Diễn đàn hỗ trợ Firefox

As of today, I am unable to scroll with my mouse in google sheets. The scroll bar on the right disappears and I'm taken to the bottom of the spreadsheet and can't scroll back up. I have to use CTRL+Home and then the arrow keys to go down the rows. This appears to be only on Firefox. I tried a different browser and it worked fine.

As I understand, `autoconfig.js` (with `firefox.cfg`) can be used to have JavaScript run during startup to control Firefox's UI elements.

I have set up `autoconfig.js` in my `/usr/lib/firefox-developer-edition/defaults/pref` folder (I'm on EndeavourOS Linux). As instructed here, I've already put the two required files, `autoconfig.js` and `firefox.cfg` in their correct folders (`/usr/lib/firefox-developer-edition/defaults/pref` and `/usr/lib/firefox-developer-edition` in my machine).

The file `firefox.cfg` contains the following code:

 //
 (() => {
   var tabbar = document.getElementById("TabsToolbar");
 })();

However, every time I run Firefox, this message will appear:

 "Failed to read the configuration file. Please contact your system administrator."

If I empty out the `firefox.cfg` file, Firefox will run normally without showing the error message. It will also run normally if I just have something like this in the file:

 //
 (() => {
   var testVar = "";
 })();

I don't understand why the JavaScript code can't access the Firefox UI elements through `document` or `window.document`. If `autoconfig.js` isn't build for that, what should I use to change my browser's UI elements through JavaScript?

Thank you.

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 using Firefox 123.0.0 (rel. 20-Feb-2023) on a Win 10 Pro v22H2 computer.

I understand that FF123.0.0 is supposed to include a new option to "Report Broken Site" on the menu (hamburger icon) that is described in the support article How do I report a broken site in Firefox desktop? but I can't see this new option. I also checked the menu options under More Tools and Help but can't find it.

Exiting and re-opening Firefox didn't solve the problem.

I have been experiencing a problem with Cloudflare specifically on one site (character.ai) and when the verify you are human pops up. It takes me in a seemingly infinite loop. On the Cloudflare community site they say it could be because of things like adblock but even without any adblock or anything of the sort on it does the same thing. Sadly Cloudflare community doesn't support being used on Firefox. So maybe they don't support being used on Firefox in general? I have contacted the actual websites support but they don't seem to even read submitted inquiries because I never hear anything back from them except the automated message they received it. It is now preventing me from using certain things in general which as before it wasn't that big of a deal but recently they changed the site layout and still allowed you to use the old layout but the verification blocks you from using the old layout. The first one is one from a couple of weeks ago when it only effected me trying to open things in a separate tab and the second one is the newer one which prevents me from accessing the old layout. I'm not sure what to do about it since nothing I specifically could do to solve it has helped. I have opted into sharing data under troubleshooting IDK how well that'll help.

Hi,

For as long as I can remember I've been able to ctrl + click in the "text area" beneath the link in DuckDuckGo search results and Firefox would open a new tab and switch to that tab automatically; but if clicking on the link itself Firefox would open the link in a new tab in the background. This was a priceless feature until today with the 123.0 update. Now ctrl + left click in the text area opens a new tab in the background but does not switch to it. I've been able to confirm this is only effecting v123 on all both linux and windows.

Hoping somebody here might be able to suggest to development returning this feature back to Firefox or help me figure out a way to set this option manually myself.

Thanks!

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

I just recently had Firefox updated, and I'm already having problems regarding notifications. When a notification starts up while I'm typing, it takes me out of it and I have to click back in. I had to turn them off temporarily to avoid flow breaking. This never ever happened before the update as the notifs worked perfectly fine w/ no interrupting. I also noticed in the taskbar, each notification is treated like a new browser window for some reason. This may be related to my current issue.

Hello,

I use Firefox stable on both my Mac and my Win 11 PC. On the mac i use the developer edition. The issue I have started about 2-3 weeks ago. Most of the time, playing youtube 4k videos just either freezes and doesn't buffer, or just skips and reloads. It is not a network issue. I've tried playing back the same video with ARC on OSX (which is based on chromium) and with Chome on windows. It works flawlessly so it's not a network issue. I've tried disabling adblocker, all the extensions, nothing. It's either Youtube messing with non google products again or a problem with Firefox itself. I even have Youtube premium and this stuff still happens without adblockers.

Any help would be appreciated.

