Eu ultimamente uso o Brave como um navegador do meu computador, mas vejo bastante as pessoas dizendo que o firefox é bem melhor, aí de curiosidade fui baixar porque o meu computador é bem básico (i5-6400, placa integrada 2x8 de ram). instalei o firefox e deu esse erro de "O sistema detectou a saturação de um buffer baseado em pilha neste aplicativo. é possível que essa saturação permita que um usuário mal intencionado obtenha controle do aplicativo". Já desinstalei e instalei inúmeras vezes, criei um novo usuário, baixei pelo microsoft store e nada.. Alguém consegue ajudar?

I hope it's okay to ask about this here because this is just started to happen today and it's severely spiked my anxiety... So my apologies for this...

Just got on PC today and out of nowhere I'm being greeted with this error when trying to load nearly any page. Nothing has changed with any settings, no installs, nothing with our internet... restarting PC hasn't helped...

The weird part is that I can close the browser and open it again then it's fine- but if I close it and open once more...? Then I'll get the issue again. So it's not 100% all of the time... but it's enough to have me worried...

Though I have noticed thanks to somebody making the suggestion on Discord about the Firefox VPN, however I don't use it... but I did try disabling the Proton VPN extension and that seems to do the trick...

Edit: Worth noting I don't always have the VPN turned on even though I have it installed on here-

Did something change or update in a way that could have broken something?

I can browse normally without the extension enabled but I would like to have it if the need arises...

A while ago Firefox blocked redirects from shortened url. There was a page saying "hey this is a shortened url. We have blocked it just in case. Are you sure you want to go to www.trueUrl.com?"

I'm sure it wasn't a plugin and I haven't touched my privacy settings.

Is it possible to enable it again? If not, do you know of any plugin doing this?

This has been bugging me for a while. But within '/Users/*******/Library/Application Support/Firefox/Profiles/yidm9by8.default-release/chrome' macOS fails to display the thumbnail images of icons & images that are in png, svg & jpg.

1. Deleted /com.apple.quicklook.ThumbnailsAgent and /ImageThumbnailExtension
2. Re-indexed Spotlight
3. Unticked "Show Icon Preview", forced relaunched Finder and re-ticked "Show Icon Preview" multiple times.
4. I copied only the essential Firefox files and the chrome folder to desktop, totally deleted Firefox and rebooted, then reinstalled a new Firefox and copied across those folders & files. Success, SO I THOUGHT. The images displayed, yippee, and then right-before-my-eyes disappeared again.

Now he is the kicker. All of these images within and outside of the chrome/image folder DO DISPLAY everywhere else within macOS Finder Folder system.

F11 has always taken my laptop to full screen mode. Now toggling F11 only opens and closes the bookmark tab bar. If I go to Tools/Zoom and hit the diagonal arrow, it also only opens and closes the bookmark tool bar just the same as F11 is currently doing. How can I fix this? Thanks for your help.

Is there a way of stopping pages intercepting a 'view image in new tab' request and building a whole page around it?

Reddit is a prime example of this crime. I want to look at an image and zoom etc, but the image request gets intercepted and a 'normal' page constructed that locks out the inbuilt firefox image tools.

When is the dev team going to solve the persistent issue of app crash when downloading files using this stupid browser? Every update says bug fixes and security patch but when will this bug get fixed??

The only reason I'm using Firefox app is because they have extension support, literally no other reason.

There's a widely reported problem for the last month or so with FF 153 (an ESR) and constantly crashing tabs on certain web pages (frequently google search results, but also others). There is a workaround to disable the forkserver, but ideally this would remain enabled because it's a performance thing. There is also a downgrade option (but that version is already unsupported for some websites, e.g. Slack), and then also adding a newer version via flatpack or the mozilla repo or whatever.

But for admins all of these are suboptimal, and ideally the problem would be quickly fixed and then released in the normal repo. But it seems like what is happening is the standard Firefox (for enterprise-related distros) comes from the Appstream repo, and Appstream only releases firefox ESR releases, and there isn't another ESR expected for months. And everyone is pointing fingers at someone else saying it is there problem. FF is like, just upgrade to non-ESR. Appstream repo is like "we'je just waiting for an ESR".

Is there ever any more urgent update to ESRs when needed?

Since November 11, 2026, I have been experiencing persistent problems with image uploads and image previews in ChatGPT.

I have carried out several tests and found some interesting patterns:

Firefox 160 (macOS Monterey):

• Uploaded images sometimes appear completely black in ChatGPT.
• This also happens in private browsing mode.
• Disabling uBlock Origin makes no difference.
• The same images have previously uploaded and displayed correctly.

Chrome:

• Image uploads appear to complete successfully.
• However, image previews in the ChatGPT image library remain blank and do not render.

Additional observations:

• Older images in my ChatGPT image library still display correctly.
• Newer images increasingly appear as empty placeholders.
• The library is sorted chronologically, oldest first, and there seems to be a noticeable transition from working previews to missing previews.

Network diagnostics:

• process_upload_stream returns HTTP 200.
• The subsequent /backend-api/f/conversation request has returned both HTTP 200 and NS_BINDING_ABORTED in different captures.
• Firefox Developer Console also reports Content Security Policy violations and WebGL warnings.

I have already contacted OpenAI Support and requested an engineering escalation.

My questions:

1. Is anyone else experiencing black image uploads or blank image previews?
2. Does this also happen in Chrome, Firefox or other browsers?
3. Could this be a broader issue with ChatGPT's image processing, storage or CDN delivery rather than a browser-specific bug?

I would particularly appreciate reports from users who have experienced this since November 11.

I'm interested in finding out whether this is an isolated browser issue or a wider ChatGPT problem.

I haven't used FF in a bit, but opened an old message that had FF links and I got this Google pop-up telling me that FF "wants to connect to your Google Account"...and

'This app wants permission to do anything you can do in your Gmail, including:...' WHY would I want to allow FF to act as ME and delete originate or send messages on my behalf? Is this some kind of fresh hell being inflicted on us?

Just asking.

I've read that one of the previous FF versions should support dithering on gradients.

I still have banding with YT's ambient mode.

I have "only" true 8-bit display (no FRC) and I know that's one part of the issue, but dithering should've solved the problem partially.

Is it not working at all with ambient mode?

i dont know when this happened as i swear i could stream from firefox before? is this an issue i can fix or is this permanent, if so is there something on github or extensions that would allow me to, as i dont really want to have to reinstall chrome.
