Firefox Support Forum

Hi,

I'm on Arch Linux and use uinput to create key events. It works reliably for >12months in all applications and under all circumstances except in Firefox where some key events are skipped non-deterministically. My test case is:

in a text field, emit `<ctrl down>a<ctrl up>123456789987654321<left>...<left>` with 9 times `<left>`. Sometimes a 9 is missing and sometimes the cursor is further to the right than expected.

This happens every 8th try or so, which is too frequent to not break the user experience.

What I have tried: - multiple PCs (2 with this issue and 1 without) - Troubleshoot Mode - `window.onkeydown=(e)=>console.log(e)` (events are missing)

Since I've only ever seen repeated characters/keys disappear and never when writing manually, I would guess there is some kind of event cleanup algorithm kicking in. (the events are emitted without any delays)

I would really like to fix this issue because Firefox is my favorite browser. Any idea how to track it down?

Firefox used to have an option to put tabs back under the address bar, it is missing. I don't want to mess with custom css files every update when mozilla breaks things again.

Very recently, I was typing a ton of content into a website textarea, when my Firefox Nightly install crashed. I lost all of this work from hours. Is there any way to get access to this data?

Firefox seems to crash repeatedly and generates no crash reports, just freezes up my pc. It works in troubleshooting mode but even after refreshing, the problem persists. Surprisingly, it will consistently crash if I go to `about:support` (except in troubleshooting mode). Any help would be appreciated!

If you drag text onto a Firefox window, it interprets that text as a URL and goes to that page. This is a problem because the only time I drag and drop text onto a Firefox windows is a password from my password manager. If I slightly miss the text box, it interprets the password as a URL and tries to go to it. This (a) Does a DNS lookup of the password. As there usually won't be a valid extension, I expect this only gets as far as my router, but it's still not ideal. (b) The page I was on has now gone, replaced with the "Couldn't connect to server" page, so I need to start again. Usually this is just a login page, which isn't a massive issue, but if it's a registration page I lose all the data I'd entered on that page, and even if it is just a login page, some badly implemented sites can lose information if you step out of the workflow.

In Google Docs, my text cursor will randomly bounce backwards on the page if I perform certain actions, such as pressing Tab in a bullet point list to create a subitem, setting the text to italic, or sometimes just clicking the cursor to the end of a document. Sometimes reaching the end of the line is enough to make the cursor jump back to a random position on the line.

I have tried this in a new profile with no addons and the problem persisted. I could not confirm this in Chromium last I tried. (But I swear I remember it happening in Chromium once or twice before) I have confirmed it on my PopOS laptop and my main PC booted into both Linux Mint and Windows 10.

I am running Firefox version 116.0.3 (64-bit).

Hello,

I need help i'm using polish language always on many websites.

When i typing letter "ó" which using key combination Right ALT+O always my brower opening "Open file" dialog window. this is annoying always.

Many sites write that it can not be changed?

Why does the browser open this dialog with this shortcut when there is another shortcut for it? Ctrl+O. Why two another shortcut doing te same job?

I am running Firefox-112.0(64bit) on Debian Bullseye. When I pend Firefox I am presented with a blank page rather that my normal sign in page.

Opening a terminal window and starting Firefox with /opt/firefox/firefox generates the following errors:

comp@AbNormal:~$ /opt/firefox/firefox [GFX1-]: glxtest: VA-API test failed: no supported VAAPI profile found. ATTENTION: default value of option mesa_glthread overridden by environment. ATTENTION: default value of option mesa_glthread overridden by environment. ATTENTION: default value of option mesa_glthread overridden by environment. ATTENTION: default value of option mesa_glthread overridden by environment. [ERROR glean_core] Error setting metrics feature config: Json(Error("EOF while parsing a value", line: 1, column: 0))

If I enter a URL the page opens and is usable.

How can this problem be fixed?

Thanks in advance.

I want to navigate on search results using the keyboard. I could use tab but it suggests all interactive elements such as news, images, books, videos, search settings and etc one by one. I want to press something and make active first result, then second. If such hotkeys are not provided, maybe there are any extensions with similar functionality?

been at it a week everywhere. how can I change the resresh rate about 60MH. desktop preferences is greyed out. command line didnt do it. not a programmers, please keep it simple. was hoping a GUI would make life easier. its blocky on a slow screen scroll. tried loads everywhere. I think it might not happen in chrome.

Hello I use webrtc to organise online calls and, for some time now, I've noticed that I'm getting echoes on Firefox whereas in the same situation (same output/input) I'm not getting any on Chrome...

I've tried looking at the getUserMedia level by changing the following parameters: **echoCancellation**, **autoGainControl**, **noiseSuppression** but that doesn't change anything.

I have the impression that this is due to the latest browser update...

No problem with chrome.

Any ideas ?

Thanks

Hello everyones,

My firefox on my ubuntu give me to "bug" :

first "The bookmarks and history system will not be functionnal..." second, when i try to sync sign up : "error 500"

What i have try, "rm -rf .mozilla .cache/mozilla" i have download latest version and execute "firefox-bin" i have try to chmod 777 all this folders and under folders...

i'm working on it from three hours and have read many solution on firefox support or others website, no one works...

So can you help me ?

I'm the tech director (tech janitor) for a public school that is using Securly.com for their Internet filter. Securly requires installing their own certificate so they can be a man-in-the-middle. I've installed that cert into Firefox and that works fine. However, even with that cert installed, Sync doesn't work when I'm behind that filter. As soon as I take one of my computers off the school network, everything will sync up. I don't get any errors that sync is failing, it's just not working. Any ideas on how I can fix that issue?

Thanks!

I've been having an issue for a while now where the cloudflare challenges that ask you to click the check mark to "verify your connection is secure" would just endlessly ask me to click the button and never continue. Sometimes it would say to unblock access to challenges.cloudflare.com.

But if I a launch an incognito window I can visit website with the challenge and it won't even ask! I've added all my extensions to run in incognito mode and everything still works, I can visit the websites in incognito just fine. So the one changing variable is incognito vs non-incognito.

I can have two windows open, one incognito and one not, and browse to the same website and the non-incog window will fail but the incog will just go to the site.

I thought incognito was supposed to only affect the session storage? Does it silently change other things to the running environment of the browser (about:config options, slightly different extension configs)?

Anyone know why this small change would suddenly allow cloudflare challenges to work?

I try to set up Firefox Sync on Firefox on a VM on Fedora. I enter my e-mail and password. Then I get the message (after retrying): "Email resent. Add accounts@firefox.com to your contacts to ensure a smooth delivery." However, I do not get the email with the confirmation code.

My email address has this format j@xxxxx.org

I stream video and after 10 minutes, graying out of screen or simply the steaming stopped. Repeatedly same problems. Problem for same streaming not seen using chrome.

I do online payment and screen locks up. I refreshed... no change. I paid in chrome... no issues Now notified that I may have paid twice. WTF?

Why suddenly problems with firefox.

HTTP/3 doesn't work regardless of my config:

network.http.http3.enable = true network.dns.httpssvc.http3_fast_fallback_timeout = 0 network.http.http3.priority = true

and https://cloudflare-quic.com/ and console still show I'm using HTTP/2. Tried on Firefox nightly and chromium (chromium works fine but firefox doesn't.)
