How do I keep my online banking private when using Firefox as my browser? When using Google Chrome as my browser, I use incognito, but I'm changing to Firefox and need to know that my online banking is safe.

I run Firefox on a retro Linux system that is currently running a personal "Frankenbuntu". Basically, Kubuntu 14.04 LTS with lots of components updated either "in-tree" or via a pkgsrc-like collection of "ports" installed under /opt/local that includes GTk3, Mesa, VAAPI plugins etc. I use that tree with a combination of built-in rpath settings (for apps installed under /opt/local) and wrapper scripts setting LD_LIBRARY_PATH, so as to maintain the possibility to run system apps independently, in particular while booting. (Sounds complicated, but it's also a rewarding fun project for me, allowing me to keep using an old and familiar DE with modern features on 2017 hardware,)

I have never yet dared to update my glibc from the stock 2.19, so with every Firefox update I fear to run into problems with that. I do have a 2.27 build but that is installed in another parallel prefix (/opt/glibc/2) because one cannot simply use LD_LIBRARY_PATH to use a newer glibc (I think because the ELF interpreter, ld-linux.so, has to match).

I already use patchelf with success to change the ELF interpreter to the 2.27 one, for instance with Ferdium, a Node/Electron application. This works and as far as I can tell, it will load all Mesa and DRI components from my /opt/local tree so hw-accelerated video works as it should.

But when I try this with Firefox, I get what appears to be a sandboxing issue when attempts are made to load Mesa DRI libraries: ``` libva info: VA-API version 1.24.0 libva info: Trying to open /opt/local/lib/dri/iHD_drv_video.so libva info: Found init function __vaDriverInit_1_23 [GFX1-]: VideoBridgeParent receives IPC close with reason=AbnormalShutdown MESA-LOADER: failed to open iris: libsensors.so.4: cannot open shared object file: Permission denied (search paths /opt/local/lib/dri, suffix _dri) failed to load driver: iris MESA-LOADER: failed to open kms_swrast: libsensors.so.4: cannot open shared object file: Permission denied (search paths /opt/local/lib/dri, suffix _dri) failed to load driver: kms_swrast MESA-LOADER: failed to open swrast: libsensors.so.4: cannot open shared object file: Permission denied (search paths /opt/local/lib/dri, suffix _dri) failed to load swrast driver libva info: VA-API version 1.24.0 libva info: Trying to open /opt/local/lib/dri/iHD_drv_video.so libva info: Found init function __vaDriverInit_1_23 [GFX1-]: VideoBridgeParent receives IPC close with reason=AbnormalShutdown ``` Copying libsensors into /opt/local/lib turns the above error into the same one about the next library available in the system (/lib/x86_64-linux-gnu/libtinfo.so.5). The DRI module I actually need (iHD) does load but I still get the GFX abnormal shutdown error. I've tried the interpreter change in other applications using libva and don't see the issue.

I do see this in the syslog: ``` Aug 31 15:18:47 Bmbl kernel: [2043645.959690] MediaSu~isor #1[17692]: segfault at 290 ip 00007f2b0815b284 sp 00007f2ad913e990 e rror 4 in ld-2.29.so[7f2b0814f000+21000] Aug 31 15:18:47 Bmbl kernel: [2043645.959702] Code: 04 49 83 fc 06 44 0f 44 c8 81 e6 ff 7f 00 00 45 89 8f 08 04 00 00 48 8d 04 76 4d 89 b7 00 04 00 00 4c 8d 04 c7 4d 85 c0 74 0f <41> 8b 48 08 b8 00 00 00 00 85 c9 4c 0f 44 c0 41 8b 3e 6a 00 48 8d Aug 31 15:18:47 Bmbl kernel: [2043646.080407] MediaSu~isor #1[17732]: segfault at 290 ip 00007f2b0815b284 sp 00007f2ad913e990 e rror 4 in ld-2.29.so[7f2b0814f000+21000] ```

Any idea why this is, and what can be done to prevent this, beyond actually updating my system glibc? I'd have no problems disabling sandboxing.

A couple days ago when I opened Firefox, I immediately started getting pop up messages saying I had viruses. If I clicked on REMOVE VIRUS, it tried to get me to sign up with McAfee. I cannot see my full screen due to all the pop up screens. My MS Defender virus protection is not identifying any viruses.

