Hi Mousegeezer, Yahoo should not be blocked.

Are you starting from their home page?

https://www.yahoo.com/

Does this search link work:

https://search.yahoo.com/search?p=firefox

If the problem is with a different search address, what is the URL that isn't loading?

No, the link says unable to connect. I am using yahoo as my home page which is set up on my firefox browser. But, anything I search for comes back as unable to connect. I uninstalled firefox and reinstalled it and got the same result. If I use the firefox browser and don't go into yahoo searches perform correctly.

Thanks for your help. I really think this related to a firefox update that popped up today.

https://www.yahoo.com/ this is the url of the failed search

Nothing wrong with the site. Can always check using this http://downdetector.com/

There seems to be a issue that only affects users who have turned off cleartype font rendering within their windows settings. so a workaround for the moment would either be to turn cleartype back on or disabling hardware acceleration in Firefox: Firefox's performance settings https://support.mozilla.org/en-US/kb/performance-settings It is a issue on some sites. If after trying and it works please inform us.

If it does not work can try this : uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files , C:\Program Files(x86) & C:\ProgramData Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :

• https://support.mozilla.org/en-US/kb/export-firefox-bookmarks-to-backup-or-transfer

Reinstall with Current Release Firefox 59.0.1 with a Full Version Installer

Please let us know if this solved your issue or if need further assistance.

I'm trying to really understand this.

Scenario 1:

Home page is https://www.yahoo.com/

Type a query into the search box in Yahoo and submit the search and get an error. What is the address in the address bar at that point, the address of the page that won't load?

Scenario 2:

Enter a search into Firefox's address bar or search box and submit it, and you get some search results. What is the address in the address bar at that point -- is it a Yahoo page? (Of course, if the results are on Bing, Google, or some other site, it doesn't tell us why Yahoo isn't working from their own home page.)

Do a malware check with several malware scanning programs on the Windows computer.

Please scan with all programs because each program detects different malware. All these programs have free versions.

Make sure you update each program to get the latest version of their databases before doing a scan.
