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).

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.

Even with the Zoom scheduling extension, I cannot launch scheduled Zoom meetings. Why does Mozilla make this so difficult? With each new version of Firefox, security overwhelms usability, and makes Firefox the least desirable browser.

Hi, I've tried finding the solution online but I can't. My old computer broke a while ago but all my data on Sync was backup up, and I've been accessing it from my Android phone and other laptops just fine. I just got a new laptop and wanted to sign into Sync to get all my data on here. However, even after syncing, nothing is showing up (bookmarks, saved passwords, etc.). It's all still on my phone though, under "Desktop Bookmarks".

Also my phone is currently disconnected from my Sync account because I changed the password to it and haven't logged back in yet. I'm scared that now if I log back in, I will lose everything because it will Sync and take the new data from this computer, which is nothing.

Thank you for your help!

Unable to Sync Notes by Firefox

I recently did a clean install of Window's on my computer. I have a Firefox account and am signed into sync, but I don't know how to get my add-ons and settings back. When I go to "Manage Your Extensions" I see all of them there, but I don't know how to make it so that their icons are viewable in my Toolbar where I can click and use them. What few add-ons I am able to get to show up in the Toolbar I got by either going directly to the add-ons website and installing from there, or by uninstalling them via the add-ons Manager page and then reinstalling. Which in my opinion defeats the whole point of having a Firefox account and sync activated.

Of critical importance is my need to get back the information that I had stored in Notes by Firefox. I was finally able to get the add-on to show up in the Toolbar buy following the above mentioned steps, however I am unable to sign in to Sync. Below I have listed each of the step I take along with attaching screenshots. 1) Click on Sign in to Sync - This opens a new Firefox browser window that prompts me to enter my email to continue to Notes. 2) I enter my email and click the blue Continue button. 3) I enter my password and click the blue Sign in button. 4) I enter my Two Factor Authentication. 5) The browser window that opened when I clicked Sign in to Sync closes and I'm back where I was when I started the Sync process, but now instead of showing Sign in to Sync Notes shows Reconnect to Sync with a warning triangle on the left side. 6) I Click to Reconnect to Sync and got through steps 2 - 5 but Notes still shows the warning triangle with the Reconnect to Sync message.

At no point in this process do I get any error message or invalid credentials prompt.

Please help!

Hello there,

I've recently switched from Firefox to Firefox Developer. I've noticed that while in FF, I am able to change the default fonts (such as San-Serif font to Inter, and Monospace font to Monaco), but in FF Developer, I am unable to change the fonts to anything but the defaults. Can someone help me fix this issue, or is this issue a feature of FF Developer edition?

Thanks a lot, dodeca12

After hooking up four devices to sync through Firefox, I ended up with a mess and a lot of irritation which I have not recovered from. That was six months ago. What I failed to understand is that there is no control of the direction of sync. I presumed that all would sync from my primary account computer. Wrong and truly a disaster because I had spent hours organizing thousands of bookmarks. An old computer with an old bookmarks setup (very disorganized) added its confused mess back into my attempt on the new computer to finally get organized. I still have not sorted through most of the mess.

So how in the hell does Sync actually and exactly work? Is there any directional flow? Or does it just mash the shared stuff together. How can I delete any bookmark file Sync has at Firefox server with exact knowledge of what I am doing? Why is this stuff so obscure? I exactly want to know how to ensure that Sync has no cache of obsolete material and exactly, if possible, to direct the flow....should I use only share a tab? one at a time?

Thanks, Michael Mandeville, Arizona mwman@q.com
