After an update today, private browsing windows now are a different color than the other windows. I don't want them to be a different color. How do I change them back to the same as the other windows?

Also, how do I remove the extra text label next to the private mode icon, and just generally put things back to the way they used to look?

When I click ctrl+q by mistake, the browser window with all its tabs is closed immediately, with no warning. This has already made me lose data. is there a way to disable this keyboard shortcut?

I just updated Firefox to version 81.0 in Linux, Windows and Mac, but the credit card autofill option is still missing from the Preferences menu.

I followed the instructions from here:

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

Recently, I had to change my username at my bank's website because somebody was trying a brute force attack on my password. Now, the site still shows my old username, although I've gone to my Saved Logons in Preference and removed all logons for that site except for the correct one. I have to delete the old username from the typing box every time I log in there, after which I can select the correct (and only) saved username/password.

Hey there,

I have the following issue with Firefox, is this maybe something I should report to the Ubuntu support or directly to Bugzilla?

Steps to reproduce: ---

1. Open Firefox
2. Go to a page that contains an embedded video that is not playing automatically, e.g. https://www.rottentomatoes.com/m/sound_of_metal
3. Do not play the video

Environment --- User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:83.0) Gecko/20100101 Firefox/83.0 Firefox version: 83.0 (64-bit) pulseaudio version: 13.99.2 OS: Ubuntu 20.10 64-bit Gnome version: 3.38.1 Windowing system: Wayland CPU: Intel® Core™ i7-8565U CPU @ 1.80GHz × 8 RAM: 15,5 GiB GPU: Mesa Intel® UHD Graphics 620 (WHL GT2)

Actual results --- pulseaudio process is spawned and rapidly becomes the most CPU consuming process on my machine (especially after a few seconds, when the Web Content ones start to cool down). Even though no sound is actually played! When switching to another tab with no embedded video, pulseaudio keeps overloading the CPU. This only stops after closing Firefox.

Expected results --- I'm not sure this is what should be expected, but I'll give it a shot:

• pulseaudio process should only be spawned when actually playing a media that requires audio
• pulseaudio should not be the #1 CPU consuming process
• pulseaudio process should at the very least not massively use CPU when no sound is playing

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

in about:config page the options: browser.tabs.warnOnClose (true - default) browser.tabs.warnOnCloseOtherTabs (true - default) browser.sessionstore.warnOnQuit (false - default) browser.warnOnQuit true (true - default)

But when i do Ctrl+q accidentally, it closes the only Firefox window i have. This window has many tabs open. Yes it restore next time, but i want FF to ask me before closing it.

FF 84.0.1 Arch Linux

When Firefox asks if I want to download an update and I agree, soon after that but not right away it stops working - on every new page it says "We need to restart to finish updating" <- This last bit is VERY annoying. Is there a way to keep FF working in such situation? I usually have 3 FF profiles running, about 10-20 tabs each and when it suddenly does this - I can restart them all but when it is suitable for me.

The only solution I can see so far is disabling updates via group policies (which is not well documented, where do i put this policies.json on Fedora? need to google that).

Any other ways to keep updates and FF running until I decide when to restart? Thanks.

Hello dear community,

I recently switched to a dual boot system and got Ubuntu 20.04.1. If I want to watch Netflix for example I cannot because of DRM settings (at least the pop-up of Firefox says so). Other video and audio content is working fine so far. The guidelines on what to do to solve the problem like this

https://support.mozilla.org/en-US/kb/enable-drm?as=u&utm_source=inproduct

won't work unfortunately. Does someone have any other idea what to possibly do?

Thanks a lot for your help! -Jo

I here refer to my thread https://support.mozilla.org/en-US/questions/1285212 in which the problem were not even answered by any of your tech people, but archived - why?

I find it really bad, if i post a bug and you just archive without even try to fix the problem! It makes me extremely angry! Bad behavior!

Please stop that and re-open the case.

Jan Ps. same system (Lenovo Thinkpad X300 with Xubuntu 16.04LTS 64bit (account A) )now running Firefox 85.0.1 64bit can now print, I can't find any mentioning in release notes to how previous version 75.0 and now this one is different and why this one now can print.

