Hello Volunteers,

Ubuntu crashes while moving around a Firefox tab with a mouse, IF the mouse cursor goes thru the top bar of the laptop screen. I am using Firefox V 113.0.2, Build ID: 20230522193126 on Ubuntu 23.04. This could be an Ubuntu problem or a Firefox problem.

Thanks Dilip Deodhar

Good morning!

Since v112.0.2 my Firefox logged itself out of Sync and will not allow me log back in. When I click the "Sync and Save Data" in the pulldown menu, the page spinner just spins and spins. The login page never loads.

Oddly, I couldn't even login to my Mozilla account here to post this. I had to use "Ungoogled" Chromium to load the page. I've never had any Sync issues with FF, that I can remember. This just "appeared" with v112.0.2 and continues with v113.0.

I did try to access the Sync login page while in Safe (Troubleshooting) Mode... no difference, though; same spinning spinner.

I'm running Slackware Linux on a desktop computer. No other changes have been made on this system other than upgrading from FF v112.0.1. to v112.0.2. This is when the Sync issue started.

Any ideas? Any assitance would be very much appreciated. I could just go to Chromium full-time, but I would not want to do that. I've been a Mozilla browser user for 23 years. The Chromium is only on my system as a backup browser, along with SeaMonkey. Yeah... I have a Seamonkey. :)

Anyway, thanks in advance for any help/ideas to allow me to troubleshoot/resolve this.

Regards,

~Eric

I don't like Firefox videos showing up in my media player controls, so I turned off media.hardwarekeys.enabled, but it doesn't seem to do anything anymore. I'm pretty sure it used to work at some point, don't know when it stopped working. Even though I have it turned off, videos still appears in the Media Player on my panel, and I can play and pause them with the play/pause button on my keyboard. I have also tried disabling dom.media.mediasession.enabled, but that doesn't help either.

KDE Neon 5.27 Firefox 113.0.2

When I right click a tab I do not get the option to "Send Tab to Device" that I am used to on Windows. Is this missing from the Linux version? Or is there a setting for it?

I have searched the internet for this problem and could not find such things. I would appreciate any help!

I've installed a new version of Ubuntu Linux and - as recommended on this page's FAQs - backed up my firefox profile, than copied it into the profile folder on the new os. Now Firefox tells me "You've launched an older version of firefox" and forces me to create a new profile :( Also loading the old profile in "about:profiles" leads to the same result

How can i restore at least my passwords? (When i try to copy only 4.db and logins.json from the old to the new profile, i get the same result)

I can't find an "import old profile"-function anywhere...

Hi,

I have a policies.json file that acts as a white list for me (black listed all urls and then white listed needed urls). I was wondering is it possible to create a second .json file that will act as a black list. I want to give access to a partial admin. user to the policy.json file to be able to edit the file and add websites if needed but I want a another black list running as well to block out specific websites (this one the partial admin. will not have access to).

So to start off the first question would be is firefox only limited to one .json file for policies or can you have multiple .json files (I want to call the second file blacklist.json)? Btw I use Debian and Firefox-esr.

Thanks.

Currently Firefox is redirecting http://localhost:8080 to http://localhost:8081 , each time when type the address in the URL address bar.

I have been working with a container wordpress. I have tested in chrome the address http://localhost:8080 and all works fine.

How can we fix that problems, thanks in advance.

I have removed cookies and site data of localhost in Privacy-and-security> Manage-data>

Everything under Logins and Passwords, and Forms and Autofill is unchecked. A "Primary Password" has never been set in firefox.

Can't get it to stop asking, which is made worse by the fact that nothing is selected to prompt it nor is anything stored for it to use.

Hi,

I seem to having multiple problems with Firefox over the last few weeks...

This problem is - I can't unblock popups. I have got popup blocking enabled, with a couple of Exceptions - it's been working fine until I wanted to use it today. I have tried turning off popup blocking, re-entering the exceptions - nothing is helping!!!

Does anyone know what to do?

Thanking you Pedro

Hi!

Let's start by saying that I love Firefox, that I use it as my primary browser everywhere and I love that is not based on chromium. However, for reasons to me unknown is missing a very important feature (natively at least): tab grouping. This feature is extremely simple to implement and in today life, where in most jobs (I'm a researcher) you have to deal with a tons of tabs opened in your browser, being able to effectively organize them is a must.

My question is: has Firefox the intention to implement (again) this feature? Will this happen soon?

I'm really trying my best to not switch to a competitor browser and I really want to support Firefox and hope that it gains more and more users. But for this to happen it really needs to be on par with time. How come every other popular browser has a very good tab grouping feature and Firefox doesn't?

Please, let me know if there's a chance to see this feature implemented in reasonable times. Sooner or later, you will probably have to do that reagardless.

Wish you the best, A.

Hi,

i have set my home page to blank. Recently i noticed, that when i start firefox and visit a site, my arrow history (i don't know what it's actually called; the linear browsing history you navigate using those arrows) has the blank page as first entry. I don't want that first entry. How can i get rid of it? (And why is it called "chrome://browser/content/blanktab.html"?) When i open a site in a new tab, i don't have that blank page entry in the arrow history. So it seems like it must be possible to get rid of it.

