Firefox Community Forum

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

My bank has recently switched the position of 'online' and 'bank name' in its login URL. How can I delete all history for the old URLs (e.g. Bankname*) without deleting history for all non-bank-related URLs?

I'm encountering some difficulties with my current account, which is locked out. I would like to request assistance from the support team to help me delete my account and remove my personal information from the platform. However, I'm having trouble finding the contact information for the support team. I couldn't locate their email address or phone number, and I'm hesitant to post my personal email address and information on a public forum.

I'm feeling quite frustrated, as I've never encountered such challenges with an app before. It appears that I'm unable to reach the Firefox support team at the moment. Can someone please provide guidance on how I can securely and privately request their assistance in deleting my account and personal information?

I had to create a new account just to post this question because my original account got locked out. This happened because I recently acquired a new phone and didn't transfer the two-step authentication information to my new device.

When signing in to websites, firefox offers e-mail address options that havebeen used before on that site. But right now it keeps offering two, one of which is incorrect, and I thought there was a way to fix that, but right now I cannot remember it.

This is explicitly for sites where I have told firefox *not* to save the password, and it is offering up potential email/login. entries *only*.

I do not want to tell firefox to not offer to autofill anything ever, because that saves time when the entries are correct. but here they are *not* correct and I need to clear them for this one specific website.

How do I do that?

I have been using Firefox for many years and I have never had problems, until now, out of nowhere Firefox closes and the little window opens that the report is being sent to Firefox, but I can no longer restart or open Firefox, until I reset the computer, This can happen one, two, three and even four times a day, making it very uncomfortable to reset the computer.

I have already tried many ways to solve the problem, from completely uninstalling Firefox and reinstalling it, I use very few extensions, I already disabled WebGL and also disabled hardware acceleration, nothing has worked, when Firefox closes, I cannot open Firefox Developer either and That browser was not even open at the time of the failure with Firefox.

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.)

Up until this last update, in Gmail inbox, each message could be moused over top and action icons would show up. This no longer happens and I don't know why. It was very convenient not to have to open the message to take action on it and then return to the inbox. Now if I click the checkbox on the left side of the message those icons appear, but I never had to do this before??? I have not made any changes to the settings on my 1 year old Macbook Pro or Firefox configuration...

Firefox stopped working with my VPN on when I updated my OS to Sonoma, yesterday. I use PIA for my VPN.

I have done the following, so far, restarting my system several times between trying these things:

Checked that internet connection and modem are fine. All pages load in Safari, with VPN running, but I prefer Firefox.

Checked the Network settings for my Mac. Ensured that No Proxy was selected.

Cleared my Firefox cookies, cache and history.

Tried running in troubleshooting mode, turning off all extensions.

Tried turning off Advanced Tracking Protection, which I usually run on Custom.

Refreshed Firefox.

Finally, I turned off my VPN and, viola, all sites work. Turned it back on, and can’t navigate, again. For instance, I tried to open YouTube, and got a blank screen. Turned off VPN, and got to main YouTube page. Turned the VPN on and tried to log in…nope. Turned it off and logged in. Turned it back on and tried to open a video….nope. Turned it off and opened the video…etc., etc..

I very much wish to continue using both Firefox and my VPN. Can you suggest a course of action? Thank you for any advice you can give!!

I can no longer access my online banking at td.com - the server returns the following message: "Bad Request - Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

The online banking works normally with Safari. Please help me fix this quickly.

Thank you.

I am having an issue where youtube videos played at higher quality stutter when put to fullscreen. Up till about 720p60 works fine, at 1080p60 and above the framerate becomes unstable.

Things I have tried: - I have tried going into media.media-capabilities.enabled and changing it from false to true - I have set network.buffer.cache.size to 262144 - I have disabled all my plugins - I have tried changing my user agent to windows/chrome

My current setup: Firefox 122.0, Macbook pro Sonoma 14.1, Apple M1 Pro chip

Curiously, if I make a new firefox profile and play a video there, there is no stutter. Does anyone have ideas on how I can fix my current profile?

When I go to website nypost.com, and select a random article that has a video display at the top of that page, a pop up of a smaller video window appears in the lower right corner of the screen.

For example,

Go to nypost.com Select an article with a video such as https://nypost.com/2024/01/30/metro/phony-uber-driver-charged-with-ripping-off-nyc-bar-patrons-in-cellphone-scheme/

There is a pop window of a smaller video screen that shows in the lower right corner

Autoplay is disabled

Is there a specific setting to stop this functionality of the pop up video window to appear? Is the block pop up window functionality in the same category of this description supplied above?

Thank you.

I restarted my computer today and downloaded a new version of Firefox. When I started it up again everything was gone... all Tabs, history, and bookmarks. This is a sad loss as I have been organizing my life with Firefox for over 10 years. Is there any going back and getting my firefox restored?

I am on Firefox v122.0 Google docs paste functionality doesn't work when using Cmd + v. This is happening only for Google docs. Same doc works perfectly fine on Chrome. I also tried running Firefox in troubleshoot mode with same results. Should I just give up on trying to make Firefox work with Google products.

Hi there,

Using up to date Firefox on a Mac, London UK. Recently returned from travel in Japan. The bank cards auto-fill stopped working & Auto-fill does not appear in Privacy Settings (it is not there – no need to request a check please:)?

Spent 2 hours on Mozilla support/community etc. No answers – including 'make a new profile'...(& why - won' that affect history etc)?

Would be very grateful for any help please?

With thanks,

Alex

macOS (and I assume Windows and Linux as well) supports local URL schemas. For instance, Apple supports the "applefeedback://" URL as a way to launch the macOS Feedback Assistance app.

If I have a link to this on a web page, or if I put it in a bookmark, Firefox will ask for confirmation and will then launch Feedback Assistant. This part works great.

But if I type that URL into the location bar, Firefox always sends it to my configured search engine. It doesn't recongize it as a valid URL. And in the popup list of suggestions, there is no option to just go there and not search for it. See the attached screen shot.

I don't want to disable location-bar searching altogether, because it is really useful, but I think there should be a way, on a case-by-case basis, to tell Firefox that I really want it to treat the entire text as a URL. The simplest approach is probably to have an extra row on the popup suggestion list that I can click on to open the text as a URL or produce an error if there is nothing in Firefox or the OS that can resolve it.

Hopefully this won't be too difficult to support. I think it would be extremely useful.

I am running v122.0.1 on a Mac and since the last update if I open a Facebook Messenger message which pops up at the bottom of the screen clicking the minimise or close doesn't do anything and the message stays on screen The only way to get it to close is to log out of Facebook and then log back in again. Is this a bug in this release?

I am using Firefox with the uBlock Origin and Cookie AutoDelete extensions enabled. When I try and load Gmail or any other Google site, I get a blank page and nothing loads at all. This only occurs when my VPN is on (I use Private Internet Access). However, even with the VPN on, Chrome will still load those sites. Disabling the VPN means that the sites load normally.

My guess is it might be some sort of privacy setting in Firefox, but I don't understand what it could be. The only thing that breaks/fixes the sites is connecting and disconnecting the VPN, irrespective of which country I try and connect from.

Google search no longer works on Firefox. Other browsers have no problems. Changing the default search engine on Firefox works (eg Bing), BUT. It can now find Google Maps, but Google Maps cannot find a location, because it uses a Google search. I tried the fix in about:config, but it had no effect.
