Firefox Support Forum

For System Administrative reasons, I want to disable automatic Firefox updates. Firefox can ask me if I want to install an update, but I get to choose whether or not to update.

i am setting up a new laptop and trying to import all my current data from my old pc. Nothing is right. It imported alll the shortcuts on my toolbar from years ago. None of these are the current bookmarks from my old pc. ive tried syncing, importing again, nothing works. my bookmarks on my side bar are years old. I dont have ANY of these on my old pc as i deleted them years ago. what the heck is happening and how do i get my new pc browser to look exactly as my old pc looks. This is very frustrating. I have over 500 bookmarks on my sidebar. it looks like every bookmark i have EVER used. This is ridiculous.

For some time now, I've been experiencing the following issues with PiP:

• The floating window opens in a random (and annoying) place and does not place itself automatically on the lower right corner as it used to (where I always move it, so it has no memory as it used to)
• It's impossible to keep the "always on top" mode on by default, and I have to do it every single time
• When I toggle windows, the PiP window is always the next one, even when it was not the one I switched from, and I have to always toggle twice for switching between two windows when I have a 3rd PiP window
• When I change language using the keyboard shortcut, it changes the language on the PiP window, and I have to use the language icon bar. Then, the PiP window becomes activated, and I have to toggle back to the window I was working on before (on which I wanted to change language). I have the "separate languages for separate windows" option activated.

It's been some months now, and all those things were working before an update but never came back...

Does anyone know if there's a way of fixing these issues? I've tried things I found online but nothing seems to work.

Many thanks

I can login from other web browsers, but not Firefox. What's going on?

When I try to login as I have always dine in the past, this is what comes up: https://outlook.live.com/mail/0/

But then absolutely nothing happens. Please advise.

My Firefox settings are configured to "Open previous windows and tabs" on Startup. This worked fine until this morning, when I lost all of the tabs in my session, including the pinned ones. The last time I closed Firefox, there was only one window open.

I have already tried these ideas to restore the tabs:

• CTRL+SHIFT+T: Does nothing
• CTRL+SHIFT+N: Does nothing
• Three bar menu -> History -> Recently closed tabs: The list is empty
• Three bar menu -> History -> Recently closed windows: The option is greyed out
• Three bar menu -> History -> Restore previous session: The option does not exist in the menu
• Open user profile folder and open sessionstore-backups folder: There are three files named "previous.jsonlz4", "recovery.baklz4" and "recovery.baklz4". They are each 2KB and contain only an empty tab with the URL "about:home". There are three additional files starting with "upgrade" but they are from too long ago, so they don't contain the tabs I require.

The contents of these tabs are vitally important for my work, so this is causing me significant stress. If anyone can suggest ways to recover my previous tab beyond the documented fixes, I would greatly appreciate it. Thank you so much to anyone who can help!

Hello dear community,

I have a program that continuously monitors the download folder under Windows 11 for a specific file and retrieves it. I download this file in Firefox, but the said program gives an error.

I have noticed that when files are downloaded in FireFox, they already appear in the Downloads folder with the corresponding file extension with 0 bytes and these are then apparently swapped or merged with the .parts file.

The problem is that the mentioned program now tries to retrieve the unfinished file, which then leads to an error.

Does anyone know if it is possible to customize Firefox so that the file only appears in the download folder when the download is fully complete?

Many thanks for your help :D

For a few weeks now, FIrefox will not play DRM content video on this computer. I have tried all the suggested solutions and none have worked. Also, I uninstalled and reinstalled Firefox, but the problem remains. I am very frustrated with this problem and am ready to get rid of Firefox permanently on ALL our computers unless this can be fixed.

Thank you in advance for your assistance.

Hello guys, so in the past 2-3 days i started facing Cross-Origin Request Blocked for a lot of websites lets take chatgpt for example, if i visit it i get:

Content-Security-Policy warnings 2 Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://cdn.oaistatic.com/_next/static/chunks/sso.74deac81d652476b.js?dpl=f90a861ef09abad575887be5d613ce15a4fdb6d9. (Reason: CORS request did not succeed). Status code: (null). The resource from “https://cdn.oaistatic.com/_next/static/chunks/sso.74deac81d652476b.js?dpl=f90a861ef09abad575887be5d613ce15a4fdb6d9” was blocked due to MIME type (“text/plain”) mismatch (X-Content-Type-Options: nosniff).

and its getting so annoying that its blocking a lot of websites, i tried chromium it works fine and works awesomely no cors no problems. I even tried to disable the firefox protection, dns over https on/off, change my main dns upstream, installed firefox developer, compete uninstall/reinstall, cache clear from installers and from firefox it self nothing is working. I will provide firefox developer edition troubleshooting information but keep in mind it doesnt work on both firefox normal and developer

Please any help would be appreciate it.

Firefox v124.0.2-1

when I search for a page after opening a tab. The page will load slowly then stop. I'll then have to hit enter again for the page the load. This does not happen with Chrome or Edge. Any ideas how to fix this frustrating issue. Thanks.

The latest version of firefox for MacOS 14.4.1 has broken the picture in picture function. When enabling PiP, the video window takes up almost the entire screen and doesn't remember the size i set it to, like it did in older versions of Firefox. Another issue is when im in fullscreen mode and enable PiP, the PiP window takes me to another 'desktop', whereas before it would simply overlay on top of my screen.
