So I guess my Firefox update to ver. 147 from 146 by its auto update feature, but I realized all the past personal data (ie, history, cookies, passwords, profile, etc) was gone.

I have Mozilla Account (I think it's the same as Firefox Account back in the old days), so my personal data is now retrieved from some device as far as possible, but I lost local personal settings like Shortcuts on the main page on my laptop,p which is the main device to do everything.

I can't help what happened to me, and I will rebuild what I used to be on that day, but I am curious if it's just me, or there is some logic to cause this data loss.

Mozilla support articles frequently state that Firefox does not use popups for browser updates. However, I periodically receive popups from the toolbar stating that Firefox couldn't update automatically. The attached picture is an example from the web but looks just like the popups I receive. The issue typically either resolves itself or I download from the Firefox website and reinstall. In a rush/moment of weakness, I recently clicked the link in the popup. It took me directly to the Firefox website where I regrettably downloaded and updated the browser. I've since run multiple Norton and Malwarebytes scans, which have found no issues. It may be a difference in the definition of popups (from the toolbar vs within a browser page)... Is this a legitimate update message from Firefox? If it is not, are there any other steps I should take (e.g., reinstall Firefox)? I appreciate your help!

Greetings Ya'll,

Early this morning as I went to use the Firefox browser, on My Desktop, I got an update, & then firefox opened, somewhat.

The homepage did not fill in with favorites, suggestions, etc, and in fact all that did load was the Search bar, but not one of my usual website buttons. The "edit", "help", etc. buttons at the upper left hand corner did load, but that is all.

Not one of the buttons work, nor can I close out the Firefox page, by tapping the "X" in the upper right hand corner.

The only way that I could close out the "Firefox Page" was by going through the "Control/Alt/Delete" & then "Signing Out", which would initiate a "Re-start". Once I signed in, I could return to the Desktop, where everything works.

I use Firefox as my Browser on my Android phone, & at this moment, I've not had any problems using Firefox on my Cell Phone.

The only way that I could get to the Mozilla Website was by using the Microsoft Edge Browser, which is not giving me any problems as far as accessing the Internet!

How can I correct this problem, & go back to the Firefox Browser?

Why does not FF recognize that my OS is windows 11, not incorrectly windows 8? This prevents me from updating to latest FF browser versions newer than 115.37 to 128 and higher. Now, with the popularity of AI, my bank no longer supports FF version 115.37 or lower browsers. Might it be FF is not seeing the correct IP address for windows 11 OS? However, I see nowhere on my FF account to let me or FF correct this error. If this cannot be corrected, this I (and thousands of other users) will have to abandon FF for other more up to date browsers because it looks like google, ms and apple are herding their clients to stop recognizing other browsers, which do not support AI protocols.

Every SINGLE time Firefox update now, we have to create a new profile, EVERY SINGLE TIME. We loose all our open tabs, passwords, history, bookmarks, everything.

Why is yours the only browser that does this, and how do we stop this from happening.

This is having an effect that is starting to drive me away from using all your products.

Yesterday I tried to update Firefox to 146.0, but the update failed, consistently. Here's what I did: Seeing the usual "There is a new update available"-pop up, I accepted. "About" screen came up. I clicked the button "update to 146.0", but no download started. I waited about 15 minutes, but still no download. I closed the window. Next, I tried the menu option: "Help->About Firefox". "About" screen came up. I clicked the button "update to 146.0". Same as above, no download.

Before anyone asks the obvious questions: Yes, I was connected to the internet the whole time. I checked that by calling up random pages. No, my firewall was not blocking Firefox. No, it was not just one quirky device. I tried it on laptop and desktop both. Yes, I did close and restart Firefox, I even rebooted the devices, and tried again. Same problem.

Now while my workaround (see below) helped, there is still the question of the update process failing in the first place. For me, that brings up two pressing issues at least: 1. Has anyone external tampered with the update process, maybe with malicious intent? It has happened to several software distributors, most recently the guy behind Notepad ++. 2. What happened to people relying on automatic (i.e. not prompting) updates? Did they even notice they were not being updated?

Not a solution, but a workaround: I synced all my setting to my Firefox-account (worked just fine, no problems), downloaded the newest installer, installed the new version on top of the old (worked like a charm), started new version, all just fine. I did not even need to sync my settings back, all was kept intact. Excellent!

From "About" on the Firefox menu I am trying to download the update from 145.0.2 but it is stalled at 27.1 of 31.3 MB. The little pair of spinning arrows icon just keeps spinning without making any further progress. I'm on a 2020 iMac running Sonoma 14.5 My internet connection is still functioning. I'm wondering what I should do. Is there a way to just cleanly stop and start over? Or stop and continue.

Each time I open the Firefox Icon on my desktop in AVD, it opens an older version and it prompts me to recreate a profile. I updated Firefox yesterday and brought over my passwords and bookmarks. This keeps reoccurring after we fix it each time. Can you help?

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!

I updated to version 146 today on Windows 10 and had to use administrator credentials. I have Mozilla Maintenance Service previously installed. I tried uninstalling MMS and then re-installed FF using full installer and selecting the custom option to install MMS. I cannot see the option in Settings..General 'Use a background service to install updates' (Screenshot attached) How can I fix this issue which has been present for some time?

trying to update old version of Firefox but seeing error code: ssl_error_no_cypher_overlap and the message "no common encryption algorithm" on a MacBook Pro with OS 10.5.8 - - not the machine I'm using in order to seek help
