I-Firefox Isithangami Sokwesekwa

I'm asking this question on a different browser because Firefox cant load any websites.

Basically whenever i open a new tab, it opens to a crashed tab. Gah. It cant even load google, or any website for that matter, not even the homepage for Firefox, its just a blank page with nothing on it, whenever i type something into the address bar and press enter it just disappears and does nothing. Browser settings work, but stuff like passwords dont, and i have most of my important passwords on firefox, so i cant log into runescape and stuff.

Can you help?

Firefox does not appear to be using my Mac's default DNS resolver when DNS over HTTPS is disabled. Here is my setup:

- I'm using Firefox 124.0.2 on macOS Sonoma 14.4.1. - DNS over HTTPS is set to Off in Firefox. - My Mac is configured to use a DNS server that blocks some domains, such as facebook.com. I have confirmed that this is working correctly by using the dig tool on the commandline: "dig facebook.com" receives a "status: REFUSED" response with an empty A record. - When I navigate to facebook.com or other domains that should be blocked in Firefox, they are resolved. My expectation is that they should fail to load and a DNS error should be displayed.

What I've tried:

- Confirmed via GUI and about:config that DNS over HTTPS is completely disabled in Firefox. - Cleared Firefox DNS cache via about:networking. - Confirmed every way I know how that macOS is configured to use my custom DNS resolver and that the resolver is refusing queries for the specific domains I expect to be blocked.

I'd be grateful for any suggestions anyone can provide.

I work for the Center for Internet Security (CIS) and my team develops the CIS Benchmarks for securely configuring a wide variety of technologies. Specifically, we make a Firefox Benchmark with recommendation on how to more securely configure Firefox. We would like to get some "Firefox People" involved in helping us update this Benchmark. Some power users and/or some Mozilla folks would be wonderful.

All contributors are listed in the resulting document and the resulting pdfs are freely available on our public website ([CIS Website] https://www.cisecurity.org/cis-benchmarks).

If you are interested please reply and let me know how to contact you.

I had to delete Firefox on my iPhone because links in emails wouldn't open anymore. Yes, it was set for default.

When I re-installed it, the tabs don't close. I hit the X to make a webpage go away and open a new tab. Hit that X when I'm through. Then close an empty Firefox on my phone.

When I reopen Firefox, I get all these little miniature webpages of the tabs I closed. I don't want them. I closed them because I was through. You guys are wasting my time making me close them again and again ...

Please tell me how to set Firefox on my iPhone so that when I open it I get my homepage with shortcuts I have chosen and nothing else.

Thank you, Roxanne

I am attempting to copy values from one google sheet to another and am unable to do so effectively as whenever I press crtl +shift + c I open the the developer tools. All my efforts on looking for a solution have lead me to unsupported extensions so I'm stuck wondering what to do.

Revision: 115.9.1esr (64-Bit) for openSUSE Leap (15.5)

Some months ago, I unfortunately typed a password in the username field of a local page (access to my Internet box, oh Noes).

Since then, it appears each time I remove the access data in the Firefox settings. When entering data again for a login without password enquiry, the password becomes invisible again, and vice-versa.

It is impossible to show the phenomenon using a screenshot, as the password immediately disappears.

I need to install a browser on a Windows 7 laptop that I'm trying to get operational so the files / data can be migrated to another platform. I would like to use Firefox if possible.

I'm thinking I would need a prior version. If so, what version should I choose and where do I get it from?

The current / legacy browser is Brave but that has been disabled by installing Bitdefender as part of the ongoing cleanup process. --Thanks

I'm having a pretty frustrating developer experience using Firefox to help develop an app that uses Server Sent Events. Now, I'm not sure if I'm the one at fault or if it's something to do with Firefox itself (most likely I'm missing a config option somewhere).

