I have hit what appears to be a "YouTube TV" (vs YouTube) buffering problem. It happens only with Firefox on my PCs. After a few seconds to a minute of playing a TV program or movie, the video/audio stops with a spinning arrow. If I previously had turned on "stats for nerds" to monitor this, I can see when network activity stops and the buffer then eventually gets exhausted.

This does NOT happen when running YouTube TV on my TVs or on my iPhone. Probably more significant, it does NOT happen with YouTube TV under either Microsoft Edge or Google Chrome on these PCs. If I run Firefox in Troubleshoot Mode, i.e., no add-ons, extensions, etc., the problem still exists, so it is not just some rogue add-on, but is related to Firefox itself. The problem appears to be only for "YouTube TV" on Firefox since, for example, videos played from YouTube (vs "YouTube TV") do not have the problem under Firefox.

I tried rebooting my router as well as the PCs. The problem still existed. The PCs are high speed and the internet connection is fiber optic. One of the PCs is connected by Ethernet; the other is wireless. Download/upload speeds are over 900 Mbps on the Ethernet PC. I have not seen slow network indications on anything except this "YouTube TV" with Firefox mixture. Hardware does not seem to be the issue.

Apparently the problem is software. I also tried temporarily disabling my antivirus/firewall software. No change. I'm running Windows 10 version 21H1 and Firefox 88.0.1. I'm new to YouTube TV; although most of my viewing with it has been done on TVs, I don't recall seeing this problem in my PC tests a month or so ago.

This weird! when I export my current bookmarks to html to a thumb drive, Firefox exports and old list, not the current list! I can add a bookmark, export the list, the new bookmark shows, but the list is not the current bookmarks. this new list contains bookmarks that I had deleted, and are not in my current bookmarks!

How can I put bookmarks in the toolbar at the top where it used to be? When I bookmark to the toolbar I can omly find them by clicking Bookmarks and clicking on toolbar in the drop down.

In recent times, after I've been browsing for about 20 or 30 minutes, Firefox becomes very very slow to respond. Simultaneously it coincides with a similar slowdown over the entire computer - in finder and with other open programs. If I close Firefox (which takes several minutes to complete) the slowness of finder and the open programs disappears. The slowness never happens unless Firefox is open. I've tried Chrome and haven't had the same issue.

What might be causing this delayed slowness and how do I solve it?

I asked a simple question: "What is VPN?" I got dumped to pay for an Apple answer. I already have Apple Care. I just made a $15 Firefox donation. I have just signed up for the New, Improved Firefox after a lengthy absence from Firefox for being unhappy with the program. NOW... You ask ME to be nice! ? ! - Adrienne Pollak

When I access BambergerTrivia.com, my web site on Weebly, i get the warning "Warning: Potential Security Risk Ahead" that is not true. How do i get rid of it? Dave Bamberger

This happens far too often, in the course of 9 months or more frequently. What is going on Firefox? v88.0.1 Windows 10

Constant script errors that freeze whatever program I am in, regardless of the option I choose - the popup no longer gives me a WAIT or STOP IT. The box comes up that says DON'T ask me about this again.

I do not want to copy passwords, more than anything, should I create a new profile. I do not want to deal with replacing or losing the file. When I attempted to load two other profiles over the last two days, both times FF crashed. I gave up.

I am NOW in Safe Mode and without errors, and it's hard to know which app is causing the problem.

Is there a new addon that will back up Firefox these days?

Suggestions? Seriously, FF seems to be a whole lot more trouble these days than she is worth.

Thank you.

I try to save bookmarks but cannot find them. Please tell me what are the options & where are they saved? Thanks. I have a Dell laptop with Windows 10. Bernie

Sure miss the Firefox snipping tool. I keep reading it was not A Firefox tool but Windows and that's not true. It was not available on Edge but always under the three dot of the URL bar. Why was it removed? I rarely want a screenshot, just a snip of an area.
