Up until the latest updates a week or two ago, UPS tracking worked fine. However, with version 100.x, UPS stopped working. All is get is the error message, "We are unable to complete your tracking request at this time. Please try again later.". I tried other older tracking numbers that I know are good, and the same error. However, UPS tracking using Chrome or Explorer/Edge works fine.

I could blame UPS, but both Chrome and Explorer/Edge does work.

Apparently, Firefox is sending a (buggy) request that UPS doesn't like.

Thanks, Bill

I think you should get the their smart phone apps and login those will do better in tracking in real time faster.

Same issue here. Safari works fine but Firefox hasn't worked in weeks. I updated today hoping that would solve it but no luck. It's not just UPS either, I've been having issues with other sites as well.

This issue can be caused by corrupted cookies or blocked cookies.

  • check the permissions for the domain in the currently selected tab in "Tools -> Page Info -> Permissions"

Clear the Cache and remove the Cookies for websites that cause problems via the "3-bar" Firefox menu button (Settings).

"Remove the Cookies" for websites that cause problems:

  • Settings -> Privacy & Security
    Cookies and Site Data: "Manage Data"

"Clear the Cache":

  • Settings -> Privacy & Security
    Cookies and Site Data -> Clear Data -> [X] Cached Web Content -> Clear

You can remove all data stored in Firefox for 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 for this domain like history and cookies and passwords and exceptions and cache, so be cautious. If you have a password or other data for 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 for that website will be saved once again.


If clearing cookies doesn't help then it is possible that the cookies.sqlite file in the Firefox profile folder that stores the cookies got corrupted.

  • rename/remove cookies.sqlite (cookies.sqlite.old) and when present delete cookies.sqlite-shm and cookies.sqlite-wal in the Firefox profile folder with Firefox closed in case cookies.sqlite got corrupted.

You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page (Root directory).
