Firefox Community Forum

I am using the latest Fiefox and i have disabled all adons i have tried everything I have changed my Facebook password every time i g try to share something on Firefox get a black box on the bottom right that says something wrong . I have tried to copy the entire hing but can not i got some of it I have even reinstalled firebox ans still can not share anything I have tried contacting Facebook but that does not happen no response i appears to work in Chrome on a noter Facebook account so it is Firefox. i will send you what i could get on the screen shot the part that is missing s the part that says something s wrong

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!

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?

First got a msg box from Firefox that my W10 PC had crashed overnite - and I could report it. My PC was back up & looked normal - but when I accessed Firefox the PC crashed - then I got the above error & blue screen and could do nothing on the PC! I restarted again - as long as I DO NOT START FIREFOX - my PC is fine. Help pls! For what it's worth, I happened to open a lot of tabs in Firefox yesterday. Drivers are up-to-date. Vicki

Hi. I'm still new to Firefox and don't really know the settings very well. I recently switched over to using it and realized that when I use most drop down boxes the background of the drop down menu is black, but the text is white and the selection box (when you hover over the item) is also white. Making whatever I'm hovering over very hard to see. I'm wondering if I have a strange setting turned on or not?

Settings wise I have Firefox set to dark mode, not the auto. But when I use the auto it still happens. Trying it in safe mode it still happens. Iv tried to research this a little myself. And read something about the proton setting and turning that from true to false. But this also did not work.

Is there any way to fix this? I just need the text to be a different color or the selection box (when you hover over it) to be a different color.

Attached are two screenshots of what I'm seeing

After my pc has been on for a while, seemingly random duration, Im not able to open firefox anymore. For example if clicking on a link in discord, or if I close the browser and want to open it again. I've tried refreshing and reinstalling but that didn't help.

Since a recent update, whenever I try to go to ufc.om, Firefox shows me the error in the attached image. It used to display ufc.com without issues before the update [ don't remember which update ].

Other browsers [ Chrome and Edge ] display ufc.com without issues.

Firefox has taken to sending pop-ups of breaking news, which I then have to clear manually (Win 10) How can I stop this.

I have looked in settings, but can't find an off switch for this "new" toy. At least the Thunderbird notifications disappear after a few seconds! These just pile up till they block the entire right hand side of my screen - and then they keep going, and block other more important notifications in the main notifications bit.

I usually use Nightly as my default browser in a Windows 11 system. Recently I started to get a new error message showing up when I try to select multiple messages in Yahoo e-mail. I select them by clicking on the first message, then holding down Shift and clicking on the last message in the range. That should turn on the selection boxes for all the messages between the two.

Now, when I press the Shift key, I get an error box right on top of where my mouse cursor is, so it interferes with me. The top of the box says "mail.yahoo.com", which is the web-site I'm signed in on. Then it has a link with the text "Login - Sign in to Yahoo". Below that is an ad for all the wonderful things I can get by signing in to Yahoo. At the bottom is an error message, "We can't generate key points for this webpage."

I tried the same action in the current General Release of Firefox, v140, and this does not happen. I suspect that this is an intrusion by some sort of AI software, but I don't know what setting might have been activated to turn this on. Does anyone have any idea how to turn it off?

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.

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.

There going down like flies chief I have no idea how long they'll last or what the root cause is but I have report numbers listed below: bp-6a2f6577-50b4-4503-aa6f-edc0c0250714 7/14/2025, 5:44 AM bp-cca0da19-acc6-4699-b2fd-f78070250714 7/14/2025, 5:44 AM bp-3afd947d-1ab0-4e44-9fee-f4cbb0250714 7/14/2025, 1:05 AM bp-9399b8e9-a389-41bb-9231-a95d50250714 7/14/2025, 3:54 PM bp-8e2c1005-1c7b-49ea-8a50-dbb780250714 7/14/2025, 3:55 PM bp-d270fbee-4e08-4c3b-a6ce-870400250714 7/14/2025, 3:55 PM bp-1cd7a43d-c702-4a15-bb9f-396ef0250714 7/14/2025, 3:56 PM bp-e6cd9efa-9998-4408-872a-713c60250714 7/14/2025, 3:56 PM bp-23709997-e2af-4463-b1ce-b7a4f0250714 7/14/2025, 3:56 PM bp-d46d3db6-876e-4794-a500-f1a590250714 7/14/2025, 3:56 PM bp-723ea32e-8da6-46c0-bbc2-ea5190250714 7/14/2025, 3:56 PM bp-a8860709-a511-44de-9f6a-318560250714 7/14/2025, 3:56 PM bp-fa8c5f4b-5b15-46d1-8df6-ae76f0250714 7/14/2025, 3:56 PM bp-bc81e502-f570-4e59-86b3-e2d720250714 7/14/2025, 3:56 PM bp-ddfeae99-8833-4297-9d0c-010d20250714 7/14/2025, 3:56 PM

Firefox can't connect to www.123greetings.com but Chrome can.

Hmm. We’re having trouble finding that site.

We can’t connect to the server at www.123greetings.com.

You seriously need to remove the AUTOMATIC tab grouping, it's annoying as hell!

I know there's a workaround, but that's beside the point. You don't break into someones home in order to re-organize it, that's just bad practice all around.

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

All of a sudden Firefox started to use alt+number (e.g. alt+3) to switch to that tab (i.e. tab 3 in my example).

Why? How do I disable this? It prevents me from typing any of the special characters that are located on alt + any number key. E.g. I can type the at-sign, not the dollar, or any such character which requires the alt-modifier and a number.

Hi all, I'm using Firefox 140.0.4 (64-bit) on Debian Trixie and I'm getting a weird behavior with the auto-complete functionality of the address bar.

If I type the first character the address gets auto filled (see 20250711_First-character-auto-fill-working.png attachment), then if I type the second character the auto filled result disappears (see 20250711_Second-character-auto-fill-NOT-working.png).

I've tried any search option combination, but results doesn't change. At the moment I'm using for the address bar just "Browsing history" (see 20250711_Address-bar-settings.png).

The correct behavior would be, as in the past, that new characters confirming the address would leave things as they are. Do you have any suggestion on how to restore the original behavior?

Many thanks,

Raoul
