Ok so I usually choose these option to remember history and from time to time delete Browsing & download history and Temporary cached files and pages.

Note: I have "Open previous window and tabs" ticked in general settings which also has a restore previous session option in the history menu. This brings back previous session with tabs etc as is when I close FF. https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-28-08-45-51-cf2daf.png

I thought I could automate this on exit but don't think its working right. So I change the option to "use custom settings for history" and tick all three options:

Remember browsing and download history Remember search and form history Clear history when Firefox closes For "Clear history when Firefox closes" I ticked Browsing & download history and Temporary cached files and pages. https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-06-28-08-45-43-b10213.png

The issue is the restore session option is missing and FF opens with all previous tabs gone. I am frankly not even sure what else is missing such as cookies, site data etc. Is this meant to work like so?

After updated to Firefox 140.0.4 (20250707120347), all site do not load for me, general sites, like youtube/google. There's nothing wrong with my Wifi/Internet Connection, even Microsoft Edge can load the websites.

Firefox recently started "eating" my tabs: closing them without my permission. There are several tabs I want to keep open at all times, because I refer to them from time to time throughout the day, but Firefox closes them from time to time. I googled the issue and the AI directed me to two settings: browser.tabs.unloadOnLowMemory and browser.tabs.min_inactive_duration_before_unload. It suggested setting the first one to "false" and increasing the duration of the second, or setting it to "false." However, the setting will only accept numeric values.

Since I am not having low memory issues, I want Firefox to leave my tabs alone. Is there any way to actually do this? If not, it would be really nice if Firefox developers reversed this intrusive change.

Thank you, Terry

Hey, So I just updated my Mozilla with the latest update and after I restarted my laptop all my bookmarks, history and favourites are gone. I didn't do any backups manually. It's few hundred important work-related links lost. What actually happened? Can I get them back? Please help.

starting just now, firefox will not take me to ANY website. All other browsing services are working. I have tried uninstalling and reinstalling and clearing cache and cookies.

If I cant get this fixed for my job I will go back to chrome and never download or retry this again. I will also never recommend firefox to anyone like I have in the past.

Why does this happen? I was even logged in, and my tab groups are gone. Why??? Do I need to use a different browser? And Firefox has had trouble with some websites where the paying portion is not correct. However, if I go to a different browser (Chrome), the paying portion works correctly. I'm getting kinda tired of these weird things going on. Please don't offer a feature that doesn't work like grouping tabs.

Today: Can't access website. I think it is the ISP or the router. Reset the router. No luck. Tried a different device on the Wifi. Works fine. Tried a different browser. works fine. Shut down Firefox. I had 2 browser instances open with several windows in each. Could not restart firefox, as it did not close correctly. I closed the broken instance(s). opened FF again, only got one set of windows, not both sets. The other instance had a bunch of grouped windows, and the groups seem to be gone. I can recreate most of those, but had some windows with ongoing work and things I wanted to look at and now they are gone.

FF crashed when I tried to get some answer from ediblearrangements.com help.

After every update, Firefox starts to a blank screen and will not start loading the webpage url put in for over twenty minutes to a half hour. During this time other browsers on my Win 10 PC load immediately so it is not a network issue. It is Firefox. When I see that an update is pending I hesitate to do the update because I know I will lose the use of Firefox until it is ready to respond. It just hangs with "loading X.com" showing at the bottom left of the blank screen. I have been using Firefox for a long time and in the past year or longer it has become very unreliable. There are also instances where without an update it will do this and the only way I can get it to work is to clear the cache and the history through settings. What is going on with Firefox! (And lately there is an update every couple fo days!

I reinstalled windows on my pc after syncing all my browser data (bookmarks etc) everything but some bookmarks, i have 4 folders and 2 of them had all that was in there and the other 2 where empty is it possible to get them back somehow?

Hi,

Yesterday I opened Firefox and found that it had completed a factory reset (without asking me) and I have lost all of my data and settings, particularly from plugins (Simple Tab Groups for example). I have a folder called Old Firefox Data on my desktop, and I have copied the files into the profiles folder from about:support, but I have still lost all my settings.

This is extremely frustrating and will take a lot of time to get everything back to how it was. Please let me know how to restore to my old state.

Hi Mozilla Community,

I’ve been experiencing some issues with video playback on Firefox, specifically on YouTube. Videos seem to always play in a choppy manner, no matter the quality settings. I’ve tried clearing the cache and updating Firefox, but the issue persists. I’ve also checked my internet speed, and it's stable, so I'm not sure where the problem lies.

Has anyone else faced this issue? Any suggestions on what might be causing the choppy playback or how to fix it?

To give some context, I was also recently looking at how efficient high-speed trains operate around the world, and came across a fascinating comparison of the top 10 fastest trains in India. Just like video streaming, maintaining high performance and smooth operation is key — it made me realize how even small optimizations in streaming might have a big impact on the experience.

I appreciate any help or insights from the community!

Thank you!

Is there a way to permanently set sorting from A-Z? When I open a file & go to site, I then have to reset sorting within the folder when I go back. Using down arrow sends me to the next folder. Have been Mozilla user for decades but didn't open account until recently. Always set to my default, even on latest PC, in conjunction with other programs. Don't like Microsoft programs.

Guess I probably owe Mozilla a donation but have tight budget, as Sr. on Social Security. Maybe I can contribute a small amount if that would help?? Don't want a subscription. Can't afford it.
