Firefox Support Forum

Firefox fails to recognize my GPU's and uses my integrated GPU rather than my dedicated GPU. I'm using Kali Linux (usually alike Debian Sid on repository grounds), I'm invoking it using DRI_PRIME=1 environment variable because that's where my Radeon RX560 is but firefox opens with this warning on terminal:

[GFX1-]: More than 1 GPU from same vendor detected via PCI, cannot deduce device.

I've even tried nightly but it doesn't recognize the dedicated GPU either, my other GPU is a Radeon Vega 8. All other other programs on the system and even Chrome recognize my RX560. Using DRI_PRIME=4 (that's where my Vega 8 is located) launches the browser with the same warning and again uses the integrated GPU, I know which one is using because radeontop shows memory usage only on the integrated GPU.

I don't know if this isn't the right place to post this, if you know a better place please tell me. Thank you in advance.

I have an Ubuntu desktop and I am trying to switch my browsing from Chrome to Firefox but cannot load the website "https://messages.google.com". This is actually a NEW install of Ubuntu Desktop 20.0.4 which had Firefox 86.0.1 64-bit pre-installed.

I have been using the Google Messages app via the computer successfully for YEARS on current versions of Chrome on Ubuntu (and it still works today). I have cleared Firefox cache and all data multiple times. I have restarted the browser multiple times. I have tried to hit the website in standard and private mode. No luck.

If I hit https://messages.google.com/ I get the pretty page with icons then click "messages for web" link in the right corner which redirects me to "https://messages.google.com/web/authentication" and I get a blank white page that never changes. Ever. With Chrome the next thing I would see is a QR code to scan with the phone app ... then it works. Nothing with Firefox.

The page Give feedback landing page says: ‘Please check back soon’. What does ‘soon’ exactly mean?

When I start typing in the Address Bar I get a few suggestions: first there are my bookmarks (one of which fills the address), then there are results from my search engine. I like that. But let's say, for example, none of my bookmarks start with the letter 'z'. What I want to see when I type 'z' is the results from my search engine, like random popular words or sentences. Instead I receive some mainstream site that I never use, 'zooniverse dot org', followed by '-- Visit'. Is it possible to turn that off?

Why can a stupid failing script on a web-page, or even intentionally so programmed script disable the copy (and sometimes paste) functionality?

How can this be disabled/fixed?

One highlights a text (any text) on some web sites, Edit menu allows Copy, context menu allows Copy, one hits Copy, nothing happens. It's not even a page where someone wanted to "copy protect" some information.

Copy and Paste should work just as advertised since those were invented, how hard can it be to get that right? Even stupid Notepad never fails at it. And no, I don't care what the idiot who programmed a page though would be/should be best for me, I want Copy to be copy, Paste to be paste. This used to work in "original" Firefoxes even when page developers wanted to make it not work.

And yes, while on a given page Copy fails miserably, at the same time in other pages it works.

Hi all, I have an Apache site on Kubuntu 20.04 with a certificate signed by my private CA. I've added the root CA ceritificate in Firefox and in Chromium.

Firefox throws a SEC_ERROR_BAD_SIGNATURE error

Chromium accept the certificate as valid

What can I do?

Notes: the site url is "https://hdev.h.net" (with an internal IP address inside my lab)

Attached there are:

- the authority settings page
- the certification authority certificate as seen by Firefox
- the site certificate

Firefox version 82.0 Ubuntu Chromium version 86.0.4240.11

'Hi firefox community i ve been using firefox since it's launch day and one of its feature i love is the recent highlights, it's make navigation easier for me, the last couple of days i updated firefox to the latest version and noticed that recent highlights disappear. my question is, is this happened to every one or just for me? i've also tried to check other distro's (pop os - Manjaro) and the problem is the same as in my Ubuntu machine

Firefox browser 52 is the version on my computer and was bundled with my version of the Linux operating system. I have not been able to upgrade. I was told that I might have to remove the browser and then install a later version, but Firefox, when bundled with certain versions of Linux, will not be completely removed, and then a new version of Firefox is impossible to install. I and others have experienced this in the past, so I need to simply upgrade the browser I have to at least version 57. Please give me instructions that will work. Thank you.

