When I download PDFs on my MacBook using Firefox (currently 124.0.2 (64-bit)), they are always blank - I have attached a screen shot.

But if I download the same PDF using Safari, it opens straightaway - 2nd screen shot.

Is there something I need to adjust in Firefox to allow PDFs to open?

Hello! I've recently switched to Firefox from Opera. However: After the browser Closes, It will always Refuse to boot up. Even Shift-Click Doesn't work. It opens, but Crashes almost Instantly. OS: Windows 11 (Build 23H2)

Hello, I have problem with firefox. When I try download from facebook page files .docx, .xlsx (Microsoft Office) Firefox automatically download it as PDF and file is broken. I don't know how to repair this. Please help, it is very frustrating.

I'd like to be able to open a link in private mode by holding down some modifier key, then clicking on the link. There are many times that I want to open a link in private mode, and a keypress + click would be the quickest way to do it given that one hand typically remains at the keyboard while I use the mouse/trackpad.

I've even added a toolbar button to open a new private browsing window, then dragged and dropped a link onto the button, but that gets a circle with slash icon and nothing more.

Others have asked this question, so, to be clear, none of the following address my question: copying the link then opening the private browsing window & pasting the link, using a customized shortcut/bookmark, opening Firefox in private mode via command line, right-clicking the link then selecting "Open link in new private window".

Thanks for any advice and thank you, Mozilla, for Firefox!

Ever since the update, I have had pink flickers on videos on youtube and twitter. They last for less then a second, so I couldn't grab a screenshot of it. After doing some reading online, I turned off hardware acceleration which turned the pink flicker black and now effects several sections of the web browser.

Hi,

I'm using FF on Fedora 39.

However Firefox does not remember any file associations. The MimeTypes.rdf file in the profile is missing and is also not created on restarting the browser.

In the options I've now set the configuration to "Ask whether to open or save files". Now I see a popup when clicking on a file however there is no checkbox with "remember this file associations" (or something similiar).

Hello,

When I go to update Firefox through the settings > general > firefox updates > check for updates, I am getting the error in the title. I can manually download the app installer and update to the most current version which is what I did for version 125.0.1, yesterday.

I have tried uninstalling and reinstalling firefox, installing the beta branch, refreshing firefox, running in troubleshooting mode, completely deleting all user firefox files, and I still get the error. No DNS resolver issues to the update server. No firewall issues. No network blocking (tested with other devices).

This issue started after March update to 124.0.1 and continues to current stable release 125.0.1.

This issue also seems to extend to checking for extension updates.

Below are browser logs for when i try to check for update or update extensions.

I use a web application that lists items in a table, which provides a link to download the table as a CSV file. It used to work fine in previous versions of Firefox. However, in the current version, while the file save dialog defaults to a filename that ends in .csv and CSV is selected in the "Save as type:" drop-down, the data in the file that Firefox actually saves is in XML rather than CSV format. I don't know in which version of Firefox this behavior changed, as it's been a couple years since I tried to use this feature. Or I suppose it actually could be a new bug. I do know that when I use the same feature in Microsoft Edge, it saves the CSV file in the correct format, so this behavior seems to be peculiar to Firefox, rather than anything wrong with the web application.

This link does not fully load using Firefox, but does using Chrome.

As of an hour ago suddenly all of the usual suggestions and autofill with bookmarks in my address bar are wrong and out of order. I didn't close out of or update Firefox, I was just browsing online. I didn't change anything in my settings or have opened that up in days at the minimum. I cannot figure out how to either revert back or tell Firefox to not show me these choices so I can get my old ones.

I'll give an example: When I typed in "ma" it would show me mangadex.com, which I often go to. Now when I do it not only is 5th on the list it shows up and fills in "https://www.manticgames.com/", which I don't have that specific page bookmarked. I have "https://www.manticgames.com/games/kings-of-war/" bookmarked, but not that homepage. But now all of a sudden it is showing me the homepage of that site when I begin to type in "ma".

This is incredibly irritating and I have no idea why it's doing this at me out of nowhere. I don't want about anything showing up besides my bookmarks and specifically only the pages I bookmarked.

Hi,

I have Windows OS and use Firefox as my main browser. Firefox settings are set for dark mode and it works in google.com etc, but when I open iCloud Notes, it's full white and not in dark mode. Can someone advise how to change iCloud Notes also to dark mode? I have cleared cache etc, not helping.

I have a unique annoyance wherein I use a considerably long email address for many sites. I've gotten tired of typing it out whenever it comes up and wish for it to be preserved as an autofill across all sites so I no longer have to, similar to how your phone may suggest your email address in autocomplete.

Unfortunately, as far as I can tell, you can only manually add autofills for specific sites and with password attached. So my question is, is there a way to make the address be a suggested autofill on username/email address boxes across all sites?

Hi

I've been having an issue logging into Gmail using Firefox. I've used both Gmail and Firefox for years and have never had a problem, but I now get stuck in an endless loop on the Gmail login page. I select my account, enter my password, then get sent back to the account selection page.

The problem seems to be relating to me trying to link two Gmail addresses so that mail from one is forwarded to the other. I set up one account this way without any issue, but when I went to do it with a different account, I got an error code. After that, I was logged out of Gmail in Firefox and haven't been able to log back in.

Things I've tried so far:

• Using a different browser. I can log in without issues in Chrome.
• Logging in with a different method. Neither my password nor my passkey work.
• Logging in with a different Gmail account. All of my accounts seem to be stuck in this way.
• Disabling all my extensions. This doesn't help.
• Clearing Firefox's cache. No luck here.
• Restarting Firefox and restarting my PC. Turning it off and on again doesn't fix it.
• Contacting Google support. They said they think it's a browser issue as I don't have any problems using Chrome.
• Using Firefox's private browsing mode. This does work and I can log in to Gmail. However, I don't know exactly what the problem is because I've disabled all my extensions and cleared the cache in regular browsing mode and still can't log in that way.

So I have a partial solution (using Firefox's private browsing mode) but it's not a long-term fix. What else can I try? Has anyone else seen this problem before and been able to fix it?

Anyone else had the problem of not being able to sign in to the Amazon Parent Dashboard via Firefox? But works on Chrome. Same on desktop and android versions of Firefox.

Amazon chat support not helpful and just told me to use Chrome!
