I'm trying to use the Firefox "Logins and Passwords" saving option. With one website, when I open it to the login page, Firefox enters the password in the username field and nothing in the password field. I've checked "Saved Logins..." and verified that the information is entered correctly. Why doesn't it work?

Hi,

The version of Firefox 68.9 on Linux CentOS 8.2 has problem playing videos from https://www.udemy.com Testing on macOS and Windows 10 the Udemy Courses are presented fine. I get dark video.

How do I get rid of the "Download the new Microsoft Edge" banner that keeps popping up in Firefox? I have checked for solutions on the web and have already gone into Windows 10 settings and disabled the "Get notifications from apps" option, and unchecked the "Get tips, tricks and suggestions" box. That doesn’t help at all.

I am using Firefox 77.0.1 with Windows 10 Home, Version 1903. My computer is a Dell Inspiron 1650

Firefox 77.0.1 (64-bit) - Sometimes when clicking on a URL, as the page starts to load Firefox grabs the mouse pointer and freezes it making it impossible to do anything else until the page completely loads. Are there any settings that might cause this to occur or would prevent this from occurring?

Hey y'all,

So last week I opened up Firefox and half the websites wouldn't load. I would click on my bookmarks or type in the URL and nothing would come up. It refused to even attempt to get on the page, nothing would come up. The page would be blank. My extensions weren't working, either, and some websites had logged me out. So the solution I found via Support was to do a Refresh.

I did that and everything worked great again. My bookmarks and tabs were saved, I just had to fiddle with my extensions and theme.

Now, only a week later, Firefox is having the same problem. Websites not loading, extensions not working. I'm using the latest version on Windows 10, so that can't be the issue. Do I just Refresh and hope it doesn't happen a third time? Doing a weekly Refresh would be such a nightmare.

I love Firefox, especially because of the extensions, but that's the only thing I can think of that's causing this issue. I don't have that many and I don't want to get rid of them - they make using the internet bearable.

Thanks~

I have a strobe sensitivity and visual motion sensitivity, so the default Firefox settings aren't safe for me.

(For example, the default settings have flashingcursors, autoscroll, smooth scrolling, autoplay enabled, no ad blocker installed, etc.)

I can't use a new profile unless I can copy over all my existing safety and accessibility fixes. Besides about:preferences, that includes a number of fixes to about:config, userChrome.css, userContent.css, and a number of add-ons.

I am not quite sure what the Autoconfig can do, or how to set it up, but I understand I would need to manually track down and copy all my safety settings, which isn't even possible with the current about:config. And wasn't practical with the old one.

Anyway, trying to follow debugging instructions, which often involve creating new profiles, and then copying everything to these profiles so I can test them relatively safely, has gradually screwed up my Firefox installation. A lot of freezes, the url bar going unresponsive, etc.

Maybe if I can sync to a dummy location and then back I can fix this. I don't know what else I can do.

Since I updated to 77.0.1 firefox has for unknown reason has concluded that there is a system administrator which has disabled updates. It says so in setting (topleft) and in about firefox (instead of update button). I have been able to change all other settings that I know of. I have also refreshed the browser once, disabled all addons once, and deinstalled it to reinstall the latest version once.

Is there a solution for this bug?

I am now getting extremely slow response from weather.com when requesting radar images. It takes over 30 seconds for the page to load. The same page on Safari loads in a few seconds. Also, a Firefox process drives one CPU core to 100% busy for the duration of the load. This something that must have degraded in the last several updates. I'm using Firefox 77.0.1 (64-bit) on macOS. Any one else have this trouble?

The last month many times FF is crashing. I cleaned FF, Intsalled again, checked hardware, etc.......nothing helped

A month to a few weeks ago Firefox started being laggy when switching tabs; also Facebook and Facebook Messenger; on Board Game Arena and also on Discord desktop app (using Electron/chromium) typing was getting laggy. I thought it might be hardware so I tested the memory with memtest86 but that passed. I also tried safe mode on Firefox but that made no difference.

So I reimaged my HD to a known good copy from December 2019 and then also recently to 2018 and updated to latest version of Windows 10. All seemed well but recently again Firefox has gotten laggy. Even typing in here it occassionally hangs.

I've attached a Firefox Profiler link https://share.firefox.dev/2Zlua5o if that helps with me doing moves on https://boardgamearena.com/ website with each move taking several seconds to do.

I have also the profile with more private information if that helps.

Can anyone help me troubleshoot?

When I try to read my mail on Microsoft 360, on Outlook, it opens. When I click on a message, it will show up in the preview pain but when the popup open's the email, nothing shows. If I use another browser (IE) it works fine.

