Prior to update 125.0.1 corporate intranet users could download PDF files from our Line of Business applications / Webpages. Today after the latest update the PDF files download but are corrupted. The site was added to the trusted webpage without improvement.

Adobe Acrobat Reader could not open ********.pdf because it is either not a supported file or because the file has been damaged

When I open github it loads incorrectly as shown in the picture, after I press F5 to reload the site load fine. I have tried deleting cookies and I am using any ad-blocker. Any help? Thanks.

I tried to login to firefox sync on a different system due to repair. My entire data is gone and all passwords are also gone. What to do.

I even tried login with username and password apart from google sync. It still didn't worked.

Hi, Before Firefox's Version 125.0.1 (64-bit) latest update I could download any file from my safe office environment, behind firewalls, VPN, ... Now despite of unchecking the "Block dangerous downloads" I'm still unable to download files. I have Windows 10 on my laptop.

Here are the steps: Click on a file, Save "File not downloaded. Potential security risk." Click on the message - Allow download The result is a file with content "HTTP Status 405 – Method Not Allowed".

Please help me to work the downloading again. I am aware of the safety but I want to switch off this feature.

Thanks in advance for help, Tibor

My computer messed up today and i had to recover it, but i didnt get to save my bookmarks. I've had a mozilla account since 5/2/2024 (i think, thats at least what it says was the date i made my password) and i've saved a lot of bookmarks i cannot lose.

i forgot what email i had made it with tho, so i created a couple of new mozilla accounts and idk if that has messed up the profiles i'm using? i read the mozilla guide on bookmarks and i have like 3 profiles under "profile:default-release" (my settings are in danish, idk if that's what its called in english). but i cant tell which one it is? furthermore, when i click on "manage bookmarks" i get to this place that says something about bookmarks saved on html or something - which i know i havent done.

oh also, before any of that, the first thing i did was synchronize my google chrome bookmarks with firefox and idk if that has messed something up?

Hello. I use youtube website as music player quite often (without premium) and play my favorite list of songs. Meantime, when Google started meddling with youtube due to their new offer as youtube premium I met two most annoying issues like "are You still watching" dialog and the behaviour where youtube just cleared "repeat list" function without my consent. Both issues was resolved with java scriplets I took from community.

Now I run into third issue but not sure how to diagnose it. If Firefox is in the background, or tab with youtube has no focus the playlists stops from time to time. The moment it stops is when next video should start playing. When browsing on different tab, I can see on Youtube tab that title of the video has changed (to the next video) and even the song started (for 1-2 seconds) then video pauses and word "playing" disappears from tab (normally there should be title on tab and "playing" word under title). It is not "are You still watching" dialog issue because if I move mouse cursor on youtube tab (even without setting focus on it) the player will continue - till next song.

The issue doesn't appear if youtube tab is active. I can't use developer tools in firefox because can't debugging website when tab of the site is not active (at least I don't know how). I tried to find solution with community but with no success. I allowed youtube to play video and sound always without exception in firefox preferences but it is not the solution.

Any tips?

Every time I restart firefox, my spellchecker languages disappear, leaving me only with one - the addons are still installed, they're just not available to be selected. Even now I can't spellcheck in english. Please help.

Currently, I use Firefox version: 116.0.2 on Ubuntu 20.04.6 LTS.

I encountered a phenomenon like this:

• When I logged in to the application, in the tab I was working on, the Firefox session memory was lost (don't open new tabs)

What is the cause of this phenomenon? How can I fix it?

I did an Upgrade to a version of Firefox that would bypass those "Your Browser Is Not Supported" messages that apparently come from "Cloud-flare." I figured [naievely!] that my addons would "port" to the upgrade. They didn't. Is there any way [e.g., a putative backup file, perhaps] that would allow this?

Thanks in advance...!

latest 124.0.2 causing severe problems, it will near instantly bloat to fill all RAM and SWAP even in safe mode causes system load over 24! only solution is to reboot very problematic on for ex: https://epg.pw/xmltv/epg_CA.xml hard to get a screencap since system is nearly totally unresponsive. RAM is ok SSD is ok MX Linux is ok

I recently have gotten a message about manually updating Firefox on my Windows 11 system. Even after I updated, I then I started getting the same message and also "Failed to check for updates" in the Firefox "about" box and settings page.

I even went about uninstalling Firefox and reinstalling it while deleting the Firefox Program Files and user AppData directories. I also checked for a Windows Firewall entry for the program.

Is there something in another directory or registry setting I need to delete or change? Or does Firefox use a different program for updating that needs a firewall rule?

Thanks for any help.

I accepted this the other day but now don't want it. It is a Print popup & at bottom says Grow I can not find how to remove this. Popup shows this: Unlock the Print Button!

Cannot delete cookies nor cache due to a grayish button. First it works fine, after a few hours, buttons are gray.

Also sync seems not to work anymore when this happens.

Can you recommend some kind of extension thet will only check current icons for the bookmarks? Just that. I don't need duplicate bookmarks checker, inactice checker and God knows what else checker. Just icons, that's good enough for me.

I've been using Firefox home content shortcuts usefully on my Windows system. I installed Ubuntu on Vmware last night and synced Firefox account in it. After that, the home content shortcuts are all changed to the default status. I think it's because that I clicked the sync now button on Ubuntu. Is there a way to roll it back? Thanks.

I am having a new (to me) problem logging in to Flickr using Firefox on my laptop (running Windows). After supplying the requested email and password at log in, I was prompted to enter a verification code that was sent to my account email address. After promptly entering the verification code, I was returned to the original log in page. There was no error message to indicate that either the address, password, or verification code were incorrect or that anything else had gone awry. I was simply not logged in. I repeated this process a few more times with no change.

Then I tried two other browsers (same laptop) and logged in sucessfully without even having a prompt for verification code from Flickr. I also have access to the account through the Flickr app on my phone. I am not sure then what Flickr is encountering with Firefox in particular. Any suggestions? Thank you.

Issue: The "Recommended stories" setting for the new tab default home page periodically re-enables itself.

Version Info: Firefox 124.0.1 (64-bit) OS: Linux Mint 21.1 Cinnamon

Additional Information:

• I do not use pocket, at all
• All settings that I can find related to pocket are disabled
• I do use Firefox Sync, however the other device (124.0.1 (64-bit) on pop_os!) does not have this issue
• Does not correlate to version updates (Mint has automatic updates disabled in policies)
• Does not occur after a simple restart

I am tired of disabling this setting and having it return seemingly randomly. I have no interest in these stories, and consider them spam.

Please assist me in determining why this is happening on this device and how we can go about preventing it going forward.

Thanks, Steven

Hello everyone, I’m a fan of Firefox due to its efficient handling of webpage caching and memory management. However, I often find myself switching back to the Chromium-based Edge browser due to one specific feature in its DevTools. In Edge, when I resize the viewport, it stops at a certain limit. If I want to resize it further, I can zoom out and then continue resizing. I find this feature very useful. Is there a way to have similar functionality in Firefox? I’m currently using the Firefox Developer Edition.
