Firefox Community Forum

Firefox has an excellent built-in screenshot feature that allows users to take full page screenshots of web pages. I am a Mac user. I use Sugarsync cloud service to keep my Mac Studio desktop (OS 12.6.3 Monterey) and Macbook Air (OS 13.3 Ventura) laptop in sync. I am running Firefox 133.0.

I have noticed that Firefox .png screenshots have not been uploading properly to Sugarsync for the last 6 months or so. In Finder a green tick appears which indicates that a file has been properly uploaded to SugarSync but when I go to the Sugarsync app I can see the following error message for such files "Waiting on upload from Mac Studio". This means that screenshots I take on my desktop do not go across to my laptop and vice versa.

I spoke to the very helpful tech support (Luis M, senior tech support) at Sugarsync today and he and his colleague were able to figure out that the problem has to do with the attributes of the saved .png files.

I will outline the issue in detail:

On a Mac you can examine the attributes of a file by doing the following: - right click on the folder in which your file is located and click "new terminal at folder". This opens a new terminal window - type the following: xattr -l and then drag and drop the file name from finder next to the "xattr -l" and then insert a space, a dot and a forward slash and press enter, i.e. myusername@NameOfMyComputer Foldername % xattr -l full path and file name ./

For example if I take a screenshot of the following URL: https://www.mlb.com/ and I save the screenshot in a folder I have named "Firefox Screenshots" it saves as as "Screenshot 2024-12-07 at 14-48-02 MLB.com The Official Site of Major League Baseball" on my computer. I can examine it's attributes in terminal using the steps outlined above:

myusername@NameOfMyComputer Firefox Screenshots % xattr -l /Users/myusername/Firefox\ Screenshots/Screenshot\ 2024-12-07\ at\ 14-46-28\ The\ New\ York\ Times\ -\ Breaking\ News\ US\ News\ World\ News\ and\ Videos.png ./

When I click enter it generates a massive amount of information that looks like this: /Users/myusername/Firefox Screenshots/Screenshot 2024-12-07 at 14-46-28 The New York Times - Breaking News US News World News and Videos.png: com.apple.metadata:kMDItemWhereFroms: bplist00?_ /Users/myusername/Firefox Screenshots/Screenshot 2024-12-07 at 14-46-28 The New York Times - Breaking News US News World News and Videos.png: com.apple.quarantine: 0081;6753c517;Firefox;0F67116D-C970-45CB-A578-65EAFC93F6DD myusername@NameOfMyComputer Firefox Screenshots % xattr -l /Users/myusername/Firefox\ Screenshots/Screenshot\ 2024-12-07\ at\ 14-48-02\ MLB.com\ The\ Official\ Site\ of\ Major\ League\ Baseball.png ./ /Users/myusername/Firefox Screenshots/Screenshot 2024-12-07 at 14-48-02 MLB.com The Official Site of Major League Baseball.png: com.apple.metadata:kMDItemWhereFroms: bplist00?_Q?^data:image/png;base64,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 etc etc etc

The total output is over 19 million characters long due to the long alphabet soup that is generated. And this why Sugarsync is unable to properly upload the file.

You can retrospectively fix folders that contain .png files that will not properly upload to Sugarsync by right clicking on a folder, selecting "new terminal at folder" and typing the following: xattr -d -r com.apple.metadata:kMDItemWhereFroms ./

This fixes the attributes and the .png screenshots files immediately start to upload to Sugarsync. When you examine the attributes of the file again it shows the following:

/Users/myusername/Firefox Screenshots/Screenshot 2024-12-07 at 14-48-02 MLB.com The Official Site of Major League Baseball.png: com.apple.quarantine: 0081;6753c575;Firefox;D5072DFA-9EE8-4EF1-9658-86263462F1CD.

Could the Firefox developers please look at this issue and liaise with Sugarsync?

Many thanks in advance.

We apparently lost power sometime during the night. When I turned on the monitor and opened FF, I got the error message that it had crashed. As my subject line says, I lost all my tabs, the pinned ones (probably about 10) as well as the open ones (probably between 10 and 15). I also lost all my history. I can't use the 'Restore Previous Session' because it doesn't give me that option.

