and full zoom. Full zoom proportionally resizes everything, but with text only zoom, words can overflow the space allowed and break the layout. To check:

Alt+v (opens the classic View menu) > Zoom > uncheck Zoom Text Only


You may also want to check whether an add-on is at fault. A standard diagnostic is to use Firefox's Safe Mode, which is described in this article: Diagnose Firefox issues using Troubleshoot Mode. Does that make any difference?

If you have increased the minimum font size then try the default setting "none" in case the current setting is causing problems.

  • Tools > Options > Content : Fonts & Colors > Advanced > Minimum Font Size (none)

Make sure that you allow websites to choose their fonts.

  • Tools > Options > Content : Fonts & Colors > Advanced > [X] "Allow pages to choose their own fonts, instead of my selections above"

It is better not to increase the minimum font size, but use an extension to set the default page zoom to prevent issues with overlapping text.
