Firefox Support Forum

A long time ago, I saw a list of open tabs in all windows, not just in one window, as it is now. (By the way, Google has added such a feature to Chrome. Clicking on the arrow allows us to see any open tab and navigate to it.) I am currently using Tab Manager to search for a tab. But the tab manager is not the best option because it is too slow to open and requires too many resources. Can I restore the old behavior to see tabs in all windows?

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?

In the past I was able to set the setting ``` browser.urlbar.clickSelectsAll browser.urlbar.doubleClickSelectsAll ``` to disable that a single click into the address bar selects the whole url. Is it possible to achieve this with the new QuantumBar somehow?

I was messing around with Privacy & Security settings. Under Cookies & Site Data, I checked Delete Cookies & Site Data when Firefox closes. I've decided I don't like it and want to uncheck it. But now it's greyed out and I can't find any way to change it back. It says I'm in permanent private browsing mode. There MUST be a way to change this back to how it was! What is it???

I am unable to connect to the following URL https://lakmshaegov01.msha.gov/UserManagement/ChangePassword.aspx. All other browsers seem to work.

I ran an SSL Labs test and it confirms that all tested versions of Firefox fail. I would like to know if anyone can spot something that might allow me to connect by temporarily relaxing the security checks in Firefox for this site.

I am running Firefox 76.0.1 on GalliumOS 3.1 on a Lenovo N21. For some reason, my add ons don't show up or work, even though they are installed. Firefox works great on my other two machines, and used to work great on this one. Thank you Jason Stone.

When I try to watch a video on WSHH, I get this error VIDEOJS: ERROR: (CODE:4 MEDIA_ERR_SRC_NOT_SUPPORTED) No compatible source was found for this media. I have DuckDuckGo Privacy Essencials installed, and I also have uBlock Origin installed. I disable both extensions but I still see the same error. I'm on Ubuntu 20.04 LTS, and my Firefox version is 77.0.1 (64-bit) canonical - 1.0

I attach the console log.

How do I disable the blue flash when a tab finishes loading? I'd like to suggest an option in a future release that disables all these things.

I find it a real distraction, and it's really putting me off using firefox as a broswer. I really don't think this sort of eye candy is needed in order to browse the internet.

In my browser whenever I am opening non secure sites that are only like http://example.com it redirects to https://example.com and display the error. "Warning: Potential Security Risk Ahead" error. I could not know how to fix this error. This is happening all of a sudden. I could not find a way to fix this error.

Hi today I opened my linux installation and Firefox is only getting a window with the text:

             <toolbarbutton id="UITourTooltipClose" class="close-icon"
</pre>
I tried to run from the console with the  --MOZ_LOG_FILE flag and the generated file has absolutely no text in it.
Some information about my system:
kernel: Linux localhost.localdomain 5.7.7-1-default #1 SMP Wed Jul 1 19:03:27 UTC 2020 (cba119b) x86_64 x86_64 x86_64 GNU/Linux
OS: openSUSE 20200715
DE: KDE 5.72.0 / Plasma 5.19.3
Version: 78.0.2-1.1 (according to zypper info MozillaFirefox command)

I am building a website and, for the last couple of days, when I make changes to the CSS file they are no longer being picked up by the browser by which I mean they aren't displayed in the web page nor in the developer tools inspector.

They are visible in Chromium browser and dev tools.

I have cleared the cache and refreshed the page to no avail. It is only when I restart the browser that the new style rules take effect in the browser and show up in the dev tools.

hello, i have a Raspberry Pi 4 with 4GB and Raspberry Pi OS installed. (2020-05-27-raspios-buster-armhf.zip)

when i use the stock Firefox ESR (installed via sudo apt install firefox-esr) and watch videos (e.g. on Youtube, Vimeo, ...), Firefox does crash some times. according about:crashes, i already have submitted about 60 crash reports.

but watching the reports one thing is missing. when i open firefox from the console i can see some output, that is not appearing in the reports.

... firefox-esr: /build/firefox-esr-RgOFaD/firefox-esr-68.11.0esr/media/libcubeb/src/cubeb_alsa.c:1255: alsa_stream_get_position: Assertion `delay >= 0' failed. ExceptionHandler::GenerateDump cloned child 3366 ExceptionHandler::SendContinueSignalToChild sent continue signal to child ExceptionHandler::WaitForContinueSignal waiting for continue signal... Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Exiting due to channel error. Failed to open curl lib from binary, use libcurl.so instead Firefox ESR crashes when playing videos on Raspberry Pi OS (Debian)

during watching videos in firefox there is more different output to see that seems to be harmless. but always and only this line is printed to console, just befor Firefox crashes: firefox-esr: /build/firefox-esr-RgOFaD/firefox-esr-68.11.0esr/media/libcubeb/src/cubeb_alsa.c:1255: alsa_stream_get_position: Assertion `delay >= 0' failed. so i assume this is the main reason, why Firefox crashes on my system.

any idea how i can get these issue fixed? at the moment when i want to watch videos reliable i am be forces to use the external VLC Player by copy the url to VLC - at least for Youtube videos. but i want to watch videos from other web pages as well and i prefer to watch videos in firefox directly.

When I use Firefox on the external monitor, I set the zoom level to 150%. When I leave home a take my laptop with me, I set the zoom level to 100% to use with a smaller screen.

I want to automate setting the zoom level.

Is there a way to programmatically set the zoom level from a script? Does Firefox expose such an API / command-line tool?

Thanks!

I am facing the problem to open the sites. When I used the network, it show the following error:

Hmm. We’re having trouble finding that site.

We can’t connect to the server at www.google.com.

If that address is correct, here are three other things you can try:

   Try again later.
   Check your network connection.
   If you are connected but behind a firewall, check that Firefox has permission to access the Web.

Please let me know your suggestion and comments.

Chinese Characters displays strange (some characters are extremely large) on Manjaro, and it will make Edge and Firefox on Windows display strange too.

Installed "Firefox Color" from Mozilla, selected a predefined theme, made some changes and saved it for backup. After refreshing Firefox, I tried opening this .xpi file but Firefox rejects it as being corrupt. I tried this process several times. What am I doing wrong?

I've been an avid user of Firefox Monitor for the past few months, but recently over the last few days when I go to https://monitor.firefox.com/user/dashboard and log in, I've been struggling to find the button that allows me to add new email addresses. I've searched the support article for Monitor for this information, but to no avail: https://support.mozilla.org/en-US/kb/firefox-monitor. So I was wondering if you could point me in the right direction?

A new feature of firefox 81 says the pdf viewer can be used to fill out fillable pdf forms now. But when clicking on a field on a pdf form, I get the message "This document contains forms. The filling of form fields is not supported". Is there something I need to enable?

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:

Yes, I am located in the US.
