Firefox Support Forum

After an update today, private browsing windows now are a different color than the other windows. I don't want them to be a different color. How do I change them back to the same as the other windows?

Also, how do I remove the extra text label next to the private mode icon, and just generally put things back to the way they used to look?

Hello, This issue might or might not be related to [other issue] I have since I updated Ubuntu 20.04 to 22.04 and therefore updated my Firefox to 104. I can't login anymore on Letterboxd since the update. It's not a problem of username or password. When I click "Sign in", nothing happens except a page refresh, but I'm still not logged in. Other strange behaviour on that site since the update: most of the images don't appear. For example on this page : https://letterboxd.com/films/# all the movie covers are just blank.

The website does work properly when using Firefox in private mode though (both login and images work fine), so this makes me think it's related to my other issue mentioned above.

OS: Ubuntu 22.04 Firefox 104.0.2

EDIT after posting this question: I just found out that I can't login on Google either. I enter my username, password, then it asks me to validate on another apparel that it's really me, which I do, and nothing happens so I can't login. It works normally in private mode.

Hey there,

Intro: I recently switched to Linux and (because Brave is so broken) also to Firefox and I am liking it so far.

Problem: Unfortunately I can't copy-paste files from Ubuntu Files (Nautilus) to Firefox (I tested image files and also sounds files, neither is working).

Test with Firefox: 1. Download a random photo (e.g. from Unsplash) 2. Select the file and hit ctrl + c in Files/Nautilus 3. I go to the clipboard inspector 4. I hit ctrl + v 5. The image does not show up in the output (see screenshot)

Test with Brave: 1. Do the same as above 2. The image does show up in the output (see screenshot)

Notes: - I am using Linux Ubuntu 22.04 with Wayland - Firefox Version 107.0 (64-bit) for Ubuntu Canonical - 1.0 - I have no extensions installed - I am not using the snap version (so I can scroll smoothly) ... I think I used apt-get install but not 100% sure

When clicking on a link to an .mp4 file, Firefox navigates to a builtin video player, streaming the remote video file. When Firefox is unable to stream or display a file (as is the case with .mkv or .txt for example), it is downloaded instead.

I simply want .mp4 files to be downloaded when I navigate to them. I tried setting `media.mp4.enabled` to `false`, and that worked, but it also disabled most embedded media players.

Hi, I create an account to sync Bookmarks, Passwords, Add-ons, History etc from one computer to an other. I successfully created the account, verify mails, checkbox all features to sync in settings, and click on "sync' multiple times. But nothing is synced on my new computer. On the log I saw (about:sync-log):ab

1. 1. On new computer side

Can you help me please ? Mrs RICHTER

Currently Firefox is redirecting http://localhost:8080 to http://localhost:8081 , each time when type the address in the URL address bar.

I have been working with a container wordpress. I have tested in chrome the address http://localhost:8080 and all works fine.

How can we fix that problems, thanks in advance.

I have removed cookies and site data of localhost in Privacy-and-security> Manage-data>

This site, Costco Instacart, worked perfectly with Firefox as recently as April 15, 2023 but today fails (see attached image): https://sameday.costco.com/store/costco/storefront?zipcode=11021

Cloudflare believes it is protecting itself from online attacks when accessed by Firefox. The same site worked perfectly today, on the same computer, using Google Chrome.

Cloudflare is a major CDN and many important commercial sites, like Costco Instacart, have their content delivered by Cloudflare so this is a major issue with Firefox. For the moment there is a work-around, use Chrome instead, but it would be better to have Firefox address issues with Cloudflare.

I am running Firefox on Mint Debian edition, I find the Youtube playback very low volume preset at about 1/4 of max, I try set it to the max but it returned the same after restart. I start FF in trouble shooting mode to disable theme and extension but didn't change thing, I remove and reinstall FF also did not help. I find something strange that, on the Help menu it said the updates disabled by system administrator but I did not do that, it is now on 116.0 64bits, any comment ?

Expected: Firefox displaying all known Unicode characters.

Result: Many characters missing.

Failure page as an example: https://en.wikipedia.org/wiki/Religious_and_political_symbols_in_Unicode

Description: I tried going through a Unicode list Unicode list and the extensive set of characters displayed correctly. However, when reaching further into character sets as shown in the failure page page, many are missing which are not new.

• "Repair encoding. . ." button was not active.
• An encoding switch extension was not able to resolve the issue.
• Troubleshooting mode did not show changes.
• Switched fronts available such as Noto Sans and Roboto Sans without success. Possibly a font failure?

Previous versions of Firefox allowed scroll wheel button clicking to open links. I noticed that the latest version doesn't allow this. Ctrl + left click works as normal but not the scroll wheel clicking.

I am using firefox v104 on linux mint. This problem happened this evening. Every tab i open shows the same error.

