Firefox Community Forum

I've been using Firefox on Linux since it was Nautilus. Currently running EasyOS Linux Daedalus and Excalibur on different Lenovo ThinkCentre Tiny Core i3-8100t boxes and different drives: A good Samsung SSD and two good flashdrives. 32G new RAM installed on each box. I've been using these boxes for over a year. For the last month or so, ever since updating to v. 146 my tabs have been crashing like crazy! I don't normally have more than 10 tabs open at once. But now, as soon as I open a 5th tab it crashes.

I'm running Top to watch CPU and RAM usage. I see nothing unusual. I've rebooted. Disabled all add-ons and run in Troubleshoot mode. Tabs still crash. My only add-ons are uBlock Origin, Temporary Containers and Dark Mode. It happens whether I have hardware acceleration turned on or off. I don't know what else to try. Here are my most recent crash reports. I hope you can figure out the problem. Thank you so much!

When a system-wide VPN application (not built into Firefox) is enabled, the behavior of the address bar changes: on the first click, it only shows 5 sites (Top Sites), instead of the usual 9. After pressing the Spacebar, the list from browsing history loads normally. The problem persists after turning off the VPN and only disappears after a full restart of Firefox. The issue is reproducible. Firefox version: the latest

Everything is gone, I have had to reinstall windows 4 times in the last week with a new PC and now all my sync data is gone...Chrome remembers everything fine and Mozilla did remember everything until this install and now its not syncing anything.

If this stuff is gone so am I.

Have tried logging in with my google account, tried logging in with Moz account, tried sync button over and over tried restarting, tried uninstalling and reinstalling and manually deleting all the folders STILL NO SYNC DATA AT ALL.......

I won't show my account information but when I try to access Amtrak's Guest Rewards site it goes into a loop. First it asks for username & password and accepts that with no problem. Then it asks for the code it sends to my cell phone and accepts that. And then it just keeps reloading various pages until I kill it. This is the error message shown in the log, it's repeated over and over:

NS_ERROR_ILLEGAL_VALUE: Component returned failure code: 0x80070057 (NS_ERROR_ILLEGAL_VALUE) [nsIFaviconService.replaceFaviconDataFromDataURL]

   loadFavicon resource:///modules/PlacesUIUtils.sys.mjs:220
   loadFavicon resource:///modules/PlacesUIUtils.sys.mjs:647
   setIconFromLink resource:///actors/LinkHandlerParent.sys.mjs:139
   receiveMessage resource:///actors/LinkHandlerParent.sys.mjs:60

I'm running under Mac OS 10.13.6 The site loads fine when I use Safari (version 13.1.2)

Thanks

I tend to have long and extensive conversations on Firefox's Copilot AI but I've run into an issue that makes this more difficult. When I press CTRL + F to search for text through a chat, it only searches on the webpage I have open on the right. I was wondering if there is a feature that exists that does this that I'm not aware of, and if not, maybe that could become a thing later?

Bonjour, Cela fait plusieurs message que je vous adresse mais je n'ai reçu aucune réponse ? Depuis votre dernière mise à jour de Firefox, Je n'ai plus aucun marque page ni Favori. J'ai essayé diverses méthodes en ligne mais rien n'y fait. Pouvez-vous m'aider. Je vous remercie de votre réponse, Cordialement, Patrick BASSELIN p.basselin@gmail.com

In my org - ever since the release of Firefox 146 - each time an update is rolled out on a WIndows 11 endpoint - Firefox is no longer able to launch.

This is resolved by uninstalling and reinstalling the client. We've had no issues with the ESR release in my testing.

What changed? Anyone else experiencing this?

I had our security team take a look at the antivirus - they've confirmed we aren't blocking Firefox and they did not see any block reports.

No relevant policy changes have gone through around the time of the incident. Initially I suspected users were installing Firefox ESR from the Company Portal alongside the standard release - but confirmed this is not the case. Also ruled out browser extensions - error persisted across a config without any extensions.

Please let me know if there is troubleshooting info I can collect. I included info from my own browser, but I reinstalled on the 27th and it has been working since. However, it has broke specifically on the days new releases have come out.

Thank you for any suggestions!

Hello

When I restarted my Windows 10 computer, the activity bar and all my history disappeared.

It was working perfectly this morning.

Any ideas?

This is the second computer in the last two weeks that has done this to me.

Best regards,

Hi, I am using Firefox on Mac Os Tahoe and IOS 18.7 and 26.2 (2 iPads). I have set up synching of my open tabs, but this works only from MacOs to the iPads, not the other way round. When closing MacOs Firefox tabs on the iPads this does not synch back to the Mac. I am missing something?

I am unable to sign in to my yahoo mail account. It gives me a fault that "something went wrong, please try another device". I can use brave as my browser and sign in with no problem but not with firefox. Any idea why?

1. After composing mail in Yahoo mail on my Mac laptop with Firefox, I cannot scroll down to "Send" to send the email I can Send using Safari on the same laptop,.

2. On the Website Sense.com, Firefox has changed the background. The original is baqlck background with yellow text; Firefox displays White background with blue text. Safari displays the original on the same laptop. I've been using Firefox since 2000, please stop tinkering with pages which work. I'd prefer to continue using an Open Source outfit rather than a Proprietary one, in solute of not having a Help phone number. ThANK YOU.
