Diễn đàn hỗ trợ Firefox

In HTTPS-Only mode I quite often get a message that the site does not support https but when I Continue the page I land on is a https page. I can't understand what's happening here: does the site have a https page Firefox can't detect or is HTTPS-Only creating the https connection for me, or is it only pretending to be https and there is no real extra security? If someone could enlighten me as to what's happening I'd be most grateful. I have a couple of screenshots to show what I mean, but perhaps you know exactly what I'm talking about anyway! I'd add I can't see anything in the Help articles that seems to deal with this situation, but perhaps I'm just being a bit dense (not unknown!). Hoping you can clarify this for me.

Dzień Dobry,

Na jednym z kont nie wyświetlają mi się wiadomości z poprzedniego roku. Inne konta działają dobrze. Nie wiem gdzie szukać rozwiązania. proszę o poradę.

Pozdrawiam Wojciech

Hello,

While in my internet banking it is not possible to copy/paste the IBAN, the sum or just the name or anything. No matter if I used the context menu copy/paste function or the keyboard shortcuts. I am trying to copy from a Google Drive opened text file or a template saved in my online banking.

In Chrome there was no issue with copy/paste.

Outside of my banking, there are no issues with copy/paste.

I expect it is a security setting somewhere, do you know which one it is?

Thank You!

i had to reset my laptop due to certain reasons ..but i didnt back up things .as i re-downloaded firefox and logged in with my old account ..i didn't get me logg-in passwords for various sites back

Hi

I have been using Firefox for years and never encountered this problem. I changed the theme to dark but it made some websites unreadable, so I changed it back. The problem is some websites did not register the change. I cannot use these websites anymore with your browser, and I would prefer to stay with Firefox. What can I do? I have changed the system settings and Firefox settings. Nothing has helped. I have gone through your troubleshooting advice and googled various topics to figure this out. Nothing. It is frustrating, especially when one of the broken sites is my work portal. This cannot continue, so I will be forced to change browsers. I use both Mac and Windows computers if that helps. It is the same on both.

Cheers, George

Hi, I have been using Firefox for a good few years and I love it. I also use NordPass. Recently I tried to start using Passkeys as they appear to be less hassle, however, when I try to set one up I am told that my browser is not suitable, and it suggests that I use Chrome (or others). Can anyone enlighten me as to why this is?

About a month ago Firefox started giving me BAD REQUEST for URLs generated by the MLS system all of us realtors use.

This URL works fine in Safari, but not in Firefox any longer. What has happened and how/when will this be resolved? JPaul

I am having a significant issue with firefox draining my battery. I used chrome up until the new year and then switched over to firefox from chrome. Overall I love firefox so much more. The format is way more pleasing. I love how it easily signs me back into everything, BUT IT DRAINS MY COMPUTER SO MUCH. Like i used to have an 8hour + battery span my laptop neverrr died. Now I get through MAX 2 hours of full use before needing to charge, and maybe 4 hours just having it at school but not using it.

I thought my dell suddenly started crashing, ran all these tests, and then I realized the only change was that I had started using Firefox... So sad I think I am going to have to leave it.

I read a lot of articles and did everything suggested. my graphics is webreader , i turned on all the suggested features, i have 2 extensions , the only thing I could maybe think of was that I use an animated theme so maybe that was killing the battery, but like if I can't use my theme than whats the point.

why doesn't my theme stay engaged?I have 4 computers and I am constantly having to engage my fav theme on them all all the time.

Theme: Animated Dark fox theme with spinning globe and glow effect.

After the last update, my add-ons overflow menu no longer works from the puzzle icon. It won't expand completely and you can't scroll down, therefore, I can't add or remove add-ons to the bar. See Image.

I'm using this instructions to move my profile from old laptop to new laptop. I've had success with this method in the past, but not today. I copied the files over to my new device, open FF on the new device, and FF just opens as a new installation. What is going wrong?? (I'm going from a Windows 10 laptop to new Windows 11 laptop. (Ugh, I already haaaaaate Windows 11, but that is for another forum!)

I recently traveled to Australia for two weeks. While there, I used my mac laptop (with Firefox as my primary browser) on a mix of both wifi-without-VPN and hotel wifi with a VPN back to my home network activated.

I have been back home for more than a week. Other browsers on the same laptop as well as other devices (like my phone) that I took with me on the trip correctly reflect my location (east coast, USA). However, Firefox stubbornly insists that I am still in Australia. The net effect of this has been to break my access to YouTubeTV, which is not available in Australia.

I have tried: - Logging fully out of my google account on firefox and logging back in (at which point the 2FA prompt on my phone says I'm trying to log back in from Australia) - Deleting all cookies, cache and website data - Fully uninstalling Firefox, including deleting the Firefox folder in ApplicationSupport

None of these have had any effect.

Within YouTubeTV, I can force an update to my location, which will temporarily reflect correctly that I am in the US. But it still won't let me play anything if I'm using Firefox, and within Firefox, will soon revert to location unknown. Other browsers on this laptop, and other devices, work fine.

I am at my wit's end. Please advise.

Starting a few weeks ago, firefox would not load any accounts via https://login.microsoftonline.com/ one one of my Macs.

I was running the latest version 121.xx on MAC 12.7.2

Nothing would fix the site issue, so I tried re-installing and refreshing Firefox. Followed all the troubleshooting steps.

Now firefox is completely broken. Tried creating a new profile. Running in safe mode, etc.

It sometimes will load pages, but extremely slow. But generally is unusable.

Firefox works on my other macs just fine (Profile uses sync with those machines)

Safari and Chrome work perfectly fine. No malware. No ISP issues. No firewall.

Please advise a fix or I guess I will delete everything firefox related.

Hello Mozilla Support,

Since 2 upgrades ago, anytime I try to watch a livestream, my browser slows right down and then crashes.

I don't care why its happening, I just want a definitive fix for the issue.

I'm so aggrieved at this happening constantly, if you cannot provide a firm resolution to this issue, i will simply move to another browser.

I've tried your about:config setting restart to false and other fixes but still keeps happening.

I await your reply.

With Regards,

Mark

Hello, Why does Firefox (121.0.1 (64-bit) macOS 14.2.1 anyways) apply a gradient color overlay to the Business Logos in Google SERPs?

I.e., typically the website's Favicon is pulled or an image written into Schema data to display the company logo next to the search result excerpt. But lately, and apparently only in FF, the logos are discolored by some kind of overlay?

Please see attached comparison between Chrome and FF. Chrome displays the logos unaltered, and FF displays them with this crazy obnoxious overlay/ color correction.

As far as I can tell, this is coming from FF as I don't see it in any other browsers/ devices. Chrome, FF Developer Edition, MS Edge, and Safari do not alter the logo colors.

Is there anyway to request the Mozilla FF stop doing this? I can't possibly begin to imagine how this is helpful in anyway to users... but of course I'm open to hearing any logic behind this decision, if in fact this is coming from FF.

Thank you all for your time and help!

Using a Windows 10 laptop. When I hold down the left touchpad/mouse button and scroll to select a bunch of text, it's fine until it gets to the bottom of the screen, then it slows way down, like maybe one line per second. I tried changing the following values in about:config: - general.smoothScroll.mouseWheel.durationMaxMS to 1000 - mousewheel.enable_pixel_scrolling to false - mousewheel.min_line_scroll_amount to 50

None of them worked. Also not sure if I have to close and reopen Firefox after making a change.
