I had an unusual system crash, and when I restarted Firefox, the History > Restore Previous Session feature was grayed out. Due to the nature of my work, I had a large quantity of tabs open at the time of the crash (please don't judge). I then backed up the contents of the \Library\Application Support\Firefox\Profiles\[session].default\sessionstore-backups\ folder, but unfortunately not the full Profiles folder content. The file recovery.baklz4 does seem to contain my open session info (I can see a recent link in it). Based on web advice, I then tried restarting Firefox, but that didn't solve my issue. I also tried copying in sessionstore-backups files, without success. I then tried the "Session History Scrounger" web application to try and recover links from the contents of recovery.baklz4 because that worked for me in a prior crash years ago, but it doesn't seem to work properly anymore (it only retrieved 4 web pages). Appreciate any guidance as to how I can use my backed up sessionstore-backup files to re-enable Restore Previous Session, or alternatively to scrounge the links that were open at the time of the crash. Greatly appreciate your help! (Please do not suggest using "Show All History"... I have no plans to sort through a dump truck of rice with a pair of tweezers.)

Hello. I added some controls like zoom control to firefox toolbar and it's work while firefox is opened. after closing and re-opening the firefox, those controls will disappear. what's the problem?

Every time I open up my computer something has changed. My favorites in the little boxes are a nightmare. one day they make a new box for everything I have been on that day. well this morning they were all gone except for 1. very disappointed with u

Estoy observando un comportamiento específico en Firefox que no logro reproducir en otros navegadores basados en Chromium.

Escenario de prueba:

Sitio web con un visor panorámico personalizado. Imágenes panorámicas de aproximadamente 4.500 px de ancho. Movimiento horizontal continuo y lento. Sin reproducción de video ni elementos pesados adicionales.

Resultados observados:

En Chrome, Edge, Brave y Opera el desplazamiento es fluido desde el primer instante. En Firefox el desplazamiento comienza con pequeños tirones o saltos visibles. Los tirones disminuyen progresivamente y desaparecen después de aproximadamente 4 a 12 segundos, dependiendo de la cantidad de panorámicas activas. Una vez estabilizado, el movimiento es completamente fluido. El comportamiento se reproduce incluso utilizando una sola imagen panorámica. Si existen varias panorámicas, el síntoma vuelve a aparecer cada vez que una nueva imagen entra en pantalla.

Pruebas realizadas:

Se descartó que el problema estuviera relacionado con transiciones entre imágenes. Se descartó que estuviera relacionado con programación o temporizadores. Se probó con una sola imagen activa. Se probó utilizando distintos métodos de desplazamiento. El comportamiento sigue siendo exclusivo de Firefox.

La impresión es que Firefox requiere algunos segundos para estabilizar el renderizado o la decodificación de imágenes panorámicas anchas antes de alcanzar una animación completamente fluida.

¿Existe alguna recomendación específica para animaciones panorámicas continuas de gran ancho en Firefox?

Hello, I recently used Firefox to either open, save, or both screenshots (using windows key) that changed the files to png. Png will not print on the printer I used so I've tried searches online, Mozilla, pc settings, but can't seem to undo, that is restore the screenshot to its original setting*. I have used an app to convert some png back to jpg but that's just one more computer hassle I don't need. *I've thought about restoring all settings to default but I couldn't begin to say what other acceptable changes I might have made.

The PC used to save as jpg or pdf but either one would work.

Yes, I have carefully followed whatever directions were given, pretty sure, anyway. This note is two hours after my first question. And, yes, I am a simple person.

Thank you.

I have installed Firefox's free VPN. It shows in the toolbar, as a grey X and a grey "VPN". When I click that, I receive a series of promising, colorful dialog boxes that ultimately change nothing. I can only click the grey VPN and run through the same cycle again with the same results (opening yet a new tab). I have looked in Extensions and Themes > Manage Your Extensions, and can't find the VPN. How do I turn it on?

My Merrill Lynch sign in password and user name do not appear. Add blockers are turned off and shield is down, cache has been cleared. The problem does not happen in MSFT Edge see attached picture

Running Windows 10 but with extra year of security updates. Several web sites were running very slow or not loading at all. So I tried doing system restore - only went back 3 days but afterward said it had some problems, and link to Firefox did not work. So I did system recovery back to time from which I had just done restore. But I had no link to Firefox so had to download it new. But now I have none of my previous tabs, links, saved passwords,,etc. I'm hoping my previous Firefox is still on my PC and there is a way I can run it.

I'm unable to type in "Notes" for specific transactions on my Credit Union's web site. It used to work fine until several months ago. The entire Credit Union web site won't allow me to add info or type in a box provided by them for such purposes as it did. I have to use the Safari browser (which I hate using) to do so. HELP!!

Firefox 151.0.1 64 bit for Arch Linux I am trying to create a desktop app from a website - the ai is saying if there is no + sign in the url box then try More Tools -> Create Shortcut but there is no Create shortcut there. So how to create a desktop app from a website?

Recently, I've noticed that, when I Google something, and it shows those AI-created drop-down options (highlit on the screenshot), clicking on the drop down arrow does nothing; no error, no "dropping down", nothing.

Good morning. I'm trying to configure my shortcuts on my home screen. Specifically, I want the shortcut button's icon to display the website's favicon, rather than just the default circle with a letter. I set the custom icon field for the button (as an example) to:

https://www.notationtraining.com/favicon.ico

I have verified that this favicon exists and I can load it into a separate firefox tab. However, it won't display in the shortcut button. I've tried restarting and trashing some caches without success.

Where am I going wrong? I'm on FF 151.0.4 for Mac OSX 26.4. Thanks, Eric
