In dem Sie das update in der bisher genutzten Sprache (Deutsch) ausliefern. Der Versuch den Firefox V143 auf Deutsch umzustellen ist mit der Auskunft gescheitert das Firefox V143 nicht mit "deutsch" kann. Wäre gut wenn sie einen Pätsch nachschieben der den Firefox in Deutsch auftreten lässt.

Ubuntu - I use the SNAP version of Firefox - I generally have lots of tabs open but only use 5 or so of them and it's generally fine.... but when I am closing Firefox, it USES like 100% of the CPU and ALL of the RAM and ALL of the SWAP memory when closing.

This locks up the computer.

Sometimes it doesn't quite go all the way but I can watch it all happen in real time, using Task Manager - and that shows a solidwall of all resources occouring, when the close Firefox is run.

I am told by research via ChatGPT that this is a very real problem with the SNAP version and it's best to change to the Debian version, copy all the bookmarks etc., across and then uninstall the SNAP version.

It's rather disconcerting to have Linux crash because of this one app locking it up and frequently.

Chat GPT:

Is there a problem with Firefox Snap Version closing and using all the resources while doing so, which results in locking up the computer?

You're definitely not imagining it—there have been reports of Firefox's Snap version consuming excessive system resources (CPU, memory) and even causing lockups or hangs, particularly during closure. Here's what’s going on and how to mitigate it:

What’s Happening with Firefox Snap?

2. Browser Hangs or Locks the System on Close

On Linux (especially Ubuntu), users have reported that closing Firefox can lead to it hanging in memory, sometimes unresponsive and still consuming resources.

A stark example from Reddit illustrates the severity:
“About 50% of the time I open Firefox, it'll reach 100% CPU usage in about 30 seconds… PC completely unusable unless I shutdown.”

3. Known Wayland Sway Bug

On Wayland/Sway setups, reloading Sway while Firefox is open can trigger intense logging, causing high CPU use and an enormous syslog.
Fix: Set MOZ_DISABLE_WAYLAND_PROXY=1, or upgrade to FF 125 where the issue is addressed.

Alternative Approach

Many users, particularly on Ubuntu, opt out of Snap completely in favor of the .deb package or PPA builds. These alternatives often avoid these specific issues. Ask Ubuntu Reddit

Hello, hope you're having a nice day.

I'm encountering an issue in my web app: when typing a character with an accent (such as á, ä, etc.), the textarea clears out and becomes disabled, making it unusable for Spanish speakers. This behavior worked correctly until a few months ago. The application is built with Vaadin.

Below are the mozregression logs for this issue. The commit that first showed this behavior is a24b524f, worked fine upto 3b954f08.

The reported web site in bug 1910865 sets `HTMLInputElement.value` to the latest value explicitly at every `input` event except when during a composition. When it's in a composition, it stores the latest value at `input` events during the composition and set it at `compositionend` event listener.

Currently, Gecko dispatches the events as the following order at ending a composition: 1. `beforeinput` whose `isComposing` is `true` 2. `compositionend` 3. `input` whose `isComposing` is `false`

Therefore, if user chooses the commit string from the candidate list, the commit string is not notified by `input` event before the `compositionend`.

On the other hand, Chrome dispatch the events as the following order: 1. `beforeinput` whose `isComposing` is `true` 2. `input` whose `isComposing` is `true` 3. `compositionend`

I.e., no `input` event is fired after `compositionend` and there is no `input` event whose `isComposing` is `false`. This is handled in the spec issue [1], but not yet resolved.

Perhaps, we can dispatch redundant `input` event before `compositionend` event, i.e., 1. `beforeinput` whose `isComposing` is `true` 2. `input` whose `isComposing` is `true` 3. `compositionend` 4. `input` whose `isComposing` is `false`

This breaks the pair of `beforeinput` and `input`, but I guess it's not important for web apps especially for the redundant `input` event case.

Hi! Firefox now has two profile managers. The old one can be used so that I can open two Firefox instances with different desktop files on Linux with the "-P and --no-remote" command line flags. Is this also possible with the new profile manager in Firefox that came with version 138, which is similar to Chrome's? With Chrome this can be done with the "--profile-directory" command line flag. Can't find information about this. /Regards

Hi, mi machine runs Ubuntu Mate 24.04, kernel 6.14.0.29 and Firefox 141.0.3 . Starting from the end of last year, 2024, I get a strange situation: in Google Sheets I can invoke certain functions only in the range 5:00 am to midday, actually I never tried earlier. I asked for help to Google and we realized that the malfunction doesn't appear with Google Chrome browser or Brave. So I'm here to ask for support, how can I fix this?

On windows whenever you move a tab and nudge it out of the window, it instantly creates a new window for it, but on SteamOS desktop mode, instead it only creates a new window once you release the tab onto a blank desktop. This is causing a number of glitches for me, most notably if I release onto a desktop that already has an app, it will create a ghost tab or occupies the same position as a different tab making both of them unusable and I want to know how to change it to be more like Windows, or is this a Firefox specific thing in which case will switching to another browser fix the issue?

I am using firefox on ubuntu (firefox 142.0.1 (64-bit)) and using vertical tabs in the side bar. I recently started using the new(ish) feature of tab groups and I absolutely love it. I was using STG (simple tab groups) before and that fine, but this is way nicer. The only small annoyance I have, which could be a mistake on my side. Is that some of my tab groups are shortend seemingly randomly? If I for example make a group named "phone" it is visible like that, but after a couple of hours it goes to "ph...". I thought it may be sidebar width not being wide enough, but you can see in my screenshot that is not the case. Strangely if I make a new group it is always complete.

So I was wondering if I am missing a setting or config entry.

Thank you for reading and hope you have a great day!

how do I stop firefox from stealing focus?

How do I STOP this site: https://wise.com/login From stealing focus from what ever I happen to be doing. This is driving me absolutely flipping nuts! All the searches I've done tell me how to prevent popups or notifications or pages from clicked links from focusing, but none of these helps. I've someone could help before I'm completely bald from tearing my hear out, it'd be great.

Thanks M

Hi,

I have 3 devices with the same Firefox account : a phone, a work pc and a personal pc. I don't have bookmarks sync on any of my devices. From my phone I can access (read only) my bookmarks from both my pc. It seems I can't do the same from a pc to another. Am I missing something or is the feature not implemented?

Thanks

Здравствуйте, при скачивании плагина с интернета, скачивание происходит, полоска загрузки заполняется на 100%, но сам файл не скачивается, как будто зависает на этапе проверки. Ждал очень долго, так и не скачался
