Firefox Support Forum

Hello, I'm using Firefox 100.0.2 (OS: Ubuntu 20.04). It is not possible to manage if/when firefox updates are installed. In the options-section, there are some information about the current version number, however no chance to configure anything update-related. Updates just happens automatically and interrupt current sessions, leading to spontaneous (and surprising) dysfunction of the opened browser. That's very annoying in case of video conferencing, for example, because it is not possible to open any new tab or windows, always the note there "you have to restart firefox now" - in practice, just like a crashing error. And, the suggested restart does not re-open the current opened tabs/URLs!

Furthermore, within some updates, my language settings get lost, so it turns to English language automatically and I always must add my language packet manually again and again. Thats really annoying and maybe completely disruptive for people that are not able to read in English!

Is there any chance to come over this? Otherwise I guess I must leave using firefox as browser, however this would be not the aim I actually follow. Thx!

FF 100.0.2 Ubuntu 22.04 LTS

I have deleted my bookmarks with the Bookmark manager, but where are they now? I cannot find them in /trash and all of the *bookmark* files on my laptop are miniscule (like 127 bytes.) The json files are no better, when I imported previous bookmark files they were empty.

Whenever I use web-applications that use WebGL or anything similar, they are always distorted. And yes, I have tried disabling Performance Settings, but that only slightly helped.

I haven't used my microphone in Firefox in years. I tried today, logged into Google Voice, which tells me it can't access the microphone. I set permissions in Firefox's settings. I turned up all the mic settings in alsamixer. I tried https://mdn.github.io/web-dictaphone/ , recommended in another thread here, and it doesn't record either. I can use the microphone outside X, with sox's rec. I also can't record a new greeting in Google Voice.

Firefox 100.0.2 , Linux, Slackware 64-bit, all packages updated this morning.

I cannot access Mozilla via Firefox - issue arose when trying to access add-ons yesterday (25 Jan 2020). Firefox displays the following: "Secure Connection Failed

An error occurred during a connection to addons.mozilla.org. PR_END_OF_FILE_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the web site owners to inform them of this problem."

In order to post this, I have had to access the site via Chromium, which also noted a secure connection error. I have used a VPN add-on to secure the connection and access the site.

I assume this is an issue on the Mozilla server with an expired certificate?

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?

https://support.mozilla.org/en-US/kb/containers seems to suggests that it's possible to hide all tabs in certain containers, but does not explain how to do that.

"Hide and Show: Assume you use your browser for both Work and Personal tasks. When you come home at the end of the day, you don’t want to be thinking about “Work” anymore, but your browser is full of Work tabs. You can “Hide” your Work tabs and proceed with your Personal tasks. Then the next day, when you are back at work, you can “Hide” your Personal tabs and “Show” your Work tabs."

On an aside, I'm also getting pretty confused between collections (mobile), containers (desktop), sessions, tab groups, etc... they all seem to have overlapping but different functionality.

Hi there, I run FF 73 on Lubuntu, and since the upgrade chrome://browser/content/places/places.xul is no longer found. I use it as a handy bookmarks and downloads manager within a tab. Error message:

"Firefox can't find the file at jar:file:///usr/lib/firefox/browser/omni.ja!/chrome/browser/content/browser/places/places.xul. "

I realize that this question is similar to https://support.mozilla.org/en-US/questions/1223548#answer-1127393 but it doesn't solve my issue. In fact the URI's listed also don't work I have found:

   chrome://browser/content/places/places.xul
   chrome://browser/content/places/bookmarksSidebar.xul
   chrome://browser/content/places/historySidebar.xul 

Please advise. Thanks for your help!

I installed Nightly hoping to be able to play videos. It worked for a while but has recently stopped. I have a screen shot with the error and the version of nightly. I am running Fedora 64 bit with the updates installed.

Firefox 75.0 has just been released. Address bar has been ruined with dynamic size and lines with increased height. For some unknown reason Mozilla developers think that taking away more vertical space will help their browser have "Focused, clean search experience that's optimized for smaller laptop screens" as they state in the release notes. Outrageous.

Now tell me how to go back to the old behavior.

I want a full horizontal length search result widget as it was before.

I DO NOT want an ENLARGED address bar while searching. Simply annoying that it changes its size and looks like popping out from the upper top toolbar every damn time I type something into it.

I want the ORIGINAL LINE HEIGHT of search results in the expanded address bar.

I want an address bar that doesn't expand when focused with Alt+D, like the old one.

I haven't found an about:config option to restore old behavior. However, a userChrome.css workaround is still good for me.

Is the a way to remove this new focused address bar? I want to be normal like in FireFox 74 the new style is so annoying.

https://support.mozilla.org/en-US/kb/search-firefox-address-bar

As of Firefox 75, the address bar plumps out in an "enlarged" state. This is a new feature of Firefox 75, announced here: https://blog.mozilla.org/blog/2020/04/07/latest-firefox-updates-address-bar-making-search-easier-than-ever/

I'm wondering: how can I revert this back to how it was? I don't want it to plump out since it partly covers up the surrounding UI elements. I have a muscle memory for sometimes minimizing this bar with Escape, then clicking one of my bookmarks or one of the UI elements. I haven't had an issue seeing the address bar before, so this new feature is a detriment to me.

Thank you

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 can't open a Spotify URI from Firefox But I can open it from command line using the --uri option. As in, this works fine from the terminal:

spotify --uri="spotify:artist:6OqhFYFJDnBBHas02HopPT"

and whatever Firefox is doing just launches Spotify without navigating to the thing indicated by the URI

Is there, perchance, a simple file edit I can do that will fix this for me?

So the problem is that Firefox doesn't play any HTML5 content. Weirdly except for Youtube. Youtube works just fine. But every other Website shows errors. Even songsterr.com. I'm using latest Firefox 76.0.1 on a recent Ubuntu 20. 04 LTS installation. Usual troubleshooting like updates doesnt work because "sudo apt-get upgrade" doesn't find any updates. I tried the same websites in the latest version of Chromium and they work perfectly fine. I couldn't find a mistake in the firefox settings or something so I'm confused. Disabling Plugins didn't change anything and turning of tracking protection didn't either. What is the Problem here and how can I solve it?

For some reason my firefox history is always incomplete. E.g. when I search for something on duckduckgo and then visit stackoverflow, it often doesn't add the visited page (in this case stackoverflow) to the history.

iam currently using acer nitro 515-52 with ubuntu 18.04 as my base os and whenever i try to access the live videos on you tube the following error occurs "our browser does not currently recognize any of the video formats available. Click here to visit our frequently asked questions about HTML5 video". I have only browsec plugin installed on my extensions. I even tried to reinstal my firefox but the same error occurs. kindly suggest me an article so that i can overcome this issue.

I am trying to add my own background to the home page but cannot find any way to do it. There must be an option for something so simple somewhere, but I cannot find it. I do not want to install an add-on for this as I am not comfortable handing out my personal info to some random guy or group to accomplish something so simple. Thanks.
