Firefox Community Forum

I have the HTTP_PROXY, HTTPS_PROXY and FTP_PROXY (and their lowercase counterparts) exported and then the firefox binary is started from the shell script. The settings in firefox say it will 'Use system proxy settings'. Nevertheless I do not see the proxy being used as I can not access the web pages that need the proxy. The 'about:config' also does not show that firefox picked up any proxy related information from the shell environment.

I know the proxy address is correct because if I use brave browser instead of firefox (same shell script that launches brave) I can reach the web pages behind the proxy as expected.

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.

Twice in the past 2-3 weeks I have had to restart the computer, Linux Mint 21.2 Firefox 124(when updated in the past couple of days), due to the mouse freezing up and not being able to move the mouse on the screen. That's not the current problem, but it might help direct things to the final solution.

After the most recent reboot last night now I'm having a rather problem. The up/down arrow keys are no longer scroll me up and down a webpage like they always have in the past. Instead of doing smooth scrolling like they always use to, now they are scrolling me up and down the links on a web page. For example, if I were to be on youtube it would first want to scroll me down the left side links before taking me through each and every video link, when the page goes to load in more videos than it wants to go back and scroll me down the left side links again. It acts like it is taking me through the html code, line by line, instead of scrolling me smoothly down the webpage. The only way I can scroll smoothly down the webpage is to use the mouse on the scrollbar on the right side. It does this both in normal mode and in Troubleshooting Mode.

I have checked and beret scrolling is false as well as beret_shortcut. Use autoscrolling, use smooth scrolling, show scrollbars and always underline links are all clicked on. Always use the cursor keys to navigate within pages is unclicked. I have tried different changes between clicking on and unclicking those options with no change being noticed.

How can I get this back to the way it used to run?

Hi,

I'm using Duckduckgo as my search engine, but when I type in a search string, it Firefox prepends it with https://html.duckduckgo.com/html/... This opens a search page that doesn't follow my dark theme. When I click on a link, another link is added that creates a link back to the same URL, causing a loop. This never happened before I upgraded to Ubuntu 22.04 & the latest version of Firefox, 100.0.2. How can I change this back?

Thanks!

Hi there,

On Firefox, I'm experiencing "momentum" scrolling where, when I scroll using the trackpad, after I lift my fingers off, it keeps scrolling for a bit.

This is not the same thing as smooth scrolling. Disabling smooth scrolling does not disable this behaviour, and I use smooth scrolling on plenty of programs without it experiencing this "sliding" "momentum" on any of them except Firefox. I've also used Firefox before with trackpads without experiencing this.

How can I disable this?

I am running Firefox 126.0-1 on an Arch Linux system. Most websites are failing to connect for security reasons.

Some sites, including google.com and nytimes.com, fail with an "SEC_ERROR_UNKNOWN_ISSUER" error, and their certificates confirm that they are respectively issued by Google Trust Services LLC and DigiCert Inc.

The website archlinux.org errors with "MOZILLA_PKIX_ERROR_MITM_DETECTED", stating that "Software is Preventing Firefox From Safely Connecting to This Site", citing in particular ISRG Root X1 as the problem. The certificate confirms that it is issued by Let's Encrypt.

The website duckduckgo.com simply errors with "SEC_ERROR_PATH_LEN_CONSTRAINT_INVALID" and states "Secure Connection Failed"

I have confirmed in preferences that my proxy settings are set to "No proxy" and the problem persists across troubleshooting mode and making a new profile. I have also tried removing the cert9.db file in a given profile folder.

Please, how can I disable the tab title on hover? After they appear, they stay on the screen even if I switch windows and are extremely annoying. (Work on fedora, gnome)

Dear Technical Support,

I'd like to report a problem which affects the rendering of websites in Firefox with a HiDPI monitor.

I'm having issues with the text and graphics of web pages, that are often mismatched or misaligned, with text being too large compared to graphical elements. See the enclosed pictures for an example; as you can see, this happens also on your website. Also, I've noted that pages (and plugins) appear to be "shrinked" as opposed to when viewed on Chrome, where they are shown to their true size.