I've restarted Firefox and also rebooted my computer...still nothing happens. It's up to date, version 133.0. But I have no history beyond this morning. Is there any way I can recover those tabs or history?

And in my FF Settings, there's a link at the top that says "Your browser is being managed by your organization". I don't have or belong to an organization. When I click on the link it takes me to another page that says it's "Active" and there's a huge list of "Documentation" that apparently involves a lot of code. Can you please explain what all that means? Thanks so much for any help!

After updating to v 133.0, when maximizing Firefox (not F11 fullscreen), a taskbar that is set to "auto-hide" will no longer unhide when mousing to the bottom of the screen. This did not occur with the previous version (132.0.2).

This behavior is also unaffected by the "devtools.toolbox.alwaysOnTop" setting in about:config as i've tried switching from the default "true" to "false".

Update: Still persists in 136.0.2

I've been having an issue with picture-in-picture (PiP) mode where the subtitles and rewind/fast-forward buttons (rr/ff) won't follow the video into the small player for Disney+ specifically. I have no issues with YouTube or any other site. The subtitles and rr/ff just stay with the original video player on the site while the video is in PiP mode. I can see the subtitle button on the PiP player, but it is grayed out and I can't click it. I've updated both Firefox and my computer (Windows 11) and reinstalled Firefox, cleared cookies and cache, and still no dice. Any advice? Thanks!

(In the screenshot, the PiP player isn't showing video, but I think that's just because of Disney's anti-piracy software - I can see the video in the PiP player on my screen.)

Hi I have windows 11 pro 24h2 I cannot connect to the firefox Desktop bworser on my desktop computer It gives me this message Please!! Any help would bwe great

I accidentally activated 'block element' for my homepage 'www.msn.com'. Now the site comes up blank. How do I reverse the 'block element?

The website WSJ has large areas on front page, including the opinion listing, are simply white and not 'there' on the page to click on. I've deleted their cookies without effect, tried turning off all adblockers, shut mac down to reboot, nothing seems to have an effect. This is a recent glitch of only several days, prior performance was great. Thanks!

Hi, my session with a lot of open tabs has been lost due to a crash. In the profile folder, the recovery and previous files in the sessionstore-backups have been deleted. I tried to recover them using shadow explorer, but these files are corrupted, so I've had no success reading them. Is there a way to fix the corrupted files? Alternatively, because I've had sync enabled for open tabs, is there a log for past open tab synchronizations? If this was stored on the cloud, it may be possible to retrieve that table and restore the list of open tabs that way?

I can no longer access my local TrueNAS server nor router via Firefox. My current version is 133.0.3. Safari has no trouble. Firefox gives no warning, no Advanced button, no option to bypass security. All I get is: "Unable to connect An error occurred during a connection to 192.168.0.102.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web."

I have tried so many settings, troubleshootings, workarounds, I can't begin to list them. It happens in troubleshooting mode. I have created SSL certificates on the server many different ways to no avail. I'm thinking I will have to abandon Firefox with it's obscure, no-way-through security. But I wanted to ask for help first. Please help.

Paypal hangs when transferred from vendor site to complete purchase. Relaunching Firefox in troubleshooting mode resolves issue. Also works with Safari. What's wrong, what needs to be changed?

Does anybody know which options to use on the command-line start of Firefox such that the only thing displayed is the area within which an HTML page would be presented?

I want to have it start with everything else turned off or hidden, namely

   memu bar
   page tabs bar
   address bar along all add-on buttons
   bookmarks sidebar

The "-kiosk" option is not appropriate for my needs.

-kiosk doesn't hide the sidebar (Bookmarks or not) if that sidebar was visible during last session before exit ... so ... no, "-kiosk" is not a proper implementation of a "page-only" display mode.

"-private-window" gives no benefit, display-wise, over and above what the "-new-window" option provides.

