I'm using Firefox 104.0.2 (64 bit) under Windows 11.

Under Settings I have selected Startup Open Previous Windows and Tabs.

I normally have more than a dozen tabs.

For the past few days, when I start Firefox my previous session is not restored and I just get the single Firefox tab.

When I got to History there is no longer a Restore Previous Session option.

How do I get it back?

Thanks

I have tried searching all self help topics. I have tried all available settings options. I have upgraded to the latest version 104.0.2. However, nothing seems to fix my problem which is that Firefox will not restore my previously open tabs when I reopen it. This problem started a few weeks ago. I have selected [Open previous windows and tabs] I have selected [Firefox will remember History]

Can you please help

Thanks Fred

Since the upgrade to Firefox 104.0.2, the only option when printing is to select "Save to PDF". All other apps can printer to any of my printers. I have to save as a pdf then print the document using the PDF viewer. I have HP4100 & HP9025 printers on my network, that all other apps can see and print to. I've refreshed Firefox & re-installed Firefox but the problem still persists. The System's printer dialog shows that both printers are available and changing default, or reinstalling the printers makes no difference. OS is Ubuntu 22.04.1 LTS.

Screenshots show the printer window in Firefox, and the Printer Settings from the OS Settings window.

I'm having an issue with Netflix, i am unable to play anything there at all. It always shows a message saying "firefox is installing components needed to play the audio or video on this page" and refuses to load anything, showing an error, F7701-1003.

After some investigation, i found out that the issue is with Firefox not loading "Widevine Content Decryption Module provided by Google Inc.". I have seasrched and tried several troubleshooting processes, and was unable to find a solution. Refreshing, reinstalling, manually deleting the profile folder, all fails

I've just rebooted and I've lost two windows with thirty tabs, or something.

When I started Firefox, there's nothing in the Recently Closed [Tabs, Windows]

Reading online, I see that Firefox should be writing some files to the sessionstore-backup directory, like these:

recovery.jsonlz4: the windows and tabs in your currently live Firefox session (or, if Firefox crashed at the last shutdown and is still closed, your last session) recovery.baklz4: a backup copy of recovery.jsonlz4 previous.jsonlz4: the windows and tabs in your last Firefox session upgrade.jsonlz4-build_id: the windows and tabs in the Firefox session that was live at the time of your last update

, but I only find recovery.jsonlz4 and recovery.baklz4 and both are tracking current time, which means they are getting data from the currently opened Firefox.

These are the only files I find in this directory.

Where are the other files supposed to have gone?

Hi!

I want to use my own unsigned addon with my daily browsing. But I found out that firefox hates it's user base by making xpinstall.signatures.required option in about:config only available to dev builds.

If I use firefox dev build will I loose on performance? For example is it compiled with debug symbols that slow down code execution? And if so, is it somehow possible to get the release version of firefox where xpinstall.signatures.required is set false so that I would not loose because of dev build?

Running WIN10. I have used FF w Google for about 20 years, and always had new searches open in same window, new tab. Following recent refresh of FF, that seems to be not possible. Links open in new tab, but not searches. In about:config the browser.search.openintab setting is True

I have closed and reopened FF, and closed and reopened WIN10.

What might be over-riding this? Many thanks!

Hello!

I'm using Firefox MSIX on a laptop with an OLED screen. To avoid burn-in, static elements on the screen are discouraged.

Unfortunately, when the Reader View is enabled on Firefox, a vertical toolbar appears and is constantly on the same spot on the screen.

I would like to have this toolbar disabled or have it to hide/show depending on mouse prompt. Is there a built-in setting I could change to make this happen?

Would this solution here be my only option and would it work on Firefox MSIX? Finding the firefox profile on the Microsoft Store app is tricky.

Thank you.

Hi Mozilla community,

The Developer Tools -> Storage -> Cookies pane shows cookies currently being stored by Firefox.

If I close my browser, these cookies are automatically deleted. However, if I follow the steps on [1], the cookies are still there, and don't get deleted. *Why?*

Thanks in advance!

Steps to reproduce:

- Start a new Firefox session
- Open Developer Tools -> Storage -> Cookies and see that the list is empty
- Go to youtube.com and click Accept All on the cookies popup
- Developer Tools -> Storage -> Cookies now shows a cookie from YouTube, as per the attached screenshot
- Go to Settings->Privacy & Security->Cookies and Site Data -> Clear Data -> Clear
- Go back to Developer Tools -> Storage -> Cookies and click on the refresh icon
- The YouTube cookie is still there
- However either of the following actions will correctly delete this cookie:

1) closing firefox (with Always Use Private Browsing Mode enabled) 2) manually deleting the cookie from the list in Developer Tools -> Storage -> Cookies

Hi all, is expired cookies management changed lately? Authentication doesn't work anymore in following use case. Question is all about FF for windows, while usually I'm on FF Android, Edge and Chrome for Windows and all these browsers are working correctly.

My working web app (static blazor wasm standalone) is interactively authenticating in Azure AD B2C using Microsoft.Authentication.WebAssembly.Msal library (like MSAL.js), API is an Azure Function protected through AAD B2C.

Login request successfully invokes Signin/Signup B2C flow with popup to myb2ctenant.b2clogin.com but breaks navigating to auth protected pages or backend apis.

From DevTools I see that every request to following b2c endpoints sets an expired cookie (expired 10 years before, year is now 2012):

When user clicks login: GET /myb2ctenant.onmicrosoft.com/b2c_1_sinsup/v2.0/.well-known/openid-configuration

Returning from login confirmation: GET /myb2ctenant.onmicrosoft.com/B2C_1_SInSUp/api/CombinedSigninAndSignup/confirmed?rememberMe=false&csrf_token=xxx

for example: Set-Cookie: x-ms-cpim-trans=; domain=myb2ctenant.b2clogin.com; expires=Fri, 14-Sep-2012 12:46:46 GMT; path=/; SameSite=None; secure; HttpOnly

FF registers this warning in console:

Cookie “x-ms-cpim-trans” has been rejected because it is already expired

Following when MSAL execute a request to /myb2ctenant.onmicrosoft.com/b2c_1_sinsup/oauth2/v2.0/authorize?xxxx

Response always contains:

Location: https://blazorapp.xx.web.core.windows.net/authentication/login-callback#error= interaction_required&error_description=AADB2C90077%3a+User+does+not+have+an+existing+session+and+request+prompt+parameter+has+a+value+of+%27None%27.%0d%0a

All other browsers are working... Thanks in advance for any help
