I am trying to find a way to restore the previous tabs that I had open. All the standard restore procedures out of the History button or elsewhere are not working due to the account change. Here's the background and scenario: Original account created 1 month ago on old Linux PC New PC purchased and Ubuntu Linux 24.04 installed Firefox installed and configured, bookmarks imported from .html file. No sync account was ever signed in to. Open a crapload of tabs that I wanted/needed to interact with (yes, I need a better task management system) Finally decide to log into sync account, successful sign-in Close browser for PC restart. Upon restart, all configurations from 1 month ago on old Linux PC are present, and no previously-opened tabs come back. Restore session/restore tabs/restore browser all are greyed out, no data to access in history anywhere. Signed out of account, closed browser window and restarted. Still displaying config from old sync account even when not logged in (different theme, toolbar settings)

I am unable to locate any files in the pathway Home/snap/firefox/common/.mozilla/firefox that clearly indicate multiple profiles; there is only one distinct profile folder present. I haven't cleared cache or anything, trying to not touch it more. Is it possible to restore or even see the URLs of those tabs from my session prior to logging in to my sync profile?

I have a new Mozilla (FireFox) account and keep getting emails that say I need to confirm it. They include a button to do so but I'm not clicking it unless I get better information from you. Please help. The email swears my account will be deleted if I don't confirm it. What do I do?

Scrolling in Firefox is causing any webpage to scroll many lines at once with a single click, and it seems to be exclusively happening to Firefox, as every other application scrolls normally. I have tried searching here and elsewhere for a solution, and I have tried to change about:config settings based on the recommendations I could find to no avail. I have also tried to refresh Firefox and have used Troubleshoot Mode, but those too have not worked. I have no clue as to what could have caused this, as I have not been messing with any settings prior to this.

i cannot print any web page from Firefox. The print option only offers me the option to save as PDF. Firefox is not detecting either my Brother laser printer or my Epson inkjet printer. if i use the print using system dialogue option fire fox shows a printer screen which has a simple entry of line prntr. If that is selected nothing at all happens. Clearly Firefox cannot detect my printers. If I save the web pages to a PDF file then open that file I can then get the normal system printing options and print the page. But all that does is clutter up my file system with files I will only ever use once. This proves the problem is clearly in Firefox and in its inability to detect system printers. I have tried all the suggestions from the help screens to no avail. Is there any other means of sorting this print problem.

I just want to stop a piece of my own history from being shown on "Firefox Suggestion", which was made with a firefox browser on my previous device and is relatively private.(I know I can do this by modifying "Search Suggestions->Show search suggestions ahead of browsing history in address bar results", but I would like to preserve the function itself). That device is permanently unapproachable, and so is that browser. I tried "Clear recent history -> Everything", but it didn't work as expected and that is still shown. I think clear all my history(not only those made on this currently used device) may help, how can I do it?

I signed onto my parents computer that was assigned to a school district and now everytime I open firefox on any of my devices their website keeps popping up. I've signed out of their computer and have tried deleting and reopening my account, and nothing seems to work.

I've been using Firefox and it's saved numerous passwords. However, these disappeared suddenly. Through testing, I discovered they reappear when I restart Firefox in Safe Mode (achieved via about:profiles => restart with adds-on disabled). Yet, re-enabling add-ons (restart in normal mode) causes the passwords to vanish again. Interestingly, disabling the add-ons in normal mode doesn't restore password access.

Looking for solutions or insights.

Is it possible to make a donation to Mozilla without providing so much personal information? I got a message on Firefox today asking for a donation, but when I tried to do that, I was asked for my home address. It's a general rule of internet marketing that people who use the internet would rather do anything than pay for something, so it's bad psychology to impose unnecessary conditions when you're asking for a donation. I don't have to provide my home address when I make donations to other organisations, so why does Mozilla need my home address? I apologize if this is the wrong place to ask this question, but I can't find anywhere else to ask it!

Thanks,

Shaun.

When I opened Firefox[^1] today I was greeted with a "Donate to Mozilla Foundation" page open, with the message:

"You power Firefox. Now donate to make good tech the default.

Mozilla Foundation — the non-profit behind Firefox — is building a future where technology serves people, not power.

