HI all! Hope you all are doing well.

I am using user.js file to harden my Firefox to the best possible way. I have few question about that process.

1. Where i can find the complete list of all active user_pref settings? All of the options i have to edit them. like user_pref("security.sandbox.content.level", 6); - now i have 6 by default but what is the range?

2. Is there any tool i can use to update my list with the latest entries, and to remove the obsolete entries?

3. Sandbox - what are the best possible ranges and settings for the below entries?

ser_pref("security.sandbox.socket.win32k-disable", true); user_pref("security.sandbox.content.level", 6); user_pref("security.sandbox.content.shadow-stack.enabled", true); user_pref("security.sandbox.gmp.win32k-disable", true); user_pref("security.sandbox.gpu.shadow-stack.enabled", true); user_pref("security.sandbox.gpu.level", 2);

Thanks well in advance! Firefox 116.0.3

Until recently, this extension had worked well on YouTube, where downloading videos has usually worked for years without an issue.

However over the past month or so, when using the Linux system, it's become impossible to download any video from YouTube, without an error popping up after a couple of seconds.This occurs whatever choice of aspect for a video is available, be it in mp4 or mkv format. I should emphasize that this issue only seems to occur on YouTube. Other unrelated sites that host video-sharing still work with Linux.

In Windows 10, Video DownloadHelper with YouTube still seems to be working as normal. So any ideas why I can no longer use this extension with Linux and YouTube?

Regards,

Gradually I am losing all ability to use Firefox for financial and vendor payment logins. One by one over the past year I get varying messages that keep me from logging in. Chrome (which I don't care for) works in each instance. Yesterday Vanguard denied me, stating THEY are experiencing technical difficulties, apologizing for the "temporary" inconvenience. This message has been coming in for six or seven months at login but I was able to try again and it would let me in on the second try. Recently, a Vanguard rep suggested clearing my cache, which I tried successfully last week. Yesterday, I received the same message and clearing the cache failed. I love the Firefox structure and feel, and it's keyboard shortcuts, but I can't be fooling around like this every time I try to log in. This has now happened with a number of vendor payment accounts, my banking login and now Vanguard. How do I fix this?

I use FF 116 on windows 11. For months, I have had problems logging in to web sites. At first I thought the problem was with the web site, but I have come to the conclusion it is an FF problem. GlobeandMail.com, gem.cbc.ca and rbc.com for example ask for me to log in. I go through the steps giving my password and login name and the web site seems to accept these without complaint but it continues to want me to log in. I end up having to use Edge which works fine. Is there a solution?

I believe I had originally installed Firefox while I was in the UK. Since then I've moved to the US. When I type "amazon" in the location box, the first option is "amazon.co.uk". I've looked for options to change this to amazon.com. I cannot remove it (there's no "..." to the right). I've downloaded and reinstall Firefox now that I'm in the US. I made sure my default language is English (US).

One thing I can't done is completely uninstall Firefox and then reinstall. I'd rather not lose any settings and so am saving that for the last resort.

Anything else I can try?

I have the latest version of Firefox for Windows 10. I accidentally sorted my bookmarks by name (hundreds of them in a folder called Other Bookmarks) and want to go back to unsorted...but no matter what I do, even if I check the "unsorted" option, the bookmarks stay in the "sort by name" alphabetized mode.

How do I fix this?

Thank you

Nick

Up until Firefox 116, Reopen Closed Tab (Ctrl+Shift+T) would reopen closed tabs, and Reopen Closed Window (Ctrl+Shift+N) would reopen closed windows. There was a clear bifurcation, so I could freely close windows and not worry about it polluting my tab history in another window.

The latest change has thrown out that advantage, and now Reopen Closed Tab reopens both tabs and windows, while Reopen Closed Window still just reopens windows. This makes the later essentially useless and the former much more difficult to use for me.

I assume this was done to just continue copying Chrome in all respects since that's how it handles it, but the changelog just vaguely states, "This change is in anticipation of upcoming changes to recently closed tabs."

Does anyone know if there's a setting to separate the two functions again?

I recently came back from vacation when i started up my pc and so firefox all my tabs ands things automaticly opened like normal also a page with my saved passwords but it was empty all gone.

All my saved logins/passwords gone. I have searched on the forum and tried all the solutions given. Like the logins.jason.corrupt file i have 10 of those files in my folder but there all empty tried all of them. also tried switching profiles checking other profiles nothing to be found there either. im clueless and im in desperate need of these logins please help me ..

The last Walmart questions are 2022, so again... When I click a link to Walmart, for a second I see the full site displayed correctly on my desktop monitor, then it shrinks to about half to the left side. Windows 10 up to date, Firefox 116.00. Enhanced tracking, whether on or off, doesn't matter. Walmart is the only site I have this issue with. Is it Walmart's fault?

