Diễn đàn hỗ trợ Firefox

All of a sudden for the past few weeks or so, I keep getting the message in the attached screenshot when entering words in the search bar and clicking on Google. This never happened before in all the years I've been doing this, so what's up with it and can it be fixed? Thanks.

I have recently re-installed Firefox version 140.0.2 (64 bit) following a crash and have been reconfiguring it to my requirements. I have the bookmarks drop down menu on the left of my screen but would really like it on the right hand side. I have searched the various on line articles but can only find a solution going back to 2019 which suggests that there is a small arrow next to the word Bookmarks at the top of the menu, but there is no such arrow on my version, only a X, which closes the drop down. I would have attached a screenshot, but the facility doesn't work on the drop down menu. :-)

Am I missing something here please or is this option no longer available?

Regards and TIA

When I try and open Firefox, a window pops up for a millisecond before going off my screen, and firefox doesnt open. This is extremely irritating as i downloaded firefox since I also cant open chrome. Is there a fix to this, I have restarted my computer and have uninstalled and reinstalled firefox.

Thanks, Nathan

Is it possible to view the contents of two tabs simultaneously? I have been in many situations where it would be very helpful to view two different web pages side-by-side to more easily make comparisons. Opening a new window and viewing them side-by-side is similar but being able to pick two tabs to view in one browser would be a lot faster and easier to control.

Before upgrading to Firefox 140, I would always quickly switch between my default DuckDuckGo and alternative search options, like Wikipedia, using the up and down arrows. I would just type the search term in the address bar and then tap the down key a couple of times before pressing enter if I wanted to use a different search engine.

The new address bar no longer seems to offer this option. I see I can still select alternative search engines using the mouse, but pressing the down key no longer lets me select them.

Is it possible to re-enable this way of quickly switching between search engines using the keyboard?

Hi everyone,

I'm on 140.0.2 / Win10

My current about:config:

browser.urlbar.trimHttps false browser.urlbar.trimURLs true browser.urlbar.untrimOnUserInteraction.featureGate false

I noticed the new https trimming, but when I double-click (e.g. to select a word in the URL) to copy or change a part, the https pops back, shifting where my cursor is relative to where it was, which is annoying for having to reposition the cursor.

Disabling `browser.urlbar.trimURLs` should make sense to revert to no-trimming, but it didn't work.

`browser.urlbar.untrimOnUserInteraction.featureGate` being false already shouldn't have caused the issue I described.

Many thanks in advance!

I have the most recent update and have been excited about tab groups, but it's still not working on mine. I thought the update would be available to all as of May 6, 2025. Is this happening to anyone else?

While I am able to log into my Google account in Chrome, I am unable to do so in Firefox after the latest update. Whenever I try, I am redirected to the attached support page, which asks me to delete cookies and cache contents. Deleting those does not help.

Please help!

I am unable to get access to my Gmail accounts. Every time I select a bookmark link to Google email I get server time out error pages. I have looked at Windows 10(64) Firewall settings and I do not find anything blocking Firefox from accessing the internet(Inbound or Outbound Rules) are set to allow. NordVPN is not set to block any program or connection. I have never seen anything block access to Google.com or any related pages within Google. HELP Please!

How do I remove this annoying box?

And before anyone ask that is not visual glitch, I just censor the text it save, because it is saving my recovery code for my Google account 💀

Anyway how to disable that annoying box? And for good

I ran the windows 11 system file checker (sfc/scannow) to fix a font problem I was having. It did say that problems were found and fixed and I do not seem to have that problem any more. After that, i could not access the Settings in Firefox. I uninstalled and reinstalled Firefox and still could not access Settings. I also cannot access any Web sites either by typing them into the address bar or using bookmarks. Both Chrome and MS Edge work.

The page https://support.mozilla.org/en-US/kb/ai-chatbot lacks the list of data shared with the chatbot AI providers. It would be nice to know how it is done, how to review the data, and how pages can provide better data.

