Every time I start up firefox, it takes about a full minute to load. It shows an outline of the UI, but does not become usable for a while, windows also puts up a "firefox is not responding" window when the window is interacted with. After loading, opening a new window is unaffected, and page loading is snappy. just the initial launch is the issue. This remains true even after a clean uninstall + reinstall. Appdata folder was removed as well, and did not affect the issue. I do not have any antivirus software other than windows defender, so that should not be an issue. My hardware is also not likely to be at fault, as it is sufficiently up to date (upgraded within last year, not sharing specs here). Chrome starts up in less than a second for reference. Once again, a fresh install with a new profile has the same symptoms. Have tried every available guide to no effect.

This morning my Linux Mint PC notified me via Update Manager that an update to FF version 126 was available. I ran the update and it completed with no problems. I use FF as a Flatpak. When I checked the FF version in FF Help>About FF it still showed version 125.0.3 even after restarting FF and the PC. I checked the Synaptic Package Manager on my PC and it shows that my current FF version is 126. The Software Manager shows the current version is 125.0.3. Why is FF still showing the previous version after I ran the update for 126? I'm concerned that I might have a compromised FF even though I updated it via Linux Mint Update Manager like I always do for any program updates. Thank you, Colin

FIREFOX won't print whole day of my google calendar - now it just prints when I get to the computer and print out the day - but then it skips the morning or night - BUT I can go to Chrome and it will print from 6am to 12midnight .... PLEASE get this fixed - such a pain to log in to another calendar/browser ETC all the time

I am trying to configure Firefox on macOS to not prompt the user to make it the default browser.

I am using the following script to create the profile and set the user preferences after installing Firefox by copying `Firefox.app` from the downloaded DMG: ```

1. !/bin/sh

open -a Firefox.app --args -CreateProfile default sleep 1

write_userpref() { USER=$(whoami) PROFILE=$(ls -1 "/Users/${USER}/Library/Application Support/Firefox/Profiles/" | grep -E "\.default$") cat << EOF > "/Users/${USER}/Library/Application Support/Firefox/Profiles/${PROFILE}/user.js" // mandatory comment? user_pref("app.update.auto", false); user_pref("app.update.disable_button.showUpdateHistory", false); user_pref("app.update.enabled", false); user_pref("breakpad.reportURL", ""); user_pref("browser.newtabpage.activity-stream.feeds.topsites", false); user_pref("browser.newtabpage.activity-stream.feeds.section.topstories", false); user_pref("browser.tabs.crashReporting.sendReport", false); user_pref("browser.discovery.enabled", false); user_pref("browser.defaultbrowser.notificationbar", false); user_pref("browser.shell.checkDefaultBrowser", false); user_pref("browser.shell.didSkipDefaultBrowserCheckOnFirstRun", false); user_pref("browser.shell.skipDefaultBrowserCheckOnFirstRun", true); user_pref("browser.newtabpage.enabled", false); user_pref("experiments.enabled", false); user_pref("extensions.pocket.enabled", false); user_pref("toolkit.telemetry.enabled", false); user_pref("update_notifications.enabled", false); EOF }

write_userpref

open -a Firefox.app --args -new-tab -P default "about:blank" sleep 3 osascript -e 'quit app "Firefox"' sleep 2

open -a Firefox.app --args -P default about:blank ```

Here's the behaviour I'm seeing:

1. Firefox starts to an `about:blank` tab, however there is a second "Firefox Privacy Notice" tab
2. AppleScript quits Firefox
3. Firefox starts to an `about:blank` tab, however it is now prompting me to make it the default browser

I do not want Firefox to prompt the user to become the default browser.

My ideal scenario is that Firefox starts without the "Firefox Privacy Notice" tab and without prompting me to make it the default browser. From the observed behaviour, this doesn't seem possible.

Can anyone tell me how I can accomplish this without user interaction or MDM?

Today I noticed that typing characters with accents like á, ã, â, etc. doesn't seem to work at all from firefox, they all end up ignoring the dead key and just typing the letter itself. It can render them just fine and I can paste them from another app normally too, but actually typing them is impossible from firefox.

