Where can I find help for the Firefox Developer's menu which appears after pressing F12 ?

I have tried to download via it a YouTube music and save it as follows but it doesn't replay: What's wrong with this `curl` command ?

Upgraded to a new Firefox version. Lost the ability to separate the Homepage from New Window behaviour. Is there no way to specify these two things separately? It seemed to be working fine when I first upgraded, but in the options it shows everything as "Blank Page", so if I want to change my homepage URLs, I have to set it to that and if I do that, it undoes the separation of the homepage and new windows and I have to go set it again in about:config...? One of my most used features was this separation of the Homepage with New Windows, gave me a lot of control.

Upgraded from 60.9ESR to 78.8ESR Tons of empty white space being wasted in my address bar drop down, and the preferences+addons pages now only occupy half the screen so I have to scroll more to see all my options, click to fully read text boxes and open sub-menus?!

How can I make these things more compact? The Customize options don't affect them, though I've changed the "blow-up" address bar behaviour using policies.json.

I am getting the message "Access Denied You don't have permission to access "http://www4.citizensbankonline.com/efs/servlet/efs/loginnew-wait.jsp" on this server. Reference #18.ad674d68.1618522318.738da43 " when I try to log on to my bank. I'm running Windows 8.1 with Windows Defender and have accessed this site for years. When I called the bank's tech support their response was "Why are you still using Firefox? Everybody uses Chrome now." I do not use Chrome, but Edge will access the web page with no problem. This has been occurring on and off for several weeks and I have tried all suggested solutions I've found here so far (clear cache, history, DNS prefetch.... ). I've also noticed numerous other posts with the same error message. Any ideas??

I unstalled my old Firefox version without saving my bookmarks. I then installed the current Firefox version and realized that all my bookmarks are gone. I tried already to restore them, it finds the file, but then I cannot import them. The c:\windows.old thing does not work for me. Any other ideas where to look for my old bookmarks? Thanks, Daniela

I got a message on firefox that it was running slow & if I reset my firefox browser it might help speed it up. It also said that it wouldn't effect my logins & passwords or my saved bookmarks, but after clicking on the reset as instructed, I lost everything! I'm not sure what to do.... I clicked on restore bookmarks, but it said can't access the file... Is there any thing I can do to get them back??

Will restoring the laptop to an earlier date work?

Any help would be so very very much appreciated. Thanks, Sheila

I don't see another place to post this. If someone provides a link to a tracker I'll be happy to repost. I should also probably open these items in different posts. I will do so if required.

I see a few places where Multi-Account Containers can be improved:

1) More icons - ability to use all Google Material Icons, even if the ID is manually entered 2) More colors - with color wheel or entry of #RGB 3) From the Multi-Account Containers Support page, "The sync feature will align Multi-Account Containers on different computers" - This does not appear to be working with v87 on two systems. 4) Also from that page, "Assign a website to a container" does not appear to be documented: Three dot Page Actions in address bar > Alway open this in a container.

Am I missing existing functionality or documentation?

Thanks!

Firefox 8.6.0 upgrade disables Firefox browser I utilized "System Restore" through the process of elimination I determined that it is the 8.6.0 upgrade that is causing the problem. So, turned off the automatic upgrade option and installed any Windows 8.1 upgrades and my Firefox is working great. Now I have a "nag" screen that is constantly trying to upgrade Firefox browser might there be some way to disable this upgrade notice?

Lately almost every time I use Firefox, RAM usage goes up to 5 GB, CPU usage goes to 100%, and my PC becomes unusable until I kill Firefox processes and wait 5 - 10 minutes for virtual RAM to be cleared out of disk and disk usage to return to normal. This is much worse since the last update, basically making Firefox unusable. Is anyone working on fixes so Firefox doesn't need 5 GB of RAM to open one simple web article?

I went to a government site and filled out a form letter and each time when I hit the VERIFY key the reCAPTCHA function tells me I have a bad connection and to recheck it. When I hit the refresh (circle arrow) link, it works. It happened on another non-gov't site and did the same thing. I did a Firefox refresh and that didn't help. It seems that version 87 has some bugs in it methinks. Any ideas? thanks

You can work around the issue by stopping the video currently playing in the YouTube tab before navigating away from its page.

I suspected the usual problem of hardware acceleration / video drivers and Firefox not playing nice, but thanks to the PortableApps.com Firefox builds and their version archive, I was able to confirm that it only happens on Release 86 and newer.

Since it's reproducible with the PortableApps builds, settings/profile/cookies etc., it seems pretty clear it's an issue with Firefox proper.

I've downgraded my main Firefox installation to 85.0.2 for the time being and am enjoying snappy YouTube without hangs again.

Anybody happen to know if that bug is already known / under triage or should I get comfortable with the idea of having to downgrade to and using Firefox ESR for a while?

I have recently updated my browser to version 87...unfortunately I had to revert to version 85.0.2 because the browser pegs CPU every time there is an advert on Youtube. Doesn't matter whether I let it play in its entirety or skip it after the mandatory 5-second mark. I have tried running FF without addons, did not make a change. I tried opening a single window with a single tab...no result. Can you fix it in some kind of micro patch? I'm running W8.1 on i5 6600K clocked at 4 GHz with 8 Gb RAM in a dual channel.

B4 I updated to Vers. 87 Firefox was able to save a download to my assigned desktop folder, but now it does not. Prior, the downloads would be downloaded to Firefox first then go to the folder. Not any longer because the blue download arrow isn't showing up. Any suggestions on how to correct this? Thanks
