I'm not very good at English, so I use a translator. After updating to the latest version of Firefox, the problem I'm having is that when I play a YouTube video on the web side, the playback box will have a large white colour, as shown in the red box below. I would like to know what is causing this, my current version is 123.0

Whenever i put javascript code into the url box when making a bookmark, (trying to add a bookmarklet to my bookmark bar.) after i click save, the bookmark just doesnt even show up, its like firefox isnt even making the bookmark. i dont even know whats going on it was doing this before i had any addons

Firefox keeps offering to translate websites, your new feature.

I neither want it to, nor do I appreciate ads, because it is simply you advertising your new product.

I have looked at the settings and there are 0 languages for which I've set it so it will offer me to translate and 0 for which it will do. Besides the fact I do speak and read multiple languages; it is not a feature I am interested in.

So when I set it so it will not bug me about it and every time I enter a foreign language site the little pop-up shows; that's some serious unwanted ads and also clearly FAR more tracking than FF is even supposed to be doing.

I have used firefox for nearly 15 years, but I'm honestly wondering if I should find another privacy focused browser One that doesn't spam me with little pop-ups over it's latest ill-conceived stupid feature.

So you could help by actually NEVER-EVER under any fucking circumstances show this stupid translation pop-up UNLESS I put I request it to do so in the settings or at the very LEAST allow me to turn it off.

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.

I've just tried to save something from firefox on linux(Manjaro KDE) and was baffled that there doesn't seem to be a way to manually enter the path and navigate to it in the save dialog. In addition to that, there are many locations missing and I can't seem to find a way to add new custom or favorites ones either.

All that combined means it was impossible to save my file directly to a network location, which is something I very often need to do. It just seems insane for such a basic feature to be missing and I've found a 4 years old thread about it meaning nothing has been done to fix this since? https://support.mozilla.org/en-US/questions/1279125

The only way I can see would be to mount the network path(not a good solution for one offs) and navigate to it(a symlink can make it closer to one of the existing shortcut but still annoyingly require more clicks) every time but that's very tedious since most of my saving is on a specific server drive.

Yesterday, I ran a format on my computer with Firefox in installed on it. When I tried to recover my settings, history and bookmarks later using sync after logging in to my account nothing happened. Can you please help me recover my data? Thanks in advance.

How can I restore a previous theme? I had a "colorfore" theme that Mozilla offered a few years ago set up in Firefox. It was perfect! I could see everything clearly with my aging eyesight.Then one of my synced computers needed a new Linux OS installation so I signed out of sync on that machine. Installed the new OS. When I started Firefox the first time I signed into sync. I got my history, bookmarks and bookmark bar, but no custom colors. Now my computer at work has its colors reset to the out of box colors too. I have lost the colorfore colors I have been using for several years now. How can I get the colorfore colors back? Thank you for your attention in this matter. I love Firefox, use it exclusively and contribute to Mozilla. Gregg Scholfield

When launching Firefox Malwarebytes reports a trojan and shows blocked website verifications.io This happens just about every time. Wikipedia tells me "Verifications.io is a defunct email-focused technology firm whose primary practice was to validate email addresses for email marketing platforms. The company's platform allowed for email marketing firms to submit lists to the company, which would verify the lists for valid email addresses."

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

Maybe my cat walked over a certain key and disabled something or the new version of firefox won't let me cycle through previous typed chat messages anymore. while streaming on twitch i have to repeat certain chat messages which i did by typing the up and down arrows. lately it doesn't work in firefox anymore (OBS has a chat box which still has this function tho) is there an option to disable/enable cycling through previously typed text and which key does that?

YouTube all of a sudden started to slow down and only be able to load videos fast enough in 360p resolution, I tried watching YouTube on Microsoft edge and YouTube handled 1080p easily there, I have cleared the cash and made sure my Firefox and Windows are up to date and still the issue persists.

this only seams to occur on YouTube as amazon prime and speed test works without issues

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.

Sometimes when I go to click on songs on YouTube it doesn't show the whole bottom part of the video's screen. It has some of it but does not show the fullscreen mode option to click on. When i open up Chrome it's fine. I'm using the newest update of Firefox.

When I try to screenshot (Windows+Shift+S) and paste the screenshot into Google Translate, I get the error message:

Unable to paste from clipboard right now. Try copying the image again.

This functionality works in every other browser I've tried (Chrome, Edge, Brave, Opera GX), so it's not a Google problem, I don't think.

Hello folks

According to Firefox help pages, pinning an extension to the toolbar should work as follows:

"Click the extensions button (jigsaw puzzle Fx109ExtensionsButton icon) in the toolbar to open the extensions panel. Each extension in the panel has a menu button with a gear Fx91GearIcon icon. You can use this menu button to manage those extensions."

The extensions button doesn't seem to work like that for me. When I click the Extensions button I get several buttons (Recommendations, Extensions etc) on the left side of the page as in the first image attached (Firefox1).

If I then click the Extensions button I get to the Manage Extensions page, and if I then click the 3 dots (...) button on (say) Proton Pass I don't get a Pin to Toolbar option and clicking the Manage option opens the Proton Pass Details page (see image Firefox2) - none of the buttons on the any of the pages offers a Pin to Toolbar option.

Those extensions that are pinned to the toolbar, such as Adblock Plus ( see Firefox2 image), got pinned during installation and not by using the extensions button. Currently I seem to have no way of interacting with any extension via the extensions button.

Could be I'm doing something silly but any suggestions would be appreciated.

Regards Ken

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

Twitter's login page won't load when I try to open it in Firefox. https://twitter.com/ https://twitter.com/ loads just fine, account pages like https://twitter.com/firefox load just fine, and individual tweets individual tweets load just fine. But when I click the login button on any working page, or go directly to the login page at https://twitter.com/i/flow/login, all I get is a white rectangle in the middle of the screen that flashes a loading-spinner for a few frames every two seconds but never actually loads any page content.

I can log in just fine in Chrome, so the problem is specific to Firefox. The problem started at least a week ago, but I don't log in on my desktop regularly enough to know exactly when the problem started.

I turned my Browser Privacy setting to "Standard" and cleared all site data from Twitter, with no effect. I use uBlock Origin, but the problem persists when I disable it. The problem also occurs in Private windows.