I didn't know if this needed to be in Privacy and Security Settings or Cookies, so please feel free to move this to wherever it fits best. Here is my problem. I have saved logins on a lot of sites that all work perfectly. There are several websites that I have multiple accounts that all have their login credentials saved. My problem is that there is one specific website that until recently was operating just fine, but in the last week has started a nuisance issue. When I log into the website I select the login profile I need and everything starts off just fine. About 5 minutes later, whatever I am working on gets hijacked by a dropdown appearing in the upper corner of the screen that lists the six logins that I have for that website. If I continue to try typing, nothing happens (as in, the dropdown list stays there and whatever form I was typing on no longer has any data being entered). If I press ESC, the dropdown list goes away but it also closes down the form I was using. If I use the mouse and click anywhere on the screen, then the dropdown list goes away and I can continue using the form I have open. About 5 minutes later, or if I open up a new form, the dropdown list comes back and I have to do this all over again. I have talked to IT of the website and they stated that they have never seen this issue before. Other users that also use Firefox have never mentioned this to them before. Is there a setting that I need to change? Do I need to clear the cookies for this website? Do I need to just delete all of the saved login information and then re-save it? Thank you for your help.

I noticed today that a video hosted on the website Reddit has subtitles on it. When I view the video in other browsers it does not have subtitles. Why are subtitles being generated in Firefox for this video? Is there a way I can disable these subtitles? While often useful, the subtitles in this case just get in the way.

If URLs are allowed one example is here: https://v.redd.it/z7tekckuy9hb1

Thanks.

After a recent change of my website's name registrar, Firefox (both on Linux and Android) has been running into issues finding the server/address. I suspect this has something to do with DNS, whether it be DNS over HTTPS (DoH) or otherwise.

Specifically, this seems to happen when DoH is on (as shown by about:preferences#privacy). I have confirmed that `curl --doh-url <cloudflare DNS query> <my website>` also fails to resolve the request.

This leaves me with a few outstanding questions:

• Do I have any control of whether the DoH request fails? Is this something I can fix through my host or name registrar?
• The TRR mode shown in about:preferences#privacy appears to be different than the one shown in about:config (2 versus 0, respectively).
• Shouldn't Firefox be falling back to normal DNS? I have confirmed via `curl` that my website works fine over https.

Firefox and curl results for Linux confirmed on two machines on the same network.

I have windows 7. On August 1 Firefox automatically uploaded version 116. Now my computer is running very slowly, and is taking a long time to load pages on the internet when I browse the web. I just learned searching the web (I never go any notification from Firefox) that version 115 was going to be the last version for windows 7, so how did I get version 116 automatically loaded onto my computer? How do I go back to version 115 which was working great? I right clicked on the Firefox icon on my desktop and clicked restore previous version and it states there is no previous version there. How do I go back to version 115.

When posting on vBulletin forums, Firefox (116.0.2 on Windows 10) inserts and extra line upon pressing the Enter key. The fix for this is reported on the 'Net to be to alter variables in about:config.

I've attached a screenshot of settings on my system as reported by about:config. My questions are . . . 1) What, exactly, does the bottom line in screenshot mean? If I display All in about:config I find no Newline entry? What effect, if any, does changing values among the choices do? Do they affect the other settings? How? 2) What effect do the other 2 settings as shown have on entries typed in Firefox? 3) Are there changes that I should make in the top 2 variables that will stop the extra line insertion?

TIA

I am signed in with this email on another computer. The only idea I have is firefox is rejecting the email format before even checking the email.

Please help, thanks.

I had about 100 tabs open but when I opened up my bowser they had disappeared from the 'Recently Closed Tabs' list and the vast majority don't appear in my History.

How do I recover the Tabs?

TIA

Hi everyone,

I have permitted a website to access my location, but Firefox is not retaining the settings. While I am on the web site I keep getting the "Allow www to access your location" popup several times in a row and the website still reports that I need to enable the option. This is happening to all websites, not only this specific one.

What I have done thus far:

Restarted Firefox Refreshed Firefox Rebooted my computer Cleared Firefox cache and cookies Confirmed under Settings/Privacy & Security/Location that the site www status is "Allow" Removed my ad block settings from my router as I don't use a local add on

I am using Firefox 116.0.2 (64bit)

Thank you!

New Laptop, new Windows 11 - and running permanently into the issue of having to sign into windows security, when trying to open Firefox. If I click it away - it provides me with the firefox browser but its original set up. To get to "my firefox browser" set up I have to log in. I cannot find anywhere in the Microsoft settings the possibilty to remove Firefox from this requirement. I have tried to unstall and reinstall Firefox, also reset Windows security (which is a joke - as nothing is reset). Can you tell me how to get ridd of this - so that I simply can open the Firefox browser without having to fall each time over Windows Hello. (I have tried to unsign from Hello and use on the classical password sign in - no hope - still asking then for the MS password). Firefox is in some super secure vault - and I would like to get it out of there.