Setting ui.textScaleFactor=100 and tweaking with layout.css.devPixelsPerPx did not change much. I must admit that I find this behavior quite strange, since HiDPI monitors have been around for more than a decade, and especially considering that this did not impact my experience with Firefox on Windows, using the same monitor and machine.

I hope to find an effective solution to this problem and look forward to your reply. Please let me know if I can be of any help in this matter.

Best regards, Federico

I am having a hard time getting accustomed to the Firefox scrolling experience. I am only using the touch pad and the touch screen. When I release the finger the time it takes for the scroll speed to come to a halt is way longer than on Chromium browsers and uncomfortable. I want to configure this to decelerate faster or to remove the smoothing completely.

I have tried playing around with scroll configurations and I found that setting apz.gtk.kinetic_scroll.enabled =false disables smoothing correctly, but only works for touch pad, not for touch screen.

- Is there some config I am missing to disable this kinetic scroll using touch screen? - Is there a preference where I can halve the time it takes to decelerate, rather than disable it completely?

I am running Ubuntu 22.04 on Wayland if that makes a difference.

Hello, trying to verify the integrity of firefox-118.0.1.tar.bz2 I realized the GPG key has changed.

The following blog post details the change and shows the new key: https://blog.mozilla.org/security/2023/05/11/updated-gpg-key-for-signing-firefox-releases/

But when I download the key using the link provided (which points to keys.openpgp.org) the key I get is different from the key posted on the Mozilla blog page.

What is even more strange, is that the key from keys.openpgp.org declares in the comment that 14F2 6682 D091 6CDD 81E3 7B6D 61B7 B526 D98F 0353 is the fingerprint of the key (the same that is posted on the Mozilla blog) but it can't be because the key different.

So my questions: 1) Why Mozilla is posting a link to a key that is different? 2) Why keys.openpgp.org shows the correct fingerprint with a different key?

And, in the end, which key should I trust and why.

Thanks.

Every time I open Firefox after closing it, I get the message below. I can click the button to restore session and it works every time. With each update, I hope to never see this message again, but after installing a new version on Ubuntu today, I see the same familiar message. This is not linked to a computer, or an operating system because I've seen this on both Ubuntu and Mac. If Firefox could literally just click the button that would be awesome.

Sorry. We’re having trouble getting your pages back.

We are having trouble restoring your last browsing session. Select Restore Session to try again.

Hello,

I have a problem with Firefox on Linux, doesn't seem to be distro specific as I've tried Manjaro/Ubuntu/Neon, when using KDE in that when listening to music on YouTube music my computer will go to sleep after the elected time. On KDE you can see which applications are preventing sleep and/or screen lock, other applications are listed here but not Firefox.

When playing a video everything works as expected.

I would investigate myself, but I don't know where to start so if someone can point me in the right direction or offer any insights?

Currently using: KDE Neon KDE 6.0 Kernel 6.5.0-21 Wayland

Is there any way (or any addon) that I can insert commonly used text into a text box? I have tried AutoFill and, while it works fine for... well.. filling out forms... I cannot get it to work for what I need. Basically, I want to insert things like '¯\_(ツ)_/¯' rather than having to go to a page, select that, copy it, go back and paste it... or, worse yet ... remember and type that over and over again.

I upgraded my version of Firefox from an ESR version to v129.0.1 on Debian 12. Drag and drop of files from the desktop or the file manager (PCManFM-Qt) into the browser stopped working. It is still working properly in Chrome.

This occurs with several web apps but, as an example, it occurs when trying to drag a jpeg into Roundcube Webmail while composing a message.

No browser console errors are genrated when trying to do this. It occurs in Troubleshooting (safe) mode as well. In apps that pop-up a "Drag files here" target, that target still appears but dropping the file on it does nothing.

