Firefox Community Forum

I have lost my tabs after the recent update. They used to show all tab groups in toolbar icon as mentioned here (https://support.mozilla.org/en-US/kb/tab-groups) in manage tabs section. Only the groups that were open are retained, the groups which were closed are lost. They contained important tabs which I haven't bookmarked. I didn't see any policy of removal of inactive tab groups after certain time, any help would be really appreciated. I use the desktop app on Linux.

I updated firefox through apt, and since then, have not been able to log into twitch I am on ubuntu 24

apt list --installed | grep firefox firefox/mozilla,now 144.0.2~build1 amd64 [installed]

Attempting to log in returns the generic "Your browser is not currently supported"

Since the update to 142, on pretty much every site it keeps jumping back to the top of the page. Happens on a lot of sites. For some reason, if I select some text at the top of the page it seems to stop this. A lot of people may not have discovered this. Mozilla just needs to fix it. I am using Ubuntu 24.04. Been using Firefox for many years. Never seen this before.

For the last two years the issues with video stutter have been worse and worse for me. I don't know if it is because of a different codec the video is using, but if it was I would expect the fans to ramp up from trying to decode it. Instead, my laptop stays always silent, but the video laggs like crazy when I want to play it at native 1440p.

I cannot view or change the video codec, since the current issue happens on a platform (herohero.com) other than youtube.

For some reason my install of FireFox on Linux refuses to hide the picture-in-picture button in the address bar on video sites.

See included images; all relevant settings are disabled.

After upgrading my 128 esr to 140 esr, some sites stopped opening. In regular versions, it has not opened for a long time. There are many such sites, for example, qwen3.app or temp-mail.io. It thinks for a long time and finally a message that the time has expired. Chromium is ok.

With Firefox 144, there is unasked for/unwanted AI introduced. How do I ensure that all AI is completely disabled in my browser? I found a link describing some settings, but want to confirm this will disable ALL AI in the browser. I don't want it, don't trust the privacy/security holes yet to be found and would prefer it was not included in Firefox to begin with. The list I've found is:

• user_pref("browser.ml.chat.enabled", false);
• user_pref("browser.ml.chat.menu", false);
• user_pref("browser.ml.chat.page", false);
• user_pref("browser.ml.chat.shortcuts", false);
• user_pref("browser.ml.chat.sidebar", false);
• user_pref("browser.ml.enable", false);
• user_pref("browser.ml.linkPreview.enabled", false);
• user_pref("browser.ml.linkPreview.optin", false);
• user_pref("browser.ml.modelHubRootUrl", "");

Will this do it? What about:

browser.ml.chat.nimbus

Do I need to clear that field to ensure I don't get some auto opt-in in the future as more and more of this "stuff" is put into the browser?

Why not leave Firefox as a security/privacy conscious browser and put out a separate AI browser (FirefoxML?) for those that are not as concerned. How does Mozilla ensure that no information is leaked through AI from sessions for professionals that must protect physician/patient, attorney/client information or other legally confidential information?

For a couple of days now Instagram linked videos won't play here. Actually some of them will -- my own reels and anything linked with that button that looks like a movie 'clapper'. But videos that show the triangular arrow pointing to the right, nothing happens when you click. Not sure if this is a FF issue or maybe something changed at Instagram. Did a google search and nothing came up.

Noticed yesterday but not as prominent, firefox suddenly steals all window focus, trying to do anything in any other window is pushed into firefox no matter if it is minimised or in another workspace. I have tested this in a clean install along with a clean profile. Bitwarden and other windows seem to act weird when they are interacted with.

This all works well and good on b8 and stable. I am using wayland (Ubuntu 22.* default), but xwayland is available.

I created a few virtual hosts and sites on my local machine and this is working perfectly.

Problem is with Firefox, when I enter non-existant url in address bar, Firefox force me to search and don't let me to open the url, but I need to go to this url for testing, developing, etc...

Any solution?

Hi everybody, I am trying to delete an account of mine that I don't use. After I check all the boxes and click "continue" it asks for the password again. I triple checked and it is correct, also because I copy paste it. But the website says "Incorrect password". I tried using a private window to no avail. It fills in automatically the password of another account of mine, which I then replace with the correct one. I did not try leaving there the password of the other account, because I don't want to risk deleting my "good" account. Thank you.

I was using Ubuntu before. I was using firefox and i had lots of recorded logins in that browser. I sign in with my current account and i opened sync including the password and login. Recently i changed my distro, i am using Fedora right now. I log in my firefox account, yet my passwords and logins didn't came back.

I have a new chromebook (Lenova Duet 3) I can install and use Firefox. I have had Dashlane (password keeper) working fine with Firefox for years. The Dashlane extensions work with Chrome, but I can't seem to get them to work with Frefox. The Chrome search engines choices are limited; ones that I never use with Firefox. Is there something in the Chromebook environment that limits firefox capabilities? (Am I looking for something that just is not possible?) Is there a work around? (Any Linux tricks?) I also have asked the same question of Dashlane, but have not heard back yet. My imperfect solution is use Chrome when it is a known website, and the password is recorded with Dashlane, and to use Firefox for new searches, where the choice of search engines is better.

Has anyone developed a search engine where there are no "sponsored" results. I understand that it would probably not be free.

Hi there!

I'm attempting to migrate my Firefox (106.0.3) profile from the Linux Mint V20.3 on one SSD to a new installation of Linux Mint V21 on a separate SSD. I'm using the information supplied on this page:

https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

Step 4, under Backing up your profile says: Right-click on your profile folder (e.g. xxxxxxxx.default), and select Copy.

This folder, qspfoqtl.default, contains 1 file, named times.json, the contents of which are:

{ "created": 1618792039414, "firstUse": null }

Clearly, not my Firefox profile.

There is, however, a folder named nnob5aww.default-release that contains a bunch of directories and files (505.4MB) with names like bookmarkbackups, browser-extension-data... storage, weave.

Is this documentation incorrect as of this release of Firefox? And, should I be using the nnob5aww.default-release folder as the profile? I'm a little confused. (Most often, I'm a lot confused.) Any help would be appreciated.

Thanks in advance,

- Ralph

When I open Firefox after starting my computer, all of my tabs from the previous session are automatically restored, and they take several minutes to load. I don't have the "Open previous windows and tabs" setting enabled. Is there a way to stop Firefox from loading these tabs each time I open the browser?

I'm using Firefox 103 on KDE neon 5.25.

Hello, in past versions of Firefox, I was able to follow the steps on this page to set a custom HTML file on my PC as my home page for new tabs: https://peterries.net/blog/firefox-ubuntu-local-file/

I have Firefox 107.0.1 now and it's not happening. When I open the browser from scratch, I see my custom home page file. But when I open a new tab, I just see a blank screen. If I then click the Home icon on the toolbar, I do see my custom HTML page, but I don't want to have to click that button for each new tab.

Right now, in my settings, I have the URL to the page set as the custom URL for the HTML fiile, like this:

file:///home/peter/Documents/homepage/peter-home-homepage.html

That works. And I also have followed the steps on that blog post to customize my /usr/lib/firefox/autoconfig.cfg and my ../firefox/defalults/pref/autoconfig.js files. That's no longer working.

Did something in a recent version change? Is this no longer supported? Thanks for any ideas!

Beginning with 111 when I start I get 'glxtest: failed to read data from glxtest, we may fall back to software rendering.' It works. I don't know that anything bad is happening.
