Firefox Support Forum

Following approach to show video stream via Media Source Extensions (MSE) works well in Chrome, Edge, Opera but not in FireFox:

Media Source API

mediaSource = new MediaSource() sourceBuffer = mediaSource.addSourceBuffer(myCodec) sourceBuffer.mode = "sequence" sourceBuffer.addEventListener('updateend', function () { UpdateEndHandler(self); }, false) sourceBuffer.addEventListener('updatestart', function () { UpdateStartHandler(self); }, false)

and in the events UpdateStartHandler and UpdateEndHandler is processed the value of - sourceBuffer.buffered.end(0)

The problem is that FireFox often returns the same values for UpdateStartHandler and for UpdateEndHandler event which si not correct because into sourceBuffer.appendBuffer were appended real video data. Chrome, Edge, Opera returns two different values.

Please help.

While running Firefox browser in Windows10, every once in a while a 'sorry your Firefox has crashed' box pops up. Yet the browser is still running just fine. Any ideas?

I believe this started with 94.0.2 but could be 94.0.1. Looking at various things in Easysnews.com, for instance thumbnails, the title for that item used to change from blue (Unvisted Links) to brown (Visited Links) and keep the brown color until I exited Easynews. Now it does not. In another case, looking at my list of favorite groups, the group name will turn brown as long as my mouse is over it but it will not stick if I select that item.

I am not using system colors and Override the colors specified by the page with your selections above is set to Only With High Contrast themes. I tried the other two choices but they really created a mess.

I have also tried deleting any easynews cookies to no effect.

Major issues after opening Firefox this morning - an update resulted in ALL my data being deleted. Hundreds of passwords, bookmarks, etc all gone. Infuriating is an understatement. It is impossible to get in touch with a real person at Firefox to troubleshoot this - what on earth am I meant to do to resolve this!?!?!?!

Hello,

I downloaded firefox app on my android phone and noticed that the browser or pages are brown in color. I am not computer savvy so I don't exactly know how it arrived that way. But I love it and I would like to have it on my laptop.

I have vision problems and I am photo sensitive. I eyes hurt bad, so much that tears run down my face and my nose run while trying to use the computer. Is this brown screen available for laptop. If so how would I access it.

Thank you,

Hi I keep getting these error messages in Firefox. I uninstalled and reinstalled Firefox. It seemed to work ok after that, until I logged back in to Firefox a few minutes later and started getting this error again. I like Firefox but getting all these errors is really frustrating. I do not have these errors with other browsers. Any ideas? If not I will have to go to another browser.

When I use gmail in FFx some emails don't fully open and display their contents but they do when I use MS Edge browser. Office Depot/Office Max sales emails in particular just open to show the Office Depot name, with no content below it. But when viewed in Edge everything works- the email displays everything that's on sale.

Running ROCK SOLID Windows 7 SP 1 64 bit. Last week updated 64 bit FF from 88xx to 94.0.2. EVERYTHING was working fine with FF 88 except for videos on CNN.

After update when I right click in FF the small Context Menu freezes. Subsequent right clicks launches the same Menu. See attached image. When I mess around with scrolling they go away.

Also, when I'm going back and forth between a FF web page and a file in another app to cut and paste text or images, half of one or the other screens hang.

I'm an old geek and I did ALL of the recommendations including a complete clean uninstall and clean reinstall of FF 94.0.2... I've spent hours trying to solve the problem...

I'm having NO PROBLEMS with Chrome or Opera or any other SW on this PC.

BTW, DON'T EVEN SUGGEST GOING TO Windows 10 or 11. I have 10 but I use 7 on this PC for a lot of reasons.

Like I said, problems began after 94.0.2 update.

Regards,

Chas.

Hello,

When there is a form to fill out in Firefox, whenever I fill it out and press "refresh", the things that I wrote still stay there. However, I don't want it to do that, I want it to refresh the forms as if I am visiting the page from new. How can I make it so that Firefox does this? It is weird because it used to do this but now no longer does.

Ésta, es una sugerencia de implementación de funciones para el Firefox Daylight.

This is a feature implementation suggestion for Firefox Daylight.

