Firefox 社群討論區

my wife's copy of Firefox picked up a virus. After trying several other things, I saved the profile, uninstalled FF, and installed the latest version. But when I tried starting FF I got an error message: Your Frefox profile cannot be loaded. It may be missing or inaccessible.

For whatever reason, when I open certain websites in Firefox, it shows the prices in UK currency including VAT, but when I open the same websites in Chrome, they show up in US currency. The Windows region setting and the VPN connection is the exact same for both. The difference is the browser.

Is there some setting in Firefox that makes it think I am in the UK, and if so, how do I change that?

Hello,

Since the update I am unable to view pdf within xero and actionstep. These are important programs I require the viewing of the pdf for my employment. Can you let me know if there is a new setting that requires activation or if there has been a change. I have attached an image for you to see that it does not load.

Thank you

Tracy

I've noticed that HDR content on YouTube plays at apparently maximum brightness, which is overwhelming. The same video using Google Chrome behaves as expected. For example:

https://www.youtube.com/watch?v=Xod2xiLA9CM

I'm running FF v135.0 and Chrome v133.0.6943.54. When using Chrome, the video brightness matches system brightness settings on my Macbook Pro (running Sequoia 15.3) but when I use FF, the video itself is incredibly bright, as if the white levels have been maxed out. It seems to be a problem with handling the HDR content. Even stranger, it's as if the browser is able to increase my screen brightness itself, but only in the video pane. I doubt that's actually happening, but that's what appears to happen. If I switch to another tab and then back to the video, it takes a few seconds for the video pane to increase extreme levels.

Also, I tried to take a screenshot of it but the screenshot doesn't show the extreme bright levels that I see when I'm using the browser.

Long story short (as possible):

Windows 11 Home, Firefox version 135.0, File version 18.5.0.0, Product version 18.05

Opened Firefox first thing as soon as PC was turned on today. Immediately prompted for an update. It's Mozilla/Firefox. I didn't question it. I did the update and it asked me to download a file. "I trust Mozilla. OK". It downloaded a Firefox Installer.exe file. The same as the one I installed back in 2022 when I set up this PC. I noticed it was a duplicate because (1) followed the file name. "Odd, but okay...it's Mozilla/Firefox. I trust it"

Then I tried to use Firefox and no matter what website I tried to go to I got a "Gah. Your tab just crashed" on the page. It had "Restore crashed tabs" options but nothing worked. All led back to "Gah. Your tabs..." Thinking about the same Installer.exe file and its (1), I checked the Firefox update history. Nothing for today. I then opened the Properties of the original 2022 Installer.exe and the one today. All were the same except 1) - the 2022 file is 325KB and the (1) file from today is 364KB, and 2) - under Digital Signatures, the Digest algorithm is "sha1" in the 2022 file and "sha256" in the (2) file from today.

I didn't know this Ask a question/forum was here or I would have inquired here first. Instead I turned to Reddit's Firefox group using my phone before I did anything on my PC. I spec'd out the details of the day and was assured by two people to do a restart of Firefox. So I did. Yup, that seemed to fix the issue. And off I went with the stuff I'd originally had in store for my day. Until I had different/unrelated need to view my Downloads and I see a FireFox Installer(2) that must have crept in when I did the restart. There was no notification/prompt or request to allow. It just showed up and I wouldn't have known about it unless I checked my Downloads folder.

Until someone tells me otherwise, I'm staying off Firefox. Two .exe Installer files downloaded for a simple update? One which I authorized/allowed but the other sneaking in when I restarted Firefox? Not to mention the tabs not loading until I did the restart which if legit needed, Firefox didn't prompt me to do? That doesn't sound like normal Mozilla/Firefox behaviour. None of today's events do.

So...is this fishy like I think it is? Fishy or not, what's the best thing to do? I'm okay with computers but DEFINITELY NOT an expert. Hence me being here and asking what to do. Guidance needed. Help?

I wrote out the OS details and specs of the browser. I think that's all that anyone would need but if I'm wrong, don't hesitate to ask for more.

Thanks folks.

I am using the version 115.20.0esr (64-bit) and have noticed I have links in my bookmarks, that are either from other bookmark folders but I never copied them over, or I have new links that I never clicked to be saved? I have deleted those I found but some more keep popping up?

