Firefox Community Forum

Check https://piunikaweb.com/2026/08/14/firefox-x-images-videos-not-loading/ for details, but basically xTwitter/Melon messed again with their latest update.

Any word from those in the know yet? Having to use different browsers to see multi-pic posts is really annoying.

With every release of Firefox I find that more and more websites that I use become unusable with Firefox, meaning I have to constantly switch between browsers that are not broken, like Chrome and edge. Before abandoning Firefox altogether I would like to know if it is possible to repair Firefox. The latest site Firefox that causes Firefox to crash is thai-language.com, which returns the completely false and meaningless message "The proxy server is refusing connections Firefox can’t connect to the server at www.thai-language.com". This worked well until the latest 'upgrade' or rather 'downgrade' from Firefox.

Since the last few days weather.com will not work with my version of Firefox. I use 115.37.0esr version of Firefox. Since the last few days Weather.com seems like it is loading and displays the page correctly for half a second but as soon as the page appears, it disappears leaving a small message midscreen that says " This page couldn’t load - Reload to try again, or go back."

I tried turning off my adblocker but that made no difference. Anyone got any ideas? I really like weather.com. It's one of those nice websites that are like when the web was new and was just a useful thing for everyone.

recent firefox update can no longer copy and paste when creating a blog post in Squarespace, I have been using squarespace for around 15 years for my websites and I have never seen this issue, Firefox 15.1 installed and all of a sudden when trying to create a blog post in Squarespace, when I right click a text box pop up and it no longer says paste so I can no longer copy and paste text - this is more than a little annoying, you will not be surprised to know that I am now using Chrome to create my posts, there is no issue in chrome. I am a firefox geek! how can i solve this problem, I just did another update from Firefox, the issue remains I have been using computers for 40 year so I am not a novice but software glitches, I am lost

can not copy and past in ebay descriptions when trying to make a listing .Also can not type in the description box will work on edge trying to list but can not as i can put information in description box. Tried on edge works fine. turned off enhanced protection still same.

In during a search this problem has happen before after updates

For whatever reason when on the front page of YouTube, this magenta border will flash on and off around the top header as well as the button elements, I have no idea if this is Firefox or yt, but I've tried everything, on YouTube, I've tried fixing it in troubleshooting, code, accessibility, restarting browser and computer, randomly removing extensions. Nothing is stopping it. It briefly tried doing it on a different site but stopped on it's own, it's only effecting YouTube and Firefox

NEW NOTE; THIS is actually occuring on other websites now, specifically the Mozilla mdn page I looked at to glance and see if I could figure this out myself. So far still can't fix it

Hallo Firefox Community, ich habe seit 2 Wochen das Problem, dass ich mich mit Firefox nicht mehr auf bestimmten Seiten einloggen kann bzw. die Seiten sich bei der Anmeldung nicht mehr laden. Z.B. bei Klarna komme ich nicht mehr in meinen Account. Mein PC läuft mit Win7 Prof. SP1, das letzte Update von Mozilla lautet: Firefox 115.36.0esr (20260514164700) Details Installiert am: 20. Mai 2026 um 13:41:44 Status: Das Update wurde erfolgreich installiert

Hoffe hier hat jemand eine Erklärung dafür. Ich bin auf mein Firefox angewiesen, verwende den Browser schon eine halbe Ewigkeit. Möchte ungern auf einen anderen Browser wechseln.

Danke an alle!

Hello -

I cannot correct misspelled words when using Proton Mail. It has worked in the past, until recently. Perhaps the latest Mozzilla update? In the body of my email Proton email shows the words which are misspelled but I cannot right click to correct the spelling. Proton never seemed to support the "subject" field typos but did support spelling correction in the body of the email. The spelling correction works properly in Google docs.

Spelling correction is turn on in Firefox settings.

- Firefox 151.0.3 (aarch64)

- iOS Tahoe 26.2

I invoke Face Book but it FB page asks me to log in. Will not accept my user and password. Also You Tube is unstable. Only when in Firefox. Other browsers are OK, I can go straight in to site on other browsers.

Lately I am noticing my browser takes a very long time to load certain websites (GitHub and Confluence mainly)

I don't experience the same issue on Google Chrome

When sites do load, they are often without stylesheets, and page elements do not work (possibly indicating scripts are not loading)

Hi,

I'm seeing a strange issue in Firefox when using an online work-hours calculator for payroll calculations.

On this page: https://mauricettecalcul.fr/

When I enter certain hour and minute values and convert them to decimal hours, Firefox occasionally returns a slightly different rounded result compared to Chrome on the same machine. Because these figures are used for payroll, even small rounding differences can be problematic.

I've already tried clearing the cache and testing with extensions disabled, but the behavior remains.

Has anyone experienced browser-specific rounding or calculation differences in Firefox with JavaScript-based calculators? Is there a way to identify whether this is a Firefox issue or something related to how the site handles numeric calculations?

Thanks for any suggestions.

I get an "access denied" message when I do a search within a web site that I am connected to. Problem is with Fire Fox. Do not have the problem with google chrome.

Hi,

I’m facing an issue with my website’s fine checking tool on Mozilla Firefox. My website is evgfinescheck.com , and the tool works fine in some browsers, but on Firefox it doesn’t load properly and sometimes shows an error.

I am already using the latest (updated) version of Firefox, so the issue is not due to an outdated browser. The tool either fails to fetch data or doesn’t respond as expected when users try to check fines.

I’ve checked basic things like internet connection and browser updates, but the problem still persists specifically on Firefox.

Can anyone guide me on:

What could be causing this compatibility issue? Are there any common JavaScript, API, or CORS-related problems specific to Firefox? How can I debug or fix this issue?

Any help would be appreciated. Thanks!
