I am trying to create a backup of FireFox for moving from a Windows 10 machine to a new Windows 11 machine. The instructions for creating a backup don't make any sense.

--- Click the main menu, and go to Settings. Select Sync. Scroll down to Backup, and click Manage backup. Choose the location to save the backup file. ---

When I click the Main Menu, go to Settings, Select Sync, there is no Backup listed. If I search for the term "Backup", this is the result: "Sorry! There are no results in Settings for “backup”. Need help? Visit Firefox Support".

Syncing is on, so I am assuming that FireFox is being backup?? Or am I missing something somewhere?

Hello,

I am having an issue with my Instagram account on PC (web version).

I can log in successfully, but after logging in the page does not load. It only shows the Instagram logo and stays stuck on the loading screen. Refreshing the page does not help.

Important details:

Instagram works normally on my mobile phone (app)

The account is not blocked or disabled

I changed my password successfully

I tried different browsers (Firefox, Edge, Chrome)

I cleared cache and cookies

I tried private/incognito mode

The problem only happens on PC, not on mobile

Because everything works fine on my phone, I believe this is a problem with the Instagram web version or a browser-related issue on your side.

Please check my account and let me know how I can fix this or regain normal access on PC.

Thank you for your help.

Which data are stored in "User Data" and how to clear this kind of stored data? When deleting data in the privacy settings in Firefox, the "User Data" storage is still unchanged. Also "Cache" is not cleared completely.

The "User Data" raises up to 1GB. It is only possible to clear it by completely wiping all data via "Clear Storage" but then everything is wiped, also all Firefox settings etc. "Clear Cache" obviously only wipes the Cache.

Hi everyone,

I’m using Firefox for Android on a fairly recent device and wanted to ask about performance when running web-based applications that are a bit heavier than normal websites.

Specifically, when using browser-based emulation tools or interactive web apps, I notice higher memory usage, occasional tab reloads, and sometimes audio or input lag after a few minutes. This doesn’t always happen on simpler sites, so it feels related to how Firefox handles long-running JavaScript and WebAssembly workloads on Android.

I wanted to ask:

Are there any recommended Firefox settings or flags to improve performance for heavier web apps?

Is Firefox for Android known to aggressively suspend tabs under memory pressure?

Would using private tabs, disabling certain features, or changing about: config settings help in this case?

I’m mainly trying to understand whether this is expected behavior or if there are optimizations I can apply.

Thanks in advance for any guidance.

I can't read my mails and every time i open Thunderbird i get told that my registration failed and i have 3 Options to choose "try again", "enter new password" and "cancel". Doesnt matter ehich one I choose i can't read my mails or receive any and the same message and the same options pop up again.

Hi,

In the search bar (I’m not sure about its official name), my previous searches used to appear as suggestions before Google’s own suggestions. However, since I changed my default search engine from Google US to Google UK, it no longer seems to remember the searches I make. I’ve tried switching back to Google US, but that didn’t restore the behavior. Do you have any idea how to fix this?

For example, I previously searched for “things to see in Latvia”, which is why it appears as a suggestion in the screenshot. But if I now search for “things to see in Louvre Museum” and then try the same search again a few hours or days later, it isn’t saved and therefore doesn’t appear as a suggestion.

Thank you!

Hello,

When I try to visit a specific journal site that requires authentication, the browser automatically redirects me to an authentication page that I have used before. This is very annoying because every time I click a link to the journal, I’m sent to the other portal and can’t access the article. I want to stress that I haven’t installed any add‑on that would cause this redirection. I think I did that myself manually but I have no idea how. I’ve already deleted the cookies for both sites, but nothing has changed. I hope that makes sense, it’s a bit difficult to explain.

I'm using firefox 147.0, on mac Tahoe 26.2.

Thanks for the help !

When right-clicking on the Firefox icon in the Windows task bar one can pin entries, which then appear in the "Pinned" section of that menu. The description is taken from the title of the website at that point in time.

I would like to rename one such entry (i.e. change the description). How can I do this? The context menu only contains the options "Open" and "Unpin from this list".

hi, I love supporting this independent browser - I know its not perfect but it does a great job of doing most things well.

However, and there is a big but. I can be in the middle of an investigation that requires sharing data to a new tab - on opening the tab I'm blocked from going further as Firefox needs to do an update! This is really infuriating. No update can be SO urgent that you stop me using the browser. This is the Microsoft mentality, and its wrong. Can you please investigate NOT forcing users to update their browser during session.

Matt.

When right-clicking on the Firefox icon in the Windows task bar one has the option to "pin" items by hovering over an entry in the "frequent" list and clicking on the little pin needle icon (with the hover text "Pin to this list").

How can I pin items that are not in the frequent list? I have tried for weeks to make an important page a frequent one by making sure to visit it daily but it never makes it to the list.

In `about:config` I set `mousewheel.with_control.action: 3` quite a while ago, and today, after an update it stopped working. Current version: `146.0.1 (aarch64)`. Any idea why?
