My system is Firefox 79, Windows 10. Lazy loading is supported in Firefox since version 75: https://caniuse.com/#feat=loading-lazy-attr

I found that this works on Firefox for lazy loading of images. However, YouTube embedding in an iframe, it doesn't work. I ensured that the video is long way below the fold. Even then, the iframe is loaded upfront. This is the HTML for the iframe:

<iframe loading="lazy" src="https://www.youtube.com/embed/iQBat7e0MQs" allowfullscreen="" width="480" height="270"></iframe>

On Chrome, lazy loading works as expected for the same web page (on my localhost).

I'm using Firefox 79.0 on Win10 x64. When I'm searching on Google, Facebook or Youtube, there is a 10-20 seconds delay between my input and its display in search field, and it's displaying symbols I entered at 1 symbol in 1-2 seconds. After around a minute the delay cuts to minimal and I can use the search normally (but by that time site is already responding to the earlier input which sometimes can be in wrong keyboard layout or misspelled because I didn't see what I was typing until 1 minute after I typed it). I don't have this problems at the websites that are not Google-related, also I don't have it in other browsers. I've tried restarting Firefox (obviously, as this problem persists for weeks now) and/or clearing cache, didn't help.

Hello,

I've experienced a blue screen of death on my machine as listed below, which seems to point that Firefox.exe is the starting point of the BSOD.

I had around 8 tabs open at the time of which 2-3 Twitch.tv channels, Private mode tabs with several websites with a variance of content-typed on them.

However, I had these open in the background while I was playing a game and at some point my computer just rebooted.

It hasn't happened another time (yet) and it is the first time I've had a BSOD for quite some time so it kind of scared me.

I had Hardware Acceleration turned on and Content Process limit was set to 8(Default).

The Nvidia drivers I have installed are: 451.67 (09-07-2020)

Hello

Such web pages after loaded, show the video embeded window in white with in the middle written : "Click to activate Adobe Flash Player"

It is on Linux Mint 19.3 with Firefox 79.0 , FFMPEG is the last version proposed by the depositories : 7:3.4.8-0ubuntu0.2 Opera show the same issue So I must use Google Chrome for these websites Linux Mint 19.3 installation USB key is not affected

If I accept Flash to display these video, the quality is too bad, compared with HTML5, it is like some 240p enlarged to 1080p

since a recent windows update, firefox doesnt acknowledge my normal camera. a few weeks before the update i used a temporary extra camera for a meeting on teams. i normally have meetings with zoom, teams, and a web-based teaching tool. after the update all 3 had switched to the temporary camera, which is not suitable for face-to-face. however zooms and teams offered both cameras and i was able to correct it. however firefox only shows the one (wrong) camera when i access the teaching tool. It does seem to be a browser problem, because the Edge browser does offer both camera. however I do not want to use the Edge or chrome for various privacy related reasons.

I got an automatic update from Opera that I did not ask for, so all of my logins were lost. After recovering them and signing in, when I closed Opera, all of my freaking logins were gone again. There is no way to stop this from happening, because Opera likes to make it difficult to stop auto-updates and to stop passwords/usernames from being wiped out when closing Opera. OK, fine. I'll go back to Firefox, then.

So when trying to login to my Yahoo mail account on Firefox there is a challenge page that sends a verification code to my Android phone. I clicked yes, but there is no place to put the verification from the challenge page. When I go back to the Yahoo mail login page, it goes back to the challenge page again, sending a verification to my Android again. This does not happen in Opera, but there is still the issue of being kicked out of all of my social media, email accounts every freaking time.

I have WORK to do and am not interested in being a coder. I am a writer. So how can I stop this from happening? I would like to go on with my freaking life!

Below is a screen-cap of the challenge screen. Do you see any way to get past it? NO! the only thing that is possible is to get to the goddamn Help screen. I don't want any Help. I want to log into my Yahoo mail. Again, this is not happening in Opera, but Opera keeps kicking me out of my logins.
