Firefox Community Forum

Just enquiring if anyone else is experiencing problems upload things through Firefox Nightly. I first noticed it around a week ago. I was using ChatGPT and uploading images, drag and drop, and I could get one or two to work, after that, the uploading buffer wheel would freeze. Completley clearing the cache would fox the issue, but it would reappear after one or two uploads again. Same issue, uploading to Grok. Today I tried uploading a couple of images to the The Movie Database, and again, same issue. If I switch to Chrome, no problems. If I use Edge, No problems. Funnily enough, when the issue presented today and I tried to post here, I got locked on the Fastly Client Challenge and had to use Chrome to post here. (I don't know if thats related, but squirrely either way) I have reported the issue on Bugzilla, but just wanted to know if anyone else has this issue. Thanks in Advance. Oz.

Over the past week or so, I've been finding that Youtube videos don't start from the very beginning - the very opening is missing.

So as examples, you're playing a song that you know starts directly on a beat, but that first beat gets missed, or there will be an opening sentence such as "Everybody is talking about the latest... " and what you hear is more like "Vrybody" - you can clearly hear that It's slightly off.

This relates to Firefox in three ways.

My initial thought was that there is some conflict with using an Adblocker (uBlock in my case) as Youtube is trying to force a pre-video ad that won't play, but even with the adblocker disabled the problem persists.

I then cleared my Firefox Youtube history so it loads as a completely fresh version - but the problem is still there.

Finally, I tried the same video on Chrome to see if this is definitely a Youtube issue...and it plays correctly without a problem.

Therefore, the problem seems confined to Firefox but I am unsure where - what setting needs to get tweaked to sort this out?

after last update stop working .if I use ctrl v it will paste in. When i try using the mouse it doesn't have paste in the block that pops up.

I can click and paste in the condition box but not the description box.

If I use edge it works. I don't want to use edge

I have also cleared cookies and cache

Firefox 152.0, latest Windows 11 25H2 update on HP TP01-1036. I have tried just about all the AI fix suggestions but nothing works to fix the following problem:

When viewing the Yahoo.com News page, I scroll vertically down to see each article...one after the other. When I come to an article I want to read, I left click it. The article opens within the present tab and is closed by clicking the red "X " at the upper right hand corner of the article; which in turn, returns me to were I was before opening the article. However, eventually, after a few articles are read, when closing an article, the cursor will jump back to the page's first article instead of bringing me back to where I left off on vertical arrangement of the news articles'? This has been happening for around the last one to two weeks. Nothing else seems to be out of wack.

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.

If I upload a jpg image via the + in the Gemini prompt it fails with an ! or doesn't give the (up pointing arrow) execute option prompt. Do usual things and even clean installed Firefox. Same on 3 windows 11 PCs 2 of which not my own hence not configured the same. All did work until latest updates. No browser extensions antivirus temporarily turned off. Same in, private and safe mode. All work fine on Chrome or Edge (sorry to swear at you) A work around is to load them via Google Drive or Photo and pull them from Google platform.

Starting on June 9 2026 my Rockland Trust banking website will not open also other bank websites not opening or take several minutes to open, also other websites not opening. All these websites opened before June 9 2026. I have done all the recommended steps even uninstalling an reinstalling Firefox. What did Firefox do, as I had made no changes. I can open all these websites on other browsers, Google Chrome, Microsoft Edge, etc. I want to keep using Firefox but I can't if websites won't open. Clare O'Brien

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!

Unable to upload any images to Gemini. Working fine on all other browsers. Images always fail unless security levels set at lowest. When the do upload the action button does not become active

Content Security policy blocks essential scripts no matter what I do.

It's new Firefox installation, Troubleshoot mode, Enhanced tracking disabled, I'm not on VPN, can log into X.com in another browser just fine.

It's the reason #1 I don't use Firefox. I thought the issue would be fixed but it has been like this for long time.

Yet whatever I do, whatever I turn off this pops up:

Content-Security-Policy: The page’s settings blocked the loading of a resource (default-src) at https://abs.twimg.com/responsive-web/client-web/bundle.Conversation.721fc4aa.js because it violates the following directive: “default-src 'self'”

The screenshot is from Zen, but it uses Firefox and the issue is the same in Firefox.

I have been using this wonderful browser since 2012, and it has been my default browser ever since. Recently, I've been facing an issue where I can't upload images, audio files, videos, or any other attachments on WhatsApp Web through this browser. To verify the problem, I tested WhatsApp on a different browser, and everything worked perfectly there.

I would appreciate your advice on how to resolve this issue. Please guide me on what steps I can take to fix the browser and restore normal functionality.

Has Firefox instituted a security setting that is interfering with commerce-related sites? Suddenly I can't log in to my credit union (gets stuck on "authentication" step), amazon.com (endless "transferring data" message during login attempt), and mutual fund sites (similar to amazon.com experience). These all are related to money/commerce. I've turned off Firefox's popup blocking and even explicitly allowed cookies for the sites. I did a Refresh to get rid of extensions that might be causing problems (even though there wasn't a problem a week ago on these sites). I've tried Firefox on a second computer for the credit union site and got the same behavior. Chrome has no problem with these logins, by the way.

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!

Facebook page fails to fully load often (not always) and in some occasions it load partially -instead of a picture it shows a blank box with a description of what it is supposed to be on the box.

Using other browser (Edge for example) loads the page fine in the affected Laptop and loading on an IPad using Firefox works fine too.

I have "flushed" the WI-Fi and "requested" a new IP for this computer and it is hard to tell if this solves the problem temporary or it is just the on-off nature of the problem.

In other occasions the page appears to load ok but the pull down menu (like notifications) are "blank" or it just appears to be loading and never navigate to the requested page.

In the sample below (image) is similar to the issue although in this case the page loaded after a few seconds. Note the missing information.