Recently I had to refresh Windows 11 on my Dell desktop. It defaulted to McAfee antivirus. I uninstalled McAfee and reinstalled Norton 360 which I had before. I reinstalled Firefox. I have version 123.0.1. I imported my FF bookmarks after exporting them from another computer. Now, FF remembers my IDs but not my passwords. When I log in to a website, FF offers to save my password and when I click yes it pops up a bubble saying "Password saved!" However, next time I go to that website, although it remembers my ID, it does not recall my (supposedly saved) password. In this support site, I see most users with this problem say FF will not remember either their IDs or passwords, whereas FF remembers my IDs, so my problem may be different. In FF help, I see that another password manager could be keeping FF from saving passwords. To the best of my knowledge I have never used another password manager. What is keeping FF from saving my passwords, while remembering my IDs? Is there a Windows Registry setting or a FF About:Configuration setting I need to change? Is re-installing FF a last ditch option?

Hello, I use Firefox as my only browser and I use the shortcuts because they're really helpful. But every time that I lunch Firefox all the pages in the shortcuts "call" their websites, I see it from pihole and all the requests are made every first lunch of Firefox. Probably it's something related to the cache and to give better perfomances in case I wanna select one of those shortcuts, but I don't want that all of them make a "call" to their respective websites. I think it's something related to privacy and freedom about what I want to do with mt browser. Is there an option to block those connections? In case there isn't an option is possible to implement it? Thank you so much

Hi all, In the past I was using Chrome and I have decided to move back to Firefox because I didn't like certain trends of that browser...now...the thing is...I like to use Yandex, but in Chrome -until a certain point- I was able to alter its settings to force default English language for it.

Firefox seems to have Yandex set as default...you cannot alter it and you cannot delete any of the default engines (i.e., because if it is loaded, you seem unable to try add it as custom search engine with your chosen parameters), but seems that the Mozilla developers had the brilliant idea to add it with the default settings...which is in Russian...

...and you look into Extensions and all the people writing extensions seemed to have the same idea...

Now...fine that Yandex is mostly for Russian people, but why English-speaking users to be forced with the default search in Russian and being completely denied any possibility to force the English language on Yandex (as it is fully possible if you were able to tweak the search parameters...but Firefox isn't allowing to do, because the only thing we have is a dumbed down interface with a list of search engines!)...

...alternatively...why not allow to force our favored language parameters to ALL search engines by default?

( That would mean that one could have Google, Bing or Yandex in a different language of our choice....but that change would need to be implemented on developer side...)

Update 123.0 deleted all my firefox data from logins.json. backup files are corrupted or have no data. No support article suggestions have worked. The .json files indicate that there is data, but appears blank in notepad, and wont load in json reader in firefox

I do not use SVG

AFTER RESETTING MY MACBOOK PRO I DISCOVERED THAT MY ALL MY PASSWORDS AND EMAIL SAVED TO MY ACCOUNT HAVE BEEN REMOVED/DELETED. PLEASE HELP WITH THIS PROBLEM AS SOON AS POSSIBLE. THANK YOU.

Hi, I watch specific streaming live show on YouTube every week. Unfortunately, I always have to play it in non-Firefox browser, because the video freezes every couple minutes, while audio track is still playing in the background. Based on the comments from the stream chat, other people have this issue too. Why? How to fix it? It is annoying. Internet connection is ok. Other browsers no issue. OS Linux Mint 20 Ulyana 64-bit Kernel Linux 5.4.0-172-generic x86_64 MATE 1.24.0 Mozilla Firefox 123.0 (64-bit)

For the past week, when I sign into Facebook, the news feed is constantly refreshing itself. Once in a while the first post will stay, but the remainder of the news feed keeps refreshing. It is impossible to read anything as posts flash on and off, mostly off. The news feed is the only thing that is affected, visiting pages for likes and groups load and display properly, as do the games I play. The same occurs if in the private window mode. This does not happen if in the Chrome browser. What can be done to correct this situation?

Hi,

I'm trying to remove the bar at the top of firefox browser with tabs in them. I read another article (https://support.mozilla.org/es/questions/1417387#answer-1588947) under spain link, i think, and the solution said to write "TabsToolbar-customization-target { visibility: collapse !important; }" somewhere. Where do I go to write that?

I tried the console by pressing f12, but that doesn't seem like that's it. In that article it also mentions to go to about:config and change the status of "browser.tabs.drawInTitlebar" to false, or delete it, but didn't work either.

Whenever I log on to my bank's web site, I'm sent an audible signal that invites me to start a chat session with a bank agent. The problem is that the audible alert is so loud that it startles me. This is very annoying. I called the bank's help line and was told there was no way they could adjust the sound volume. I would like to know if it's possible for Firefox to decrease the volume for that web site.
