I-Firefox Community Forum

Two days ago I closed FF and went to bed. I opened it the next morning and lost about 20 tabs. Ever since then, every time I restart FF, I lose all tabs except for one default tab.

TLDR: 1. "restore previous session" is not available. 2. Toggling Settings/Home and Startup does nothing. 3. Update? My FF automatically updates. 4. "about:sessionrestore" finds nothing,

1. FF help said I could go into History and click "Restore Previous Session" but that option doesn't exist. All I can do is look at History and see lists for today, yesterday, last 7 days etc.

2. Another advisory suggested Settings, Home and Startup, select "Open previous windows and tabs". but it was already selected. So I switched it off, restarted FF and then switched it back on. I still lose all tabs every time I restart FF.

3. Another advisory suggested, checking for updates. My FF automatically updates.

4. I tried "about:sessionrestore" It returns with the heading: "Sorry. We’re having trouble getting your pages back." Restore session is greyed out and "View previous tabs" produces an empty list. I've tried it a few times now, identical result.

Thanks for any help. Cheers, Andrew

Just started happening a few days ago. On Lifepoints (lifepointspanel.com) , surveys used to be accessible for one to do. Starting a few days ago , that changed and all now come back with "Try a different survey". No changes on my end. Support at the site indicates it is a browser issue. Any clues? Been using FF all along and it is up to date.

My system • Windows 11 on a Dell laptop. • Firefox Version 157, my default browser. • Norton 360 Standard. • Two Firefox profiles; the warning appears in both. • Firefox Troubleshooting Mode does not eliminate the warning https://support.mozilla.org/en-US/kb/sslkeylogfile-warning?utm_source=chatgpt.com

What I have observed The warning appears on Firefox network-error pages, including when the internet is disconnected or I enter an incorrect URL. A particularly reproducible example occurs after I successfully log in to Kotak Net Banking and select Help → Raise a Query. Firefox then displays a connection/privacy warning associated with the embedded page. I do not see the same behaviour in Chrome or Firefox Private Browsing when performing the equivalent Kotak steps. Troubleshooting already completed 1. Norton Safe Web HTTPS scanning was disabled and re-enabled without resolving the issue. 2. QUIC/HTTP3 scanning, WebSocket Protocol Scanning and DNS/DoH scanning were individually tested without resolving it. 3. Firefox Enterprise Policies are inactive. 4. I found no SSLKEYLOGFILE entry in either Windows User Variables or System Variables. 5. Norton and Dell malware scans found no malware. 6. The warning also occurs when I connect through a mobile phone hotspot rather than my usual BSNL connection. Questions for Mozilla's technical contributors 1. Does this warning establish that Firefox detects SSLKEYLOGFILE, or could another mechanism produce the same message? 2. Can the variable be inherited by Firefox from a parent process or injected into its running process even when it is absent from the Windows User and System Variables? 3. What is the safest way to identify which process or security product is setting it on Windows 11? 4. Is there a known interaction between Firefox 157 and Norton 360 Standard that could explain this behaviour? 5. What evidence should I collect to distinguish a Norton issue from a Firefox issue without disabling security protections or modifying Windows settings? I am not looking to disable security features indiscriminately. I want to identify the actual cause and, if Norton is responsible, determine the precise setting that needs attention. I would particularly appreciate a response from a contributor with Windows networking, Firefox TLS or security-software diagnostic experience. Thank you.

From one day to another the website I use stopped working and can't figure out why. I can access the website from Microsoft Edge so I know it's not the website. I pressed F12 and got this info:

I am not computer savy so I have no idea how to fix this. Please help.

Became aware of Firefox PDF's this week and made the change to my defaults. However, when all the pdf's on my desktop changed, they became miniscule and looks ridiculous. How can I fix? Thank you.

On my Firefox Home Page, I selected two rows of PINNED shortcuts. Each time I open a webpage that webpage is added not only to the two selected rows of shortcuts, but "keeps" EVERY webpage selected after filling the two selected shortcut rows. It is not only annoying and inconvenient, but s l o w s work time to a crawl around these shortcuts ... few, if any, are helpful. If I want to re-entry an UNPINNED shortcuts, I go to history and select the one I want. WHEN is Fire Fox to solve this seemingly simple but annoying problem?

For the last year, I have been unable to receive incoming emails from Sutter Health and I have been unable to get my written messages to Sutter Health to send. Have I caused something in the Firefox browser to block the site sutterhealth.com or mho.com? If this message is not something Firefox can help me with, can you reply so I might search out who might be able to assist me. Thank you, in advance, to your potential help in this regard.