So I was sent a picture in .heic format. Trying to open it FF entered an endless loop opening new tabs with names like: "/tmp/pid-949/IMG_9409.heic". There was no easy way to stop it, the 'X' button did nothing. It opened hundreds of tabs. I had to kill all my tabs to get rid of them. BTW there's supposed to be a 'Recover Previous Session' button in the main menu. Not there. On line, I see several different images of what my main menu is supposed to look like but mine is nothing like that. I have 115.6.0esr (64-bit).

I currently use Chrome on Android & Chromebook as my main browser, but I would like to switch to using Firefox now across all my devices (linux, android, chromebook). To do this, I need to import my passwords from Chrome to Firefox, and have them sync between the Firefoxes on all of my devices, but it's not working. I have tried the following:

Method 1: I installed Chrome on my new Linux machine. Checked and made sure it had synced my passwords by logging into a website using Chrome. Then, on Firefox, I pressed alt to enable the toolbar, then File->Import from another browser. The pop-up says "No programs that contain bookmarks, history, or password data could be found."

Method 2: Chrome seems to have a feature to export the passwords to csv. So I exported the passwords from Chrome to a csv on Linux. To be thorough (because I am having trouble getting this to work), I used accounts.firefox.com to sign out the Firefox on my android phone and chromebook, then (on the phone) I deleted my browsing data, uninstalled firefox, and rebooted the phone. Back on Linux, I did about:config, then set signon.management.page.fileImport.enabled to true, then did about:logins then menu->"import from a file", selected the csv that I just exported from Chrome, and clicked Import. Import Complete, 332 logins added, 1 not added because it was missing a password. Logins successfully imported, hooray! For testing purposes, I create a unique new password entry, http://foo.com username "a" password "b". Then I go to about:preferences, make sure that syncing is on and I'm currently syncing logins and passwords, and press "sync now". Log in to my phone, install Firefox from the play store, start it up, sign in using my email and password (it says "syncing"), go to logins and passwords, click "saved logins". The only one listed is for foo.com, the fake one I created to test the syncing, but I expected to see all 333 there.

How do I get this to work?

How to save images to the downloads directory (that I chose in settings) without using right click -> save image as .. -> popup window .. then choose the location where I want to save it.

I tried alt+click, it didn't work, it saves the webpage url instead of the image. I prefer a solution that does not involve any add-ons.

OS: Pop!_OS 22.04 LTS Firefox version: 121.0.1 (64-bit)

Thank you.

I need to connect to my employers Citrix portal tot start a Citrix session for my daily job. The problem is that when try to login using my credentials nothing happens except for the loading icon of Firefox that keeps "spinning" (see image).

When I do the same in another browser, like Chromium for example, everything works fine.

I already tried the following steps:

- Installing an older version of the Citrix Workspace app - Reinstalling Firefox - Disabling the blocking extensions

I am using the following versions of components:

OS: Linux Mint Vanessa 21 Citrix Workspace app: 24.5.0.76 Firefox: 129.0

Other colleagues report the same issues when using Firefox whether in Windows of Linux.

Any help would be much appreciated?

After upgrading to fedora 40, firefox just takes ages to boot up, even when it's running if I want to open a new window it still takes ages to run. I have tried uninstalling it and deleting it's data but with no luck. The issue still presists.

Using arch's latest version. I recently upgraded my firefox version to 117.0, and can't play any videos from different sources.

The image freezes and is in an eternal buffering state.

I tried downgrading to 116.0 and 115.0, and the issue persists, so it doesn't seem to be related to the latest Firefox version.

So far, I've confirmed the same issue in YouTube and Twitch.

On Twitch, the videos are super laggy. The image freezes, then moves to a different scene, freezes again, and then the same thing over and over.

On YouTube, it always shows as loading. If I try to move it to play a different time in the video, it works for half a second and then freezes again.

The issue still occurs if I try incognito mode, troubleshoot mode and refreshing Firefox. I already tried disabling hardware acceleration (https://support.mozilla.org/en-US/questions/1206076) and have no more ideas or options.

Thanks in advance!
