Firefox 技術支援討論區

I was trying to resolve a graphics issue with Firefox and Webgl2 on a specific website, so I used a recommended solution in advanced settings, which just spread the problem to other websites. I wasn't really sure what to do at this point, so I tried to just reset all the modified settings to attempt to get back to the first download settings. However, I was unable to do this and now Firefox can't load any pages, even when I've deleted the browser and redownloaded it. How can I get a completely fresh download, or even can I? I'm not tech savvy and extremely frustrated at this point.

I need to be able to access banks, specifically USB Direct. I can access my credit union but when I try to get my statement, I get a message that I have been logged out due to inactivity.

When I try to log into the site, the system sends a 2FA code. I enter the code an Firefox goes into a loop waiting for the server. When I use Chrome, I get right in. I do not want to be forced over to Chrome. How can I fix this?

I use photopea.com for photo editing and stuff, but I accidentally clicked on the option to have that site not show a pop-up asking if I'm sure I want to leave the site and asking if I'm sure I want to close a project. Now I can't close projects at all.

Can someone tell me how I can re-enable it for the website?

Hello, I did something stupid. I was trying to set up the dark/light theme via cli, and I asked openai about it.

It suggested this command:

echo 'user_pref("lightweightThemes.selectedThemeID", "firefox-compact-light@mozilla.org");' | jq -s '.[0]' > ~/.mozilla/firefox/*.default-release/prefs.js

Which resulted in the following error:

jq: parse error: Invalid numeric literal at line 1, column 11

When I opened mozilla, my profile was reset, and websites won't load (except this one!). They just hang there loading forever. My internet is fine, chromium works perfectly.

So how do I fix this and is there a way I can recover my profile? (Yes I know I should've made backups)

Hi Guys,

I am using an older OSx version which I am happily using Firefox 78.15 with no issues. Last week I easily attended meetings via Google Meets with no problems to date, until today.

All of a sudden it states that my browser doesnt support it. I have tried all workaround, uninstalled add-ons etc.

Was there a sudden change? This will affact my day to day work if meets no longer works.

Any information please help

Attempting to log-in on Twitch with Firefox Browser - Developer version 122.0b9 (64-bit) is currently not possible, repeated messages are prompted by the Twitch website about "unsupported browser" and to contact browser support to resolve this issue.

Clearing cache, disabling extensions did not work. Using regular Firefox works without issues, only noticed this being an issue after most recent update for Firefox Dev browser.

Side effect as well since update is that any Cloudflare captcha is impossible and all website that use Cloudflare to "authenticate" that I'm human just outright fail or continue indefinitely.

When I attempt to login to my Truist account, I fill in the username and password and hit Sign In. The screen clears my username and password, and I get the attached screenshot. This doesn't happen with other browsers.

Firefox not responding to general websites on the web (Ex: Amazon.com, etc.). I have several Mozilla-recommended security extensions that may be working against my firefox connecting to these general-in-nature websites.

This is on macOS Sonoma 14.1.2.

If I copy/type anything into the address bar, and press enter, it disappears and the browser remains blank. As does: selecting any website from the address bar dropdown, opening any bookmark, or attempting to open any file. There is no error, so I'm at a loss how to debug this.

Firefox was working on Ventura. Repeatable with Firefox versions 120-115, have not gone back further. Neither troubleshoot mode nor deleting/rebooting/reinstalling changes anything.

Uncontrollable reloading of pages - 2 urls in past week - currently: https://www.4wdsupacentre.com.au/ - refresh occurs at varying intervals from not fully loaded (less than 2 seconds) to 10 seconds

Using Mac OS 10.15.7 ; Firefox 120.0 (64 bit)

I have been a loyal Mozilla user for many years and it will be a lot of work to to transfer to chrome or edge but continuing problem with camera/microphone access and now this rubbish makes it necessary.

Sorry, keir douglas

I'm experiencing consistent issues with my website that seem to result in breakages across various browsers. Despite my attempts at troubleshooting, I haven't been able to identify the root cause or find a solution. Here are the details:

Website URL: [Your website URL] Browsers affected: Firefox, Chrome, Safari, etc. Breakage symptoms: Describe specific issues such as broken layout, dysfunctional elements, error messages, or any other visible problems. Steps taken to troubleshoot: List the actions you've already tried to resolve the issue (e.g., clearing cache, disabling extensions, checking console errors). I've ensured that the website is up-to-date and compatible with modern web standards, but the issues persist. Could someone kindly provide guidance on further steps to diagnose and resolve these recurrent website breakages? Any assistance or suggestions would be greatly appreciated. Thank you!

Hi

When I visit the webpages of the Swiss Federal Post Service

    https://www.post.ch/de/kundencenter/onlinedienste

then the scroll bar will not be displayed even though the page is longer than what can be displayed on my screen. As soon as I return to another URL the scroll bar is visible again when needed.

Does anybody know what I can have a scroll bar also for this webpage?

Cheers, Pepe

Hi,

WSJ opinion pages won't load fully on Firefox. The same webpage works on other browsers. This has been a recurring issue ever since I switched over to Firefox. It's the main reason why I still keep Google Chrome around.

I've tried updating to the newest version of Firefox and also iOS. Also, clearing my cache/cookies works sometimes but the problem keeps coming back.

I have a question about the way Firefox browsers behave from a PC to an Android device. I have a simple non responsive HTML CSS website that I have built that looks good on a Windows PC browser but on my Android devices the layout is slightly off. I have tried a few tricks to solve the issue by adding a bit of length to a page so I could space out the text boxes and the links but it didn't help. The best way to describe this is to let you see a couple of snapshots so someone can see the actual issue first-hand. I normally test my websites on two different browsers with the other browser being Chrome. I test both on PC and Android and the issue is only showing up on Android devices. I am a Firefox user but I still test across a few different browsers to see how a website will behave. As mentioned, I only see this issue with Firefox on my Android devices and I have not been able to solve this issue. I would like to ask you if you can advise me on this issue. Thank you, Mike

I'm not sure what happened because it never broke sites like this before. Sometimes it makes a site impossible to read. I haven't done anything to the browser and this just started happening.
