Firefox 技術支援討論區

Hi,

I'm having a really strange problem.

I'm using Firefox on WIN 11 with my new LG laptop.

When I access a website's drop-down menu, it does not offer me options that I can make a selection.

I know that it's missing the 2 options - because when I try it on other PCs - it works fine. So the behaviour is different (and works) on other computers.

And the stranger thing is; it also does not offer the options when I tried it with Chrome and Edge.

I tried clearing the history and cache - and it still gives the same behaviour.

I called the Tech Support of the website - and they said it's clearly a problem with my specific PC. I would tend to agree with them - because I can access their site without any issues on other PCs.

I can't figure out what's in common amongst the 3 browsers I tried on this LG laptop. The only thing I found in common is this laptop!

Any ideas - any thing I can try next? Really driving me nuts...  :)

Go to this page... https://electronics.howstuffworks.com/prepaid-cell-phones.htm

Click on any of the links embedded in the text, such as _United Press International, TCM Net, Wireless Guide_. No response.…

EDGE and Chrome have no issue with these links.

I use the site Word Hippo (an online thesaurus and Word tools website) regularly but cannot open this site on Firefox. However it opens on Chrome which seems very strange.

2 issues. 1) Have used Firefox for years on Windows 10 on a laptop. For the last 2 months I have had great difficulty signing in to do online banking with Bank of Montreal (BMO). I get a lot of 404 error messages. Clearing the cache and history works occasionally, but not consistently. I do not have this problem when I use Chrome and I do not have this problem with any other site. This is really frustrating and inconvenient because it is so inconsistent and yet so important. 2) For the last month, every time I start Firefox I get a message telling me Firefox was unable to find previous settings and I have to select 'Start new Session' as it seems unable to restore itself otherwise. Any ideas? Thanks in advance.

Several sites I use (Yahoo, American Thinker) and occasionally other random sites won't load when I use your Add-Ons Privacy Badger, and Ublock. I get server can't be reached errors. I use ESET as my security app. Suggestions?

All of a sudden today I am unable to connect to the Microsoft Community https://answers.microsoft.com/en-us/ and to my Microsoft Account https://account.microsoft.com/privacy/. I can connect with Edge but not FF 95.0. It seems according to the MS Forum that I am not the only one with this problem. Please see screenshots of what I and others are getting.

This error shows from all latest version, going back as far as version 52, whenever I click to check out on some shopping websites, like Costa.co.uk and currys.co.uk. For troubleshooting purposes, I copied a portable Firefox setup and added a gift card and filled in my email address on Costa website: https://gifting.costa.co.uk/home/gift-card/thank-you-little-gc.aspx I clicked to check out, but the error page shows instead of allowing me to proceed to payment. Clearing cookies/history, disabling, add-ons/running Firefox in troubleshoot mode, updating to newer Firefox doesn't solve the problem. I tried troubleshoot mode, deleting all add-ons, re-setting all about:config settings to default, but no avail. I tried deleting misc files and folders from Firefox directories and noticed that the problem is caused by: "content-prefs.sqlite" and "prefs.js", but after deleting those files or the profile folder, the error doesn't show on first load, but if I try a second time after clearing history, the error message starts showing again. The site loads next page only if I delete the data folder or use a fresh install with no add-ons/configurations. This didn't used to happen. I spent a lot of time setting up my Firefox so don't want to start over.

How can I solve this issue?

For the past few days I’m unable to login to my Microsoft outlook hotmail. Whenever logging in I would get the message “something went wrong” with “click to refresh”. I’ve tried refreshing the page multiple times, clearing all cookies, restart my old lab top. Still, the same something went wrong messages. Please assist. Thank you.

I keep getting a message that my browser is not updated. I am using Firefox 95 on Windows 10. Both should be compatible. Two of the websites are Yahoo mail and Chase (bank). I have reset the default user agent as the article states (nothing needed to be changed): https://support.mozilla.org/en-US/kb/how-reset-default-user-agent-firefox.

I also disabled all add-ons, but that did not help. Not sure what to do from here. This just recently started (maybe 2-3 months ago).

A site that I use several times every year recently wouldn't open. Response from Firefox is "Access Denied - Certificate issuer not recognized". Also kept getting bumped out of my email account and all my open tabs would close abruptly. The last may have been rectified but I still can't get into the website I want to access.

I've tried different browsers as well so I don't know if it's Mozilla only or my PC. Even if I type in https://www.(pagename).com, it displays as you don't have permission to access http://www.(pagename).com.

