Ondersteuningsforum voor Firefox

Dear Sir/Madam:

I am using Firefox Browser 102.15.1esr (64-bit) on a MacBook Pro Ventura 13.5.2.

I have been using the www.dictionary.com website for a long time, but recently when I attempt to go there, I keep getting the error message as follows:

Unexpected Application Error! FM.findLast is not a function

WM@https://www.dictionary.com/client.e12a2de6.js:36:305976 $o@https://www.dictionary.com/client.e12a2de6.js:1:26519 ka@https://www.dictionary.com/vendor.60d89d9a.js:1:864941 xu@https://www.dictionary.com/vendor.60d89d9a.js:1:921923 bc@https://www.dictionary.com/vendor.60d89d9a.js:1:910907 yc@https://www.dictionary.com/vendor.60d89d9a.js:1:910835 vc@https://www.dictionary.com/vendor.60d89d9a.js:1:910696 ic@https://www.dictionary.com/vendor.60d89d9a.js:1:907503 oc@https://www.dictionary.com/vendor.60d89d9a.js:1:906055 E@https://www.dictionary.com/vendor.60d89d9a.js:1:996565 P@https://www.dictionary.com/vendor.60d89d9a.js:1:997096

I tried clearing caches under Privacy & Security, but the problem persists.

(Meanwhile, I can visit www.dictionary.com on Safari and Google Chrome.)

Could you please let me know what is going on?

Thank you,

Roland

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?

The "font family" property does not change the font of the "option" tag if the font is not installed locally on the computer. I am using Firefox Developer 118 (0b9). Are there any solutions to the problem?

Firefox 117.0.1 (64 bit) Build 20230912013654 Windows 10 Home - Version 22H2 OS build 19045.3448 The link to download my Sears credit card statement in pdf form has disappeared when accessing the website (https://citiretailservices.citibankonline.com) with Firefox. It still appears and works normally when the website is accessed with Chrome. I have the uBlock Origin extension installed on Firefox, but it is disabled on the Sears website. Screencaps attached.

Olá. Já faz um tempo, mas meu web wpp não carrega mais nenhuma figurinha. Alguém conseguiu solucionar isso já? Ela fica como um arquivo de midia por baixar. Minha versão do ff é 117.0.1.

hello? I am currently using Firefox Nightly(Snap 119.0a1) on Ubuntu 23.04. As the title suggests, when the main Firefox window on YouTube goes into the background, the subtitles in the PIP are not updated. 1. Go to YouTube in Firefox nightly, play a video, turn on subtitles and PIP. 2. Open a program other than QT and change it to full screen. 2-1. I just tested it, and it can be reproduced by simply minimizing Firefox. 3. Subtitles are not updated until the main Firefox window (not the PIP window) appears on the screen. 3-1. When I opened the QT program in full screen it worked fine (Firefox may not be aware that the QT program has obscured Firefox). 4. When the Firefox main window appears on the screen using any method such as Alt+Tab or Win key, the PIP subtitles are updated again. 4-1. Even if it is a GTK app, transparency is applied and the subtitles are updated when the Firefox main window is visible in the background. ※ I created a new profile for testing and tested it, and the same problem occurred.

This is a description of the attached photos (1,2,3 in order from left/video capture time is the same video time) 1. Subtitles and video displayed normally in the Firefox window 2. The state in which the Firefox window is displayed on the screen: The subtitles in the PIP window are updated. 3. The Firefox window is hidden or minimized: The subtitles in the PIP window are not updated (the subtitles before minimizing the window are not updated to the next subtitles).

English may be weird because I used Google Translator!

I'm trying to use Microsoft Teams in Firefox because the native app for Linux is abandoned and crashes, and at first sight the app is blocking Firefox on purpose. Buttons to make calls are disabled, stating that audio and video are not supported in my browser, but everything works normally if join to existing calls using e.g. links.

Is it possible to trick Teams to think I'm using Chrome? I found the "User-Agent Switcher and Manager" add-on, but I can't figure out how to possibly use it.

Ok, so this is an odd one.

I gamble with William Hill online using Firefox as my browser.

Every year this same problems happen when the clocks go forward in spring time here in the UK.

So I go on the WH website Sunday (for example) at 11pm and it will show me Mondays football matches. But. At 12am Monday until 1am, the now todays football matches do not appear. Its like the browser can no accept this time period exists because as soon as 1am comes, the matches (for Monday) appear.

So I contacted WH for support. They advised that if I am using Firefox that I should try IE instead. So I did. And guess what? The problem doesn't happen on IE. Mondays matches do exist between 12am and 1am. So it is definitely a firefox issue.

But the issue resolves at the end of October when the clocks go back.

So what is going on here? Any solutions? This has been going on several years.