Anways, the issue I'm having is that I cannot seem to be able to see Server Sent Events in the network tab of dev tools. This is specifically what I'm looking for: https://firefox-source-docs.mozilla.org/devtools-user/network_monitor/inspecting_server-sent_events/index.html

I'm testing this functionality by going to https://sse.dev/testpage.html, opening my network tab. I can see the connection to the SSE endpoint however, all I see is "No headers for this request" or "No response data for this request". I know it's getting the data through the event source because I can do stuff with the data. I've also tested this in Edge and everything appears in their network tab as expected which, makes me feel like this is more of a browser-specific issue. Again, I feel like it's me missing a config somewhere or having a privacy setting set which is somehow messing with the event stream.

Any help is appreciated... I guess I got to use Edge for the time being 🤮

TL;DR: Make sure you're on the latest... turn Sync off on the computer that isn't showing the remote tabs, then turn Sync back on.

Details:

Three computers (Windows), a phone, and a tablet. Firefox 124.0.1.

Sync is enabled and generally seems to be working fine. But I just noticed, on one computer, that when I went to Firefox View, and clicked on "Tabs from Other Devices", that it was showing nothing, other than the, "Log into your Firefox Profile", which I was already logged in... so that was messed up.

Did a number of things, like checking the other computer, manually syncing from the other computer, coming back to this one, and telling it to manually sync. It also seemed to be stuck in syncing (a grayed button that said "Syncing...")

I looked, and there was an update available to 124.0.2, so I used this opportunity to upgrade.

When I came back in, I still didn't have the remote tabs showing up, so I turned off "Sync" entirely, but didn't log out of my Firefox account, and then turned it back on.

Now I'm seeing the remote tabs.

That's how I fixed it. I hope it helps. I see others having Sync problems, and getting terrible suggestions that are not helpful. In this case it's the simple thing that fixed it for me. Turn it off and turn it on again. If that doesn't work, unplug the computer from the wall and plug it into another outlet.  ;-) ( That's a joke for those of you with a sense of humor. )

I have Firefox on 3 devices, I deleted several passwords from 1 device expecting this change to sync to the other 2 devices. Instead for several days the 2 devices showed the original number of passwords whilst the device I made the changes on showed the new amount. Now that device appears to have resynced the passwords I deleted. Am I supposed to delete them on each device?

I have the latest version of FF on all devices.

I am not sure when exactly problem started but for few months I have problem with automatic update of firefox. It properly detects update and downloads it but when I click to restart browser and apply update (this should close browser and display update install bar) nothing happens - browser simply closes. When I launch it again and go into "about firefox" again I see spinning circle next to "installing update". Of course this update never installs. When I close it for 2nd time and go into "about firefox" it goes back to "update ready to install, click to restart" - and again, when I click it browser simply closes without restarting and installing update. I tried removing my profile, using safe mode, disabling antivirus. Issue seems to be related to firefox itself. I also tried removing mozilla maintenance service but it did not help. Does anyone have any idea what could be causing this? For now only way for me to update firefox is manually download full installer from website and then it installs latest version without any problems - until next month comes and I have to update it again.

Why has my firefox browser failed to connect with my banking website?

Whenever I attempt to watch something on any streaming service, I get an error message from the streaming service and a note from Firefox saying "The WidevineCdm plugin has crashed." I have tried to solve this problem a number of ways, but have unable to find a solution.

My best guess is the problem is due to the most recent WidevineCdm update, as in the plugins settings the most recent update for the plugin was on 10/21/23, which is shortly before I first noticed the problem. I did test out various streaming platforms on other computer browsers (Chrome and Microsoft Edge) — they gave the same website errors as I got on Firefox, but those browsers did not indicate the cause or suggest which plugin failed. I additionally tested out desktop apps for some of the streaming platforms; they work fine without any issues, but unfortunately the main streaming platform I use doesn't have a desktop app and only works in browser.

My computer is a Lenovo Yoga 9i, it's running Windows 11, and everything is up-to-date.