I tried the solutions suggested in other similar forum posts like >safemode (tabs still crashed) >driver update (my drivers are up to date as far i can tell) >deleting cache and reinstalling firefox (tabs crash). I took a backup of my bookmarks and extensions as suggeated in another forum post. > one youtube video (https://youtu.be/F9VaXwSB_po) suggested toggling media.cubeb.sandbox in the config section. The tabs started loading after that but it wasnt that useful as i wasnt able to get any videos to play in the browser.

Also, i don't really know if the issue is related, but chrome tabs were also not loading or responding ('Page unresponsive' error).

Please help. Thank you :)

FF keeps replacing

http://mysite.domain.net:3344 with httpS://mysite.domain.net:3344

whatever I try to fix this behavior. Thing is that I own this server and there ever was't any SSL implemented. I mean this - never.

Other browsers (Chromium, Chrome, Opera) don't take such a forcing action, website opens like a charm. Why FF thinks it knows better which URL I really want to open?

I already googled _a lot_ in order to find solution, but no one worked.

Setup: Debian 11 Mate no proxy and no separate "internet security" stuff on laptop (other browsers with default settings confirm that) FF 102.11.0 ESR 64 no addons (all switched off)

already tried: browser.urlbar.autoFill false browser.cache.check_doc_frequency 1 network.stricttransportsecurity.preloadlist false browser.fixup.fallback-to-https false dom.security.https_first false

What else I could do to stop this madness? Thank you in advance for any help

A long time ago, I saw a list of open tabs in all windows, not just in one window, as it is now. (By the way, Google has added such a feature to Chrome. Clicking on the arrow allows us to see any open tab and navigate to it.) I am currently using Tab Manager to search for a tab. But the tab manager is not the best option because it is too slow to open and requires too many resources. Can I restore the old behavior to see tabs in all windows?

I'm trying to use Microsoft Teams in Firefox because the native app for Linux is abandoned and crashes, and at first sight the app is blocking Firefox on purpose. Buttons to make calls are disabled, stating that audio and video are not supported in my browser, but everything works normally if join to existing calls using e.g. links.

Is it possible to trick Teams to think I'm using Chrome? I found the "User-Agent Switcher and Manager" add-on, but I can't figure out how to possibly use it.

Setting `widget.non-native-theme.enabled` to false no longer works; I still get Firefox's default styling for controls and widgets.

I use a custom GTK3 theme in my environment that I want to apply to Firefox. The above setting works in 91 ESR, and broke with the upgrade to 102 ESR.

A custom user chrome stylesheet would be too painful.

Note: You can revert page styling to defaults in View -> Page Style -> No Style.

Hello,

I have more than 30 extensions, but I cannot add an extension shortcut into my toolbar and no extension appears in the “Customize Firefox” view. I tried “Restore defaults” without any effects...

There is a way to fix this issue or run Firefox in verbose mode to more information why my extensions don't appear here? (Other than restart from a new fresh profile if it's possible…). I confirm that all the extensions are functional and activated. Thanks,

Emeric

Hello Volunteers,

Ubuntu crashes while moving around a Firefox tab with a mouse, IF the mouse cursor goes thru the top bar of the laptop screen. I am using Firefox V 113.0.2, Build ID: 20230522193126 on Ubuntu 23.04. This could be an Ubuntu problem or a Firefox problem.

Thanks Dilip Deodhar

i am using latest firefox (106.0.5, snap) in ubuntu 22.10 64 bit. i have set ubuntu network setting to manual and have set socks proxy there (socks host: 127.0.0.1 port: 2345). while other browsers can connect through system socks proxy, firefox is unable to connect it. i have changed and tested different configs in firefox network menue but no one was helpful. i have also try to solve the problem using foxyproxy addins but it does not correct as expected. sometimes it connects and many time it does not. what is the firefox problem with socks proxy? how can i solve that? thx.

Dear community,

As I use a few self-made unsigned add-ons, for several years now I have been using the Firefox unbranded builds on Linux with great joy. In the past these became available for download shortly after a regular Firefox was released. Lately though things have changed. The current latest release for unbranded is stalling at version 107. So it's getting further and further away from the official Firefox, which is at 109 at the time of writing.

Obviously I'm concerned my unbranded Firefox is not getting the same security updates any longer. I do realize there's alternatives for supporting unsigned add-ons. Running a Firefox nightly or developer-edition is something I'd want to avoid, so for me these aren't real alternatives. I've also tried tracking unbranded info on bugzilla.mozilla.org, but couldn't find anything relating to this 'lag'.

Where can I find more info on this topic? Are these unbranded builds being discontinuated?

Thanks for reading, keep well!

Why does the Mozilla Firefox snap for Ubuntu keep changing the value of browser.opaqueResponseBlocking away from the default and selected FALSE setting to TRUE? This makes Firefox nearly unusable since the streaming video keeps being cut off when Mozilla Firefox snap for Ubuntu keeps changing the value of browser.opaqueResponseBlocking randomly during use. Specifically this is the 116.0.2 (64-bit) Mozilla Firefox snap for Ubuntu canonical-002 - 1.0 that is installed with Ubuntu 23.04. Please advise.
