My laptop unexpectedly closed Firefox after it crashed and upon a restart I re-opened Firefox, which normally restores all my open windows/tabs from the very last session no problem whenever it force quits due to laptop crashes. But this time when opening, it restored windows/tabs from almost a month ago. I closed Firefox and checked the sessionstore-backups folder: - the recovery-backup files are from the session date I just re-opened with old tabs - the previous.jsonlz4 file is from about a month ago and seems to be the reference point used when restoring tabs rather than my actual last session

Is there any other file or method I could use to recover my actual prior session tabs before it crashed?

I have not re-opened Firefox since quitting the browser after seeing it restored the old tabs.

Thank you in advance!

Hello,

I am encountering an interface display issue while using the AdGuard ad blocker extension in the Firefox browser on Windows. When I try to open the "Filtering Log" feature within the extension, the pop-up window appears completely blank and fails to display any log content.

Steps to Reproduce the Issue:

1. 1 Install and enable the AdGuard extension from the official add-on store.
2. 2 Browse any website.
3. 3 Click the AdGuard icon in the Firefox toolbar.
4. 4 Click the "Filtering Log" button (the icon that looks like a list or clipboard).
5. 5 Expected Result: The filtering log window should open normally, displaying a list of blocked and allowed requests.
6. 6 Actual Result: A new window pops up. The title bar of this window displays "Mozilla Firefox," but the content inside the window is completely blank (pure white, without any text or error messages).

Additional Information:

• Firefox Version: 142.0.1 (64 bit)
• AdGuard Extension Version: 5.1.139 (TSWebExtension v3.1.0-alpha.4 TSUrlFilter v3.3.3 Scriptlets v2.1.6 ExtendedCss v2.1.1)
• Operating System: Windows 10 22H2

Other Installed Extensions:

• Immersive Translate - Translate Website & PDF | by Immersive Translate | Version 1.20.8 | https://addons.mozilla.org/en-US/firefox/addon/immersive-translate/;
• Tampermonkey | by Jan Biniok | Version 5.3.3 | https://addons.mozilla.org/en-US/firefox/addon/tampermonkey/;
• Dark Reader | by Dark Reader Ltd | Version 4.9.110 | https://addons.mozilla.org/en-US/firefox/addon/darkreader/

Troubleshooting Steps I Have Already Attempted:

• Restarted Firefox.
• Disabled and re-enabled the AdGuard extension.
• Reinstalled the AdGuard extension.
• Tried running Firefox in Safe Mode (with all extensions disabled). The issue persists, suggesting it may not be a conflict with other extensions.

This issue prevents me from using AdGuard's core debugging functionality. Thank you for your assistance.

I feel like I've tried everything to stop Firefox from automatically opening when I start my Windows 11 computer.

I've checked: task manager, the startup folder in Windows 11 (shell:startup), The registry under "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run", Settings>Apps>Startup, and also in Firefox under Settings>"Open Firefox automatically when your computer starts up", and under "about:config">toolkit.winRegisterApplicationRestart (change value to false).

Can anyone tell me why Firefox is still automatically launching at startup of Windows 11?

I am a long time user of firefox, but over at least the last six months I find that I have to use another browser to log into or use various websites - and I find it very difficult to contact you to try to find remedy. Started out several months ago. Could not verify - captcha - had to use Brave to complete login to complete purchase of subscription. Happening more often as time passes. I can complete logins only when I switch to Brave or Vivaldi. Do not want to switch browsers, but becoming more and more likely.

Why am I getting this message: with no way around it?

There are four tabs on the tab line that did not close out when I turned off the computer. Each time I come on the tabs are still there. I can close them out individually but they come on again when I sign in again. Also, I can not use the "home" button to utilize Google.

After tinkering with about:config (shouldn't have...) the background of every page that does not specify a body background color turns the color of my theme background color.

Using the firefox color pipette says its white, but it clearly isn't.

The theme i have is dark, making any page that expects the background to be white unreadable (without DevTools -> Body -> background-color: white)

I haven't been able to find the config that fixes it.

Hi,

I started to notice recently that calendars in some websites I browse with Mozilla are inaccurate. The dates like months, days,... are in a mess. Then I used Google Chrome instead of Mozilla and it went right. It was accurate with Chrome browsing those sites. Did you hear of the same problems with Mozilla ? What can be wrong ?

Thanks for your insights,

All the best,

Denis

I tried downloading an APK from memesAPK] but Firefox didn’t save it properly it just showed up weird instead of a normal APK file. Has anyone else run into this or know how to fix it?

I just had another credit card get fraudulent charges. I have no clue how they are getting my card numbers, I have pulled all but 1 from anywhere online, but they just got another one. I couldn't get Mozilla VPN to work it just quit working at all. I turned Pocket off but I'm still getting 17 to 18 instances of Firefox. Dont know where to go now. Thinking of pulling the plug and starting over.
