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?

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

After installing Thunderbird i had first download problems for new Firefox Versions. I tested around, installed everything new and found the solution. Somehow the Maintenance Service didn`t work properly on my machine and after deinstalling and restarting i can update firefox again. Problem remains: When trying to install Offline Languages , see picture, i get the message that it does not work. I tried everything possible, including reinstalling and deleting all old profiles (was a lot of work). Any ideas?

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 have used Firefox as my browser for many years and lately my emails won't open or if they do it is very slow sometimes and won't allow me to delete emails. Not sure why this is happening and I asked by email provider and they told me to follow some instructions about fining the menu button of Firefox which I couldn't find then he gave me a link and I tried to follow but was unable to make any progress. I use spectrum email services

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.

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?

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.

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...!

Every time I would try to log in it would always redirect me to a website that contain only the words "Expected redirect cookie to exist"

It's really annoying because it only happens on Firefox. For some context I just re-installed Windows 11 and I heard from another post that re-installing Windows 11 will help but I do not want to go through the whole process again.

I have already tried:

• Turning off DNS over HTTPS
• Turning Off Proxy
• Clearing Cache and Cookies
• Reinstalling Firefox

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.

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.
