Opening PDFs automatically with Firefox and, without any changes I might make, saving them with the download function in Firefox, actually ruins the functionality and data entry function of that file. Specifically this happens with PDF files downloaded from the (not all that amusing) PDFs from the FINCEN, (US Financial Crimes Enforcement Network). I do not see why and how Firefox thinks it is allowed to change files that are simply downloaded and saved on Firefox.

In other words, it seems that Firefox strips away certain "permissions" and/or "functions" (like built-in lookup, menu or choice boxes). This means that the file so downloaded via Firefox can no longer be used to properly fill in data, or to look up and choose data items within the file. (I see many times that ANYTHING having to do with "permissions" tends to be an intractable and unsolvable problem for software makers & experts, so, if you do not know right away how to solve the problem, it will probably take you several years to figure this out.)

The PDF in question is created by a government agency. If you have ever dealt with a government agency, then you know that they act sort of like Adobe or Microsoft: "They don't respond, or they do respond & say they do not understand, and if they understand, they are either unwilling or unable to fix the problem."

If there is a switch or option within Firefox, which lets me tell Firefox "Save this file exactly like it is received, nothing added or removed!", that would be nice. I just have not found such an option yet, and it would be nice if it might get provided someday.

I will share my browser data, but I am sort of convinced that a detailed question like mine will not be addressed within that shared data.

When I want to to send a link through whatsapp, Firefox defaults to the web page (uninstalled) instead of the desktop application (installed) and I have to open it manually. It started a while ago and is very annoying.

Hi I very often have problems playing videos on X/Twitter but not all of the time. Some videos just won't play but others do no problem. It's very frequent though and i have searched for a solution to this and can't find one.

Hello, I noticed a few times that after waking my computer up from sleep mode, I seem to lose audio from the browser completely. I look into my audio mixer and I do see the browser is giving audio, but I can't hear it through my headphones.

Last time i fixed it, I had to restart my computer and it fixed the issue, but I don't want to continue in having this issue at times. I have also tried restarting firefox by ending it in the task manager and re-opening it, but that doesn't seem to fix it.

I recently started to have a printing problem in Firefox on Windows 11. My Brother DCP-T720DW works fine with other applications like Word and Notepad, but when I try to print from Firefox, sometimes I get a "Printer not available" message or the print dialog incorrectly shows the printer. For troubleshooting, I uninstalled and then reinstalled the printer driver following the official Brother download page: https://support.brother.com/g/b/downloadtop.aspx?c=us_ot&lang=en&prod=dcpt720dw_all Since that didn't fix the issue, I also downloaded and reinstalled the driver from: https://printerdrivers.com/brother-dcp-t720dw-driver/ Windows detects the printer and is able to print test pages, so it looks like the problem is only with Firefox. Here are the things I have tried: Restarting both Firefox and Windows Uninstalling and reinstalling the printer Resetting Firefox settings Running Firefox in Troubleshoot Mode Making Brother printer the default one

Has anyone else had the same issue in which Firefox refuses to detect a printer that works correctly in other applications? Is there a print setting or preference in Firefox that might cause this? Thanks in advance for any advice.

I keep having trouble with Facebook. The site keeps reacting too slowly, and just hangs up. I have to wait too long for the the content to fully load. I tried clearing my cache as suggested and that didn't help any. What can I now do to solve this problem. The Facebook problem is NOT present when I use another browser, like Chrome or Safari, only Firefox so the problem is Firefox related. Can someone please help. Thank you.

(Note: this issue is probably the same issue as reported in 1439701 - Mouseover link tooltip url persistent through click and page load. While that user marked that issue as solved, their "resolution" makes fairly clear that the issue was never really solved.)

When hovering over a link, Firefox will typically show a tooltip at the bottom left with the link's address. Typically, this tooltip disappears when the mouse is no longer hovering over the link (whether because you moved the mouse or clicked the link). However, in some circumstances, the tooltip doesn't disappear when it should. Here's an example of how to reproduce the issue:

1. Go to YouTube 2. Search for anything. 3. Choose a result, and click on the thumbnail. (NOT on the title.)

Expected result: the tooltip showing the URL of the video disappears since the video is loading and the link you clicked no longer exists on the page.

