I just reinstalled my operative system, and with that my Firefox settings got reset. I know there is an entry in about:config to prevent ads from opening new tabs and pop ups without authorization, even from legit websites like the login pop-up windows when doing a sign in in Google, in those cases to allow the windows it's needed to click on the lock icon next to the URL bar and allow it from there. The problem is that I don't remember the name of that setting and I have spend an hour looking for it on Google.

Hello,

I am running Firefox v101.0.1 (64-bit) on Linux (Pop!_OS, installed as a flatpak). I am using the default system theme in dark mode, though switching to the Firefox dark theme or other themes does not change anything. When I allow the Menu Bar (File, Edit, View, etc.) to be present, the browser tabs on the next line are aligned correctly, going all of the way to the left. When I uncheck the Menu Bar, however, a gap appears to the left of the tabs. I have not seen this behavior on Firefox in other environments (Debian, RHEL, Windows), and I'm wondering if there's a way I can remove that gap. I have attached screenshots showing how the tabs are aligned with and without the Menu Bar.

Thanks so much!

Hi, I'm using version 101.0.1 (64 bit) for Ubuntu 22.04. When I open a link of a pdf file, the file is displayed in the built-in viewer, since I chose "Open in Firefox" in my settings. But then if I click the download icon nothing happens. If I click the print icon and choose "print to pdf" in the popup, then clicking on "save" does nothing and I have to click "cancel" to dismiss the popup.

Actually there is no way to save a pdf file but setting PDF app to "Ask always" and then open it with "System handler", but then the file is saved into the default download folder, even though I selected the checkbox "Always ask me where to save files" in my settings.

EDIT: the issue was solved by installing the following packages, as shown in this question :

Hi, I hope someone can help me. I am an author and sell my book through KDP Amazon. Firefox is my default browser but will not let me log in to KDP. No problem with other websites including Amazon.com When I open the KDP log in page it accepts my email address but the password button has a row of asterix right across the window. I cannot delete whatever is in there or change the password via the forgotten password route. Thus to sign in to KDP I have to use an alternate browser. With both Opera and Chrome I can sign in with no problems. I have added a screenshot of the KDP log in which illustrates the problem. Grateful for any solution to this irritation. Thanks, Paul

An automatic update of Firefox which resulted in a "quit/create new profile" choice has removed all my bookmarks

Of the four profiles stored in "about:profile" three are identical (ie. have only the default bookmarks stored) and one, generates a "quit/create new profile" message.

The "bookmarksbackup" folder (in /home/user/.Mozilla/Firefox/zs1jki8t.default) is empty.

The "import/backup" option (in Manage Bookmarks) offers nothing to choose. There is no 'list of dated automatic backups.'

Firefox did not create an "Old Firefox Data" folder on the desktop.

Browser privacy "strict". "Never remember history" was selected.

Hi, Just installed Ubuntu on a new laptop, with Firefox. No add ons.

Have changed my homepage to www.duckduckgo. Have changed my default search engine to duckduckgo. In about:config my browser.startup.homepage says www.duckduckgo.

Have also changed browser.startup.homepage_override.buildID to www.duckduckgo.com and browser.startup.homepage_override.mstone to www.duckduckgo.com

But STILL, every time I start Firefox, I'm taken to google.com. Please cn someone tell me how to stop google coming up when I start Firefox.

Thanks, Ivan

Hello. For the past few days, I am unable to access the content of some websites. For example, Reddit seem to load but the page remains blank. This happens on other websites, where I am unable to login although the page displays correctly (an error message appears on one of them: "Please check the consistency of your URL").

This is quite annoying, especially because I cannot find anything related on the web. I use Firefox on POP OS 22.04.

Thanks. Cheers.

Hello,

Since recently the bookmark dialog has changed its behaviour, and to worse from my perspective. If I don't do anything for about three seconds, the dialog closes and the bookmark is saved to a place where I most likely don't want it to be saved. Is there a way to get rid of the three second time limit? Thanks!

It's not necessary to read further to answer my question. Bellow I'm going to give some criticism and express frustration about this new feature (or is it a bug?). The criticism is not directed towards the nice people here who give support to users who have problems.

I understand that developers get new ideas and want to put them into practice, but if you change an often used behaviour like this, I don't think it's user friendly to just change the behaviour without asking the user if he want's that behaviour. Personally I don't see how the automatically disappearing dialog helps me (it's very easy to click Esc if I change my mind about bookmarking a page), but I keep experiencing how it makes my browsing experience worse, as I often pause for a moment for example to think what name I'm going to give for the bookmark, or where am I going to place it.

In practice this change has wasted at least an hour of my time (to find an explanation and (in vain) a solution to fix the behaviour), made me annoyed, and based on the comments here and other places, made quite a few other people annoyed too.

Please, when you change the behaviour of Firefox in the future, before changing the behaviour for an individual user, ask him first if he even wants the change. For example show him a dialog where he is told that "we have this new feature where your familiar dialog keeps disappearing every three seconds for no reason so that you get the pleasure of invoking it again...and again...and again. If you want to have that feature, check the box on the left".

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?

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.

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.

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?
