Diễn đàn hỗ trợ Firefox

Hi everyone,

I’ve recently started playing Krunker.io (a browser-based FPS game), but I’m facing a lot of lag and stuttering in Firefox. The game runs fine for a few minutes and then randomly starts slowing down — especially during fast action scenes.

I’ve tried the basic stuff like:

Updating Firefox

Using private window mode

Closing other tabs

Enabling hardware acceleration

But the issue still comes back, especially when I play for more than 10–15 minutes. Has anyone else experienced this with browser games on Firefox? Any tweaks or settings you recommend to improve performance?

Thanks in advance! 😊

Greetings...

I am a frequent user of multiple tabs whenever I use Firefox. As a result, the new Tab Groups feature interests me, primarily if it will help my to organize and manage my multiple open tabs. Initially, I have the following specific questions.

Q: Is there a maximum quantity of tabs that a Tab Group can contain?

Q: Is there a maximum quantity of Tab Groups that can be open at the same time?

Q: Does the use of one or more Tab Group negatively affect the performance of my web browser?

Q: Can a Tab Group be bookmarked? (Periodically, I need to bookmark a group of open tabs and I am currently able to do so by selecting all of the tabs then bookmarking them as a set.)

Q: Does the new Tab Groups feature represent a way to reduce the number of open tabs that appear at the top of my web browser - basically, a way for multiple open tabs to occupy a smaller space versus scrolling them across the top of my web browser?

Thank you very much for your feedback! Take care...

firefox did an update this morning when I selected a link on a trusted email. Went as normal but I have lost my homepage. All I have is a blank page where I used to have my most used searches and links. All gone blank page (still have bookmarks drop down) Is this the new look? how can I get my homepage back please? Thanks Stephen

I have my Windows Task Bar set to collapse when the mouse is not over it. When I first open the Firefox browser, I cannot get my Windows Task Bar to pop up when I hover my mouse over the bottom of the screen.

If I reduce the size of the Firefox window and then expand it back to full size the Task Bar will again operate normally by popping up when I hover the mouse over the bottom of the screen and then collapsing again when I move away.

This didn't start happening until after the last couple of updates.

When trying to log onto YouTube on my Windows 11 laptop through Firefox or Edge, I input my name & password then Google says, "Couldn't sign you in. Google couldn't verify this account belongs to you." I was on fine yesterday. I can get on with some other gmail accounts that I have, but my main gmail account only works on Chrome now.

Hello, a locally hosted application has a web interface which tries to send a data (POST request) to a remote resource (which is under my control) yet the web browser (Firefox ESR 128.9.0esr) blocks this resource request saying in a developer console (F12) this:

• NS_ERROR_GENERATE_FAILURE(NS_ERROR_MODULE_SECURITY, MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT)

• Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://myRemoteServerIP/request.php. (Reason: CORS request did not succeed). Status code: (null).

I suspect that the CORS blocking is a result of the first (SSL) error, AI also told me that I can configure my remote server/resource (e.g., using Apache, Nginx, or PHP) to include the necessary CORS headers in its responses and indeed the remote server of mine has such lines inside a PHP script that is receiving the request: header('Access-Control-Allow-Origin: *'); header('Access-Control-Allow-Methods: POST'); header('Access-Control-Allow-Headers: *');

The remote resource (server) is using self-signed SSL certificate and it is referenced using IP instead of a domain name.

When I try to do the same request via Private browsing window (without extensions), there is no NS_ERROR about self-signed cert. but only CORS one. When I try browser Librewolf 137.0.2-1 (my FF version is older: 128.9.0), the request is NOT blocked, is OK..

My main aim is not to avoid blocking in my browser, but in all main browsers for everyone.

Is it so that this kind of blocking is default behavior in browsers? Is there please any way to avoid that, beside getting a domain name and CA signed SSL certificate?

bold textUnited.com after login keeps recycling on Firefox

even after we input all info, and it opens up a few seconds later, closes and asks again for login or simply it keeps on going in and out

I'm not sure what category this is under, but there used to be a side window that would come up for me when I would be shopping on Amazon which would check the ratings of the product and let me know by a letter grade whether or not the ratings are reliable. That side window no longer shows up after this latest update. How can I get that back? It was very useful in helping me decide which product to chose!

I have used Firefox for many years and been most satisfied. However, for the last several days when I click to load one of my bookmarked You Tube pages, I get a blank screen except for a shaded 3-line menu and three circles, none of which are responsive. If I click to the home You Tube page I get a shaded outline of the videos but no images and the shaded spots do not respond.

I have cleared cookies and site data and temporary files several times, which will allow me access to ONE You Tube channel, but if I click to another, the same blank screen appears and I cannot return to my accessed channel, it also has blanked out.

Quite puzzled about this, every other site I frequent works perfectly well on Firefox, but You Tube does not. However, You Tube works PERFECTLY WELL on Microsoft Edge and, I suspect, other browsers, so I do not think it is a problem on their end.

Please advise what the next step(s) should be.

I have been using Firefox desktop for over 15 years. However, I frequently encounter websites which do not run well on Firefox. Recent examples I remember are Virgin Atlantic, and Holiday Autos. My bank website is another relevant example. I have to switch to Chrome, which does not have this problem. Considering that Firefox releases updates rather frequently I'm surprised this has not been addressed.

I made the mistake of clicking a YouTube link via Twitter and now Youtube is convinced my Firefox on my desktop PC is a mobile device. Every tip I see tells me to "just request the desktop version of the site!"; only, that's ONLY a feature in the mobile Firefox app... which I'm NOT using. Every time I go to Youtube's home page: it starts me scrolled down as though it's trying to display on a portrait-mode screen, and only shows 3 videos per row. It's clearly trying to display on a mobile device. If I hold down F5, and force it to refresh for a dozen or so times, for a split second it will display properly before re-setting to mobile mode.

Things I've already done so don't suggest them: - Force refresh teh page - Alreadyd one, didn't work - Clear Website cookies & site data - Already done, didn't work - Restart Firefox - Already done, didn't work - Clear browser cache - Already done, didn't work - Open new private window - Already done, didn't work - Restart Firefox in safe mode - Already done, didn't work - Restore default Firefox theme - Already done, didn't work

The problem apepars to be that Youtube has just reclassified my browser/device as mobile and there's nothing I can do to change it.

Firefox should have a button to activate detectportal.firefox.com function as it continually communicates to the network even though it is not required. By placing a button it can be activated when needed.

I have a folder called Old Firefox Data on the my desktop on a Mac. When I delete it I cannot empty from the Recycle Bin. If I try it just comes back. How can I remove? I have uninstalled Firefox and restarted and it still persists.