To Whom It May Concern:

I was able to login to ChatGPT before January 30, 2025.

I run Firefox on Windows 10. Currently I am using Firefox 135.0 which seems to be creating problems with Authentication Errors with ChatGPT.

Some extensions I had at the time are:

Firefox Multi-Container Tabs BitDefender Traffic Light AdGuard Terms of Service Didn't Read Print Friendly and MeasureIt.

These are all extensions I actually use.

And prior to January 30, 2025, I did not have a problem.

But ever since then I have not been able to login to ChatGPT due to Authentication Errors. I signed up using my email and password and never use anything else to login.

I am not using a VPN.

I cleared my Cache.

I disabled my Extensions.

I tried to login in a Private Window.

I even refreshed Firefox and it still would not work.

I have contacted ChatGPT's support team and they suggested I try a different browser and Chrome worked.

But I don't want to use Google if I can avoid it.

Please help me with this.

I am sure it will be a cockpit error but whenever I click on a photo sent in messenger when it opens the photo it enlarges it to only show about the top third. Image one is what was sent and image 2 is how it appeared when I opened it.

My Firefox (version up to date) crashes frequently, without any meaningful error message, just "sorry". Sometimes crashed sites cannot be restored. This is particularly aggravating when it happens amidst a working process. I have no clue how to prevent this. Ideas welcome. Thanks to everybody in advance!. Thomas

This is an exact copy of a question with the same title by Steve Ediger, of August 2022, now archived.

Firefox has my credit card information and it shows up in a window when I go to pay for something, but when I click on the credit card I want to pay with, the details appear on the form but get removed almost instantly.

I am in UK. It was working until recently.

None of the earlier answers have helped.

Hi,

I'm having an issue with Firefox (on CachyOS, but i'm pretty sure that is not relevant) when I try to hit domain with PORT number.

To be clear, I have a "service" I am locally hosting on a more widely available "domain.com" (those are examples of course...) I am using this typology to still be able to generate Let's Encrypt certs for domains (that I own) not accessible outside my network for those sub-domains, and am using therefore Pi-hole to serve the few IPs of my few "service123.domain.com"

When I use a Chromium based browser (or FF ESR v128) the only DNS query is for "https://service.domain.com:8000" is "service.domain.com" (as seen on pihole queries and in FF-ESR/Chromium DNS cache), whereas FF 135 there is first a "service.domain.com" (righfully answered by my local DNS), and then a second query "_8000._https.service.domain.com" is sent, but my pihole doesn't seem to recognize (and shouldn't have to interpret anything concerning ports), so it sends it to upstream DNS (which are unable to answer)

I have disabled DoH, and every extensions. So I am really lost on what as changed in FF that would explain this, or if it's a pihole config problem (weirdly only affecting FF 135+ ...)

Feel free to ask anything, I may have omitted important info. Thanks in advance

Within the last few days, I've noticed that Firefox (v135 64bit) quits playing audio from YouTube videos after a few seconds. Audio outside of Firefox works as expected. I've followed the directions to resolving common audio issues, including resetting Firefox, clearing the cache and have disabled all extensions to no avail. Running on Windows 11.

Almost every time I try to log into Bank of America with Firefox desktop, the login is unsuccessful, and the blank login page is displayed again. Again I fill out my User ID and password and press Log In. Usually the same result: the blank log in page reappears, and I try again. Once in a blue moon, the log in is successful, maybe once in 20 attempts. I am using the latest version of Firefox.

I just tried logging in with MS Edge. I successfully logged in on the first try!

How can I resolve the above error message pls when trying to connect to microsoft or outlook An error occurred during a connection to office.microsoft.com. Invalid OCSP signing certificate in OCSP response.

File type-Action settings: For PDFs, the save and ask actions result in a spinning wheel & no other result. Seems to have happened recently, either with latest Firefox or the latest Mac OS update.

As creator of retroonline.net. We recently noticed Firefox have limited value size in IDB which Chrome and Edge do not have. This limitation prevents big games running on Firefox despite Firefox has the best performance on WASM. Will there be a proper way to change this limitation or plan to remove it?