Everything I've read (even on the Mozilla support site) seems to point to creating a special profile for just that mode, and then to modify the "userChrome.css" file with custom properties to ensure the desired "off" setting for the GUI elements. That seems a rather "small-minded" view, ignoring the potential for huge market of self-contained hard-coded applications that would need only use the Firefox rendering engine, and nothing else!

One comment on Reddit indicated that the functionality was there ("-app" option working with XULrunner), but discontinued!

As a test, I did close all my browsers, leaving the bookmark sidebar visible before closing. I then entered:

firefox -kiosk -safe-mode -private-window ${URL}

I still get the bookmark-sidebar visible, with everything else "hidden" or "disabled", because visible sidebar is my default mode for normal browsing.

Is there no command-line startup switch to force that sidebar to "hide", equivalent to clicking on the "X" on the top-right corner?

OR ...

Is there any programmatic way to tell that to hide using JavaScript in the HTML page that is loaded? Everything I seem to locate refer to in-page Elements only, not Browser Elements. :frowning:

But "kiosk"(fullscreen-mode) is not the mode I want, because I want users to be able to have the simplified browser-based HTML App co-exist on the desktop with other windows, like a normal App.

I've tried using this alternative content for the JavaScript file, but that also failed (using '*hideSidebarBookmarks()*' call in the in-line script segment):

``` function hideSidebarBookmarks() { const sidebar = document.getElementById("CustomizableUI.AREA_BOOKMARKS") ; sidebar.hide() ; } ```

I even tried replacing the word "document" with "browser" in the above, still with no success. :-(

The above will display per the attached image.

My GPU is the integrated GPU on the Intel U7-155H CPU. When some AVC videos are played, the browser reacts extremely slow and the video image is glitched and at a really low rate of frame, and the video decoding engine seemed to be 100% occupied as shown in the task manager (normal video playback never occupied so much of it). Seems like AV1 encoded video never triggered the problem. The problem doesn't always happen, but at a rather high frequency. This never happened before I updated the Intel graphics driver from 32.0.101.5972 to 32.0.101.6129. The problem seemed not to happen on other browsers such as Microsoft Edge.

Hello, earlier in the day I pressed a keyboard shortcut on accident when picking up my keyboard and has changed google results quite dramatically. I grabbed my keyboard and had a menu pop up on the left side and after i closed it noticed my google results had a scroll bar now. The results page only presents itself on the left half of the screen and a scroll bar has appeared on both the right side, cutting off text, and bottom of the page. These scroll bars only move a tiny bit and are quite unnecessary, but makes scrolling a pain as I have to be sure I am outside the new scroll bar area as they take precedent from the main scroll bar. I have googled Firefox's keyboard shortcuts and haven't found the one i need to fix this. Before I'm asked, no I do not have crazy zoom on and no zooming in does not fix this problem.

For the last several weeks, Firefox has been prompting me to "Please enter primary password" multiple times per day or even per hour. If I do so, the dialog box goes away, only to come back again later. I'm finding this very frustrating.

Firefox does always prompt for this when I start it, as it has for many years.

I tried the recommended solution for a similar problem presented here but it didn't help.

This started some time after I updated from 130.0.1 to 133.0, but I have no idea whether the update is the cause.

Can anyone recommend what I can do to solve this or at least to investigate it further?

My computer died about three days ago, and firefox had three windows open. When I rebooted the computer again, firefox automatically started up, and the flyout panel thing that shows up when you right click on an app claimed that all three windows returned. However, only two of them were actually accessible, and clicking on the app to move between them and the F3 window confirmed this. Clicking on the third window accomplishes nothing, reveals nothing, and just moves the little checkmark around in that flyout panel. Closing the other two windows before restarting firefox does not open a new window because it thinks one is already there, but I cannot in any way see or access it outside of its label in the flyout panel. Even hitting "Show All Windows" just shows the window I am typing this in. What am I supposed to do here?

When my Firefox crashed today, I chose to restore it rather than troubleshoot. When it was done, my bookmarks icon had disappeared. Yet when I go to the individual websites, I can see that each one is still bookmarked. How can I restore the icon that used to be in the toolbar at top? Thank you for any help you can give. I have been using Firefox for many years now and this is the first time I encountered this problem.
