Not just every day, but I just updated and restarted, only to have another popup window ask me to download the latest version, as the update I just did, was loading!! WTF? Why didn't it update me to the most recent version the first time?? Since I had a lot of windows open, it took a good long while, having to go through the download & restart process, twice in five minutes.... does this make any sense, whatsoever?
I have Firefox 78.15.Oesr. I got a popup prompt to update my Firefox browser. When I manually opened my Firefox Browser "About Firefox" it told me that my version was up to date. I suspect that someone may be mimicking Firefox with malicious "update" software. Be careful about update prompts.