I love FF and I appreciate the intentions behind the new update for quick/custom search engines in Firefox 140, but I can't help but notice that the new UI for custom search engines requires the user to manually click on various buttons and does not allow one to navigate the process via keyboard only. (Unless I'm missing something?) Prior to this UI update, I was able to fully navigate the drop-down and select my custom search engine of choice using only my arrow keys and enter key. Now, the "search with XYZ" button that pops up if you type the site name is only selectable if you click on it, and cannot be highlighted with the arrow keys.

I am not personally disabled in a way that prevents me from using my trackpad, but having to stop what I'm typing and go out of my way to click on various UI elements is a real stymie in terms of flow, ease of use, and efficiency. At least for me.

Is there some kind of secret key combo I can use? Or an about:config setting to enable keyboard navigation in custom searches? Is it a bug? Or simply the removal of a feature?

I hope I will be able to use my arrow keys to select my search engine again in the future— Thanks

The AI chatbot is back in my sidebar. I did not opt in to this. I would prefer not to roll back to whichever version of Firefox is before the AI it's-a-feature-not-a-bug got wedged in; what other options do I have for permanently disabling AI?

Going to sidebar settings to hide the AI chatbot does not suffice. Evidence: I did that already, it has been undone, and I cannot now find the toggle in question.

Personally I vote for yanking it out of the main browser altogether, so people have to actively choose to install the AI chatbot add-on. But my question is about actions I can take myself.

Hello, I am suffering from an odd issue when using twitch.tv. In short, when viewing peoples streams, my video feed will usually turn into colorful static (aka "clown vomit"). I suspect that the issue is coming from Firefox, but I can't be certain. I am using a newly-bought laptop and the issue could be caused by a large number of things, theoretically. Here is what I know:

• When viewing on twitch.tv with quality 360p or higher, the video feed will usually (95%) become colorful static within 1 minute or less. When this happens, the video feed does not ever recover until page is refreshed or quality is changed. (I know a bit about video encoding, so this seems extremely odd to me, if it were due to a networking thing that lost some packets, a full-image frame should come alone sooner or later and fix things, but that never seems to happen)
• The video feed is far less likely to become corrupted when viewing at 160p, but can still happen.
• The ads may become corrupted in the same way that the main video feed can.
• When the feed is corrupted, the rest of the Twitch interface (pause/play, volume, quality select) is extremely laggy.
• When the feed is corrupted, if I pause the stream, sometimes the paused corrupted image is not completely stationary! There will be flickering in small portions of the image, looking similar to texture fighting in 3d rendering, flickering between two equally-but-differently corrupted versions of the image
• The issue never appears when using Chrome to watch twitch.tv. This is what makes me think Firefox is the culprit, not Twitch or networking or graphics drivers.
• Disabling my browser addons does not help.
• Private browsing window does not help.
• Clearing my browser cache does not help.
• I have had the issue happen on Youtube exactly once in 2 weeks, not sure if that's related or not, I think it was a normal "lost some network traffic but fixed itself the next time a full frame was received" thing.
• Video live streams on Youtube don't get corrupted the way they do on Twitch.

Can someone please give me advice for how to fix this? Has anyone seen anything like this before? Is there a way for me to get deeper under the hood of either Twitch or Firefox and more closely debug the video stream when it fails?

Hi everyone,

I have been stuck for 3 days now and tried everything to get pass the authentication process.

I want to submit an Add on. On my profile page, 2 step authentication is enabled.

When i click submit new add-on, i am directed to the Enable two-step authentication page anyway. So ok i'll do that:

"Scan authentication code to continue to ⁨Add-ons⁩"

So i use google authenticator. And im able to continue.

Then im presented with "Save backup authentication codes", so i download them and store them.

PROBLEM:

On the next page, in need to "Confirm backup authentication code". ANY code i try, that was given to me in the previous step, doesn't work.

Error: There was a problem confirming your backup authentication code.

• not using caps or whatever
• no spaces in there
• tried all the codes
• tried different browsers
• The time and date are correct on both phone and windows 10

I have NO clue what to do anymore. I can't get passed it. Can someone please advice. (see screenshots)
