Firefox Support Forum

Updated FF Tuesday evening and noticed first on Wednesday when unable to log in to my Tesco food website. Access not allowed from this server or some such. I tried to use the Tesco feedback form and then got alerts both from Avast (saying it was infected) followed by FF refusal to connect. I tried safe mode and removing and adding FF.exe to Avast without change. I reset FF without change. MS Edge allowed access to all these sites without a murmur.

Today i can get to Tesco main site but still not Feedback.

Also my local Synolgy NAS now has a warning that it is dangerous to access from FF. Nothing has been changed in its set up or security. I can and do override and access everything

Something in the Tuesday update has caused this clash. I did think at one point I also saw 120.0.1 being offered but that may have been my confusion.

Happy user of FF fro many years and do not want to change.

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.

UPDATE: when I use the troubleshooting method, i.e, WHAT HAPPENS is it appears to be trying to work, but it's on again, off again, with more than one extension appearing to be the problem. Very mystifying. The only time the problem is completely fixed appears to be when I close all the extensions. (So far.)

HELP!!!!

When I open YouTube, the search videos all show an image. Then when I select one, for the last two days now, that ("front page) image is gone - although the video plays OK.

When I us my Chrome browser the video I've selected begins playing the instant I open the video; even when I've opened the link in a new tab.

Firefox will not display this site properly https://politicalsignal.com/ -- The site is fine in Edge or Chrome

Since yesterday I can't access multiple websites like Spotify, Reddit, Google Drive etc on my desktop computer anymore. I don't know why and I didn't change anything over night. It also works fine in Microsoft Edge.

Reddit shows the "whoa there, pardner" error, spotify shows 403 error, Google Drive says my browser (Firefox 120.0) isn't supported and others are simply unavailable. At the same time Google looks off and Twitch is just a huge loading screen.

I cleared all the data (cookies/cache), but that didn't help.

I had this reddit error a few weeks ago already, but it disappeared on its own. However it was only reddit that was affected.

I am a 25 year user of firefox and this is the worst it has been 100.0 On more and more sites Firefox fails to work on forms and certain web pages.

forms dont show up forms dont execute once complete certain website actions dont work

my belief is these are special scripts and not the basic website display, but I am having to switch to chrome more and more to acomplish my daily activities.

I have updated recently to 100 and I find it hard to believe I have these problems.

This is the link that Fox was reporting difficulties playing on a Mac running Firefox. I just ran it on my ancient imac using an older LTS version of firefox and am not having any problems (nor with chrome)-

There is one domain that I get a "server not found" error for even after doing many things to fix it including everything here, https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can#firefox:win10:fx119, checking blocked URLs in the registry, running malware checks, safe mode, reinstalling FF after removing all FF folders from my system.

Before I did a completely clean reinstall, disabling the Open H264 codec (see attached screenshot) would allow me to access the site. But thinking it was needed, I did the clean reinstall. Now disabling it does not allow access to the site.

So far, I have not found any other websites with this problem. It's a .edu domain which happens to be the one I work for! What else can I do?

Hi, I'm developing a webapp that's designed for print. It uses a "pinterest style" layout to have a column grid of objects with variable heights, and the print styles avoid breaking these items over the page barrier. (In fact, there are two grids on the page, one after the other). The website looks and works fine on screen, and both screen and print work great on Chromium browsers. But on Firefox, using ctrl+P or developer tools' print view causes the page to hang and the tab to ultimately crash.

I know it has something to do with handling the grid layout CSS as the print preview worked fine until I made the change from a traditional row-grid to a column-grid.

The site creates a variable amount of content based on user options at the top of the page. If the content generated is quite small (avoiding a page break?), the print preview works fine. In the link below, I've included some GET variables to guarantee a long amount of content to reliably reproduce the issue.

The site in question.

Hello. We use Firefox at our work and are having issues with Heartland Payroll. It seems to use Microsoft's cloud and the issue we're having is that it won't send the text message in order for us to verify the browser. It seems to happen on occasion and they try to blame Firefox and tell us to use Chrome. I tried turning off all addons and site tracking protections. That seemed to work on some machines and not on others so I'm not sure if that's doing anything at all. Once the text message is received we can access and use the site like normal but getting the page to send the text verification is where we can get stuck. Thank you for any help you can give.

