Sources error message
In Firefox, when viewing the person page, tab to sources, the sources are listed, but when you click on the source to view it, you get an Oops error message. If you go to the side drop down (three dots) and click on sources, the source is viewable there.

No "oops" error message here on Firefox when viewing a source from the person page.
You might try clearing your FamilySearch cookies in Firefox at www.familysearch.org/cookies1
Like Áine, I'm not experiencing any trouble accessing sources, neither on profile Sources pages, nor using the Sources tool/side-panel. (Firefox current, Win10.)1

Does deleting cookies slow down computer?
The cache can also cause issues when viewing new versions of previously visited web pages. Deleting the cache and cookies data regularly helps to troubleshoot, helps to increase the loading time of web pages, loads new versions of web pages and increases the performance of your computer.
Plus it always good idea to run a Latest Virus Protection to encase that cause the issue to as in encase you have like virus or malware or other things to.
