Hi,

Please try a Ctrl + F5 refresh. This helps to bring in the page contents afresh. You can also consider the Reset Firefox feature via Help (Alt + H) > Troubleshooting Information.

(To revert to the previous profile, close the new profile, start Firefox and choose the *.default profile. While the Profile Manager is open, you can also delete the newly reset profile (the one containing random numbers)).

Profiles Howto

If you have security software (antivirus, firewall etc.) installed, you can try deleting all existing instances of Firefox and related files in all the different configuration areas/modules of the security software. Instead create new allow/trusted rules for Firefox + its related processes. Even otherwise the security software may also ask again when Firefox is started and you can try to allow/trust at that time. Please see this.

In what way is the text different?

Which encoding is used for those messages?

Is that Unicode or a specific Windows or Western (ISO-8859-xx) encoding?

Thanks Dumdidadida, but your advice doesn't work. Cor-el I am using ISO-8859-1 as with my others Internet browser.

When I use my Yahoo email account with other Internet browser and/or using any other computer, I see the right format. If I use any other computer to read my Yahoo email account and use Firefox I get the wrong format.

Please see the attachment

TIA

Is the full text in the page source?

• Firefox > Web Developer > Page Source
• Tools > Web Developer > Page Source (Ctrl+U)
• Right-click on a web page to open the context menu and select View Page Source

There may be a font problem if Firefox doesn't display the text.

You can also try to use the build-in Inspector to check the page code.