I built a web application using WebRTC technology.

My case is that I browse the web site on my android phone using Chrome version 83, and then I browse the web site on my pc using firefox version 77. And the server-side code is using node.js. It works fine.

When I switch the connection on my mobile from wifi to mobile network or from the mobile network to wifi, both browsers are handling the "onnegotiation" event infinity.

However, if I browse the web site on my pc using the Chrome browser, the problem does not exist.

I am using the perfect negotiation method to establish a connection.

I have tried to rebuild the connection in socket.on("reconnect"), it does not work.

How can I fix the problem?

And my source code can be downloaded from the following URL for reference:

Anyone else notice excessive cpu usage with Firefox 77.0.1? It's been going on for the past week. 17.6-27% cpu usage just sitting here on the support page only after a fresh restart of the computer.

I also just noticed tonight not a single page would load. Switched to trouble shooting which disables the addons and pages loaded. Closed the browser and opened it again to be in normal mode and started disabling addons. The one I disabled to get pages to load again was Adblock Plus. Go figure of all the addons this is the one that is going to kill the browser from loading anything. I've already sent a report for this on the addon itself not sure what else to do there other then enjoy a bunch of adds for a while.

The one that concerns me more is Firefox just sucking away at the power for no reason at all. I can fill the top bar with tabs normally and not be using this much cpu. I would say it has developed a memory leak of sorts or something considering it's using 0 disk and network activity yet currently is using 18.4% cpu and 635MB memory for this single page being open.

5 or 6 pages that I used to look at more than once a day no longer open, what is stopping them? It says firefox can't make a connection, yet I know the page is there, this is very frustrating.

Hello everyone!

Firstly, greetings to the community, I hope you people are staying safe. Please refer to my previous questions number one and number two. Do note that my second question has NOT received A SINGLE REPLY from anybody. I have now updated to version 72 and then subsequently to version 76.0.1 (which the latest one at the time of writing this question. I am still suffering from the same problem of stuttering 1080p 60fps YouTube videos due to frame drops, especially using the VP9 codec, although other codecs also drop a few frames. Do note that the audio works just fine in real-time without any lag, and this problem exists ONLY for 1080p @ 60 fps, not for any other resolution or frame rate. I have referred to the following links to try and solve my problem:-

1. https://www.reddit.com/r/firefox/comments/8qhbhg/h264_1080p_60fps_stutter_youtube_vimeo_etc/
2. https://support.mozilla.org/en-US/questions/1277519
3. https://www.mozilla.org/en-US/firefox/72.0.2/releasenotes/
4. https://bugzilla.mozilla.org/show_bug.cgi?id=1608485

The Firefox version 72.0.2 release notes categorically state that the issue has been resolved and even points to the bugzilla page for the same. But it still exists even in version 76.0.1, which is surprising. I have tried every possible combination I can think of, from setting media.media-capabilities.enabled = false in about:config to disabling specific codecs and hardware acceleration, none of which solved the issue permanently to my satisfaction. A few settings, at times, improved the issue slightly but there was no permanent solution, even though this has been alluded to in a previous release note. Do note that my graphics drivers are updated and this issue is Firefox-specific, i.e other browsers work just fine. Even the older versions of Firefox work fine, as stated earlier. I would like to state that I prefer using the VP9 codec because other codecs take a toll on my relatively low-bandwidth network connection and this leads to longer buffering times (VP9 does not have this problem). I humbly request the community members and volunteers to help me in this regard, and if need be, point me to the proper channel for lodging a bug report directly to Mozilla.

Thanks and regards,
Preetodeep Dev.

P.S:- If this issue is not resolved, then I will have no choice but to go back to Firefox version 62.0.2, which works just fine with all the default settings.

Just updated to the latest version but when I load up Firefox and select a website, it isn't loading the page.

I've tried other browsers and these work.

I've cleared my cache and history and reset my connection and still the same, won't load a page.

Whenever I search for a new subject(not pre-searched) no results are shown and I get the message "Hmm. We’re having trouble finding that site". This happens only when I use Duckduckgo to search. I have updated firefox to the latest version, used safe mode, and cleared all my browsing history but none of them have seemed to work. I have been facing this problem since 2 days now and initially I used to get the error message "PR_END_OF_FILE_ERROR". Thank you.

Just updated to version 78.0.1 (64-bit) on Windows 10 and now my tabs will NOT load/hanging, even after several restarts. PLEASE FIX THIS ASAP, I have work to do!!!
