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!

Hi! I recently had to reinstall Firefox. Logged into the same Mozilla account I've been using for several years, with pretty much the same config files I've been using since I switched to Linux, and suddenly--for the first time in at least a year--Firefox has (again) started trying to "fix" searches I put into the address bar that aren't prefaced with a search engine. How do I turn this off? (For example, if I go to the address bar and type in "cats" I get directed to a page like the first attached screenshot. If I type in "@google cats" I get directed to the second attached screenshot...)

I'm pretty sure I've disabled everything in prefs.js that relates to that. Um. Feature? But clearly I haven't been able to disable it yet! So.

FF 147.0.1 (64-bit) Linux mint 22.3

Hi everyone, for some time (~2weeks) I have the issue that I don't get any autofill-information in login screens.

I checked the relevant settings/passwords/"Fill usernames and passwords automatically" (OK) I deleted my ff profile and reinstalled ff. (whereas here it worded briefly) I disabled all plugins (only have "uBlock Origin" running at the moment)

I'm pretty puzzled, does anyone have any ideas? Best, Stefan

I am trying to access my QNAP NAS configuration page within my home LAN from a newly installed Linux PC with Firefox 147.0.1. Firefox won't let me access the page, popping up an error page:

Warning: Potential Security Risk Ahead

Firefox detected a potential security threat and did not continue to nessy.fritz.box. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

I have verified that the claimed risk is nonexistant, but Firefox does not allow me to bypass the warning. There is no "Proceed anyway" or "Advanced..." button as claimed in various help articles.

How can I convince Firefox that I know what I am doing?

NB: The same page is accessible, also with Firefox 147.0.1, from a Windows PC.

Hi Lovely Firefox Developers, Help articles say that "The translation feature ... has been available for all users since Firefox version 118.", but I can't see it and I'm on v147. I don't want to install the add-on as the articles say it's obsolete, but I can't see any other way to get it. Am I missing something? Tim

Since a while, I think it is since I created an extra testprofile with "firefox-esr -P", but I've set my main profile as default again

When opening a link in another program than firefox I get always: a popup "Close Firefox" "Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile."

I do have both firefox and firefox esr, I usually use regular firefox the second came with the debian 13 repository.

I keep the esr to test display issues for reproducibility on my personal desktop, because I manage debian 13 kiosk-style desktops with firefox-esr.

(I noticed also that the regular firefox profiles can not be opened in firefox esr, so I use an extra profile for esr)

So I have two Google accounts, let's call them Antelope and Bear. Antelope is my "main" account, but I use Bear for a lot of things too, which includes Gemini. So, if I want to use the Gemini chatbot option on Firefox's sidebar, it would make the most sense to use it under my Bear account, since that way I can access my previous chats and all that. However, when I open the Gemini chatbot, it automatically logs me in as Antelope. And when I click on the account's profile picture to swap to Bear, it instead opens the Gemini site on a new tab, in which I am indeed logged in as Bear, but the sidebar remains stuck on the Antelope account. I've tried the "reload Gemini" option, restarting Firefox, and clearing the cache, but nothing works. I think I could fix it by logging out of both accounts, then logging in only as Bear, letting the sidebar "grab" that account, and then logging in as Antelope, but I wanted to know if there's an easier/cleaner way to go about it. Thank you in advance.

Hi, 48 hours ago I upgraded firefox 140.5.0(esr) to 140.7.0(esr), and now, 48 hours later, everything suddenly stopped to work and I cannot load pages anymore.

48 hours is the lifetime of my kerberos ticket. After 48 hours firefox should send a new ticket to the applications, but 140.7 doesn't. The ccache in the application is empty!

I downgraded back to 140.5, and immediately everything works again.

Was support for GSSAPI/kerberos/SPNEGO removed between 140.5 and 140.7, and why so? Otherwise, how do I get it to work again?

I cannot sign into Discover Card when I use FireFox. I talked to Discover Card about it. They say the most frequent reason it happens is because Discover Card is not on your safe list. I tried signing in on my other PCs with a Ubuntu OS and their browser Opera works fine on signing me in. Within the last two weeks I installed Mint on two of my PCs. works great except for not being able to sign in to Discover Card. I am not having that problem on any other sites. I doubt if my cache is full as my usage being new OS has been minimal. I just tried signiing in with this PC after installing Mint yesterday. I get the same message

"We're sorry. Your request cannot be completed at this time. We sincerely apologize for this inconvenience and are working to resolve this issue soon."

Discover wants to blame Firefox. Personally I think It has to do within the Mozilla VPN. I say that because I often had the same problem when I used McAfee's VPN. Discover maintains it has nothing to do with VPNs and it is a trust issue.

Eventually I want to replace Ubuntu with Mint. But I cannot until this problem is fixed. Opera is also running a VPN when I sign in so this would support Discover Cards theory about Firefox not having Discover on a safe list. I think they have it wrong though. If your site is blocked you are not on Discover's safe list. I wish we could get a meeting of the two minds instead of me trapped in the middle. Hope this helps.

sir, lately i had problems with syncronizing FIREFOX between two computers. seems one has an "old" version. i cannot "install" new versions; i download, but then, how to "install-activate". then i checked on "entry-passwords"...hélas, i do not understand your explanations... the technical terms.... what is the account for... etc. i am 80 years old, and i guess you, the IT community, can't care less.