I changed nothing on my PC that would cause the problem.

not able to sign in on my account or track packages on FEDEX website. I talked with FEDEX and they say to try another browser and when I do the site works. I have tried taking off enhanced tracking and restarting in safe mode I cleared cookies and all. Is there a fix for this?

Since January 14 2022, my Firefox (and other browsers like Safari & Chrome) can't load certain websites, notably meetup.com and guardian.co.uk.

I've checked with both ISP and Apple support (Macbook Air M1 2020 on Mac OS 12.1). After running tests, both maintain there are no issues with internet connectivity.

I'm aware that Mozilla (as far as Firefox goes) is working on a solution and has offered a workaround. I have tried it and it doesn't work.

Does anyone have any suggestions?

firefox not opening since 2022-01 Cumulative Update for Windows 11 for x64-based Systems (KB5008353). I reloaded Firefox. Google Chrome and Microsoft edge work OK. Task manager shows running but stats never change 0% CPU/0.2MB Memory

Hello,

I have had a few websites not work properly with Firefox and have needed to open my backup browser (Avast Secure Browser) to use those websites.

Right now it is FedEx that comes to mind again as I kept checking for tracking of packages shipped to me since receiving the tracking info. I queries consistently returned the error message "Unfortunately we are unable to retrieve your tracking results at this time. Please try again later."

Thinking maybe the website was having issues or maintenance (and forgetting I had the same issue with FedEx website the last time I tried tracking there in Firefox), I kept "trying again later".

Then I opened my Avast browser and pasted the same url there and, sure enough, received this report on the display:

Travel History Date or Time City & State Status Monday, April 18, 2022 9:47 PM SPARROWS POINT, MD Departed FedEx location Sunday, April 17, 2022 1:49 PM Shipment information sent to FedEx

I have tried disabling the extension NoScript as well as turning off the "Enhanced tracking protection" and allowing permissions for the FedEx site with no improvement.

I copied and pasted the RAW data as well as the text version from the "about:support" page to send you.

Any suggestions to fix this?

Thank you, Keith McNabb

AOP is the extension that "fixes" the issue.

Sometimes a site won't open at all, WFUV. Some sites won't auto log-in. Citi & NY Times.

Safari has no issue with any.

Hey All,

I'm having an issue where the text in a table, which is supposed to remain within the borders of a given cell, is spilling outside of the cell. It's making the text from different cells bleed into other cells, and makes it very tough to read from said table. I have attached an image to better illustrate when I'm describing. I have attempted to play with some of the text settings, but it didn't seem to make a difference. Thanks for any help anyone can provide!

Cheers,

Walmart website no longer works properly with latest Firefox 96.0.2 64-bit. It works properly with Chrome and other browsers. You can log onto the site and search for products but when you try to add a product to the cart nothing happens. You also can't actually go to the cart. Last time I used Walmart was a few weeks ago and everything worked fine!

I have searched for this problem, and only come across outdated information about Youtube's intentional changes to slowdown Edge and Firefox in 2019. This is not that.

When I load a new youtube video, the video will buffer as normal, and then buffering stops. Then there is a delay of about 10 seconds. You can see from my screenshot that the buffer is filled just fine, and playback begins about 10 seconds later. This also happens if I skip ahead/back or to any position in the video. This firefox install is on a new install of Windows 11, with a new xps 13. The previous xps 13 with windows 11 didn't have this problem, and I don't have this problem on my desktop setup with windows 10.

I use a few addons: decentraleyes, ublock, duckduckgo and I have privacy protections set to strict. I have tried a few troubleshooting steps and the problem persists. Things I have tried:

• safe-mode
• fresh install
• installed additional codecs
• used user-agent workarounds to show as a chromium based browser
• turned off hardware acceleration

The problem doesn't happen on chrome, but it does happen on Edge, which is strange. Because of this, I'm wondering if there is something going on with codecs. In the firefox screenshot posted, the codec used is vp09, same with Edge. But in Chrome the codec is av01.

i have use firefox for many years now. in the last 10 days i have been unable to access my sky casino account but can still get in using using microsoft edge, why? is there a phone number to question this to somebody?

I cannot turn on the audio input and the audio output in Discord web application when running Firefox for desktop PC. The advice from Mozilla Support knowledge base regarding how to enable microphone did not help, since there is always no access request from discord.com detected in "Preferences" -> "Privacy & Security" -> "Permissions".

I am using the latest version of Firefox (94.0.1) on Windows 7 SP 1 and Windows 10 20H2. In Discord Support knowledge base the app is claimed to support Firefox version 80+.