After trying to troubleshoot, I eventually found out a few things: - iBus is not at fault, since it works in every other app and I even restarted it, but the problem persists - This only happens in my main profile, newly created profiles don't have that problem - The problem still happens on troubleshoot mode (as long as it is my main profile) - Compose key also doesn't work (I don't want to use compose key anyway, because my keyboard has specialized dead keys, but I at least tried it)

I suspect the problem lies in a setting on about:config that's different from newly created profiles, but I have no idea which and Ctrl+F searching this site doesn't show any relevant configuration that might be the culprit.

Today while using firefox all my open tabs and windows crashed. Due to the situation, I had to restart my computer because everything was stuck. When it restarted I couldn't restore the previous session so I used various methods to restore it but I still can't restore the windows and tabs that were open today. I would like you to restore my session from before the failure today.

Hello dear community,

I have a program that continuously monitors the download folder under Windows 11 for a specific file and retrieves it. I download this file in Firefox, but the said program gives an error.

I have noticed that when files are downloaded in FireFox, they already appear in the Downloads folder with the corresponding file extension with 0 bytes and these are then apparently swapped or merged with the .parts file.

The problem is that the mentioned program now tries to retrieve the unfinished file, which then leads to an error.

Does anyone know if it is possible to customize Firefox so that the file only appears in the download folder when the download is fully complete?

Many thanks for your help :D

After the last Firefox update: - i was logged out of my mozilla account; - i was logged out of my Facebook account; - i was logged out of my bluesky account; - i was logged out of my Facebook account; - my Instagram account is suspended;

yesterday morning all of these were logged-in and working fine.

Had to work for 30 minutes to re-log-in. And I cannot reactivate Instagram, I contacted support, nothing yet.

I have many rare bookmarks. This time I sell my old laptop and rent another laptop. The laptop rental a strange windows version (probably a hack one) and some strange apps (like 360 what what), I uninstalled the 360 what what apps. Then I downloaded and installed firefox and open all bookmarks become 365whatwhat. I did not care it so much, I logged in my firefox account, but the bookmarks did not change! I click sync, all the bookmarks are still 365 or 360 whatwhat. All my previous bookmarks are lost. How to recover?

Sorry to have this same issue again, knowing full well it can happen after finding this some years ago (https://support.mozilla.org/en-US/questions/1319823), I tried to carefully connect two older PC devices back to firefox sync, however on one I managed to enable sync before disconnecting my profile (it seemed as if reconnecting sync temporarily was the only way to disconnect a profile from firefox's UI - I should have been more careful and removed the profile from the filesystem level): at which point I polluted the sync server.

I've noticed that `about:sync` has an option under bookmarks/engine actions 'wipe bookmarks', which sounds exactly what I need, and if I watch what happens once pressed it does the right thing and repopulates the sever with the 'correct' PC's bookmark set (when run from that PC), however it also says 'other devices will act like a reset', which i'm finding NOT to be the case: eventually one of my other device repollutes the server with bad bookmarks which propogate.

I'm thinking the culprits are my phones, If I wipe and do a sync on a phone, my phone's bookmarks stay polluted. If i'm right about that, I think my question is: can I wipe my profile (or preferably only my bookmarks) from my phones' Firefox without having to entirely uninstall/reinstall (or do you have any other advice for not re-polluting the server from some already-polluted device's bookmarks?

thanks in advance

Hi everyone,

I'm used to typing one or two letters into the address bar and then the down arrow to access the same handful of websites every day. A few weeks ago, Firefox started randomly moving these around so that the same letters that have always made it open the same URL now opens a different URL and I have to actually search the suggestions. How can this annoying behaviour be fixed?

(a few months ago, the address bar wouldn't delete entries, but this problem vanished as mysteriously as it appeared)

FF version 122.0.1 (64-bit), Windows 10

whenever i close a single open tab, firefox closes and i have to reopen it to my home page. In the past i could actually revert back to my home page after closing tabs. And then can only close down firefox by hitting the top right X. Unfortunately i have forgotten what i did last time, so any help would be appreciated Ta Doug G

I just did the most recent Windows 10 updates:

KB5037768, KB5038350, KB5001716

My version is 22H2 for x64 and .Net 6.0.30

Upon finishing the update and rebooting, Firefox gave me the PR_CONNECT_RESET_ERROR on all websites. Not other browser was having an issue. I've tried all the troubleshooting steps I can find. Is there an error fix based on what I am describing that I can now try?

Thanks!