I am unable to login to my Prescription provider's website (which I do every day). Problem started Sunday and still persists.

I am able to login using Chrome, so I know the website is working properly.

Help - I DO NOT want to use Chrome.

Hi! I was wondering why nearly every single page these days opens to the message :

"400 Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit. Apache Server at canvas.instructure.com Port 80"

Nearly every link I click on a website refuses to open! It has become impossible to do school work on this browser because I can't open any link on my school website, and nearly every website struggles to open except from google. I know the links work because I copy/paste them into Google Chrome and they open immediately. Truth be told I prefer Firefox and would much rather keep using this browser! I also can't find an update for Firefox so I believe my Browser is up to date (and I know my laptop is up to date and virus free). Is there a fix coming soon? Or a setting I can change to be able to open links? Classes start this week and I'm stuck!

Thanks for your help!

I got these errors on my console when I load the page. Everything is correct, but after doing some actions (button clicks or text inputting), the web is crashing, and I get these errors in the console, and it starts infinitely reloading.

I have noticed that when watching video using Firefox (Youtube, Youtube TV, Netflix, Nebula) that randomly, the video will just cut to black and then fade in. Sometimes quickly, sometimes slowly. A hack I found that fixes it is just entering/exiting fullscreen, which seems to "reset" the video player. I do not know what causes this, it just shows up when I am watching things. I have noticed that it seems to show up when a video cuts from a darker scene to a brighter scene, although this is not consistent. I am confident that Firefox is the issue because I have watched videos extensively in Chrome, where it does not show up. This also persists if I connect an external display and mirror or extend my screen to it.

I am using a 2023 Apple MacBook Pro 14", with the M2 Pro SoC. My OS is macOS Ventura 13.5.1 .

I have tried solutions that involve messing with the gfx.color-management settings in the about:config page. I also have hardware acceleration turned off, if that is possibly the cause.

Does anyone have any clue as to what causes this?

I use Firefox on a PC to access Facebook (website, not app). This week the Messenger/Chat feature stopped working. I click the icon and it opens but nothing appears in the box, it just hangs. There is an option to open in its own window, but that also is blank - no past messages, no contact names, no ability to start new message. When I log onto Facebook in Edge, Messenger works fine in Facebook.

I've tried everything I found on the internet for this issue - updated and refreshed Firefox, cleared history/cache/cookies/site data, uninstalled and reinstalled Messenger, refreshed Facebook to initial settings, used Firefox in troubleshooting mode, reset everything, turned off browser, turned off my computer, used shift key to reload tab - nothing has worked. There are some instructions about stuck cookies, but I didn't understand them so I didn't try that one thing. I've gone into every menu I can find to try to figure out this issue, which isn't the end of the world, but I would appreciate some other ideas for what is suddenly causing this. Because now I have to redo all of my settings and preferences and logins and the problem still isn't fixed.

Dear Firefox Support,

as an Manager Service Provider I use Firefox on a daily basis to access our management platforms. Just recently one of our providers launched an new platform to submit supporttickets, get information and sorts.

The issue I am facing is the following:

• start Firefox in Normal Mode
• login URL is https://me.n-able.com/s/sso-login
• upon entering my credentials and 2FA (which are 100% correct) I am presented with an error from SalesForce stating 'We can’t log you in because of an authentication error.'

When I start Firefox in either Incognito Mode or Troubleshoot Mode and following exactly the same process there is no issue all.

Of course I checked add-ons and extensions:

• between Normal and Incognito there is no difference
• between Normal and Troubleshoot I so no differences also

Please advise

Firefox keeps getting worse and doesn't work correctly on more and more websites. Every time Firefox fails I switch to a Chrome-based browser and the website works properly. Although not limited to handling of document downloads (banks, credit cards), printing a website's page (File, Print frequently results in a blank page, and/or missing text or images or both, whereas with a Chrome based browser the page prints properly 95% of the time) and possibly to pop-ups (which seem to be blocked without notice). This has been getting worse for many months. About 20-30% of the regular websites i visit are marked as "Chrome only" because they don't work fully with Firefox. These tend to be banks, credit card companies, online stores. I used to complain to companies that their websites don't work with Firefox, but its clear that they don't care, and I now realize that the real problem is that Firefox doesn't care. One website I spoke to (which wouldn't print in Firefox or Chrome) apologized for not setting the website up properly for printing. My guess is that many websites never test with Firefox because most of their customers use Chrome based browsers. For all its flaws, I would rather use Firefox than Chrome-based, but Firefox keeps making it harder to justify that view. When it comes to just looking at websites, Firefox is usually very good, but beyond basic viewing, Firefox is losing ground to most other browsers. I know there are no specifics here, and i think it unlikely anybody will take this seriously.