Your donation to Mozilla Foundation keeps the internet open, private, and built for people. Donate today to make good on the promise of the internet."

Does this message mean that Donations to the Mozilla Foundation now fund Firefox development? As I understand it, previously donations were not allowed to be used by the Mozilla Corporation, which actually develops Firefox. I'd love to donate to fund Firefox development, as I feel it is a critically important open source project.

[^1]: 145.0.2 from the Mozilla Debian repository.

Hi,

I like to use separate user accounts / X sessions for work and personal stuff. Whenever I switch from one session to another (ctrl+alt+Fx), it usually takes a few minutes for Firefox to get responsive again. Sometimes it never does (typically on Mondays, after working in my "personal" session all week end, and switching back to my "work" session). Other applications (xterm, qpdfviewer, etc...) don't seem to be affected at all. Is there something I can do to fix that ?

Thanks,

 -Olivier.

Firefox Sync code doesn't arrive; my email's support (Proton Mail) says you have «likely added you to their suppression (do-not-send) list automatically.».

So I request you remove the e-mail associated with my account, the one used in this post, from the do-not-send list.

Thank you.

I hover over bookmark folder, they expand, and the links the folder contains work. (Or) now 80 percent of the time, I hover over the bookmark folder, they don't expand, so I click on the folder to expand it, and 90 percent of the time, the links in the folder do nothing when clicked on. They won't even get highlighted, (selected) I restart firefox, and all works again, for about 10 seconds, and problem occurs again. It goes without saying it gets real frustrating restarting firefox over and over and over again to use another bookmark. I've never experienced this before. This only happens for me on firefox for Linux Mint 22.1. Firefox on windows 11 does not exhibit this problem. Please help, thanks. Cheers...

Hello, maybe someone else seen the same issue.

Why Firefox could respond with VP8 to the H264 request?

The setting works...in the way that if i quit Firefox, it'll not continue from the tabs and windows, but if i reboot my pc and open Firefox, I find myself the same place i stopped...even though i have that setting disabled. I found someone else with same issue on reddit and i did the same restarting the browser and refreshing and all....all to no effect.

In Linux Ubuntu I created 4 different launchers for 4 profiles.

Firefox opens the different profiles correctly, but the name of Profile 4 is displayed in the title bar for all windows. This causes confusion when I'm using the different profiles. Furthermore, the icon displayed in the icon bar is also the same for the 4 profiles, although I have configured a different icon for each profile. I ask for help as I need each instance to have its own name and icon displayed correctly.

The launchers look like this:

firefox-profile1.desktop: Name= Profile 1 Exec=firefox -P profile1 --no-remote Icon=~/.local/share/icons/profile1.png

firefox-profile2.desktop Name=Profile 2 Exec=firefox -P profile2 --no-remote Icon=~/.local/share/icons/profile2.png

firefox-profile3.desktop Name=Profile 3 Exec=firefox -P profile3 --no-remote Icon=~/.local/share/icons/profile3.png

firefox-profile4.desktop Name=Profile 4 Exec=firefox -P profile4 --no-remote Icon=~/.local/share/icons/profile4.png

I want to visit http://bispebjerghospital.dk/ . I have seen on https://www.whatsmydns.net/#A/www.bispebjerghospital.dk that it's DNS isn't propagating correctly, so I turned on "MAX PROTECTION" for DNS, hoping that it would let me see the site.

But Firefox showed me "Unexpected error" the first time I went to the site. And then I clicked 'always allow' and now it just spins and spins with no response visible.

How can I visit the website from one of the countries with red X's on whatsmydns?

I installed firefox on ubuntu 24.04 following the guidelines from https://support.mozilla.org/en-US/kb/install-firefox-linux

I followed the direction from the section "Install Firefox .deb package for Debian-based distributions", adding the https://packages.mozilla.org/apt repository, prioritizing that over firefox snap from ubunto repors and finally installing firefox.

All good, now I have the latest firefox.

Question: what entry should I add to the "Unattended-Upgrade::Allowed-Origins" section of "/etc/apt/apt.conf.d/50unattended-upgrades" in order to enable unattended upgrades for the mozilla repo?

Googling this got me different contradictory recommendations that did not get my system to firefox 146 until I manually run the apt update/upgrade.

Thanks!
