While trying to troubleshoot a site login problem (ticketmaster.com), I made a backup of my prefs.js, and reset a few hundred preferences in about:config. After finding the pref that caused the problem (tracking), I shut down FF, copied the backup prefs.js in place and restarted. After FF synced, though, my prefs were reset to the previous session with all the reset values.

How do I restore a prefs.js and either *not* fetch the values stored in my online profile, or update my online profile with the values from the file? Is there a timestamp I can update, or some other value to set?

Thanks.

Ever since I updated my Mac OS to Catalina, and updated Firefox to 70, any time I re-start my computer, Firefox does not recognize previous sessions and I have to open my tabs - including pinned tabs - over again. Then I get messages on my other devices saying Firefox has been opened on a new device. It doesn't recognize that I've been running Firefox before.

This morning I noticed new bookmarks on my desktop were no longer syncing to my Android phone. When I tried logging out and in again, I could no longer login on my desktop. Each attempt generates an "Unexpected error" message.

I have already tried the Refresh option from the troubleshooting menu. I also tried uninstalling and reinstalling. After both I am still getting an "Unexpected error" message.

I have also attempted to create a new profile, but attempting to enter an email address produces a 500 error.

Any ideas?

How can configure Firefox to automatically log out of Firefox Sync when the browser is quit?

I know Google Chrome (somewhat infamously) does not allow users to do this, presumably because they want to slurp up as much user history data as possible, but I assumed Mozilla would support this feature. In fact, the *only* reason I just downloaded Firefox and created a sync account was because I expected this feature to exist.

This question was previously asked here https://support.mozilla.org/en-US/questions/1275381 , however the accepted answer does not actually address the asked question.

Good morning, I am using Firefox since 14 years, and all the time it has been my favourite Internet Browser and I advised every friend of mine to choose this internet browser. But I am afraid it's gonna change soon. I lost my laptop, it was stolen. I store my history from a couple of years, bookmarks, saved passwords. I had a backup by MozBackup on May 2019. On December I copied a profile as it was written in your guides: (https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles) I copied everything from: %APPDATA%\Mozilla\Firefox\Profiles\ I hadn't investigate what is inside. And after i bought a new laptop I had many problems with Firefox, can someone explain me please: 1. I couldn't login to Sync, due i hadn't remembered my password - ok its my fault, but when i wanted to reset i would lose all my data?! Why is that? I can understand due to its encrypted but... Luckly after some combination i recovered my password. 2. So i copied my profile as it was written in your guide, and i hadn't investigate what is inside. Now when i tried to copy my whole profile its not working, why? Well, i checked and there were no file: places.sqlite . I have no clue why, so my backup from December is lost. 3. You informed people about Syncing, why there is nowhere information that you syncing history, yes, but only 2 months??!! You claim that we will have bookmarks, saved passwords, cache and history yes thats true, but history for only 8 weeks..... I understand that it has many bytes to store, but it should be somewhere information about it! If i would knew that i would be more prepared for lost, and did more often proper backup by MozBackup. I feel now very frustrated about this situation, and first time after 14 years I'm very, very disappointed with Firefox. Can someone explain me please, why is that? Thank you for reply! Kind regards

Firefox Sync only partially syncing history between two installs (only synced 1% in 3 days)

I've got Firefox 72.0.2 on two systems, one old (10,000+ history items) and one new (200 history items). Both are logged in with the same Firefox account. I've enabled history sync on both and clicked "Sync Now".

The new Firefox install is not getting, at any usable rate, the history from the old Firefox install.

What I've already tried:

1. Log out of my Firefox account on both systems and log in again on both systems. 2. Restart both systems. 3. Disconnect & reconnect from their network connections (obviously, both are browsing the internet just fine) 4. Repeatedly click "Sync Now" in Firefox Options.

System Details:

1. Both are Firefox 72.0.2 and Windows 10 x64 1909 (build 18363) 2. Both are connected to high-speed internet (100 Mbps download / 10 Mbps upload) 3. Both have zero extensions enabled except Bitwarden (password manager).

What is wrong with Firefox Sync here and why is it not syncing any data?

I can't uninstall firefox. When I go to remove programs a message comes up that the computer can't find helper.exe (which is the uninstall program). I then copied and pasted a helper.exe from another computer. I can open the exe as an administrator but then nothing further happens. I also tried downloading firefox again, but it won't install, presumably because I have to uninstall the previous version first.

How do I sync bookmarks from Waterfox Classic to Firefox on the same Mac?

I used to use Firefox but changed to Waterfox Classic a couple of years ago. I have now downloaded Waterfox Current but can't transfer my bookmarks and passwords to the new Waterfox. All the suggestions on the sub-Reddit group do not work because I am not sufficiently computer literate to understand them and/or they are incorrect. Syncing did nothing so I am back on Firefox but syncing here does not bring all the bookmarks from Waterfox Classic to Firefox either. As noted, I am to all intents and purposes computer illiterate plus I am in my mid-seventies with no teenagers around to solve techie problems for me. I really don't want to have to open my bookmarked sites in Firefox and them bookmark them manually, so is there an easy way to get my bookmarks and passwords from Waterfox Classic to Firefox. If so, can someone point me in the direction of an idiot's guide so I can revert to Firefox as my default browser? Thank you

Due to problems with upgrading my Ubuntu to 18.04, I've been forced to use a LIVE DVD for the last 8 months instead of a properly installed Ubuntu. This LIVE DVD crashes or drops out from time to time so each time this happens I have to re-sync the Firefox it brings up. This re-sync requires a verification code to be sent by email, but because that email has to go through my Google filtering process, it usually takes longer than the code's 5 minute validity before I receive it. When I do finally get it and enter the received code back in Firefox, I'm told the code is invalid or expired. This is because 5 minutes validity is just too short a time for my setup. If it were 10 minutes, that would allow me to go into Gmail -> Settings -> Accounts & Import -> Check email from other accounts -> and then order Gmail to perform a special immediate mailcheck on my selected account. As a slow elderly old codger myself, I find it too hard to do all this within 5 minutes. Why can't we make it 10 mins?

FF 72.0.2, Windows 10 desktop. My server sync data was corrupted so I deleted my ff account (changing pw did not delete server sync data) and created a new account with the same email and different password. There are 2 issues with the attempted sync: (note: only the desktop was on and had a ff session)

(1) POSSIBLE SIGN-IN ISSUE: I left the account signed in on accounts.firefox.com after creating the new one and then signed into sync. You can see from the 1st attached image that the sync engine thought there was a different user being signed in and I did get a "New Sign-in to firefox" email. That could be because of my vpn, but the accounts sign in when creating the new account was with the same vpn generated ip as with the sync sign in, so I don't know what's going on there.

(2) SYNC ERRORS: Looking at the 2nd attached image you can see there were unknown problems with the extension-storage engine. While I did not include the complete log file, there did not appear to be any problems with the other engines. In the end syncing failed and the server was flushed. Don't know what extension-storage is?