The methods I have tried to fix this issue with, to no avail: - submitted crash reports - toggling the "play DRM restricted content" options in Firefox, and toggling whether or not the WidevineCdm was activated, closing the browser between each toggle of options - clearing Firefox's cache - running Firefox in troubleshooting mode to make sure it wasn't a different extension interfering with it - tried running Firefox in compatibility mode - tried to find support from the people who made WidevineCdm, but apparently they don't do end-user support - deleting the WidevineCdm manually from the program files for Firefox and Chrome (since Firefox says the plugin is from Google), and then reinstalling it via the chrome components page. This briefly lead to the message on the plugin page that WidevinceCdm would "begin installing shortly." It seemed frozen like that for a good while, but then I tried clicking the "check for updates" and that message disappeared, and it went back to crashing when I tried using a streaming service. - uninstalling both Chrome and Firefox, restarting the computer, then reinstalling both browsers

As far as I can tell, the plugin comes automatically installed in the browser, and there isn't an alternate plugin for decrypting DRM-restricted content. If there's a way to set the WidevineCdm to a previous version before the update that's crashing it, I haven't found it, but I am no expert in computers or coding, and my guess about it being caused by the recent update could be wrong too.

I'm at my wit's end here, any help fixing this problem is greatly appreciated.

Over the past day or two, I've seen firefox incorrectly render fonts on a couple of websites. So far, I've only noticed two websites effected: quotientapp.com and xero.com (not the actual landing page, but rather the login page and other pages available after login https://login.xero.com/identity/user/login). This problem may extend deeper but these are the only places I've found them.

At first I thought my eyes were playing tricks on me but nope, something definitely not right. No new addons have been installed on my system. I've also deleted all local storage / cookies (via the Inspector) for these sites thinking it must be some caching issue - but no, it's still doing it.

Inspecting the font-family shows the issue (this is from the page https://go.quotientapp.com/sign-in) - have attached the images below of what I see.

I do use uBlock, but it is disengaged on Quotient and Xero (these are work related sites, they show no ads). Other add-ons I have installed include Bitwarden, Dark Reader, Firefox Multi-Account Containers and Reddit enhancement suite. I've ensured all add-ons are up to date as of this posting.

FWIW I do allow all the extensions above (with the exception of Firefox Containers which I don't allow) in private mode.

Any insights on how to get to the bottom of this?

Clicking on a link in a Thunderbird email does not cause Firefox (the default browser) to open that link. If either Chrome or Brave is set as the default browser, they will correctly open the link. Obviously, the problem is with Firefox, not with Thunderbird. I raised this issue several years ago and have never received a response. I have drastically reduced my use of Firefox accordingly. I am primarily a Linux user (Ubuntu 20.04 LTS, gnome shell 3.36).

This is a rebuilt PC after a hard drive died, Windows 10 Pro N version 22H2. and YE

I am trying to access video content on cbc.ca or Amazon.ca and receive an error message that "no compatible source was found for this media" - Amazon or on cbc.ca "Oops...None of the given sources can be played".

Prior to updating Firefox to version 123.0.1, both played video on these sites without an issue.

I have uninstalled and reinstalled FF and the issue persists. I can play the video from these sites with Chrome or Edge without a problem.

I have installed Java and have tried all of the help tips without success:

I have followed and installed recommendations from : https://support.mozilla.org/en-US/kb/fix-video-audio-problems-firefox-windows however the latest Media Feature Pack for windows is from 2019 and is no longer applicable to the 22H2 version. https://www.microsoft.com/en-us/software-download/mediafeaturepack. Windows store does not offer the pack.

The changes suggested by https://support.mozilla.org/en-US/kb/block-autoplay have been applied and no change

I am not running malware bytes or a VPN.

I have cleared my cache, and browsing history, rebooted = no change.

I have no add-ons, extensions or themes installed.

I prefer to use FF, but require that I can view videos from many sites.
