Diễn đàn hỗ trợ Firefox

I have been using Firefox on my Huawei P29 for several years. I have Google UK set as my search engine and on my home page and this has been fine for years. Two or three days ago when I loaded Firefox Google UK and Google.com wouldn't display. The link flashes in the top bar but the page stays blank. They will load in Chrome and in Firefox if I have desk top mode switched on, but not in android mode. I have uninstalled and reinstalled Firefox, cleared the browser cache but no change. Getting pretty fed up with wasting my time sorting it out. Is it the Huawei phone or Firefox's last update?

I am unable to login to the DVLC. I get as far as the enter reg number of a car to check it,s been taxed. Then after I input the reg number the next page tell me it is an insecure page. This also happens on my laptop. On both desktop and laptop I am using firefox with duck duck go as an add on. However. In using my mobile with the stand alone duck duck go browser, I can log in and complete the task. This points to a problem with Firefox. Any advice's. This seems to be recent as I have used the laptop and desktop to use the check for a taxed car system ok in the past.

Why am I seeing pop-up windows with ads for this online women's cloting store: https://www.lightinthebox.com

Often, when I go to a website with a store, a website called "coupon2deal" (coupontodeal.com) will pop up. It will be at the beginning of my list of tabs, and it will have a miniature tab with no exit button (I need to right-click it to exit). I believe this may have started after I installed the Honey extension, a similar service, but it has not gone away after uninstalling Honey. I tried blocking the site, but the tab still pops up, just with the website blocked.

Safari is showing the links seen in blue after each line but FireFox is leaving them out. Some type of bug or coding problem. This began happening 3-4 months ago. It used to work fine on FireFox. Would love to stay using FireFox and avoid the Safari thing. Love the browser!!! Mark Miller

Hello!

I can't figure out what setting to fix this: every time I click to open a new window, about 35 tabs automatically open up that I have closed several times in the past. I simply want one new window without any previously opened tabs.

I've tried:

• clearing my entire search history several times
• shutting down Firefox and reopening (which opens up all those tabs)
• uninstalling Firefox and reinstalling it
• initiating the latest Firefox updates
• restarting my computer
• turning my computer on and off
• looking through every single preference in my Firefox settings (I've unchecked anywhere it talks about opening tabs)
• reading various articles on Firefox's support page and on other support websites to try to figure this out (there's little info on this problem; the support is mostly about how to save previously opened tabs

Please help! I'm tired of having to close down all these tabs every single time I have to restart my computer or have to shut down Firefox. It slows down everything I'm trying to do.

Thank you!

Hi,

Occasionally when downloading files on Firefox, they'll freeze completely (often at the very end.) There is no way to pause or cancel the downloads, except to restart Firefox.

When I attempt to restart Firefox, it closes the browser window. However, when I try to reopen it, I get an error message stating that Firefox is running but not responding. The 'Close Firefox' option does nothing, except make the box pop back up a moment later.

I can't kill the Firefox process in Task Manager or Process Explorer, because it says access is denied. I can't kill it using taskkill in command prompt because it says there is no running instance of the task.

The ONLY thing that seems to help is completely restarting the computer, which is getting frustrating to do several times a day.

I can confirm Firefox is up-to-date. Any tips are appreciated, thank you!

There used to be a box to write tags as you can see here: https://support.mozilla.org/en-US/kb/categorizing-bookmarks-make-them-easy-to-find?redirectslug=Bookmark+Tags&redirectlocale=en-US

What happened to it? When it was deleted? Why? Is there a way to restore it?

I am a startup founder. I'm making a webgl rendering engine. I'm doing a stress test with 4 large paragraphs amounting to tens of millions of triangles on a macbook air. Firefox is on the latest version.

When I run the app in chrome/safari/opera, the performance is normal. ~45fps. But in Firefox, it's very slow. My FPS counter (in a requestAnimationFrame loop) says ~45fps on all browsers. But in Firefox, even though the counter says that, the real frame rate is ~3-5fps.

When I try to profile, the problem magically goes away and we're back to ~45fps. I played around with profiler settings, and the key determinant is whether or not I'm taking screenshots. No screenshots = slow. Screenshots = fast.

In the flame graph, in slow mode (no screenshots), it seems like I get stuck in the canvasRenderer and the Renderer mostly waits for it. But in fast mode (with screenshots), the canvasRenderer keeps up and the Renderer spents most it's time in: iokit_user_client_trap

I'm not sure what to do. This is only a problem on Firefox. There's some sort of gpu/threads/something that switches when I profile with screenshots that makes it way faster. This performance hit basically ruins my app for Firefox only. Any idea what I should do?

I closed all my tabs and reopened the browser bc I was getting lag on sites like X.com when typing my messages. Immediately after opening Firefox again, my homepage, MSN.com was loaded. I tried to click on the arrow to scroll through the different headline stories and nothing happened. I used Chrome & Opera to load the same page and they work fine. This seems like a Firefox thing. I have no extensions or permissions that deny me the right to click on anything. What is the problem?

When I sign in to my bank, placing the cursor in the username box produces a number of username options, including the actual unsername and other mistyped ones from previous login efforts. I don’t want any unsername prompts. I went to Passwords in Firefox and made sure to remove the bank as a site to retain and offer such information when signing into that account. I continue to receive these username prompts. This doesn’t happen with other accounts. I cannot track down where that username information resides, how to remove it, and how to prevent Firefox from retaining this username information for this bank account.

I have some Bookmarks on my laptop. I have some of these Bookmarks (Not all) on my tablet, plus some other Bookmarks.

If I sync them, which direction does the sync work in? Will all my Bookmarks on my laptop now appear on my tablet (Which I do not want to happen)? Will all my Bookmarks on my tablet now appear on my laptop (Which I do want)? Will I end up with two copies of most Bookmarks, because all my laptop Bookmarks are transfered to my tablet, plus all my tablet Bookmarks are transfered to my laptop?

I cannot find any explanatioin of what Sync actually does.

Hi,

I experienced at least two times recently that the browser on windows 10 looses all the opened tabs and pinned tabs too. Last time it did also that when I closed the program and it opened itself again immediately without tabs and closed itself down again. Next time I opened the program there was no opened tabs at all again. I have the latest version for windows 10.

What do you suggest me to do?

Thanks for help! Br, Balint

I created an account with chat gpt with my google login. Lately, when I try to log into it using Firefox, after I click the "Continue with Google" button, I am redirected to https://www.arkoselabs.com/ !

After a few tries with the same result, I tried in chrome and had no issues accessing my account.

This one's stumpped me. I'm at a loss. Anyone else having this problem? Is it a redirect virus? Chrome is prone to the yahoo redirect virus. I'm wondering if this is similar or if there's somethin' wrong.

When I moved my data from my old Windows 7 to my new Windows 11 computer, I used a Mozilla account to upload and save my bookmarks. I then transferred my data using a different method.

I would now like to delete my data from this (Mozilla) site but can't find it. Please show me how to clear all my bookmarks, passwords (!!!), everything from this site.

Thanks
