Firefox 技術支援討論區

Hi. Strange request I know because Firefox is working perfectly but Google has failed me.

We have a printer/copier in our small club. The IP address assigned is 192.168.1.125. Typing this into a browser should bring up the copier admin dashboard.

When I do this using Firefox everything works fine, BUT when I use any other browser such as Chrome, Edge or Opera I get the "Cannot connect" "Error connecting" etc message.

I removed Bitdefender antivirus and disabled Windows Defender but it's still the same.

Any network people who can point me in the right place as to where to look or report to the correct forum.

Apologies for posting in here when it's not a FF problem.

Thanks in advance TQO

While this is a Privacy and Security setting issue - at least tangentially - my question isn't about security so much as how this data is being stored/retrieved.

I navigated to an entirely new site the other day and it requested a username and password. When the cursor was in the Username field, a set of proposed entries showed up. These were all (recognizable) first names - not emails. When I checked the Privacy and Security settings, I couldn't find any of the names in stored data. While this may be just cached entries for similar fields ("username" or "name" etc...), the list I saw was heavily curated. One of the names I don't ever recall even entering in any name field (and wouldn't have been used for any login) - but even if I had, the list that I saw was far from exhaustive and would only have been a very specific subset of any data I would have entered into any "name" or "username" field.

Is there somewhere I can find how that list was generated?

Thank you,

Firefox removes the exceptions after every update and they have to be manually re-added. This is a very frustrating user experience. Can you please help me identify if this is an issue with Firefox that can be updated or is it an issue with some setting I have setup.

Exceptions that get reset - Cookies and Site Data, Pop-ups, Add-ons, etc.

Permissions that get reset - All of them Location, Camera, Microphone, etc.

• Side note, the Troubleshooting Information section below has a link to share data, that link does not open in a new window. It opened in this same window, erasing all the content I had typed up the first time.

Hello everyone, a long time ago i changed my youtube name to something else and to this day it never updated on firefox. Yesterday i finally asked youtube support about it and they told me to check with mobile or other browsers and there it works fine, so only firefox is borking out on that one. Do you have an idea how i can solve that?

sincerly, Cammy

Starting with my bank's web site, my user name/password is being challenged. I can't bank. Elsewhere, where my desk top has always been recognized, I'm now forced to log in each time...and I receive an email that a new device has just logged into my account. All of this suspiciously coincides with a recent browser update. On my bank feedback it's showing as Firefox "125"...when all previous logins were recorded as Firefox "124". Help!

I use the Rapport Add-on to protect my personal info especially when doing on-line banking at the moment I have to use Chrome but I would rather stay with Firefox but you dont have this extension why?

Hello. I have put my language everywhere on the settings which is latvian. For possible translations i have only put english. Some pages, for example, whatsapp web is showing in russian ( i mean the app data for sure, not the messages), also some homepages i use open automatically in russian. How can i put latvian by default or if its not available for the homepage, put english automatically?

I want to use the Advanced Preferences (about:config) to select 'Manual proxy configuration' setting. I have been able to set the HTTP Proxy and associated port but I am unable to find the setting in Advanced Preferences that will select Manual proxy configuration. Could someone please help. Thanks

I keep getting this message that pops up in a private window to restart to keep using firefox. Everytime I click restart Firefox, it closes my tabs and opens them again. However, 5 minutes later the window pops up again. Even after repeated attempts of updating, even doing a full restart on the computer, Firefox continues to send this window to me. The private window in the bar says about:restartrequired.

I've tried uninstalling Firefox with a fresh install as well as doing a Refresh of Firefox. Neither seem to solve this problem.

Hi I wish to have Firefox 125.0.2 and 124.02 'separate instances', not different profiles...

I already have 125.0.2 installed with various Profiles.

I found a 'few' links and they were quite 'cloudy' and also since Firefox (now) does not have the 'ask you WHERE to' install... I vaguely remember years ago, it was possible.