Estoy convencido de que sería un gran avance el poder contar con una función automática activable/desactivable que lograra un "modo oscuro" durante la visita de cualquier página web.

I am convinced that it would be a great advance to have an automatic activated/deactivated function that achieves a "dark mode" during the visit of any web page.

Se trataría de una función similar a la que ya disponen algunos otros grandes Buscadores como, por ejemplo, pueda ser Opera...

It would be a function similar to that already available to some other large Search Engines, such as Opera...

De esta manera, Firefox también se sumaría a la corriente por la defensa de la salud visual al utilizar Internet.

In this way, Firefox would also join the trend for the defense of visual health when using the Internet.

Un guiño para cualquier otro ser humano inteligente: ésta misma página de Firefox para la escritura de mensajes, está de blanco riguroso y cegador. Y no es que lo blanco y brillante sea algo malo, es que hablamos de pantallas cargadas de luminosidad que agotan nuestra vista. "Negro sobre blanco" para describir la posibilidad de leer un texto sobre papel físico (un libro) es una cosa. "Negro sobre blanco" para captar la lectura de la imagen proyectada por una pantalla electrónica es otra cosa muy diferente. A mi juicio, demasiado diferente.

A nod to any other intelligent human being: this very Firefox page for writing messages, is in stark and blinding white. And it is not that white and bright is a bad thing, it is that we are talking about screens loaded with luminosity that exhaust our eyesight. "Black on white" to describe the ability to read a text on physical paper (a book) is one thing. "Black on white" to capture the reading of the image projected by an electronic screen is quite another thing. In my opinion, too different.

Es por esta razón por la que ruego que sean informados los ingenieros de Firefox sobre esta petición.

It is for this reason that I ask that Firefox engineers be informed about this request.

how do you copy the url in the address bar? there used to be a way at the right side of the address bar. It is not there anymore. How do you do this quickly? Sometimes the whole address does not show and it is hard to copy and paste.

Sign in...sign in...sign in.... What. I am signed in to my Firefox account, why the hell do I have to sign in, change my profile etc etc, to ask a question? I'm getting frustrated with Firefox, it's my goto browser but really, it's getting to be a piece of crap. Too many incompatible changes, with itself and it's extensions. I've changed settings, particular to Youtube, I use Youtube extensions, but regularly those settings are ignored. I'll change autoplay, pop out mini players, in-scroll video pop-outs etc, all to be off, but on the next video or page load, it's back. I get page not found for sites like Aliexpress. WTF is going on? I've cleared cache, I've reset settings and keep getting the same crap issues.

I posted a similar request here: https://mozilla.crowdicity.com/post/742615, because "Submit Feedback" link redirected me there. Maybe this is the right place for the feedback.

The release note of FF Ver:93 states this:"When available system memory is critically low, Firefox on Windows will automatically unload tabs based on their last access time, memory usage, and other attributes. This should help reduce Firefox out-of-memory crashes. Switching to an unloaded tab automatically reloads it."

This is something those of us with modest RAM (4GB, in my case) have been waiting for, for quite a while. But, FF continues to hog significant memory in spite of the claimed changes as above. I don't see any perceivable changes to my system performance thus far even a few days since the update. The issue, as you'd know better, elevated RAM usage invariably causes a continual spike in Paging, leading to excessive Disk (HDD) usage > resulting in an unresponsive system, which eventually ends up in a system freeze (in my case at least). The only way out being a hard power-down and restart of the system.

I have also set the "Content process limit" to 4 in the settings to no avail. We'd appreciate if you could configure FF behavior to adapt when system resources are low than wait for things to be critical.

I am regular viewer of New Zealand Herald, NZ newspaper but the front page does not display correctly with Firefox browser. The images and text overlap on the left side. I am using my win 10 x64 Pro laptop and installed the latest Win 10 x64 Firefox. The website address is nzherald.co.nz Please advise as I did not have this problem with other browsers. Regards - RG

Firefox updated and now pages don't load at all or take forever and then don't work properly. I've never had an issue until the update. I want to go back to the older version that actually worked. How do I go back to the last version?