Using the "re-open tab" function on a browser based discord instance changed a bunch of my settings, for one it turned on vertical tabs, added extra side bars to everything, and made every ui element animated. Ive figured out of how turn vertical tabs back off, and while I was writing this, I figured out where to turn off this stupid animated gizmo to select what I actually want, instead of directly bringing up my bookmarks/history. How do I stop a random website from overriding my settings in the future? If discord can do it through incompetence another website can surely do it maliciously and I really dont fancy this happening again. The "best" (and completely unrelated) I've found on how to undo this, let alone prevent it from happening again is pressing esc or f11 because of course everything these days has to drown in AI slop :/

Hi.

I'm having trouble with https://support.mozilla.org/en-US/kb/linux-security-warning?as=u&utm_source=inproduct#firefox:linux:fx140.

It assumes the installation is at "/home/<USER>/bin/firefox/{firefox,firefox-bin,updater}" but mine is "/home/<USER>/.local/share/torbrowser/tbb/x86_64/tor-browser/Browser/firefox.real".

How exactly do I edit the line?

(Latest Ubuntu. I also have Librewolf and Firefox, but didn't see the warning as on Tor.)

How do I turn off all warning and redirects for unsecured web sites. I am an embedded developer and 90% of what I do is work on designs that can be configured via a localhost web page. I'm tired of the warnings and the constant attempt to turn http into https.

Hi all the people,

I was just surprised to see this in an Apache HTTP log: "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Firefox/58.0.1"

This bugs me. My first guess would be that a Webkit based Firefox could not be qualified as really Firefox. Although that, I could imagine a Firefox for iOS or MacOS based on Webkit, may be, but it says it is on Windows, which makes less sense.

I suspect this is a user agent string spoofing, but I just need to be sure (I try to get ride of far too invasive bots, while I’m afraid to disrupt browsing from legitimate web users).

With thanks and my apologizes for such a question which may looks obvious or strange to people who know for sure.

After all of those years, am I witnessing now that FF literally failing?

How could it become mysterious by that it lets user's location leaked to github even though: - third-party HiFi company VPN is active and in OpenVPN UDP/TCP, Wireguard, IPv6 On/Off, etc... - No bookmark to corresponding website - Cache and website data were so-called cleaned, - Other browsers don't give that symptom, only FF - No related plugin, out of only 3

it's impossible to find out how it lends to the language and region query of this website every time after cleaning. Is FF getting closed app?

Is that a no-way-to-explain effect of language models' evolution is exponentially higher in every 4 months after two years?

There must be a way to turn off this popup off. This is REALLY annoying when it covers a password box and to remove it i must click outside it and I lose focus on the password box. If you must put he box there then at least leave the first part of the password box clear so I cab click on it and not have to click again to get the focus back.

Some users are abandoning Firefox because of the difficulty of protecting against Firefox fingerprinting. Therefore, I strongly recommend adding an option in the settings that allows the digital fingerprints to be made random, or at least, if it is difficult, to make the fingerprints indistinguishable. This will help improve Firefox’s reputation and the privacy of its users. Love you all 3:

Some extensions I use have been updated and now ask permission to "Access your data for all websites." What is the scope of this access? Can an extension which facilitates video downloads see my bank password? Can it access data for sites in a different Firefox container? Can it access sites which I use in a different browser? Can it access data for sites which, on my system, are only available to a different user? Thanks for any clarification. [I am running Firefox 149.0 under Kubuntu 24.04]

I am using version 143 for Linux and it is suppose to have improved fingerprinting protection. But when I go to https://coveryourtracks.eff.org i still see a result that says "your browser has a unique fingerprint"

Is there a parameter I should be enabling ?

This happens occasionally for many months. It is still happening on v147.0.1. I start the computer, open Firefox, and the browser loads previously viewed pages, including my Gmail account. The Gmail page has me already logged in, and I DID NOT provide my password! This has to be a big security risk. If some one were to use my computer, or it was stolen, they would have complete access to my Gmail and all Google properties!

New to Mozilla! Just "your opinion." on average, and I know this can be a relevant question, how should I approach banking transactions on this Browser? is it among the saver ones.