When I go to https://www.sz-shop.de/ostern, FF tells me that there is a risk

"Warnung: Mögliches Sicherheitsrisiko erkannt ... Am wahrscheinlichsten wird das Problem durch die Website verursacht und Sie können nichts dagegen tun. Sie können den Website-Administrator über das Problem benachrichtigen."

That is what I did. I called that shop and told about that warning. The lady on the phone also went to the address, but she did NOT see that warning. She confirmed that her PC was OUTSIDE of sz-shop.de like mine.

So the problem is a potentially wrong warning? Or how can we explain that I see a warning and other people do not see it?

Hello Mozilla community!

yesterday I installed a program which installed adware (I overlooked a little checkbox). It also changed a couple of settings in my standard browser (Firefox) like the search engine etc. It also changed the homepage. I always had the homepage pointing to my YouTube feed. I changed it back to it using the about:preferences#home method. Under "Homepage and new windows" I set the homepage to my custom URL and the home button works perfectly fine. Yet when I open a new window (with ctrl+n, not a new tab!) it also displays my home page (YouTube). It has never done that before and I cannot find anything in the settings to change that. I tried looking in about:config with browser.newtab but didn't find anything that seemed related to my problem. A couple of weeks ago I tried Firefox Nightly and I started it up and the homepage worked fine AND it didn't display it in a new window. It only did this after it synchronized the data with my Firefox account. Now my question is: How can I remove the the Homepage from a new window (and replace it with an empty page or the Firefox Home)? Thanks in advance for your suggestions!

Kindly Jay

p.s. I attached the Troubleshooting Information and I'm using Linux

My online banking access used to work perfectly but does not worked any more. In the login process, it simply does not go any further without any error message. The laptop is the same as before. The only thing that has changed are updates to Firefox version 87.0 and Ubuntu version 18.04.5 LTS. On another laptop, the bank access still worked perfectly. I have tried to switch off all restrictions in the Firefox settings and to deactivate all add-ons, unfortunately without success. The bank couldn't solve the problem either, they just said it was probably due to the browser settings. Do you have any ideas? Thank you! Wolfgang

After installing the Native MathML extension (to get MathML typeset equations on the Wikipedia, as suggested on mediawiki.org), all equations set by MathJax/MathML turned to using STIX instead of Latin Modern. I'd like them to stick to Latin Modern instead.

The only possibly related setting I've found is `font.name-list.serif.x-math` in about:config, whose value is `Latin Modern Math, STIX Two Math, […]`. I tried to manually change the font family specification of some text to see if Firefox could use Latin Modern Math to begin with, but apparently it can't (see first screenshot attached), while it loads STIX allright (second screenshot). Latin Modern is not the first locally installed typeface I haven't been able to use, but it's the first one I have really tried to (I don't remember which one the other typeface was).

My Latin Modern font comes from TeX Live 2019 installed using the TUG installer, not Fedora's package manager. `fc-list | grep -i "latin modern math"` returns `/usr/local/texlive/2019/texmf-dist/fonts/opentype/public/lm-math/latinmodern-math.otf: Latin Modern Math:style=Regular`. I'm running Firefox 87 on Fedora 33.

My computer was updated with the latest linux and the latest firefox browser. I want to create folders in my bookmarks. All the help answers say to go to Bookmarks and click on 'Menu'. That does not come up as an option. All I get is: Show all bookmarks; bookmark this page; bookmarks toolbar; other bookmarks. I can't find anything similar in tools, edit, or file. I also don't get 'Edit Bookmarks' like was in the last edition I had.

While browsing https://www.mathrubhumi.com/ site, a warning will come "A webpage is slowing down your browser, what would do like to do, stop it or wait" Then system monitor shows a web content is consuming around 4.5 GB and firefox itself stopped the webpage. If the memory usage is higher the system will hang.

As the subject stated, I'm desiring to achieve the result that I can run some webpage with the window containing only the page itself (without toolbar, address bar, etc.). The --kiosk command line option is almost what I need but it will enter the fullscreen mode whatsoever. For instance, chromium has the --app option which is exactly what I want it to be. Thanks in advance!

Hi! I am trying to move FF profile with saved data such as extensions (anti-captha). Tried just copy a profile folder but not successful. It is not contains folder "extensions". Please help!

The firefox extensions expect to find the respective javascript files inside their definition folder containing manifest files and related resources Is it possible to access and share the same user library (js file) between all extensions without having to copy it back to all the extension folders when it is modified? Thanks for any suggestions you have
