Firefox Community Forum

I created an account on an old PC, in the account it is visible as kos-work-note, now I am on a new kos-ltop, and there is no data at all in the browser, why is that?

W 11 May, 2025 update really made my computer unable to go online in any way and I had to restore. But FFox updates to have made it impossible to communicate. My phone has trouble s too. So, how do we make stick telephone permissions for, say: G Voice page https://voice.google.com/u/0/calls now? Thank you

Since the last update, I believe, because this error occurs constantly and with EVERY video. This is often, not always, the case immediately after updating FF. Now it was fine for a while, but now it's so bad that I'm having trouble watching YT videos properly. Reason: Browser open, logged in to YT. I click on a video to play - video opens, plays maybe 10 to 20 seconds, then playback stops spinning top, I also found out during the last glitch after update that if I switch the resolution briefly, higher or lower doesn't matter - important is to leave the current resolution and switch to another one. And oh wonder - immediately, instantly with the change, the video starts playing. If I wait for this - without doing anything myself, it sometimes takes 30 - 40 seconds for the video to start ... sometimes it just "hangs" ... This is extremely annoying - if it doesn't work, I have to switch browsers... What is also extremely annoying is that it occurs almost regularly after an update ... until the next one possibly, for unknown reasons, does not fix the error, but sometimes mitigates it. Now, however, the disruption/interruption is so massive and totally annoying that I'm thinking of switching. I'm just tired of it ...

When you right-click on a window thumbnail, a menu should appear, but instead the window thumbnail just disappears. The screenshots show 1) a Firefox mini-window 2) a mini-window that just disappeared when you right-click 3) a mini-window of any other program 4) the menu that appeared is as it should be Otherwise the browser works absolutely fine for a long time. But this problem causes a lot of inconvenience because I have 2 monitors.

windows 10 is up to date firefox is up to date (137.02 64 bit) dark theme

there is no bookmark sidebar button at the right of the address bar

I am running firefox in 5 windows with at least 7 tabs each every time i exit, reopen of update it i have more that 35 Bookmark LEFT Side Bars to close IF i have the patience to close all of them WHICH NEVER HAPPENS... (this is happening since too long, I am pissed off...)

I searched, tried a couple of "solutions" to no avail

Firefox Containers > Manage Containers > Remove [container]; message (modal, I think it's called?) pops up to say I have a tab open and do I want to proceed? I to up to the container icon upper-right, search for [container], click to open that page, then CTRL+W to close it. Then I try to Remove [container] again; fails. That container is still in the list, and still popping up a note that a tab is open in that container (no, I closed it).

I really like the Containers feature, AND it could use some improvement.

Unrelated, I'm open to help with proofreading; feel free to ask, or point me to a git where I could contribute. I'm not happy about the apparent erosion of privacy in Firefox, but it sure beats Google, Microsoft, Apple, etc.

When I first open Firefox from the icon in my taskbar the opening window says the following:

'Unable to connect Firefox can’t establish a connection to the server at 0.0.0.4. The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer’s network connection. If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.'

However this is only the first window, after that I can open a new tab in the same window without any problems.

I have uninstalled and reinstalled Firefox without avail. Can anyone help please?

I just downloaded firefox for the first time because Chrome disabled uBlocker. I have added uBlocker and 1Password as extensions, but neither of them are working on any webpage at all. I also can't pin extentions. I have restarted firefox and my computer several times. What do I do?

Hello,

as per description I noticed that firefox version 138 requires an ArrayBuffer as the argument of WebAssembly.compile() and doesn't allow anymore (like in 137) a SharedArrayBuffer, is this intended or it will be fixed in the future? Follows a simple test case. Kind reagards.

--- index.html --- <title>Example</title> <button onclick="testWasm()">Press to run wasm function (sum)</button> --- ---

--- sum.wat --- (to convert into .wasm using: wat2wasm sum.wat -o sum.wasm) (module (func $add (param $lhs i32) (param $rhs i32) (result i32) local.get $lhs local.get $rhs i32.add) (export "add" (func $add)) ) --- ---

I accidentally uninstalled firefox and need to recover passwords and bookmarks. Can this be done? I run an old dell latitude with Windows 10 and was trying to cleanup apps running in background at startup since it was running very slowly. At one point I saw 2 firefox icons. Uninstalled one and lost everything. Can you help me. Michael Evans

Ok for some reason any of my browsers tabs are crashing I just do whatever it is whether i search or watch movie and after some time 'Gah! your tab crashed' and it's pretty annoying, my discord happens to restart it self and I've exhausted literally anything from re-installing, deleting caches folders absolutely anything.

I've uploaded my latest 2 crashes and hopefully someone can read it and let m know about anything, Thanks in advance!

More frequently than I care to admit, I seem to close FF instances which I don't want to close (such as my connection to Whatsapp). I then miss important replies or questions. Of course I can reach out to 'History' and try to find the closed Tab or Window... But that takes time.

I'd suggest adding/removing a 'protection' flag to a tab (eg. on right-clicking), so that, on trying to close the tab, or close the window containing the tab, I get a warning...

When trying to do a search for a video in YouTube Studio, the search seems to freeze. Doing a similar search in Microsoft Edge works OK. This problem started happening several months ago. I've tried clearing the cache for YouTube pages.
