Firefox-Hilfeforum

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,

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?

Tell me how to reduce the size of buttons, tabs, and everything else BUT the fonts in my browsers. All of them have been affected. I've exhausted all of the normal "look in Settings and use your brain" options.

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.

I developed a web app that checks the existing session login for each new page. So, after logging in the first time, the user is shown a dashboard with a list of functions they can access (My Account, etc). When an item is clicked and the application calls the function, it first checks for the existence of login session. If it's not there, then the user is forced back to login screen. However Firefox is deleting the session at some point so when the session is checked for the new function, the user is forced to login again. Chrome, Safari, Edge do not and are fine.

Enhanced tracking is turned off for the site and is shown as an exception. What is happening and how can prevent it?

Hello. For a couple of months now I can't seem to be able to reproduce some videos on YouTube (depends on their format) and no videos at all on Facebook, for example. I have the same issue on both regular and dev versions. I tried many solutions from the forums but no success so far.

My OS is Linux Ubuntu 20.04. Browser and video drivers all up to date.

When I copy text from other websites, I'm not able to paste in the text field of Whatsapp Web. I'm using Firefox Developer Edition Browser in my laptop. But when I copy text from Whatsapp Web itself, I am able to paste in the text field.

This issue started happening just a few days ago.

Here are my specifications:

Browser: Firefox Developer Edition 117.0b8 (64-bit)

OS: Pop!_OS 21.10

Firefox crashes (tested in troubleshoot mode) for this URL : Link which causes crash https://developers.google.com/android/guides/opensource#java

There are no crash logs generated either (checked in about:crashes) . Attaching a post-crash dialog screenshot

Subject says it all, but it seems to occur with any site, anytime I try to open more than three or four tabs (ctrl-clicking links on a forum, for example) my Firefox instance grinds to a halt and starts consuming most of my CPU (Ryzen 5 3600).

I've tried turning off Firefox's various protections. I tried troubleshooting (formerly "safe") mode, and the problem isn't as bad but is still present as far as I can tell. The only extension I can think that would be making it worse is Tree Style Tab, but I don't know enough about interpreting Firefox profiles to verify.

The only reason I consider this odd is because doing the same thing in Chrome doesn't have this issue on this same device. If I open many tabs quickly, Chrome itself is still responsive. Those newly opened tabs may take a while to load and become interactive, but it doesn't affect the rest of the application. I pay my ISP for gigabit DSL, and as far as I can tell that is roughly what I get. In my case, Firefox doesn't behave this way.

Firefox is literally the worst browser now, im so sick of opening a new tab and seeing all these woke ass news on the homepage/ads. uninstalling this total piece of trash, if you use firefox you are [derogatory]

Hi, after updating to 118.0+ my MX vertical binding was changed to backwards -> Responsive design mode, forewards -> nothing or turning on add-on for bitwarden. I want back next and previous page feature. How to solve it? Thank you

I can't open Firefox. When I click on the icon Bing shows up. I downloaded the latest version of Firefox, I can't install it because I get the message that I have to close Firefox because it is running. How can it be? I haven't been able to open it for weeks.

I am on Firefox Developer Edition 120.0b9 (64-bit macOS). Using sites like whatismyip and whatismyipaddress, I am seeing that I have a VPN or Proxy enabled. When I use Chrome, I don't see this. I went through all the settings and turned off anything that could even remotely be related, and still get the same results. Does Firefox have a built in VPN that I am unaware of? Is there a way to turn it off?

Hi All,

I' m having the issue that .jpeg images don't zoom smaller in Firefox (they do in Safari). I'm performing cmd-+/- on a Mac keyboard.

Any ideas?

Thank you, Russ M.

In order to more convenient drag-and-drop interface, I need a fixed fixed space in nav-bar like Edge. For now we can add a flexible space on it. But it's flexible and it will disappear when I use a side window. And I can't drag over titlebar-buttonbox-container Please help me. Thanks!

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 recently upgraded graphics cards from an Nvidia GTX 1080 to an AMD 6900XT. Since then I noticed video stuttering on YouTube while playing 4k videos, especially noticeable at 4k/60FPS (example video ). Prior to the upgrade, I was not experiencing issues.

I monitored task manager as the video was playing to see CPU usage, which was sitting at 25% (4 core 8 thread CPU). GPU usage was fluctuating from 1-3%.

I tried resetting all the changed configuration options in about:config, removing all add-ons, "Refreshing" Firefox, and ultimately uninstalling and reinstalling. Nothing has worked so far except for "Troubleshooting mode" in about:support. In that mode, I experience no stuttering and GPU usage rises to 25-35% with the video playing, even before I reinstalled.

This most likely isn't a networking issue as the "Stats for nerds" option on the YouTube video shows I have 10-20s of buffer while the video is still stuttering.

I would like to find out what's different about Troubleshooting Mode that is not giving me the same problem while in "Normal Mode". Any advice?

I had set up a userContent.css file in the past to pull up and fetch an image on my computer to display as a background on the homepage. It worked and did it's job until recently, when I had recently relocated a lot of my files around on my computer. I have redirected everything to where I want it to look, including the userContent.css file to the new location for the image I want as the background. Firefox loads the .css file correctly, and recognizes the file existing, but it won't load the image itself for some odd reason. It states it "may not load or link the file" because of a security error, and thus, can't load the image. I never had to deal with this before. How can I get Firefox to be able to load my image like I want it to? I have screenshots that I can provide, but this site doesn't want to upload them at the moment.

I've been using Firefox Developer Edition for the past two years without problems. From some point on(about 1 week ago), All browser's search functions suddenly don't work. Navigation bar? Not work. Searchig from Bookmark? Not work. Do not use google? Not work even with duckduckgo. with out DNS? Not work even with 142.250.206.206. There is only one website that i can access with Firefox Developer Edition. It is Mozilla's official website At this moments, I curious that "why isnt work>?" So i used Developer tools, And then I found something amazing. There was no request or response on the Network tab! (Of course, I pressed Ctrl + R) And then, on second thought, I found that the JS function that should have been small in the lower left of the browser screen was not displayed. Finally, I thought, hmm... My Firefox is broken! So i found the FireFox, and then i uninstall it, and reinstall it! All the External Plugin works, OK then What if FireFox????? Unfortunately, Firefox Developer Edition's problem remained the same. I'm sorry that i couldn't even give you a possible cause of the problem. But i SUFFER for a week! Please resolve the issue.....

I don't know why the page https://encuestas.msssi.gob.es/limesurvey/index.php/438579?lang=es is marked as insecure in Firefox. I tried in Chrome, Edge, IE... and the page is marked as secure, the certificate is recognized.

I attach screen captures of Firefox and Edge examples.

I've the security.enterprise_roots.enabled setting enabled.

If I check for Firefox error details, I see (auto-translated to english): https://encuestas.msssi.gob.es/limesurvey/index.php/438579?lang=es The issuer of the other end's certificate is not recognized. Strict HTTP transport security: false Setting HTTP public keys: false
