I never had an issue with YouTube, including just now.

Many site issues can be caused by corrupt cookies or cache.

• Clear the Cache and
• Remove Cookies

Warning ! ! This will log you out of sites you're logged in to. You may also lose any settings for that website.

• Cookies; Delete cookies to remove the information websites have stored on your computer {web link}

• Cache; How to clear the Firefox cache {web link}

If there is still a problem, Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Did this help?

While you are in safe mode;

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.

Is this only an issue with the YouTube website?

You can remove all data stored in Firefox from a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -> Show All History" or "View -> Sidebar -> History").

Using "Forget About This Site" will remove all data stored in Firefox from this domain like history and cookies and passwords and exceptions and cache, so be cautious. If you have a password or other data from that domain that you do not want to lose then make sure to backup this data or make a note.

You can't recover from this 'forget' unless you have a backup of involved files.

If you revisit a 'forgotten' website then data from that website will be saved once again.

You can check the connection settings.

• Options/Preferences -> General -> Network: Connection -> Settings

If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.

See "Firefox connection settings":

Everytime I try to go to Youtube after a long wait for Firefox to connect to the site I get this error message: Unable to connect Firefox can’t establish a connection to the server at www.youtube.com. The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer’s network connection. If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web. I am able to load all other sites on Firefox except Youtube. I am also able to load Youtube on Safari too. How do I resolve this problem?

I don't know what happened but when I tried to go to Youtube this morning expecting the same issue I reported on yesterday, it connected to the site. Therefore my issue is solved! How? I don't know. I am just grateful that it is.

Give it a few days. If the problem does not return, Please flag your last post as Solved Problem so others will know.

If it does, let us know.

The problem resolved itself. How? I don't know but it did. I don't know how to flag this "Solved" but the problem has solved itself. Thanks for your help.

Glad to help. Safe Surfing.
