Everytime I load Firefox the bookmarks sidebar is not shown.

Navigating thus View => Sidebar => Bookmarks I can bring it up. It will stay visible for the whole of my browser session. However, after I've closed this session and started another. the bookmark sidebar is missing again.

How can I make the bookmarks sidr be available all the time?

FF 127.0.2 OS Windows 11 Pro v 24H2 Build(26100.994).

after creating a new profile, and copying everything in the root directory to the new profile, including search.json.mozlz4, the default search engine setting does not get transferred over and is still set to google

Hello,

I am hoping that there is a way in which I can organise (permanently, not just the current display) my bookmarks alphabetically though still separated by folders and bookmarks. In case that isn't clear, the order would be:

1. 1 all of the folders grouped together in alphabetical order, then
2. 2 all the bookmarks grouped together in alphabetical order.

Thanks in advance for any assistance you can offer.

One of the add-in permissions is "Access your data for sites in the “named” domain". I looked at that and thought, "That certainly cannot include passwords"; BUT the explanation for this permission is: "The extension could read the content of web pages you visit in the specified domain, as well as data you enter into those web pages, such as usernames and passwords. "

I was stunned.

That means that addins that get this permission have access to my banking/medical/etc. usernames & passwords. This is not acceptable. Can a permission be developed that would be: "Access your data for sites in the “named” domain" (except usernames/passwords).

The permission "Access your data for all websites" is significantly worse in that it applies to all sites.

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”?

When you check the image, you can see two "HOME" entries. This is an issue I discovered after uninstalling and reinstalling the Firefox browser and using Sync.

HOME is my PC, and this image was screenshot on my laptop.

Additionally, the Sync for these HOME entries is not functioning properly. I tested this by opening several sites, and while Sync works well from my smartphone to my PC, it doesn't sync properly from my PC to my laptop.

Does anyone know how to solve this problem? I tried rebooting my PC, but it didn't work out.

If you are currently using a normal window then there are ways to open a bookmark or link in a private window. But if you are currently using a private window then how would you open a bookmark or link in a normal window?

I have tried several things including pressing shift+enter or choosing "Open in new Window" from the context menu, but this just opens the bookmark or link in a new private window.

My current method is to copy the address of the bookmark or link then paste it into the address bar of a normal window.

But is there a more direct method of opening bookmarks or links in a normal window, if currently in a private window?

Thanks.

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?

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.

Is about:config > app.update.auto set to false sufficient, How to Disable Firefox Update Notifications: A Step-by-Step

Or how about the registry? Turn Off Update

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?

I'm using Firefox 127.0.2 on Arch Linux. In settings under General>Startup>"Open previous windows and tabs" is not checked. Under about:config browser.sessionstore.restore_on_demand is false, and browser.sessionstore.resume_from_crash is false

How do I get Firefox to give me a clean slate after restarting my computer?

Hi. i ran into a broken problem. sometimes when i bootup my pc and start the firefox, My windows crashes immediately. what shuld i do and how i can send the firefox log files to mozilla team?

I installed Firefox on a Macbook Pro with Apple Silicon, M3. The installation was from the Firefox site, I downloaded the dmg and then dragged into Applications.

I find that playback of media stutters, and is choppy--not sure of a better way to explain it. E.g., YouTube videos and the Bandcamp player have "stuttered sound". Opening another site in another tab can make this effect worse. Likewise, trying to run Google Meet in a browser window causes basically everything on the computer to become very slow.

This still happens even if I go to "about:profiles" and then "restart with add-ons disabled".

But if I switch to another browser, Safari or Chrome, then I don't have the issue. e.g. I can play YouTube in the background fine even when running some compute intensive task.

I have also tried turning on/off "performance settings" and the "use hardware acceleration" checkbox underneath it -- neither of those seem to have any effect.

Activity Monitor showed that at most Firefox was using ~4 GB of memory of a total 48 GB, and the memory pressure indicator seems to be quite low.

I have run Firefox on other systems (e.g. System76, older Macbook Pro) with multiple windows open each having 20-30 tabs and never had an issue like this.

It really seems like it has something to do with how Firefox is interacting with the M3? Happy to learn I'm wrong. And happy to provide more details about the hardware or my settings if it would help.

Some shades of white have a purple tinge to them. The amazon logo, certain themes, and other websites are slightly purple. This is only an issue in firefox, not any other program or browser.

Regular download works fine, but when I try to download attachment in outlook.live.com website, it didn't ask me where to store it, but simply places it in my default location, while at the same time opening the attachment even though I only want to download the file.

Problem: When exporting or downloading content from the GUI in the digital forensics tool Velociraptor, underscores are appended to the beginning and end of filenames. File is otherwise downloaded correctly, but removal of underscores necessary if original filename is desired. One hypothesis is that perhaps for security reasons there were changes made in Firefox 127 for how character escaping is performed.

Tested Operating Systems: Ubuntu 24.04, Windows 11 22H2, Windows 11 24H2, macOS Sonoma (14.5) Affected Firefox version(s): Confirmed 127.0, 127.0.1, 127.0.2 Tested Firefox versions which do not reproduce the behavior: 126.x, 125.x > Testing Microsoft Edge, Chromium, Google Chrome on Windows, macOS, Linux: files download with correct name as expected. Testing performed with clean installations on clean VMs with no add-ons enabled.

To reproduce: Download the latest release of Velociraptor from Github (at the time of this writing, 0.72.3) for preferred platform / operating system. Run Velociraptor using the gui switch, e.g. "$sudo velociraptor-v0.72.3-windows-amd64 gui" or "$ velociraptor-v0.72.3-windows-amd64.exe gui" Navigate to Server Artifacts and click the "+" icon at the top Search for Server.Utils.CreateMSI - select and press Launch Select the newly-created flow, click "Uploaded Files" tab and click vfs_path to download the file or, click the Notebook tab and click Download JSON or Download CSV buttons to download JSON or CSV respectively, underscores are appended to beginning and end of filenames.

I can no longer download pdf's (bills, statements,etc) Downloads come in with "name.pdf.part" When I delete ".part" then I can open file. If I don't change name it reverts to pdf.part extension. It's a pain renaming every download. Please help me, I don't want to switch to Chrome. Thanks!

When I try to access an http:// site, the link is upgraded to https:// regardless of this setting.

This broke after a recent update to the browser. I cannot specifically say which upgrade, but it worked a month ago, now it doesn't anymore.

It may be worth noting that this broke in Brave (based on Chromium) at the same time.

I keep getting the error in the image and can't use my tabs at all . The search loads for 10-15 seconds and then I get the error. I have tried troubleshoot mode too !
