Firefox Community Forum

Firefox was once the most popular browser in the world, but then Mozilla started releasing updates every week and became disgusting. Now Mozilla has a tiny piece of the market, they have essentially lost almost everything, but they continue to shit with updates like diarrhea, which most users do not need and it's impossible to refuse the annoying, ugly constant reminder about updates. I'm not even talking about the fact that after a refusal to update to a new version, there is a forced update to a new version without permission. So, why doesn't this company learn from its mistakes and become at least a little smarter?

Firefox will not run on my Apple Desktop any more. I have re-installed several times - still comes up "not responding" and I have to force quit.

I am running OS 12.7.5

I started up Firefox this morning and received to following message

XULRunner Error: Platform version '127.0.2 is not compatible....

i found this error on the internet, proposed solution, I uninstalled Firefox and found my profiles... NO WHAT DO I DO....?

Hello everyone,

support for Windows 7, 8 and 8.1 will end in September with the end of the ESR 115 branch. Corresponding support article

Is this still the current status or are there any plans to support the old Windows versions for a little longer?

Thanks and regards, Martin

I have just re-installed Windows10 on my pc. I assumed that once I had downloaded Firefox and then signed in I would have the same bookmarks and saved passwords. Is this a possibility? or am I expecting too much?

When I attempt to watch videos on YouTube, the playback is consistently choppy. This occurs regardless of the video’s quality setting, and it happens both on Wi-Fi and cellular data. The video frequently pauses to buffer, even though the loading bar indicates that the video has already buffered up to a certain point. Additionally, I notice a significant drop in video quality, and the screen sometimes freezes while the audio continues to play. The problem persists across different videos and channels, suggesting it is not specific to any particular content.

Since the last update (was executed today in my case 16-07-2024), firefox has been very slow and freezing and crashing. Also, somehow it is the only browser that can't handle yahoo finance new charts and keeps freezing....so many issues in a short span of time, please check. I have tried other browsers and things seem to work fine there, so, it is not my computer or OS.

I have used Firefox as my preferred web browser for years. Following an update a couple of weeks ago, Firefox no longer starts. Instead I get the following error message:

XUL Runner Error: Platform version '127.0.2 is not compatible with minVersion>=127.0.1 maxVersion<=127.0.1

My OS is Windows 10.

I would be most grateful for any advice on how to regain access to Firefox.

Please advise how to disable automatic updates on Firefox running on Linux Kubuntu. Solutions posted on mozilla.org do not work because stated disable options are not available(see screenshot). I have set app.auto.update to false in about:config but this does not disable updates. I have been repeatedly advised not to disable updates so I am aware of the so called risk. I am very tired of every update breaking a reliable browser and having to repair/fix/workaround each and every time. Please provide a viable solution.

I keep getting intrusive mozilla / Mcaffee advertising banners on my screen when firefox is open. avast won't stop them. It only affects my new dell laptop windows 11 computer. It looks like the code for firefox has been invaded. How do I block updates to firefox or get ride of the adds?

I have downloaded (or so I thought) the Firefox 115.13 in order to use Billpay via my bank. After several attempts, my bank keeps saying "Looks like you are using Firefox 78; update to..." Would love any help. Shan