It would be nice to get this solved, since other people here has had this one too and it seems to jump between versions and OS(linux an windows).

When I download a file and click on the downloads button to bring up the Downloads menu, I often just want to open the Linux Mint file manager in the right folder so I can move the file to a more appropriate place.

In the menu, there's the little button to the right of the listed downloaded file with "Open containing folder", but if I click on that, FF opens the downloaded file, not the file manager.

Obviously this wasn't always like this, but I don't recall doing anything that might have caused the issue. How can I set FF back to the default action of opening the Linux Mint file manager?

Thanks!

I was following this reddit thread on how to remove the "your camera and microphone are being shared" popup, but it's having no affect.

I have set `toolkit.legacyUserProfileCustomizations.stylesheets` to true.

Here's the full contents of the userChrome.css file: ```

Hi guys i'm new in the forum so i have no idea if anybody else allready had my problem,i've tried to fix it myself but i cant seem to get it done. Yesterday i had a problem with my OS linux,and i had to reinstall the system,while i was pretty sure i had all bookmarks saved in an external HD i went straight to a quick format and reinstall of the OS,after installed all the due system update.

The Problem:

While i was importing the bookmarks.html i stored in external HD i noticed that nothing was being added in the bookmarks of Firefox,so i tried few times just in case i was doing something wrong but still nothing was being added in the bookmarks,so i tried to import the bookmarks on Tor Browser and the same thing happened nothing was imported. So it came to my mind that the .html file could've been damaged. Now i tried many ways to open the file either in command line or text editor i even tried using libreoffice,in the case of text editor,command line such gedit,pico,nano it loaded the file but it was heavily encrypted,in the case of libreoffice shortly after i tried to open the file popped up a message telling me that the file was corrupted and libreoffice couldn't read it and stopped.

I need a solution to either fix the .html file or decrypt it so i can recover the web addresses inside and it would be very bad for me since my bookmarks.html is 3.3Mb large with ALOT of bookmarks inside.

Can anybody tell me how to?

Thank you in advance for any help or suggestion that may help me to retrieve my bookmarks. Ludo.

P.S. OS Linux BackBox 7 up to date along with it latest version of Firefox that update server provides me.

Firefox can't load any page, including about:config and about:preferences. about:support is working. All menus and surrounding UI is working too, but, for example, if I try to open Preferences page from menu - it will not open, even new tab isn't created.

If I start firefox with MOZ_DISABLE_CONTENT_SANDBOX=1 all works fine. Problem appeared after I accidentally used all of my laptop RAM with other app. Firefox didn't crashed, but after reopening this issue is began appearing.

I use Linux Mint 20, and apt-upgraded all packages (including firefox) right after this issue first appeared. I tried to: - restart browser (didn't work) - restart laptop (didn't work) - use different profile (didn't work) - use browser safe mode (didn't work) - clear caches (didn't work) - disable all extensions (didn't work) - use different versions: 75.0, 87.0, 82.0, freshly-compiled by myself (didn't work) - refreshing firefox (didn't work) - run firefox with MOZ_DISABLE_CONTENT_SANDBOX=1 (worked, but it's obviously unsafe and don't fix the root problem)

I found some issues and bugs that looks pretty similar to mine: https://support.mozilla.org/en-US/questions/1245935 https://support.mozilla.org/en-US/questions/1235332 https://support.mozilla.org/en-US/questions/1279656 https://bugzilla.mozilla.org/show_bug.cgi?id=1433065

Also, after closing firefox, it stays running in processes, and I can't open new window for 30 seconds or more after closing old window.

I think it's bug and problem is somewhere in firefox sources. Do you have any ideas, how can I fix this?

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.

Dear Mozilla Community,

I would like to suggest you to make built in adblocker in Firefox. For example Opera have this feature so we don't need install any extension. People from Mozilla read subjects in support.mozilla.org? If not where I can send my suggestion?

P.S. I wanted to install Adblock Plus extension but I am afraid about safety so better option is to make built in adblocker to protect from malware. I think that this can be direction in good way.

Yours faithfully, Piotr

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?
