Firefox Support Forum

Hello.

It seems I get a problem or two almost always with a new update lately. I have been using an userChrome.css to reduce the width of sidebar but the latest version 107.0 now ignores it and have a wide width even at the narrowest. Mine currently is set as, "#sidebar {min-width:30px !important; max-width:none !important;}" This no longer works. Your support much appreciated.

Regards,

So I downloaded Firefox and logged in expecting my bookmarks to carry over after I "sync'd" it, however the did not. So I went to my old pc and did the export bookmarks thing and imported it to the new pc.

Now.. I have all my bookmarks and everything appears great. Except whenever I open a link from say my work it opens a Mozilla window that doesn't have my bookmarks. When I try to combine the windows It doesn't let me. I am also scared of losing access to the Mozilla with my bookmarks as I work from home using those. (the desktop shortcut to Mozilla opens the one without all my work)

In the attached screenshot things to note, the bookmark bar available on left isn't there on the right. Additionally in the taskbar (bottom) it shows Mozilla in two distinctly separate icons. When two Mozilla windows are open, they share the same icon on the taskbar, these do not, which leads me to believe I have two incompatible versions existing next to each other.

FireFox V. 107.0 -MBP-High Sierra.

Lately the last couple of months when I google search webpages then select them, Fire Fox doesnt bring up the article, Its been happening a lot and getting really irritating. So I bring up Google Chrome and it always brings up the article. SEE THE PICTURES. I use only Fire Fox as my browser, I keep Chrome around for when Fire Fox doesnt want to work properly. As you will see in the pictures the same website for both browsers. Fire Fox wont show the article no matter how many times I refresh the page or shut FF down, or reboot my MBP, but Chrome works perfectly every damned time. Why cant Fire Fox open the article but Chrome can? I need your help, any advice is greatly appreciated. SEE THE PICTURES.

Is there any way I can completely disable horizontal scrolling? I'm using a laptop with a trackpoint (lenovo x230, Windows 10) and it's not terribly accurate, which means scrolling whilst a youtube video is going often makes it track backwards or forwards, and another website I use uses a horizontal click to send me to the next page, which sucks. I would prefer to just be able to disable it entirely. Thanks!

I swear to god I used to have it disabled, just need to work out how again.

Since upgrading to Monterey, Google search pages show almost no text in Firefox. Google searches in Safari and Google Chrome are completely fine. Only Firefox is showing the problem. The blank text includes dropdown menus too - all options inside them are blank. Currently on Firefox v107.0, but the same problem happens with older versions.

If I go into Troubleshoot mode, the Google searches are working fine. I have refreshed Firefox, Cleared the startup cache. But the problem persists. I uninstalled Firefox from the machine, restarted the computer. Did a fresh download and install, haven't signed in so there are no addons/extensions to cause problems.

This is happening on both an Intel Mac and an M1 Mac running Mac OS 12.6 Monterey.

I attach one screenshot showing the same page with and without troubleshoot mode on. The second screenshot shows another page of results including what looks like weirdly encoded characters.

I've followed all the suggestions in the support page but nothing has helped. I'd really appreciate any advice on further troubleshooting. Thanks in advance for any help.

Clicking the mousewheel still works, but scrolling doesn't work. This behavior occurs on tab bar as well.

Using option "Restart with addon disabled" from about:profiles can make the mousewheel scrolling work, but manually disabled all addon and restart just won't solve it.

I use the Windows registry FontSubstitutes (Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes) to replace system fonts like Segoe UI with other fonts. It takes a lot of work to get Windows itself to respect these options, to the extent that I have to make it believe Segoe UI isn't present by modifying a different registry location (Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts).

However, Firefox does not respect the FontSubstitutes settings. Based on a previous post here, this is something it did prior to Firefox 89, but has stopped doing.

An ideal solution would be a way for Firefox to correctly read my FontSubstitutes settings. An acceptable workaround would be a way to provide Segoe UI for Firefox to use while still preventing its use in other applications. (I know that, for instance, Adobe Photoshop allows users to install fonts to Photoshop itself, bypassing the system fonts folder entirely.)

I upgraded Firefox to 109.0 on OpenSUSE Linux today as an update. Firefox no longer plays videos. Chrome is still playing the videos, so the codecs are on my machine. Is there anything I can do to fix this?

