Google Chrome and Mozilla Firefox hang when trying to upload or download a file. I suspect an NSS problem

In both Mozilla firefox and Google Chrome, when I attempt to upload or download a file (including a photo), the browser hangs. I can clear the hang with kill -2 PID but I'd rather not do that. When I start chrome, I get the following error message: [1320750:1320844:1205/224205.121619:ERROR:nss_util.cc(349)] After loading Root Certs, loaded==false: NSS error code: -8018 It isn't clear to me that this is the problem, but there are no other error messages or indications of a problem that I can find, so this is where my investigation went..

I did a little googling (ironic, ain't it)(hint to the wise: when searching, exclude the - in -8018. The - means "exclude this word" which is the opposite of what we want to do). I found Error at startup (nss_util.cc(349)) with the AppImage version 1.1.1 which referred me to Error initializing NSS when trying to launch Google Chrome. It suggested installing libnss3-nssdb, which I tried to do and failed: apt can't locate package libnss3-nssdb. However, I did reinstall all of the libnss3 packages and apt picked up libnspr4-dev automatically. That cleared the error message from nss_util.cc but did not solve the problem about hanging on upload or download.

Now, in thinking about this problem a little more, there is something that I notice that I do not see. When I attempt to upload or download a file, a file selector dialog box should open and allow me to select the name of the file to upload from or download to. I don't see that. Could that be the issue? How would I go about troubleshooting that?

I am running the 5.15.0-52-generic #58-Ubuntu SMP kernel. I have Ubuntu 22.04.1 LTS. Mate 1.26.0, lightdm 1.30.0. I am running Firefox 107.0.1 and Chrome 108.0.5359.94.

Thank you

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