Same problem with private browsing. The first page is always "about:privatebrowsing".

I'm using Firefox version 108.0 on Linux Mint.

It's only a small annoyance, but i really appreciate being less annoyed.

Thanks

HI! I've been trying to install Firefox on my new Acer Chromebook by following this article: https://support.mozilla.org/en-US/kb/run-firefox-chromeos. However, whenever i get to the last step, it says "no remote refs found similar to firefox". I have no idea what i'm doing at this point, any help?

Malwarebytes & Privacy Badger appear not to be working, though shown as 'enabled' in 'Extensions'. No blocked content is indicated. Adverts appear on lse.co.uk which can cause all four CPU's on Intel i5 to hit hi 90%. This problem appears to have started in this release.

Have disabled Privacy Badger and installed Adblocker Ultimate. This seems to have cleared the problem and Malwarebytes Browser Guard is now reporting results. Can't see how to mark problem as fixed??

A further observation which may be related to this problem. Response time seems very sluggish on FF 112.0.1

I have re-enabled both Privacy Badger & MalwareBytes and disabled Adblocker Ultimate. Both appear to be functioning now.

I have noticed that the WebExtensions process can consume as much and sometimes double the CPU & memory resource as that needed for the Firefox process. Is this to be expected? Do I need these extra security features, or are they built-in to the browser anyway?

I have a few websites, among them glovoapp.com and work Kibana, that don't open properly in my regular Firefox session any more even though I tried to remove cookies related to those websites and anything else I could think of. They work fine in private window but it means I have to authenticate each time. What steps do I need to perform to completely clean a website settings from Firefox memory?

In case of Glovo (and several other websites) in regular Firefox session there's an error: Content Security Policy: The page's settings blocked the loading of a resource at inline ("script-src"). Same doesn't happen in private window.

In case of Kibana (and several other websites) in regular session Firefox somehow remembers old authentication - it doesn't ask for new credentials and doesn't send Sec-Fetch-User header (which results in Kibana throwing HTTP 405 Method Not Allowed). In private window the header is sent correctly.

I'm using Tridactyl so I tried to use the :sanitise glovoapp.com command which, in theory, should remove everything that can be removed with API calls as described on https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/browsingData/DataTypeSet - it's not enough.

Hello all,

For some reason, I can no longer upload or download files, with the pop-up window failing to appear entirely. I can upload folders through, for example, Dropbox or Google Drive, but individual files don't work.

I've reset my browser, uninstalled and reinstalled it, opened it in troubleshooting mode, disabled enhanced tracking protection, but nothing seemed to work. I've tested another browser, and I was able to upload and download files just fine.

Is there anything I can do to fix this? I'm on Ubuntu 22.04 using Firefox 107.0.1.

FF keeps replacing

http://mysite.domain.net:3344 with httpS://mysite.domain.net:3344

whatever I try to fix this behavior. Thing is that I own this server and there ever was't any SSL implemented. I mean this - never.

Other browsers (Chromium, Chrome, Opera) don't take such a forcing action, website opens like a charm. Why FF thinks it knows better which URL I really want to open?

I already googled _a lot_ in order to find solution, but no one worked.

Setup: Debian 11 Mate no proxy and no separate "internet security" stuff on laptop (other browsers with default settings confirm that) FF 102.11.0 ESR 64 no addons (all switched off)

already tried: browser.urlbar.autoFill false browser.cache.check_doc_frequency 1 network.stricttransportsecurity.preloadlist false browser.fixup.fallback-to-https false dom.security.https_first false

What else I could do to stop this madness? Thank you in advance for any help

I am trying to have Firefox show an "X" on every tab as soon as I hover above it. I followed a certain article and implemented this code:

/* Show Tab Close buttons only when hovered */

1. tabbrowser-tabs > .tabbrowser-tab:not([pinned="true"]) > .tab-stack > .tab-content > .tab-close-button {

 visibility: collapse !important;
 opacity: 0 !important;
 transition: all 250ms ease-in-out !important;

}

1. tabbrowser-tabs > .tabbrowser-tab:not([pinned="true"]):hover > .tab-stack > .tab-content > .tab-close-button {

 visibility: visible !important;
 opacity: 1 !important;
 transition: all 250ms ease-in-out !important;;

}

1. tabbrowser-tabs > .tabbrowser-tab:not([pinned="true"]) > .tab-stack > .tab-content > .tab-close-button {

 display: -moz-box !important;

}

This code is however not being implemented no matter how many times I restart Firefox. 'toolkit.legacyUserProfileCustomizations.stylesheets' is set to True The location is userChrome.css is '/home/user1/.mozilla/firefox/yqomjsh9.default-release-1672744596809/chrome/userChrome.css'

What could be the issue? I tried adding executable permissions using "chmod" but that did not change anything.
