Firefox Community Forum

I am trying to edit /etc/hosts file. CLI utils respect the values that provided there, Chrome also.

But the Firefox continues to ignore. I have disabled "Enable DNS over HTTPS using:" and turned it off.

But it doesn't help. What else could be done?

On my old iMac, Firefox remembered sites I had visited and filled them in, like if I typed A it would autofill Amazon. This is not happening on my new 2023 iMac and I can't figure out how to turn this on. Also, I could see my site visit history on my old iMac, but this field is blank, with no history of sites visited shown, on my new machine. Help is appreciated. Please keep in mind that I am technically retarded and need step by step guidence. Thank you in advance for your help

Hello,

I have tried to download the newest VDH Companion App (via the link on the github.com webpage) Seven (yes, 7) times and every time the download Fails or I get "Zero bytes". I tried to contact "Support" but there is only a Support Forum and nobody else has posted this as an issue that I was able to find when I searched. So no support is offered. The website suggests that I create an account to be able to post a new issue. However, Every time I have tried to set up a github.com account, I am Unable to do so. The page to set up an account either doesn't load OR if it loads, I can not add any information to it. I am a VDH Registered User and until this morning, the current VDH app I am using, version 8.2.1.1 was working just fine. But now when I try to use it, it says that my VDH Companion App needs to be updated. But I can not even download it to update it. I am running the current version of FF, 123.0.1 on an iMac with Sonoma OS 14.4. We used to be able to email Mig but not anymore. The github.com support page is unwieldy at best and I see that numerous requests for help or support have not been answered or even acknowledged. I am a paid Registered user with a license, but that doesn't seem to matter. I, like many others from what I read online, count on using this app almost every day and I would think that the mechanism for updates should be working correctly. The update files I tried to download came across at crazy low speeds, like 20.1 to 40.5 Kbps! I spent over an hour with Tech Support for HughesNet and much to my chagrin, No Other Websites had any issues with download speed. It was only happening on the github.com website and this one file update. Sorry if TMI but I am just trying to thorough.

Hello team,

I tried searching for a solution for the problem I'm about to describe but unfortunately I wasn't able to move forward.

I am running Firefox 141.0 version on my Macbook M4 Pro. The refresh rate of the display is set to 120Hz, but I the scrolling and interaction in the browser feels like it's on standard 60Hz refresh rate. When I compare it to Safari/Chrome it's not as fluent as it should be.

Am I missing an existing option that could be changed or is it something available at the moment?

Thank you, Arsen

Hello,

First time posting here, so I'm hoping that someone can help me out.

I'm encountering a very odd issue on my Macbook Pro running MacOS Sonoma 14.4. I am unable to access two sites – allrecipes.com, and seriouseats.com on my home WiFi network on the Macbook.

These sites work on other browsers (tested on Safari and Chrome), and they also work on my iPhone.

Oddly, when I went to work and tried to access these sites via WiFi using Firefox, I was able to.

I am unsure what the problem is – the ability to access these sites on Safari, Chrome, and my iPhone at home suggests that it's not a network issue. I haven't encountered this issue with any other sites.

I am attaching three screenshots 1) The error message that I'm seeing for allrecipes when I attempt to access the site 2) The security tab which shows that the connection is unencrypted for allrecipes (home network) 3) The security tab showing that the connection is encrypted for alrecipes (work network)

Thanks

I received this download from Firefox today, July 22, 2025: xRqj7qhl.html - Size: zero bytes - Kind: HTML text . I've never experienced this before. Is it legitimate? Thanks

Hiya,

I use a theme which some years ago (after a change in the way Firefox handles dark-mode preferences) changed all UI and websites to use dark-mode. I was able to keep using the theme, and mostly override this behavior by setting:

`layout.css.prefers-color-scheme.content-override = 1`

However, this didn't take for some components, such as the sidebar and bookmark editor window, which still continue to use dark-mode.

Is there any way to completely disable dark-mode everywhere, and still use my preferred theme?

Cheers, Afraz

Chrome is fine.

Hi friends. We have had some recent power outages when everything was back up running my youtube screen only shows the video but everything else is white. I will try to attach a screenshot.

I am running an iMac with system Sonoma 14.4.1 installed.

I have used Firefox for over 10 years with no problems.