Actual result: the tooltip persists. Once you hover over any other link on the page, behavior will return to normal.

I recently purchased a new desktop due to the previous desktop malfunctioning a bit. The old hdd is still in operating condition and is now a slave in my new cpu. Where can I find the history/bookmarks on the old drive? Is there a filename that is relevant for the data?

Thanks

Hi Mozilla team,

After a recent Firefox update, my Home/New Tab page changed dramatically and became hard to use. The issue is not just that the layout looks different — the new page is functionally worse for me because the shortcuts are oversized, they obscure the search bar area, and the trending/recommended stories are difficult to read.

I tried the usual fixes:

   I changed the New Tab/Home settings.

   I tried the about:config change to restore the older layout.

   The page returned to normal once, but only for one instance; after that, it went back to the problematic layout again.

So I think there are two problems:

   The redesigned Home/New Tab layout is too cluttered and interferes with basic use.

   My preference change is not sticking, because the page resets after a restart or later reopening.

What I need help with is:

   Why the Home/New Tab page is reverting after I change it.

   Whether this is caused by a Firefox study/experiment, session restore, a profile issue, or an extension.

   How to make the older compact layout stay permanently.

   My Firefox version is 153.0 (aarch 64).

   The problem happens after every restart of Firefox.

  Troubleshoot Mode changed nothing.

   The browser.newtabpage.activity-stream.nova.enabled setting was reset to false and that has held.

   I'm on macOS

   Using Sync across devices.

In addition I cannot find session restore - I was going to try unchecking it to see if that helps

I have an insta 360 webcam with Virtual Camera enabled. Is there a setting for Firefox where I can select from a list of available webcams (cameras)? I am suspecting it is trying to use either the integrated laptop camera or the Insta360 without using the Virtual software.

Thanks in advance for your help

The "Post" button is off screen on the share popup when I try to share a post in a Facebook group to another group. The problem has been getting worse. Usually I can see a slim piece of the top of the button, but today it disappeared completely. The only way to make it visible is to press Ctrl -. Then select Zoom > Actual size from the menu when I'm finished.

Why doesn´t the new checklist widget (that apperas on a new tab) sync between my different computers?? As it is now, it is totaly useless. If i create a checklist on my homecomputer (logged in with my firefox account) it does not show up on my work computer (also logged in with my firefix account). Eveveything else is syncing fine, but not the widgets...

Hello, I am hoping someone can help me. I am getting white pixels/lines during youtube play back. There is only ever one at a time. I do not get it every time I watch a video. The lines move with the player if I move the browser.

I have tried: Updating Firefox/drivers Turning Hardware acceleration on/off Setting Firefox to use the dGPU Changing the Optimus mode

I am using Windows 11 and have a Legion 7i Pro Gen 8

I have uploaded an image that shows the line. The line appears in the grass on the right.

Many thanks

Whenever I click any link that will play a video in a video playing website such as YouTube, Instagram or TikTok, it will cause the entire tab to glitch out and freeze in on the page it was on before I clicked the link.. The entire tab completely freezes and never unfreezes itself, with the cursor having whatever appearance it had when the page froze, and being unable to click anything. The only thing it can do is type a new URL into the search bar, but the search button/enter bar is also ineffective, so I'm stuck on a frozen webpage unless I close the tab or change to another one. I've tried troubleshooting, fiddling with the autoplay setting and turning off extensions, none of which worked. Any ideas?

How can I make sure the Vertical Tabs sidebar stays visible in full screen mode?

It worked this way by default until the [154.0 release](https://www.firefox.com/en-US/firefox/154.0/releasenotes/#note-792047):

> Fixed the Vertical Tabs sidebar staying visible in full screen mode. It now hides along with the toolbars and reappears when the cursor moves to the edge of the screen.

Is there a config setting that re-enables the old behavior? I want the address bar to be hidden in full screen mode, but not the Vertical Tabs sidebar.

When I watch Downton Abbey on PBS from outside the U.S, using the Firefox VPN in a Private Window the Closed Captions of the PBS video are displayed TWICE: one above the timeline and the other above it.

This issue is specific to this particular show AND to the Firefox browser.