I have found that Firefox does not play some audio files, for instance on Wikipedia and WaniKani, such as the audio on https://en.wikipedia.org/wiki/Erhu and https://www.wanikani.com/vocabulary/%E9%9F%B3. When inspecting network activity I can see that an attempt is made to load the audio on Wikipedia, but it does not play. On WaniKani however, no attempt is made. (WaniKani uses .webm for sound, maybe that has something to do with it?) The problem appeared after the update to Firefox 118 and persists in private browsing and troubleshooting mode, but does not occur in GNOME Web.

When I use a vpn with firefox (not the firefox vpn), I cannot open normally blocked websites such as twitter or youtube, and instead they open in a sort of half-loaded state (see image). I don't face this problem with other browsers. I have tried deleting and reinstalling firefox, but it doesn't seem to work. Can anyone help out?

the webpage https://app.scoutapp.ai/ doesnt function with your browser. works fine on chrome and brave however but I prefer if it worked with FF. any chance we can get this fixed?

YouTube won't start playing in Firefox. No add-ons enabled. The page is fully loaded, but clicking on Play makes nothing.

The fix is to disable "User recommended performance settings" and then disable "User hardware acceleration when available".

The problem is that hardware acceleration is enabled by default. In Edge or Chrome hardware acceleration is also enabled but it won't break YouTube.

When reader mode (or the standalone readability library) encounters an article on a page where a header has greater content length than the actual article or main content, then the object returned by readability will have members `content` and `textContent` matching the article header and not the actual article. This results in reader mode displaying incorrect content for a given article:

An example Blogger post where readability / reader mode work as expected: https://gnosticesotericstudyworkaids.blogspot.com/2023/11/learning-to-let-go-of-small-details-4902.html

An example Blogger page where readability / reader mode do not correctly return the article's main content: https://gnosticesotericstudyworkaids.blogspot.com/2023/11/really-understand-ego-or-anything-when.html

It appears that the logic in `_grabArtcile` is failing to nominate the actual article content as the most plausible: https://github.com/mozilla/readability/blob/main/Readability.js#L876

Ever since about a week ago, my Firefox just started... bugging. Twitch doesn't work, now Netflix doesn't work, basically anything that plays videos (except for YouTube) doesn't seem to be working.

On Twitch, if a person is live and streaming, upon clicking their stream to view it, it's suddenly offline, even if the chat is going and the "this person is live" notification is there. Netflix gives me a f7351 error. Websites with online media (like free movies on putlocker) have multiple streaming services attached and neither of them works.

I've cleared all cookies, cache, data and history.

This is only concerning Firefox, other web browsers work perfectly.

Extensions on my Firefox are as follows: BetterTTV, Dark Mode, DocsAfterDark, Facebook Container, FrankerFaceZ, I don't care about cookies, Instagram Dark Theme, New XKit, TinEye, Tumblr Saviour. No adblocks, no nothing.

My operating system is Windows 10, 64bit, Firefox is updated to 119.0.1.

Any help would be appreciated as this has been the bane of my existence for a while.

Hi.

When logging into my account at NameSilo, it logs out immediately.

One would think it has to do with their site. But it does not happen with Chrome or Edge.

With Firefox, login happens, then immediately it logs out. Procedure can be repeated ad infinitum.

When simply closing down and reopening the browser, it works, i.e. each second restart it works.

What could be the reason for this predictable problem?

Thank you for your wisdom in advance!

As run into before, i have constant frustration that was motivating me to switch browsers from FireFox where when i open a webpage in FF i am not seeing full content. I use an extension to then open that page in Edge, and i then do see full content.

The most recent example of this is https://www.godaddy.com/help/contact-us where in FireFox the "chat" link did not appear, but in Edge it did. Similar experiences occur when attempting to log into my account at whitepages.com where in logging in FireFox errors out or returns me repeatedly to the login page, yet Edge completes the process without issue. The Whitepages issue has been ongoing for over 6 months.

Thoughts?

Thank you!