York Maine [removed phone# from public]

I want to re-order the add-ons / extensions in the toolbar shared with the search bar. Customize toolbar only has functions/icons related to the operation of Firefox. I want to customize the extensions toolbar, but how?

In the add-ons page, I can remove, disable, or enable extensions, but I cannot change the order of them.

As an example, there is an add-on for my Firefox account that is leftmost in the bar of extension icons. I would like to move it all the way to the right. Again, how would I do that?

Thanks for your help.

Is there a security setting that allows me to show all my passwords rather than having to toggle them on each time?

I am a recluse. There's never anyone looking over my shoulder. I just don't want to have to mess with it anymore.

If there isn't, could some kind developer please make an add-on?

I am using two computers: an iMac (late 2009) running 10.13.6 (High Sierra) and a Macbook Pro (13-inch, 2012) running 10.15.7 (Catalina).

Thank you!

Hello

Hello all,

I'm running Version 108.0.1 on a mid 2015 Macbook Pro MacOS 12.6.2 Today I went to do a translation using the "to google translate" add-on and noticed it was missing from its place in the context menu. I go to "get more add-ons and re-installed it.

So why was it uninstalled without my consent? What can I do to stop this happening again?

TIA, Gene

I frequently open new tabs by right-clicking the current tab and choosing "New Tab" from the context menu. Naturally, I want to start typing a URL or search term.

But the focus/cursor/caret is nowhere and typing does nothing. I have to click on the address bar, and then I can type.

I'm not using New Tab Override and I have Firefox's new tab set to a blank page.

I tried disabling all my add-ons, but I still had the problem.

I tried setting new tab to the Firefox home page and for a short while I got a cursor in the address bar. But the problem returned after a few hours

Any clues on what might be wrong? Firefox version 120.0.1 (64-bit) on MacOS Ventura 13.5.1. Thanks!

(A similar problem is described here: https://support.mozilla.org/en-US/questions/1420220 -- but in my case this is not a container tab.)

Hello friends,

As the title of the subject entails, I am trying to disable Firefox's new translation tool, becasue I'm using a 3rd party extension.

I tried to follow the solution on the following support thread ( [https://support.mozilla.org/en-US/que.../1434741#question-reply] ), but it didn't work for me, and I'm still seeing the new translate button.

Is there another way to fix this?

I'm using Firefox 129.0.1 (64bit) for MacOS.

macOS 15.6 Firefox 141.0.3 - my preferred browser

I've seen a number of posts regarding this problem since the Firefox 141 update. I've tried a number of suggestions, although my problem seems slightly different.

I can apparently login to reddit OK but when I try to access a subreddit thread, a warning comes up - see image.

I have cleared Firefox site data, cookies, cached files, etc - problem remains.

I have restarted Firefox in Troubleshooting mode - problem remains, so not an extension.

However, https://old.reddit.com has no problems with Firefox, lets me access threads, etc and comment.

No problems accessing reddit with Safari or DuckDuckGo browser.

Firefox 126.0.1 displays a very long name of a container completely in the URL bar.

Firefox 127.0 truncates container names

AWS long account and role names make keeping the long name very convenient (works with the 'AWS SSO Containers' Add-On

Hey,

I've been having an odd issue with Firefox where tabs where I attempt to access youtube.com will immediately crash. This issue first arose when I attempted to log in to Youtube, and had never occurred before. When I did that login, the tab crashed, and I have been unable to access the website since (100% crash rate).

Basic details: The website does not visually load at all. However, the URL bar icons for the website do briefly appear prior to tab crash. (Autoplay button, etc). The crash is never reported in about:crashes.

I've tried the following tests, unsuccessfully: - Logging out of all Google accounts separately - Disabling all extensions - Transferring all of my data to a new computer - Reinstalling Firefox - Rebooting Firefox in troubleshooting mode

This problem does not occur on my Windows machine but occurred on my previous intel-based Mac and now on my current Apple Silicon Mac.

The only success I have had is in creating an entirely new Firefox profile. However, I would prefer to fix the issue, as I assume that porting all my settings to the new profile would... also probably bring the bug along.

Thanks for reading & any advice is appreciated.

Since the Tahoe upgrade I can't login to my google account because the 'Passkey' prompt that the system is supposed to automatically trigger, never eventuates as it used to in Sequoia. I am signed into my account on the same desktop using Safari but my preferred browser is Firefox, so this is quite frustrating.
