Diễn đàn hỗ trợ Firefox

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.

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

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.

On my steam deck, from time to time, the firefox's touchscreen support seems to switch modes.

The symptoms are:

- Instead of scrolling, one-finger touch-and-drag now zooms in and out (depending on direction)
- The touchscreen no longer lets me select or close tabs, or focus or click in-page widgets
- This mode-switch is restricted to the firefox window in which it happens
  - Moving the tab to a new window results in the new window working fine
  - Other existing windows are unaffected (although they may later experience a touch mode switch  event)

I have yet to determine what triggers this switch, nor can I figure out how to undo it.

Hi,

Since last week I am unable to properly use some websites that are failing due to CORS requests, but they were working before. Some examples are es.webuy.com or a local Jellyfin instance. After trying to enable/disable some settings that I thought could be related to the problem, like security levels, I ended up creating a new profile. In this new profile everything works, but as soon as I synchronize my Mozilla account, then these websites start failing again with CORS requests errors.

Any idea about what setting might it be the one causing problems? Or any idea about how can I debug/troubleshoot it myself?

Thanks!

This setting, "Always ask you where to save files," is definitely broken.

In a related article, they provided this solution: https://support.mozilla.org/en-US/que.../1534384 https://support.mozilla.org/en-US/questions/1534384]

Proposed solution: "I believe you also need to go into Tools -> Settings -> General and set the Action for the types of downloads (Applications) to Always Ask for those types you want it to."

But this workaround should not be needed. "Always ask" means always ask. As in always. No other additional steps should be needed.

Can you folks please open a bug to get this fixed? This used to work just fine in (much) older versions of Firefox and Netscape. "Always ask" is supposed to mean always ask. Like, always.

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?

I remember in the past being able to disable videos from playing on a page and having a play button I could click to play them manually, am I hallucinating or is this a feature I cannot seem to find ?

I have recently begun to have hard 'hangs' while attempting to view a video on a site I'm already connected to. I've tried to overcome these hangs, but they continue to happen even after firefox has been in use for a short time. I have to restart my computer, since the hang is locking up all control input.

After many years of using Firefox and then trying other browsers I decided to stick with Firefox now, and immediately I encounter a persistent flaw.

Mainly I browse on chess.com, I mention this because there the thing occurs and I can imagine it is quite a 'complicated' website. Stick with me. I administrate clubs and play chess there so open pages regularly, in new tabs, still generally only three simultaneously.

Every 1 in 5 times the page just gets stuck loading. Only parts appear and the little refresh icon up there doesn't show because the X stays (the one to stop loading the page). This is quite annoying. Simply by refreshing it immediately loads properly. But it is ridiculous to keep having to press F5 every couple of minutes before one can get on. As I also used Beta channel on my win11 machine I figured maybe it's that but after several updates it persisted. Now I am using the Normal channel and a Linux Mint OS and exactly the same keeps happening. I have tried a dozen remedies. Like adding an exception to the enhanced tracking in Firefox and several others and nothing fixed this. Does anyone knows how this happens?

And will Mozilla fix this? Or is it completely at the bottom of priorities because it is site specific?

Thanks for any replies (OS most recent Linux Mint Cinnamon. browser version mint-001 1.0 firefox 147.2) (Happened on Windows 11, Firefox Beta as well)

I have been using Google Messages in Firefox for over a year, and have never had any problem until the most recent Firefox update from Linux Mint. Google Messages loads on the tab, and everything seems fine. But when I click on a conversation on the left, it crashes as it's loading the conversation.

All of my software is up to date, i.e., no new software updates are indicated in the system tray (?) on the panel. Firefox info: mint-001 - 1.0 147.0.2 (64-bit)

System info: Linux Technodrome 6.8.0-100-generic #100-Ubuntu SMP PREEMPT_DYNAMIC Tue Jan 13 16:40:06 UTC 2026 x86_64 x86_64 x86_64 GNU/Linux

Hopefully this gets fixed soon, because checking my messages using my PC saves so much time.

Thank you

Hello, If I had to sign into my gmail account in order to download Firefox browser, does that mean that my new tablet (that did not have my gmail identity on it before) is now fully enmeshed with the Google identity, even though I will not use it on this new tablet?

I often hit ^T (control-T) in firefox without meaning to, because I use that chord in other applications a lot. In firefox it opens a new tab, which is almost never what I want. I'd like to suppress that keyboard shortcut. I tried doing it using vimium (unmap <c-t>) but that has no effect.

Thank you, Silvio
