Hi,

In the parameters, I chose to let Firefox ask me every time what to do with PDF files. But, when the window pop up and I click "Open with ... Firefox", the browser download and open with Firefox the PDF instead of only showing it in Firefox. When I set the "Open with firefox" by default in the parameters, Firefox will this time directly open the PDF in the browser instead of downloading it.

Are you aware of this bug ? Is there a solution ?

Thank you very much !

Whenever I use the searchbar in the bookmarks manager, it always searches all of my bookmarks, but sometimes I might only want to search for that query within a specific folder. Is there any way to limit a bookmarks search to only a specific folder rather than the entirety of my bookmarks?

Is there a way that I can express my trouble using gmail in Firefox, but have the gmail accounts work fine in Chrome and Edge? In Firefox, my gmail accounts show me as LOGGED OUT, when they are supposed to be logged in, and Firefox will not allow me to log into them again. I have 3 gmail accounts, [edited email from public] @gmail.com is my most active, but none will work in Firefox anymore, but in other browsers, they work fine. All other tabs I open in Firefox, works fine, so it's only my gmail accounts, that has trouble in Firefox. What can I do to correct this?

Thanks

Paul

So this issue just started and it's really annoying.

In order to actually see the downloads, I first have to enable the menu bar and then go Tools -> Downloads

Clicking the ↓ button should open a panel of recent downloads but nothing appears when I click on it. Furthermore, the "download complete" notification that this panel provides are no longer present.

The animation for the panel still works though.

Is there a solution to this?

I have fedora 36 Linux on my laptop and I have installed Firefox from the software store. The version in Help>About>About Firefox shows 99.0.1 (64-bit).

I am able to play videos on Youtube but no video or GIF is playing on Twitter/Reddit/Facebook.

I have installed media codecs as per this fedora help

My autoplay setting look like as per the attached image. I do not have any extensions except Bitwarden on Firefox.

I also tried playing videos on Firefox 100 by downloading it directly from firefox website but faced the same issue.

I have been unsuccessful in finding a solution in searches, so posting here. On one website I use, a machining forum, when I want to reply to a post, I have no text edit options ie bold, italic, emojis, etc. They are there, but grayed. They have worked previously for me. I don't know what changed like a setting on my part or an upgrade. I currently run Firefox version 99.01. I asked on the forum and other users have the same version and no problems. I can access the page with Chrome and on my phone (Android) and no problem so it is not my account. And on other forums, I ie different websites, I can use those functions. I have removed history cache and cookies, restarted Firefox and restarted the laptop.

Any suggestions?

For years I’ve had no difficulty accessing online my HSBC bank accounts in UK using Firefox. In recent days they have changed their security access method whereby their site now requests a security number generated on one’s phone using the HSBC App (it used to be a random number from an HSBC supplied handheld device) which then has to be input via my Windows 10 PC to access my data. If I use Microsoft Edge as browser, everything works fine, but when I try Firefox my system just hangs after I’ve put my bank ID into the HSBC opening page (the first security step) and simply never opens the next HSBC page which would ask me to generate the said code on my phone. Seems a browser related problem. Any ideas why Edge works but Firefox does not?

I don't know if this is a problem with my installation, but websites without specific favicons (e.g.: https://forum.librivox.org/index.php?sid=fd7dca1ba59c207dd25121695677d565) don't have a placeholder icon in the tab. Is this intended behavior? There's the globe icon for bookmarks without favicons, couldn't that be used if a website doesn't have one? I think that would contribute to some visual consistency :)

I have looked across various support forums for information on this, I only see posts regarding favicons and bookmarks, not the tab itself, so apologies if this has been asked and answered already!

When I open https://www.washingtonpost.com/ it loads but after a few seconds it goes blank. This started a few days ago and only happens on firefox.

Since the Firefox 99 update loading some pages (for example, the Gmail sign-in page) using Firefox on my Linux Mint machine, that I'm running a VNC remote desktop session on, results in a crash.

Crash report ID: bp-5dc1e89d-dc1f-40f2-9dbe-7f4380220419

I've tried running Firefox in safe-mode and the crash doesn't happen, but turning off hardware acceleration, swapping to default themes, removing all extensions, and completely removing Firefox and the .mozilla folder and then re-installing Firefox have not changed the crash behaviour in the absence of the safe-mode flag.

I would appreciate help in identifying what other paths of investigation I can take.

YouTube TV won't load in my Mac OR my Windows Firefox.

Error: "Please use the latest version of Firefox to watch YouTube TV on your desktop."

I'm running 99.0.1. Enhanced tracking off. Extensions off.

YouTube support has been no help! Any ideas here?

Thank you.

i recently lost my computer to destruction. i have a number of files saved by Mozilla backup on a thumbdrive. i have several backup files dating from 2014 all the way until now. after re-installing Firefox on a new computer, i tried MozBackup to restore my old Firefox from the latest file dated a coupla of months ago this year. the files have names like Firefox 16.0.2 (en-US) - 2013-01-05.pcv or .pfc. when i tryt and load it into backup it saysit isn't a valid backup file. how can i get this to work?

Hi I have been a user of Firefox for many a year, and this is the first tme I've come across an intrusive problem. Since updating to the latest version, I find I can no longer change the icon on a URL shortcut. I had quite a few of them, which helped distinguish (obviously) what I might want to select. That was then. Now, I have a load of indistinguishable Fireox logos which make finding the shortcut I want imossible. On going to change the icons, I find the Website Document tab in properties is no longer there .. while I have Firfox installed. Remove Firefox and the capability magically returns. I have re-installed Firefox in case of corruption, with no change. Before I remove Firefox permanently (which I'd be loathe to do), does anyone know the cause ... or solution or workaround?

FF updated yesterday with the new Ubuntu 22.04 (Pop) update to 99.01. Since the update the volume control inputs are essentially disabled on all web sites, and they default to max - even when muted.

Example - youtube - all videos play full volume Reddit - even muted videos play full volume

The volume can now only be controlled by the system slider.

The same behavior does not occur in other browsers - e.g. Chromium, Opera, etc.

Can anyone assist?

An error occurred during a connection to www.facebook.com. SSL_ERROR_DC_EXPIRED What in the world? does Facebook not keep up with its own security? or is this a Firefox thing?

I cannot play CNN videos in Firefox. They will not start. I can play them in Microsoft Edge and on my iPhone. I can play other videos in Firefox from, say, YouTube. It's just CNN that seems to be the problem. I have a Windows 10 PC.

When viewing email on Outlook in Firefox, there now appears a rectangular black box over part of every email. This does not occur when viewing Outlook emails on Chrome or Edge. I thought it might be because of my adblocker (Ublock Origin) so I turned it off, but the black rectangle still covers part of my messages (and I have Ublock on Chrome, too, with no problem viewing Outlook).

The rectangle covers only a portion of the messages. When I scroll the message, the black rectangle remains stationary and the message scrolls behind it, thus revealing the portion previously covered by the black rectangle (a different portion of the message becomes covered).

I tried to take a screenshot to show the black rectangle covering part of the message. Amazingly, even though the black rectangle is there when I take the screenshot, the screenshot itself does not display the black rectangle....instead the message appears in the screenshot without being partially covered by the black rectangle.

I am trying to transfer my bookmarks, open tabs and passwords etc. from my old laptop to my new one. It appears I have to do this with Firefox Sync under the preferences menu. However when I try to connect a new device, I am told to open the code scanner on my Firefox App, which sounds like I have to use a mobile? How do I scan the QR code using my new laptop?
