I-Firefox Community Forum

Hello,

I'm encountering a highly frustrating issue with Firefox. Even though the "Open previous windows and tabs" option is checked in my settings, it is completely ignored on startup. Firefox systematically opens to a blank tab or home page.

Here are the key details and what I've already checked:

• The Ctrl + Shift + T shortcut works perfectly: This proves Firefox is saving my session and history; it's only the automatic loading on startup that is being blocked.
• In about:config, the preference browser.startup.page is correctly set to 3.
• My privacy settings are standard: Firefox is set to "Remember history" and the "Clear history when Firefox closes" box is unchecked. I am not in permanent Private Browsing mode.
• The Windows shortcut I use to launch Firefox is clean (no forced URL at the end of the target path).
• I close Firefox cleanly via the menu, and I've verified that no ghost processes are stuck in the Task Manager after closing.

It makes no sense since the parameter is hardcoded but gets bypassed on launch. Is there a specific file (sessionstore or otherwise) that could be corrupted and blocking the automatic load without blocking the manual restore?

Thanks in advance for your help, I'm out of ideas!

Hopefully, this gets you a fast and highly technical answer. Hang in there!

how do I click ok to do this? Double-click the browser.sessionstore.max_tabs_undo preference to display a dialog where you can enter the desired value, which in your case might be 0 and then click OK. I have an HP desktop running windows 11 and have been unable to prevent history from keeping recently closed tabs.

With the latest Firefox 149, the firefox-l10n.js in omni.ja seems to be gone? its normally located in \defaults\preferences\ the file is now completely missing in the omni.ja is it now named differently or is it migrated into another file? normally i edit the file and add for our deployment: pref("network.proxy.type", 0);

Hey,

in new version of Firefox saved on PC value of filter (devtools.netmonitor.requestfilter) in file: prefs.js. How to autoremove this value after closeing browser?

Thanks!

Ctrl + scroll used to zoom exactly 10% (in or out) now with 1 scroll, the page gets zoomed in at least 30% but it's not consistent. right now, I tried CTRL+scroll up and the zoom went up to %133. I'd appreciate your assistance.

ps, IDK if it's related but I just updated Firefox to version 150.0

Thank you

the go back to previous page shortcut is annoying and it kept messing with my work and I want to disable it I use touchpad and accidentally goes back to previous page all the time and sometimes I have to redo my unsaved work because of this. Please disable this arrow in a blue circle thing

It was nice when FF was simple to use....unimcumbered with all the options...like the latest...profiles.

Why? It's getting to be as complicated as E and C..you don't need all those options - that's why I use FF.

Get rid, or allow the user, to pick and choose, and dump the unwanted stuff from cluttering the tool bar and other options. Just a suggestion that can be made to FF any longer. Use to be they'd welcome feedback.
