Firefox Support Forum

I have never managed to get Firefox Sync to work on my devices, I don't know why. I don't get an error message saying it failed or why it failed. I run Firefox on desktop (Linux) and Android, both always updated to the latest version.

My use case is simple, I just want my mobile Firefox to have all the bookmarks I have on desktop already.

On Android, when I go to my account settings it says "Las synced: never". Clicking the "Sync now" button does absolutely nothing.

On Desktop I go to Settings - Sync, press the Sync button. It appears to work, though no feedback is ever provided.

When I go to about:sync-log, on desktop, finally an error is shown. It seems to attempt to connect to https://sync-765-us-west-2.sync.services.mozilla.com/1.5/207352084/info/collections and fails. Manually going to the URL also fails on both desktop and mobile. Entire log below

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.

On a fresh install of openSUSE Tumbleweed 20240313 with KDE Plasma 6 (Wayland), the X button in the upper right corner of the screen does not allow you to click it when the pointer is in the upper right corner of the screen. Default behavior in KDE is to just let you close the window anyways even though the button itself is circular.

Is there any way to change this?

This issue has arisen on Firefox for Linux Mint (my current version is 123.0 (64bit)). I like Firefox, and I like its bookmarks toolbar, and have used it for many years, but there seems to be a new bug introduced today:- The bookmarks toolbar is present and correct when I start Firefox, but now it disappears as soon as I select any bookmark, or if I enter any web address or if I open a new tab. The [View >Toolbars > Bookmarks Toolbar > Alway Show] option is already selected, but the toolbar is no longer visible. If I click on it again, the bookmarks toolbar reappears (or I can restart Firefox, and this will also restore the toolbar). But the toolbar now disappears as soon as I use the browser in any way, and so is currently not really of practical use, as it needs constant restoring. Hope you can help resolve this. Many thanks in advance

Hi all, I've been having this issue for a while. I am unable to view streams on YouTube or Twitch (Twitch will show streams as offline, whereas YouTube will not even show streams), and I have encountered a new issue where YouTube allows only 360p on videos. I have used the HTML5 Video Capability Test and seem to have an issue in that department (images attached). Even in troubleshooting mode, the issue persists. Any help is appreciated.

I have a current version of Firefox (v123.0 running on Windows 10) but I can't do what I used to be able to do? (And it is making me nuts!)

I used to be able to resize the contents of a site - such as youtube or wordpress or tumblr - there would be a little % on the far right of the URL bar, and I could adjust that until the site was readable and all the pieces I wanted fit in. I can't find a control that will change this for me in the new version. Is it somewhere else? Did that control not port into the new version? Is is gone for good? (I really hope not!) I realize this is such a small problem, but it affects how I interact with basically every site online.

What makes this extra frustrating is that I'm not even certain I am using the correct terms for the thing I want -

Thank you for your patience -

I am having a very frustrating problem that is driving me huts.

Just the other day I was commenting in a text box like this one and I hit caps lock on my keyboard and a little grey box I had never seen before appeared with a locked lock. Then when I hit caps locks again on my keyboard an unlocked locked appeared in the little grey box. But it stays in cap locks and no matter what I do it won't go back to lower case. And when I say nothing shuts it off I mean its doing that on every site I try to comment on. Shutting down the browser does not help. And the only way I can get caps lock off is to actually shut down my whole computer and basically start all over.

You community volunteers are the best and quickest help I can get so I went straight to you for help.

I want to uninstall and maybe re-install some add-ons. But when I goto the add-on page. It just appears blank. So are some other pages in the support/ help sections. Another most notably, is (via menu) help -> more troubleshooting information. It just sends me to a blank page! See the uploaded images for the pages I get send to.

Help please with changing my add-ons

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 read all the suggestions but can't get Firefox Sync to transfer the open tabs from my old PC to my new one. I'm signed in on both to the same account, both are on my LAN with a wired ethernet connection, and I've checked every box in the "what to sync" field. When I click "Sync Now" the icon spins for a few seconds like it's doing something but the tabs from the old machine do not appear on the new one as I expected them to. Nor can I get them by closing and doing a Restore Session.

This seems pretty straightforward and how most users would expect it to work - am I missing something? If not, why isn't it working?

A couple of weeks ago I migrated from Edge to Firefox. I exported and imported my bookmarks. All was good. Suddenly this morning, my bookmarks are inoperative. The folder structure is there, containing entries that appear to be my bookmarks. If I left-click on one, nothing happens. If I right-click on one and choose Edit Bookmark, the fields in the dialogue are all empty.

Hi!

For a few weeks now I've had the problem that my Mozilla Firefox browser keeps crashing or hanging (the image goes black, needs to be updated or then crashes completely). This happens regardless of the website you open (e.g. google maps, mymaps, canva, instagram, google sheets, google drive, amazon, etc.).

Here are some of today's about:crashes IDs: bp-eee64bce-504e-4b09-bd26-d74a40240303 bp-aebd34b7-cdc1-49bd-9090-ca6b00240303 bp-b0970e4e-7f08-4672-9a4d-ca16f0240303 bp-14ded6d2-b81a-4d76-b79a-26b000240303 bp-d751619a-ce2f-4ffa-817d-0557c0240303 bp-27d145c4-4ef7-481d-9ffa-12e570240303

I already checked my RAM with memtest86. There were no errors. My tribers are updatet and I use Avast Antivirus & Cleanup Premium.

Do you have any idea, why this happens?

Kind regars, Minnie

Ubuntu 22.04.3 LTS Firefox 123.0 (64-bit)

The browser deletes cookies when closed. Every time I log in, I need to re-enter passwords (they are saved) on all sites, this is certainly tiring. I read about a similar problem from other users, they had the “Delete cookies and site data when Firefox is closed” setting enabled, but I didn’t.

In firefox 1230 I can't see which tab is active because it has been improved. is that such a great idea -I know it makes us fiddle around for longer and if that is the intention then no one will want to change it except me.

I recently noticed a number of places on websites where a cursor would appear in a place where no keyboard input is accepted. I've narrowed it down to this:

Define a div like this: <div tabIndex="1"></div>

Style it like so: div {

 width: 200px;
 height: 100px;
 border: solid 2px red;

} div:focus {

 background-color: lightblue;

}

Click inside the div. It turns blue to show it has focus, but it also shows a cursor at the top-left.

This does not seem to happen when you use <div tabIndex="1" /> and it also doesn't happen in other browsers.

In about:config I set browser.urlbar.clickSelectsAll to true and browser.urlbar.doubleClickSelectsAll to true

Now, single clicks in the address bar select the entire URL except when the address bar contains an address provided by New Tab Override. Does anyone have a fix for this issue?

Thanks.

Hi, I am using the newest Mac Air 15" with M3 chip, with the latest version of firefox (123.0.1) I have found an issue where when I put YouTube videos in fullscreen mode, the dock will not disappear like it normally would. The only workaround I've found is to put firefox in actual fullscreen mode (which then makes the dock disappear entirely), but I would prefer not to do as I typically maximize my screen instead. I'm assuming this is a bug on firefox specifically as fullscreen mode for videos/other things works normally in Chrome and Safari (which I also maximize screen), with the dock disappearing as it should.

I don't know if anyone else has encountered this issue though (as everything works fine on my older Mac...) Hopefully this can be resolved soon? I hope this makes sense :")
