Firefox Support Forum

I am a web dev and have a user download link to an excel xlsx file. On my own system it downloads fine in Chrome but in firefox ot displays the raw contents. Is this a FF setting?

Firefox does not retain email login addresses for Fastmail email webpage.

I have used Firefox and Fastmail for many years and this has never been a problem. When I opened Fastmail previously and placed my curser on the email address box I was always presented with a choice of three or four email addresses. However now I am only presented with the first email address I entered since the Fastmail/Firefox upgrades.

I have contacted Fastmail about this and they suggested it might be a Firefox issue

Hi, i have formatted my macbook pro, before i have made a back up with timemachine. I'd like to restore my bookmarks but i can't find it on the back up. I have tried to find on Library>Application support but in this folder there is not the Firefox folder in wich i expected to find the Profile folder.

Problem: Persistent 150 KB of Cached Web Content For several years, I have gone to “Settings” / “Privacy & Security” / “Cookies and Site Data,” clicked the Clear Data…” button, checked both “Cookies and Site Data,” and “Cached Web Content,” and clicked “Clear”, and consistently gotten BOTH “Cookies and Site Data,” and “Cached Web Content” down to “0” zero. Recently, I have been unable to “Cached Web Content” to go below “150 KB of disk space.”

         I have NOTHING listed in “Manage Cookies and Site Data” or “Exceptions -- Cookies and Site Data.”
         I have tried reinstalling, but the problem has persisted.
         On the assumption that this is malware problem, I have continued to use Mozzella VPN, but stopped using the program for browsing, etc.  Should I stop using it altogether until the problem is fixed?
         Can you tell me how to get rid of the last “150 KB” of “Cached Web Content”?

Using windows 11 on a desktop PC. Firefox has been my default browser for decades...issues have been very rare. But this is a catastrophic problem. One of those folders contains links to equipment mfrs, the other one has links to dealers and retailers. In the last month TWO folders and all their contents have vanished from my bookmarks sidebar and cannot be found anywhere on my computer. I NEED those folders...Where did they go and how do I recover them ?????

Help to do that will be appreciated!

I switched back to release from nightly because the themes support completely broke rendering of menus, buttons, etc on various (read: pretty much every single one, including this one) websites, making them difficult or impossible to use. I've tried a browser refresh to no effect.

unfortunately, it appears the feature has been rolled out to release now as well, as pictured below.

I've tried cycling through themes, setting custom colors and forcing it to never replace the website's specified colors etc, turning off acceleration... none of it works. this is an issue on my desktop, laptop, and tablet (surface pro x), basically every platform I use except mobile.

any ideas how to fix this? it's really annoying and I'd really like to not hop browsers again, I've been using firefox for a good long while now.

Dear Team Kindly help me for retrieve my details bookmarks and passwords very important to me.

One of the typical configuration in linux is to turn off the user namespaces and/or network namespaces. This is because most of the exploits in linux have been related to namespaces vulnerabilities.

If there is a Firefox ver 127.0.2, running on Linux in which the user namespace is turned off then the following is observed in the Troubleshooting information, i.e. about:support Seccomp-BPF (System Call Filtering) true Seccomp Thread Synchronisation true User Namespaces for privileged processes true User Namespaces false Content Process Sandboxing true Media Plugin Sandboxing true

So how come with the username turned off, the content process and media plugin is still sandboxed? Also is having user namespace turned off, as given above, a security risk?

However if the network namespace is turned off, i.e. max_net_namespaces is set to zero, then it renders the browser unusable. Nothing works. Why is that?

Is there some documentation somewhere where these namespaces and their impact is explained in detail?

Dear FireFox, I am writing this E-mail to address a critical issue. So i wanted to set up a password for my firefox browser so that only I can access it. i set a primary password, and it asks me to enter the password when i open my browser. However, when the message appears asking me to enter the password, you can just click "cancel" option or press 'x' it ignores the password and lets me in the browser, essentially rendering the purpose of the password useless. thus anyone can access my browser. i request you to fix this problem. Regards -SpideyKnight

My laptop glitched while doing a Windows update and it chose to not load certain apps upon completing the update. Mozilla Firefox was one of the apps it chose to delete and I lost all my bookmarks with my login information to all my accounts, can I retrieve those?

I have saved a lot of shortcuts bookmark on my homepage,yesterday when i opened my firefox,it was all gone and it went back to default homepage. what do i do to recover it.

Hello, recently I've been having issues where if misclick anywhere on the title bar (even in the small space between bookmarks) firefox will minimize/restore when I didn't want it too. How do I disable this in about:config?

I'm unsure about this setting. I don't want a tab to reload when it's switched to.

It seems to indicate that something will be reloaded regardless of what I choose. I assume that's probably not the case.

Please confirm.

Good morning, Our company's firefox add-on(Saba Security Plugin) has stopped working, please let me know what happened.

When a new client (version 126) downloads the add-on, the following message is displayed: "The add-on downloaded from this site cannot be installed because it appears corrupt."

If you install an older version, it works without any problems, what is the reason?

I have already contacted you once at: product-help@firefox.com

And they told me to report at: https://support.mozilla.org/questions/new/desktop/form

Regards,

I transferred by Firefox bookmarks from my old computer to my new Windows 11 computer. I think they transferred fine. But to access them, I have to click on Bookmarks and then go down to Manage bookmarks and click on it. Then I see them on the page that has all the Import and Backup access on it. How do I get them to appear in the side panel as a list like they did on my old computer?

hey all. i'm inquiring about how much longer it will be until the URL bottom left corner of firefox on youtube.com bug i reported here is fixed: https://github.com/webcompat/web-bugs/issues/135606 . asking here because i asked on the issue page (the link) and nobody responded :(. thanks so much!

Every time I use YouTube on Firefox it feels like a mental torture. It starts off with micro-stutters initially - annoying but nothing crazy. After some time the loading speed of the website and the videos themselves increase dramatically. And eventually it becomes unusable:

• Scrolling feels like the website is running at 30 fps
• The videos take several seconds to load
• It also takes multiple seconds to catch up when you select a specific moment of the video

The only solution so far has been restarting Firefox entirely, just close and open and pray. Then the problem comes back after some time.

Solutions I Tried:

• Disabling AdBlock (didn't work)
• Enabling Hardware Acceleration at all time (didn't work)
• Uninstalling unwanted Extenstions (didn't work)

All of these problems disappear when using Chrome or Edge.

Notifications/New emails not popping up on Mac OS Sonoma 14.5.

I've tried everything including checking Focus Do not disturb is off, all settings in Firefox and Outlook are turned on to recieve notofictions but still nothing.

I'm on a new Mac Studio, but also found that it had started to not show notifications on the older iMac.

Thanks
