Firefox 技術支援討論區

Hello,

For about a week now, Facebook Messenger on desktop (on my profile page at facebook.com) will fail to load. If I click on "See all in Messenger" it will just load indefinitely and not redirect to the new page with all the messages.

I have not installed any new add-ons and Troubleshoot Mode has the exact same issue. A week ago everything was fine. It this a known issue with the latest update?

Is there something I can do?

Please don't tell me to reset firefox. Burning your house down for a minor inconvenience is not a solution. It's as unprofessional of an advice as all those "reinstall windows" tips for absolutely every singe issue. That's not advice, just lack of knowledge.

I cannot copy and paste from one Google doc into another Google doc in Firefox. But I can in Google Chrome.

I don't know the reason for this. Is it because Google (Chrome & Drive) does not want competition? Is it because this inter-doc copy-and-paste requires code that Mozilla doesn't want to bake into Firefox?

Doing this on windows Firefox running the latest version as of yesterday (Aug 10 2022).

Hi. I have experienced some font encoding problem occurring in the latest version of Firefox, not in previous versions. My system is Mac OS Monterey 12.3.1 and Firefox version 107.0

On some sites the fonts looks totally garbled (see provided screenshots). Disabling "Allow pages to choose their own fonts, instead of my selections above" in Firefox settings fixes the problem, but then all websites I visit displays with default fonts and not as intended. Moreover, I'm a web designer working with the built in web developer tools, and I need to see the correct fonts when developing.

Hoping to get some help with this issue.

Hello all,

For some reason, I can no longer upload or download files, with the pop-up window failing to appear entirely. I can upload folders through, for example, Dropbox or Google Drive, but individual files don't work.

I've reset my browser, uninstalled and reinstalled it, opened it in troubleshooting mode, disabled enhanced tracking protection, but nothing seemed to work. I've tested another browser, and I was able to upload and download files just fine.

Is there anything I can do to fix this? I'm on Ubuntu 22.04 using Firefox 107.0.1.

for the past several days, my youtube thumbnails have been grey boxes. they aren't the standard "no thumbnail :(" grey, instead just a block of grey.

this is not the case for youtube on chrome or on the app. i've tried the following: - restarting firefox (multiple times) - clearing the cache for youtube - reinstalling firefox - restarting my computer - logging out and logging back into my youtube account - using firefox in a private browser

please help.

After upgrading firefox to 110.0, WhatsApp web failed to load. I refreshed the browser also as I found one solution on forums, but after QR code came but failed to load the chat.

Hi,

I've been encountering a strange issue where colors (especially whites) in the video player are super washed out. This only happens when HDR is turned on in windows, and only happens in my Firefox Developer Edition installation (normal firefox works fine). It also doesn't show up in any windows screenshots - the colors revert to normal when I'm in the screenshot GUI. I've attached photos below of a youtube video, the left is firefox DE and right is normal firefox, both in and out of the screenshot GUI so you can see the difference.

I'm on Windows 11, and I'm not sure what caused the issue. I've tried both refreshing and reinstalling firefox DE to no avail. Pretty stumped on this one, and would appreciate any help!

I've been having an issue for a while now where the cloudflare challenges that ask you to click the check mark to "verify your connection is secure" would just endlessly ask me to click the button and never continue. Sometimes it would say to unblock access to challenges.cloudflare.com.

But if I a launch an incognito window I can visit website with the challenge and it won't even ask! I've added all my extensions to run in incognito mode and everything still works, I can visit the websites in incognito just fine. So the one changing variable is incognito vs non-incognito.

I can have two windows open, one incognito and one not, and browse to the same website and the non-incog window will fail but the incog will just go to the site.

I thought incognito was supposed to only affect the session storage? Does it silently change other things to the running environment of the browser (about:config options, slightly different extension configs)?

Anyone know why this small change would suddenly allow cloudflare challenges to work?

I've tried to search and found some other posts about this, but not a ton... leading me to believe there is something wrong.

Issue: Fonts on some sites are too heavy/bold (vs appearing correctly on Chrome/Chromium browsers) Environment: Windows 10 or 11, Firefox stable (currently 105.0.1) Example site: https://www.subaruoutback.org (this is not the only one, just an example) Workaround(s): I can do one of two things... I can either enforce browser fonts globally, which fixes the issue but then also break some sites in other ways or I can use an add-on to let me selectively enforce browser fonts as needed (which is what I am doing).

Screenshots attached, this is my experience on multiple PCs (Windows 10 and 11). One image is from Firefox, one is from Chrome.

On some sites, it isn't a huge deal... maybe just looks bad but is functionally fine. On some sites the issue is more impactful and actually creates readability issues.

Of course I can continue to work around the issue, but ideally I would like to fix it.

I did read that there are some changes site owners can make for font handling, but obviously requesting that sort of thing isn't realistic in a general sense.

Thank you!

I have been having an issue for a week or more and no updates from the browser seems to fix that. The error reads: Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit. This is occuring with a request to RBC banking. The same appears to be true but witrh different language for a request with Desjardins Insurance portal.The second link printed in red is the result after I cleared all cookies from Desjardins site. I can access many other pages within the two sites. RBC I am logged in (In black). Desjardins I am not yet as a user when these errors come up

Hello.