I do not mid doing tweaking, I also already have backups of profiles, just in case!

Thank you in advance M

PS it seems Mozilla does not want us to install multiple instances (perception)!

Greetings, I am Alvimutmex. A "not supported" notice shows up each time the Mozilla browser loads a webpage. After looking through the settings, I discovered that Mozilla has to be updated. Could you please help me update Mozilla? For instance, when I attempt to open (https://phoneinsurance.us/), I get an error warning.

I was using Amazon just fine a few days ago. When I tried to open an amazon link yesterday, I got the message: Secure Connection Failed. I tried updating my browser and clearing my cache and cookies. Please fix

I am having the same issues as the person in this thread, but unlike their situation, firefox has not fixed itself out of nowhere. https://support.mozilla.org/en-US/questions/1104044

Everything in the firefox browser looks like it was stretched it out in MSPaint, while my actual OS interface and every other app/software UI looks fine. I have tried simply restarting my computer, as well as every solution in the linked thread, as well as refreshing firefox, and uninstalling/reinstalling, which only served to mess up my shortcuts on the home page. To be clear:

• Hardware acceleration is turned OFF, as suggested in any thread I've found where a resolution issue is addressed.
• setting layout.css.devPixelsPerPx to 1.25 specifically makes it almost legible. Almost. It's still incredibly grainy. Any higher even a small portion of a webpage takes up a ridiculous portion of my screen, rendering it just as unusable.
• In messing around in config, I found that setting gfx.color_management.rendering_intent to 5 helped, in so far as it sharpened things up a little, but it did not FIX the issue. Any value above 5 seems to have zero effect or change.
• Absolutely EVERYTHING else except firefox looks absolutely fine. It is ONLY firefox that is having this issue of all the applications/interfaces on my computer.
• Everything in firefox is affected- images, text, the tabs and address bar, bookmarks bar, absolutely everything.

Every few hours, maybe 4 times a day, XULRunner appears and tabs me out of everything. It says "This profile was last used with a newer version of this application. Please create a new profile."

There isn't a 'create new profile' button. I already made a new profile as well, but it did not fix the problem.

I recently changed to the newest ESR, 115.10.0esr, to fix streaming issues.

Out of nowhere, my cursor speed in Firefox has slowed to a truly unusable crawl. I refreshed a page and it was suddenly inching along at worse than a snail's pace. I'm using a USB trackball mouse. This is only affecting Firefox; no other applications have this issue. Using Windows 10.

Here's what I've tried so far:

• Restart Firefox
• Started Firefox in Safe Mode
• Restart computer
• Create a new profile in Firefox
• Check my mouse's firmware
• Try a different mouse

There was another question about this years ago, but the accepted answer about accidentally enabling a Windows accessibility feature doesn't say which feature it is or how to disable it (if that's indeed the case). The link also seems to redirect to a generic accessibility page.

Recent issue, April 2024. Had version 124 Firefox on Win10 computer and went to Help - > About to have Firefox check for updates. This has worked just fine up until now. The message "Failed to check for updates." is shown in the About screen. I have uninstalled and re-installed Firefox with the same results. Have also un-installed Firefox, un-installed Mozilla Maintenance, then removed Firefox data from App Data folder in user directory, then re-installed with the same results. Also, now when I access a local media server, I keep getting the message "Firefox is installing components needed" and that never goes away. Any ideas?

The RAM usage increases, from 1GB to 40GB+ within a matter of minutes of starting Firefox. I have not added any extensions in months. I turned of several with no improvement. I have 6 tabs opened. Firefox has crashed several times the past couple fo months. I have been away on travel for 2 weeks, and today the problem is much worse.

Firefox (37916) 51GB, Extensions (34308) 370MB, GPU (33072) 298MB , and everything else < 100 MB.

I really love Firefox - use across my 4 devices. Only on my desktop am I seeing this. Laptop, iPad, and Android all work fine. Running Win 11
