Firefox Support Forum

As described in this thread (https://support.mozilla.org/en-US/questions/1431159#answer-1618832), I had a problem accessing one particular domain after doing everything I could find to fix it. Setting DNS to Increased Protection fixed it. It's partly just curiosity but also concern that I'm asking if there is an issue that should be addressed.

The basic scenario: could not access one particular domain only in FF on one computer. No problems with FF on other devices and no problem with other browsers on the computer in question. Configuring DNS settings to Increased Protection is the only thing that allowed me to access that site (which happens to be the org I work for). So the setting is only necessary on this device and only for that domain.

What's the explanation or solution for ensuring I don't have other DNS issues, or something else, that will be a problem later?

Hi,

After updating Firefox to 116.0.1 my tabs keep randomly crashing. I get some crash reports *occasionally* - meaning not all crashes produce a crash report - but I'm not sure what to do with them, they seem inconclusive. The last report (not for the last crash, though, which didn't produce any report) is bp-3334b934-58b5-4226-887a-235300231117

I'm not very computer savvy but I followed a website a few months ago to edit Firefox so it'd default to dark mode. I think I went in and edited source code? I can't find the instructions anymore but I'd like to revert back to the original setting. How do I do that? I tried to refresh Firefox but it's still coming back with some websites in dark mode and some not. Please advise!

Help, I do not know how I got stuck with this but every time I go to twitter I get this tab pop up window and cannot get rid of it. I am not versed enough to get rid of it. Please, please help get rid of it. https://twitter-com.translate.goog/home?_x_tr_sl=en&_x_tr_tl=en&_x_tr_hl=en-US

There is one domain that I get a "server not found" error for even after doing many things to fix it including everything here, https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can#firefox:win10:fx119, checking blocked URLs in the registry, running malware checks, safe mode, reinstalling FF after removing all FF folders from my system.

Before I did a completely clean reinstall, disabling the Open H264 codec (see attached screenshot) would allow me to access the site. But thinking it was needed, I did the clean reinstall. Now disabling it does not allow access to the site.

So far, I have not found any other websites with this problem. It's a .edu domain which happens to be the one I work for! What else can I do?

Hi, so here's the issue I have: Lets say you have 20 tabs open where the "tab scroller" becomes active and tab#17 has a video, if you enter & exit fullscreen on that tab then tabs #18-20 will slide to the right and go out of sight. This is quite annoying as I'd prefer all tabs on the right to be visible until I manually scroll to the left.

I tried googling for about:config or userChrome.css solutions but couldn't find anything, does anyone have any ideas on how to change this? Thanks.

I tried to watch a youtube livestream today and it failed to play. Non-live videos on youtube are playing, even the same videos watched as VODs after the stream ends, but the livestreams are providing "Your browser can't play this video" errors.

Simultaneously, I'm noticing that some videos on Reddit (such as embedded tiktok videos) are stuck with a circling ring and won't play. At least some of the same videos will play on Tiktok (when I can find them).

ALSO, when I try to watch videos on my Nebula subscription, I'm getting a "This video could not be loaded: 4" error code. ANY video on Nebula.

What the heck gives?!

Title. I've followed every guide I've found but the issue still persists. I've created a new profile, reinstalled ff after deleting the whole file from my pc, deleted all cookies for a dozen times, disabled all extensions, started ff in that problem mode or whatever it's called and I still can't login to certain websites.

I type my login credentials, press "continue" and nothing happens.

I hate how much information Google gathers from their users but I used Chrome for five or more years and I never had this issue with their browser. Not once. Even now I constantly have to go back using Chrome because with it I have no issues logging in to the sites while on FF I just can't.

What is going on?

Outlook recently made Edge or Chrome the default browser, with no possibility (as far as I can see) of choosing Firefox. In Outlook FILE/OPTIONS/ADVANCED, it seem impossible to choose Firefox.

How can I make Firefox the default browser. This situation occurred after recent update (October 2023).