I have been unable to access product pages of a particular site, I believe, since updated to 106. The pages are viewable with Edge. https://www.officeworks.com.au/ The main page and some pages are fine but all product pages returns "Something went wrong". E.g. Office Supplies/Pencils https://www.officeworks.com.au/shop/officeworks/c/office-supplies/pencils?cm_sp=all:menu:office-supplies:::pencils I would like to know if this is Firefox's or the website's fault if so why.

Firefox 106.0.5 Windows 10 19045.2251

Hello,

Ever since upgrading to Firefox 107.0, I'm denied access to select website, some of which are corporate websites such as Nokia and others. The latest occurrence had the following reference no#:

Access Denied You don't have permission to access "http://www.nokia.com/phones/support" on this server.

Reference #18.9cf7df17.1669164130.8b3c1e51

If I employ other browsers like Safari or Brave, I'm able to successfully access both this page and others which are restricted on Firefox. So, what might be causing this to happen? Firefox is my preferred browser, therefore I'd like to find a fix. Any help would be greatly appreciated!

I'm not sure what happened in the latest update, but it broke the Canvas website that I use regularly for classes and homework. I've checked and confirmed that Canvas still works normally on Microsoft edge.

Extensions shouldn't affect the website because Canvas was working normally until the recent Firefox update.

Anyone know how to solve this problem?

Using my PC, I am clicking on this URL: https://schoolgateway.westminster.org.uk/?page_id=7. Firefox responds with "The requested service is temporarily unavailable. It is either overloaded or under maintenance. Please try later." Every time. Using Firefox for Android on my phone: same result. I have tried Troubleshoot Mode on my PC: same result. And yet Safari, Chrome, Edge and Brave all load the web page correctly with no error message.

What am I doing wrong?

So, for awhile now when I go to some sites, the screen suddenly starts flashing, then it jitters and turns some light color (like a light green; not blue screen, not black). If I guess where the "X" is to shut down the tab that has the video, I can end this. Often, like on youtube, I find the problem is some ad video that was playing. The rest of the site is ok. But not always.

One site I wrote down a few days where it happened: https://www.nbcsports.com/philadelphia/eagles/eagles-face-giants-2022-playoff-opener?cid=sm_npd_rsn_phi_fb_mn&fbclid=IwAR3rGUEa0W8fElrzCWANSIUpti9VKlbn0iHyvcFsviajYExo5tcRSyWBJXA

scroll down to video and everything blinks, becomes unuseable

It happens in lots of places, though. It is not per se a YouTube problem or just a problem at NBCSports. I shell out to MS Edge, and it seems to handle everything fine, so I'm assuming at this point it is a browser issue.

One last point: after this happen the screen display is degraded even after I manage to shut down the offending tab or video. It takes a Log off/log back in or reboot to fix everything. The degradation takes the form of making the screen look a bit like a pointilist painting, although that's an exaggeration.

FF 109.0.1 64 bit Windows 11 NVidia GeFORCE RTX 3060 running studio driver 526.98 (I have switched periodically from / to their gaming driver, which doesn't seem to matter)

Any help, appreciated.

Hello, This issue might or might not be related to [other issue] I have since I updated Ubuntu 20.04 to 22.04 and therefore updated my Firefox to 104. I can't login anymore on Letterboxd since the update. It's not a problem of username or password. When I click "Sign in", nothing happens except a page refresh, but I'm still not logged in. Other strange behaviour on that site since the update: most of the images don't appear. For example on this page : https://letterboxd.com/films/# all the movie covers are just blank.

The website does work properly when using Firefox in private mode though (both login and images work fine), so this makes me think it's related to my other issue mentioned above.

OS: Ubuntu 22.04 Firefox 104.0.2

EDIT after posting this question: I just found out that I can't login on Google either. I enter my username, password, then it asks me to validate on another apparel that it's really me, which I do, and nothing happens so I can't login. It works normally in private mode.

This site, Costco Instacart, worked perfectly with Firefox as recently as April 15, 2023 but today fails (see attached image): https://sameday.costco.com/store/costco/storefront?zipcode=11021

Cloudflare believes it is protecting itself from online attacks when accessed by Firefox. The same site worked perfectly today, on the same computer, using Google Chrome.

Cloudflare is a major CDN and many important commercial sites, like Costco Instacart, have their content delivered by Cloudflare so this is a major issue with Firefox. For the moment there is a work-around, use Chrome instead, but it would be better to have Firefox address issues with Cloudflare.

I have had 2 sites produce this error box in place of the target Web Site (See Picture). I have read previous topics about this and have followed the instructions with no positive results. FYI, clearing the web site's cookies, clearing Cache and disabling Hardware acceleration.

The first was https://www.walmart.com. After leaving a "Feedback" 2 weeks ago it appears as if they were able to fix the problem. However, the site is not as important as my Medicare PPO provider. I tried loading previous versions of Firefox, but that did not help.

In both instances the LOL "support" people's response was to try a different Browser. So, I reluctantly loaded Google Chrome and it worked perfectly. From my perspective, this eliminates everything to do with my machine setup.

Below is the sign-on URL (not unique to me). Please note that this 668 character URL has not changed for over a year. It is just Aetna's adoption of the Imperva Security Firewall. Both my Winders 8.1 and Winders 10 machines produce the identical results.

YouTube is blocking playback on Firefox due to my use of an ad blocker. However, playback is not blocked in the same circumstances when I use Chrome. Are they trying to stop me from using an ad blocker or overturn my browser choice by forcing me to move from Firefox to Chrome for playback with an ad blocker enabled?
