Diễn đàn hỗ trợ Firefox

Hello, I am running Firefox on a W10-Pro PC. I always click the lock to check certificate validation. In the last month I keep seeing "Connection verified by a certificate issuer that is not recognized by Mozilla".

When I click for more information I see that "Norton Web/Mail Shield" does not recognize the certificate issuer. When I click on Learn More it takes me to a Firefox site "How to disable the Enterprise Roots preference" I also checked W10 certmgr.msc and I see Norton is listed. Images included below. I would love to resolve this issue. Thank you for your time.

Hi

Reinstalled Win 10 pro on my i7 4th gen 16gb RAM 250 SSD copied firefox profile folder which brings back all my windows tabs bookmarks etc

I now get tabs crashing constantly

Before the reformat I used Norton 360 at mostley default settings for over 6 months with no problems,

tried turning things off in Norton

Norton 360 is reinstalled: browser extensions, password manager, norton homepage, norton safeweb, norton safesearch are all not installed Browser and browser data protection is on, VPN is off turned off auto protect and smartfirewall

use to use adblockplus and privacy badger firefox add ons with no problem these are now off

Ive refreshed startup and cleared startup cache

maybe when I copied the profile across it missed some files however I did zip the old profile folder and copied its a big file 690MB unzipped

not sure what to do now

I see this as a performance problem, and one that I'd hoped would be solved by now, since others brought it up in an Apple Forum.

When using iCloud Notes, the list always used to have empty circles/radio buttons to click on when done. They have all become black squares instead. Apparently this happened, according to a poster, with version 131.0. If so, it is still a problem with version 132.0.2, which I currently have.

Please see https://discussions.apple.com/thread/255794426?sortBy=rank where this appears in the Apple Forum.

My attached image is a portion of my today's list

What?: Using screensharing option in Google meets stuns computer. Where?: Version 132.0.2 (64-bit) macOS 15.1 Steps to reproduce: 1. Open Google meet meeting. 2. Click share screen. 3. Select "Use operating system settings". - this is the only option available 4. Click Allow. Current behaviour: The screensharing feature stuns the computer, showing the loading mouse cursor for ever. I can't select the screen I want to share. The computer is unusable even after quiting Firefox. the computer should be restarted. Desired behaviour: The screensharing works normally.

Hello,

For years I've been able to watch a video in one tab and open a new tab. I could hear the video playing while I opened a new tab. Suddenly today the video pauses as soon as I click away to a NEW tab.

Oddly enough, if I have any other tabs already opened, when I first click on one of those, I can then open a new tab without the video pausing. It's only if I go directly from a YouTube video (that's already playing) that it pauses when trying to open a new tab. Odd.

Why is this happening? and so suddenly? At least I have a work around but this is so weird.

Any ideas out there?

Thanks, Andre'a

BTW - Is "Settings" the best topic? or should I've chosen something else (like Performance)?

Hi! Since lately (can't pinpoint it precisely), I have the following problem: Whenever I click on a mailto url, it opens Thunderbird but inserts the mail with three leading slashes.

These are not present in the url itself and also I don't get them when I right click -> copy mail address. From Gnome Web or Chromium, this does not occur.

I'm on Firefox 132.0 and Fedora 41. If you need more information, I will happily provide them.

Best regards, Carroll

Sometimes, when I copy and paste a Youtube link into Firefox or I open a Youtube video in a new tab, the video player won't load. Sometimes it's fixed when I reload the page, other times it can only be fixed if I open a new Youtube tab and paste the name of the youtube video in.

Notes: - Tested in privacy browser with only Ublock origin active (no other extensions), did not appear to have this problem (It's a bit difficult to test since it only comes up sometimes with opening Youtube in background tabs/copying and pasting a youtube video)

    - Something I noticed: video player appears to load a lot faster in privacy browser.
    - However, turned off all extensions and themes in non-privacy browser and still had the issue
    - Youtube pages load in the background of privacy browser, but in the normal browser I have to click on them to load

- Turned off hardware acceleration, didn't change anything - Tried troubleshoot mode, doesn't look like the issue is still there? But confused on why the issue still happens when I turn all extensions off not in troubleshoot mode

Wondering if it's an about:config issue? I don't think I changed anything in there, though.

Screenshot of my issue below.

I'm running Windows 10 and Firefox with latest updates. With Firefox closed, when I right click on Firefox icon and select Open New Window a previous session window with whatever tabs were open is opened. This happens even if in the previous session I opened a new window, then closed all other windows, and then closed the single tab new window. This seems to have begun happening about 2 or 3 updates ago.

My Google tab won't open anymore in Firefox. I have the latest version. It asks me to restore but nothing happens. I can open google on all other browsers. Safari, Chrome etc. but not Firefox.

FF v132.0.2 (64-bit). We utilize Sharepoint/Microsoft 365, and since switching to Firefox, the zoom controls normally located in the lower righthand corner for Excel spreadsheets is just gone. This is with extensions disabled, even tried Private View. Chrome properly shows it.

Screenshots attached showing Firefox/Chrome. That basically eliminates our ability to use FireFox if that's the case since there's no other way to do it.

This is a hail Mary. Microsoft changed the behavior of Windows, supposedly for security, so that clicking the Firefox button to make it the default web browser is no longer allowed. Instead, I get taken to the default apps section of Settings, where the only choices are Edge and Internet Explorer. No Firefox. Same with images and with video. Microsoft is not helping with this and I'm damned if I'm wading through probably a hundred or so file extensions changing each one individually. Somebody else must have run across this problem and maybe solved it?

I am trying to read the Wall Street Journal online, but I receive the subject message. Not a problem with other browsers. I need a relatively easy fix to continue with Firefox as I am not a sophisticated trouble shooter

I am trying to fix Firefox performance issues. I recently changed to Firefox to escape forced ads on chrome and the lost support for the Ublock origin. But I am having difficulty performing tasks and pages That I used to be able to do on Chrome with no difficulty.

When I open multiple tabs at once the tabs freeze up when trying to load and already opened tabs freeze and anything streaming also freeze. It takes tons of time to load multiple tabs and even sometimes single tabs depending on the website. This never happened with Chrome and I understand Firefox is not as refined as Chrome and is far younger than Chrome is but I feel like it shouldn't be this bad. Is there any settings maybe or maybe settings/preferences in the config area area that might help with faster performance and increased multitasking ability in the Firefox browser?

I have tried

1. Updating Firefox - I am running the most up to date version 2. Updating Graphics Drivers- I am running the most up to date drivers(Updated yesterday 11/17/2024 3. Deleting Cache/History/Logs 4. removed or disables unneeded extensions that I don't use every day and only activate when I need them.

None of this has worked to increase performance.

P.S. I would also like to fix the problem where firefox is using too much RAM if possible.