Any help would be appreciated. -- JGS

For context, I accidentally made my root D: folder into the downloads folder and during this time I was still able to download using firefox. But when I finally changed the folder to my default one, firefox stopped being able to download anything larger than 1gb files. I can still download small images but anything larger than that I can't download. Else, it would only just show "Failed" in the downloads bar.

I've tried: 1. Changing the download location

>Also tried reindicating my download location

2. Turned off dangerous downloads 3. Putting an exception to the sites I try download from 4. Clearing the downloads 5. Tried troubleshooting mode 6. Restarting my computer 7. Restarting Firefox

I can't download on firefox but the same files I can download on Chrome.

I am unable to de-select the "Ask to save logins and passwords for websites" setting. The option is checked and I cannot "uncheck" the box. The texted is grey and the check box is a light color denoting it's not able to be toggled.

I searched for a solution and it's not the same problem as others are having where they have the the "never remember history" option enabled. My setting is "remember history."

I am a personal user, and this is my personal computer. I have admin rights on my computer. Running Windows 10 Pro.

Screenshot attached.

Thank you for any help with this.

Firefox remebers my data for previously filled in forms - thats fine. BUtr how can I get it to know my basic data (name, email, phone number etc) for forms / sites I havent previously visited?

Hello!

I often log in to a service ticketing website to help my customers. Before emailing them I must reference the service ticket number somewhere in the email, but this is very difficult to do in Firefox. If I inspect the element this is what I see:

<em unselectable="on" style="width: 2161px;">Service Ticket #55474079</em>

I understand the unselectable attribute is on but even if I try setting it to off or deleting it all together the problem remains. Moreover, I've tried it in several browsers (Chrome, Edge, DuckDuckGo) and it works fine without any extensions or tricks.

In other words: only Firefox keeps me from selecting this very important piece of info.

Any help would be very much appreciated! I looked up help articles but nothing similar to my case. I did find an extension for the browser but I am afraid to try it due to security reasons.

Thank you!

Whenever I try to download a rar file, like a game from itch.io,0 it automatically fails and doesn't download even after retrying multiple times.

Majority of the songs do not play and I'm given with a pop-up, "Spotify can't play this right now. If you have the file on your computer you can import it."

I will play a song from a playlist and is given that pop-up, it will continue skipping to the next song until it plays, but only for 9-10 seconds until the song mutes, to specify, the dot (when hovered on the progress bar) will still move, indicating that "it's playing".

Some clarifications: 1. I use Spotify Desktop app (windows), Spotify App (android), and Spotify Webplayer on Chrome and Firefox. Everything works just as fine on all of these, except for Spotify Webplayer on Firefox. 2. Skipping to a later timestamp does not unmute the song. 2. I have Spotify Premium 3. I have no VPN 4. I am running Firefox with an ad blocker 5. I am running Chrome with an ad blocker (same ad blocker in Fifefox) 6. I am running Firefox to the latest version (Firefox 119.0.1 (20231106151204))

What I've done so far: 1. Cleared caches and data. 2. Updated my Windows to the latest update available - Win10 v.22H2 3. Signed-out of Spotify for all my devices, then logging-in first on Spotify Desktop (this automatically redirects to Firefox webplayer) 4. Ran Firefox on "Troubleshoot Mode" 5. Un-checked and re-checked "Play DRM content" setting. 6. Disabled and re-enabled the plug-in "Widevine Content Decryption Module by Google Inc". (this plug-in is last udpated on November 17, 4.10.2710.0

I'm including this link from Spotify's Community page.. where two other users, who commented it is only with Firefox (webplayer), are experiencing the same problem as I am. https://community.spotify.com/t5/Desktop-Windows/Spotify-can-t-play-this-right-now-If-you-have-the-file-on-your/m-p/5679914#M123192

Lately, far too many websites I try to open, simply won't! Sometimes it's via links from my home page, sometimes it's links within various websites, like a newspaper, or social media, just whatever, no rhyme nor reason, nor consistency. Even when I manually input the url, nothing happens, the browser just sits there, nothing happens. I've restarted, I've refreshed websites, clicked on "open in new tab/window", nothing gets it to work.