Firefox Developer Edition - Developer Console is killing my productivity. It started opening in Full screen mode about a week ago and will not exit full screen. I have to F12 and exit developer console. This is a major issue because, I work with the console not docked. Docking blocks my productivity. F11 only puts it into some very weird outline mode where all I see is a rectangular grey outline on my full screen. If I click on it, it repaints the console in full screen. There is no option to drag and expand or contract. Nothing. Nada. Please help. This is my primary browser, er -was my primary browser. I'll continue to work around it until my patience is completely exhausted. Almost there now.

Sorry about the terrible markup on the screenshot. It's hard to encircle a big gray full screen empty frame. Thank you.

Lately in Google Drive I get this error when I select one image or a file: Impossible load details. Retry. I have Firefox 108 version, on Edge and Chrome all is OK. Also the troubleshoot mode doesn't resolve the problem.

I am using Firefox Developer Edition Version: 110.0b5 (64-bit) on M1 Mac running Ventura 13.1.

I am building an webapp some XHR triggering in background but it is not necessary to run the application (running fine on other browsers). But on Firefox Developer Edition, It shows a error window with the message and stops loading the application.

Firefox can’t establish a connection to the server at localhost:4000.

localhost:4000 is the failing XHR request domain. I have attached the screenshot.

How to ignore the XHR failing errors just like other browsers?

The blocks where code should be displayed like on screen and on stackoverflow displayed in a weird manner : replaced with [Object object] i don't have any extensions that might cause that

I recently installed new pc with fresh Firefox Developer Edition. Then I transfered the profile folder from old pc to the new pc. All bookmarks, addons, etc is there. Just the XULRunner popup appears only on the new pc. I uninstalled firefox on the new pc again and reinstalled it with profile cleaning. After profile cleaning firefox got faster and addons got removed. But the XULRunner popup keeps appearing. When I go to taskscheduler and trigger the "Firefox Developer Edition Background Update CA9422711AE1A81C" again, the XULRunner popup appears. Removing this taskscheduler and Firefox keeps readding it and the XULRunner popup are back. Any idea how I can get rid of the XULRunner popup?

Hi,

im getting unknown issuer on my thin-clients with a FF ESR 45.9.0. This FF is tied to the OS (Ubuntu 16.04) and the OS is the most recent compatible version for our version of the thin-clients. So yeah its super old and I'm not able to update any of this. There is no security.enterprise_roots.enabled option available. What would be the best way to solve this issue for ~400 clients. Thanks in Advance Regards Tekkion

Hi lovely People, I try to setup 2FA on accounts.firefox.com with Authy on Android. In Step 1 the code generated from Authy is accepted.

But then, in step 3, when I try to paste in the just in step 2 provided backup activation code, it tells me it's wrong. Am I stupid? I just copied that key from step 2 ... I tried it many times now. Checked if my clipboard is working as expected, tried to delete the spaces in between... I used FF Standard and FF Developer Edition. My Authy is working elsewhere.

Any help? I searched the Forum, found some relating questions, but they never get answered. No one having the same issue?

Hi, I use the Firefox Developer Edition for Windows Desktop (112.0b4 (64-bit) on daily basis. When I play the Udemy DRM content nothing goes wrong first and the browser loads the page well. But after some time passed I see that Firefox stops to load the page and the tab spinning infinitely. Pressing the realod button doesn't help. The only solution is to restart the browser. I use no-proxy setting. The refreshing of the browser didn't help either. I have configured the following options in the "about:config" but it didn't help as well: network.dns.disableIPv6 : true network.dns.disablePrefetch : true network.http.http3.enabled: false

A lot of the images appear broken, see the images attached(left is FireFox, right is Chrome) Only happens with Mozilla browsers, nighty, beta, regular, I've tried them all Reinstalled countless times Hope that someone will help me with this

hello guys I need help with this problem in firefox developed edition

Specifically, when I use the Inspector panel to inspect elements on a webpage, the selected elements are outlined with a blue border instead of being filled with color. This is making it difficult for me to visualize the layout and styling of the elements, and I would prefer to have them filled with color instead.

I have tried to find a solution on my own by searching online, but have not been able to find a clear answer. Could you please advise me on how to change the settings in Firefox Developer Edition so that the Inspector panel highlights elements with a fill color instead of just an outline?

Is there any way I can make Firefox address bar autocompletes the full URL (https://bitwarden.com/password-generator/ instead of https://bitwarden.com/)?

Firefox 114b5 does not remember form history. I have tested two different websites.

I have form history enabled - see attached browser_settings.png. Attached is a screenshot of the moz_formhistory table in the formhistory.sqlite file.

What do I need to do to enable form history on all websites?
