The past couple weeks while I'm trying to use Firefox on windows 10 desktop, it will out of the blue come up with No Internet Connection. Sometimes it happens within 5 min. or up to 30 min. On the rare occasion I am able to view my new emails & links w/o a problem. The automatic update was done a few days ago but didn't really seem to make that much difference. The lights on modem continue green & router is orange for normal. So I know it is not my service provider. Besides I can use internet on Edge w/o a problem. However I have used Firefox for years & really like it. I'm not much of a techie person, so simple explanation/fix on my issue would be much appreciated. Thanks in advance for your help.
