When I tried to open Firefox it said "Platform version :130.0.1 is not compatible with minVersion >= 130.0 maxVersion < 130.0

I would like to find the thousands of bookmarks I have saved over the years and get my old setup back up and running.

Thank you to anyone who can help.

The Firefox Sync system is really neat for keeping our booksmarks synced across devices, but what I would also love to see is the option to sync all settings as well, including the changes made in the "about:config" settings.

Across my years of browsing I changed quite a lot of small little things and having to track all of those down every time I set up a new device or reinstall windows can get a bit tedious, so I was wondering if those settings can also be included in the Sync settings somehow - or if such a feature might be planned for the future?

How to recover my Notes. Version 133.0 (64-bit) of Firefox got installed just now on my laptop and all my old Notes (very important stuff) just vanished. How to recover them? Please help..

Hi all,

Fully aware of [https://support.mozilla.org/en-US/que.../1204859], I wonder if there is any way to force a synchronization from one specific browser to others? My scenario is as follows: I use a desktop computer for daily work. This computer is bascially the source of truth. I use literally thousands of tabs, organized w/ Sideberry and multi-accounts containers (~100) (2 profiles in parallel).

From time to time, I use a laptop when commuting or working elsewhere. I'd love to instruct the laptop to receive the latest update (like a git fetch), probably after telling the main computer to "upload" (git push) the latest information and would like to make sure the laptop never can overwrite the desktop information.

Is there any way to implement such a scenario?

Thanks!

I have what i am sure is a common scenario, a work pc (mac) and home pc (linux), and I want to have a work profile and home profile that are independently synced across those PCs.

It's no problem to setup sync for the work profile but while setting up sync for the home profile it seems firefox doesn't grok that the home profile already exists and treats it like a new mozilla account.

In debugging this issue (and the "Primary account email required for sign-in" issue, which prevented me from signing in at all) i've come across numerous articles that imply this basic home<->home work<->work sync across 2 devices does not work with firefox. Is this the case? this is a basic (IMO mandatory) requirement for a browser in 2024 and even the difficulty of setting this up is super jarring coming from Chrome.

Today I was filling in a contract with a government organization. The type that allows me to answer questions and submit. I clicked on something else before finishing and I could not retrieve my work.

I have tried ALL of the suggestions available in HISTORY (restore previous session) open closed tabs etc Etc.

Nothing works

Hello,

I accidentally disliked a thought-provoking story which involved the couple who died in the Lisbon funicular crash (as of Saturday 6th September 2025), which I think was addressed by The Independent.

Is it possible to reverse the dislike? The story does not seem to appear again, at least from what I have seen. Although the dislike was accidental, I felt that having the story disliked would indicate I would not be interested in thought-provoking stories about those who have died, even though these stories should be important to show.

Hi! I am very grateful to anyone who can help me. I re installed windows 11 on my PC and when I reinstall firefox it seems as if the firefox account info is at zeros. Reading after this problem it seems that prior to doing these full re installs firefox requires a backup process but I did not do it at the time even though sync was constantly active. Is there any way to recover all the information from the last sync prior to reinstalling windows?

When I logged into my laptop on 9th November Firefox had closed. This happens sometimes, I'm often not sure why, but this time the previous session didn't automatically repopulate when I restarted. I navigated to the history options with the idea of retoring the previous session - either using that functionality or individually opening previous windows - but history was blank and the previous windows option was greyed out. Following suggestions online I've looked for .bak or .json or similar files to use as restore points but there's nothing since much earlier in the year up to 8th November, which are pretty much empty, and the 9th.

I'd be very grateful for any suggestions!

Hi all. I recently had a terminal problem on my Win 10 computer so have bought a new Win 11 machine. I ran Firefox on the old Win 10, had 5 email accounts, had about 12 local folders and had my Profile stored in a folder on the desktop. The folder was moved there some years ago but don 't remember how I did it. I moved it there because this folder gets backed up every night.

So, I have managed to remove the HDD from my old machine and have located the 'old' profile folder. I now need to re-install Firefox on the new machine and match it up to my old profile folder (I think...)

Any advice on how to do that?

Regards

Steve

For example, say, you have 3 opened tabs in a Firefox (FF) windows. Normally, when you close FF and then re-open FF, it restores 3 previous opened tabs.

But, if you have another FF windows opened at the same time, when you close the FF windows with the 3 opened tabs and re-open back a new FF windows, FF won't restore the 3 opened tabs.

Same thing happens when you have another Private FF windows at the same time, when you close the non-Private FF with the 3 opened tabs, and then you re-open FF, it loses the 3 opened tabs.

That's why you can see 'countless' question about lost opened session, because of the issue above along with crash etc.

Is this a bug or a known feature?

I have created a new Firefox profile. Now I want to copy my settings of the Developer Tools to this new profile. This should also include the custom device settings for the Responsive Design Mode. Is there a file (or files) in the profile-folder that contains these settings, and can I copy this file (or files) to the new profile? I found this link about copying profile files, but it doesn't mention devtools settings.

Hi, I have an issue and hopefully an easy challenge, but I need and would appreciate your kind help.

My Windows 10 PC with Firefox Desktop installed has all my bookmarks, passwords, add-ons, configuration entries, etc. I had the unfortunate situation where my PC hard drive boot-up is corrupted, so I am unable to boot into windows. I am though able to access all of the files intact, via a USB Hard Drive dock to read, save, and be able to transfer any files from that non-bootable hard drive to a new install.

I did a new windows install with a brand new hard drive along with Firefox, but I need your help to effectively get all of those files/entries from the old hard drive and my Firefox "profile" transferred into the new drive so I can resume like before, and further back up as necessary. I do understand that I should have logged into my Firefox account and backed it up so it would have been seamless, but I am sorry I didn't.

Can you please help me and advise?

Thank you so very much.!

I am going round in circles. The last Firefox update reset my Firefox on my laptop to default settings including losing my master password. I started to reset all my old settings but when I got to the part where I setup the sync with my phone version of Firefox, Mozilla asked me to log in. My password was not recognised so I hit "Forgot password" having set up a new password using one of my 10 digit authentication codes, I was then asked to log in with my new password, I did this & when trying to do the sync, I am being asked for a six digit authentication code! I have no idea where to find this code. Please help.
