Hello, everyone,

I don't seem able to install Firefox on a Windows tablet (at least I think it's a tablet, it's an Asus Transformer Book, with a tablet screen and a detachable keyboard, anyway). Does anyone have any ideas why, please?

I should warn anyone before they read on that I am in no way techie, so helping me may be frustrating at times as I need advice/instructions etc spelled out really simply, as anything too technical is beyond me, I'm afraid.

So, anyone brave and/or patient enough to read on... I've bought the tablet secondhand, 'wiped' etc. It's an Asus T100HAN Processor: Intel(R) Atom(TM) x5-Z8500 CPU@ 1.44GHz 1.44GHz Installed memory: 2.00GB System type: 64-bit Operating System, 64-based processor Pen and touch: Full Windows Touch Support with 10 Touch Points

It's currently running Windows 10 Home, but I'm hoping to install Linux Mint on it, although it's only since I bought it that it's occurred to me that putting Linux on it might not be as straightforward as I thought, (ie I'm typing this on a laptop that came with Windows but on which I installed Linux Mint. "If Linux runs on this, it must run on anything that can handle Windows," I thought to myself before buying the tablet. But now I've realised that, eg, this laptop doesn't have a touchscreen, not does the screen have to rotate, which is the main reason for buying the tablet.)

That's sort of a digression, but might not be, as it explains why my priority right now is installing Firefox on the machine - so that even if it turns out I can't install Linux on it, at least I'll have Firefox rather than Edge or whatever.

So, in the Edge that came already on the machine, I accessed the official Mozilla page (despite getting several scary warnings from Edge about there being a problem with "this website's" security certificate, oh, and something about "Windows SmartScreen can't be reached at the moment") and downloaded Firefox. I went for the desktop version because that seemed more relevant than the Android or iOS versions. Then I've told it to "Run". The installer thing has come up and the little colour wave thing has happened with the icon in the taskbar (or whatever it's called). And then, after several minutes, I've got a message from Firefox Installer: "Hmm. For some reason, we could not install Firefox. Choose OK to start again." So I've clicked on OK, and the same thing has happened. Several times. And I've downloaded Firefox umpteen times as well, just in case there'd been an issue with that first download, only the same thing has happened, over and over again.

From the "about" thing, it looks like the 30GB or so of storage on the tablet, but about 10GB(!!!) is taken up by "system files to help Windows run properly. Your PC won't work without them."

Can anyone explain, please, what's going on, and what (if anything) I can do to get the wretched thing to allow me to install Firefox? I could just about cope if I can't get Linux, but no Firefox??? No, no no!

Thanks, Alice.

I have a HUGE problem with Firefox memory usage. Some open instances of firefox are taking anywhere from 600mb to 2.8gb of memory. Since firefox opens MANY instances even with only ONE active window, this very quickly uses all available memory (4gb) causing a full laptop crash.

More concerning is that CLOSING the worst instance of memory usage STILL leaves the single open page/tab open, so what exactly was the memory eating instance actually doing ???

I have included a screengrab of the many remaining instances of firefox in windows task manager AFTER closing the main culprit.

I have also included a screengrab of all the adblockers I use which I believed would limit unnecessary memory usage, but does not seem to be effective.

Many Thanks

My YouTube homepage is blank when I visit using Firefox (see attached screenshot). Here is a list of all of the fixes I have tried:

-Disabling all extensions and turning off Enhanced Tracking Protection (at the same time) -Clearing cache -Clicking 'forget this site' on YouTube in my browser history -Restarting my PC/Firefox -Refreshing Firefox profile (this worked, but the issue returned after an hour) -Changing my system theme to light mode -Launching Firefox in troubleshoot mode -Logging in on an incognito window (with the same result) -Probably some other things I'm missing (I tried pretty much every result I could find from looking up 'YouTube homepage is blank' and 'YouTube homepage not loading).

The issue only occurs on Firefox and only after I log in to YouTube. This has never occurred before. I checked to make sure my Firefox and YouTube settings are the same as they've always been.

YouTube videos load fine as long as I paste the direct link into the URL bar, but ONLY the video (no comments, recommended videos, likes/dislikes, description, etc...) and I can't take it out of theatre mode nor fullscreen it (fullscreening it just removes the top bar of the browser--the video itself still has black bars on the sides).

Sometimes when I reload the page, I see the following at the end of the URL: &ThemeRefresh=1. I don't know if that means anything.

I am using the Firefox app on Windows 11. I am not using a VPN. This issue is specific to YouTube and YouTube only.

Any help would be greatly appreciated. Thanks!

Hi. There is a new feature of Firefox that bothers me. It is when I drag tabs around the top, they try to group when I don't want them to. So I go to about:config and find the "browser.tabs.groups.enabled" key and set it to false. But when I restart Firefox, the change reverts. How do I fix this so the change stays?

I've already tried going to Menu->Help->More troubleshooting information->Profile Folder->Open folder, but there is no "user.js" file there. Do I have to do a Firefox reset to fix this? I hope not...

Note that I'm pretty sure that other settings that I change do not revert when I restart Firefox. Right now, it seems to be just this one about:config setting, unless the new version of Firefox reverts all manually changed about:config settings upon restart.

Thanx in advance for any help.

I'm afraid I cannot continue using Firefox, after the last change, since I can no longer keep my tabs open after closing a session, as I specified in the settings: "Open previous windows and tabs." Can someone help?

Firefox has stopped obeying target="_blank"

Started a month or so ago.

Take a look at Firefox target="_blank" problem for details.

There is not a topic in the dropdown list that remotely addresses this issue so I just selected Performance and Connectivity for the hell of it.

Can’t launch Firefox 3.5.19 on Linux Ubuntu When trying to run with:

./firefox

Terminal gives the following:

./firefox-bin: error while loading shared libraries: libdbus-glib-1.so.2: cannot open shared object file: No such file or directory

Hi. There is a problem with video playback when skipping through the video using a playback bar. The video (but not audio) freezes at the spot when one skippes to another part of the video and re-establishes after a while (not so short while) to the part of the video that is currently played. I'm using Linux Fedora.

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 ...

How do I get the YouTube homepage to load more recommended content like it usually does?

Right now when I access the homepage a small portion of recommended content is loaded followed by a loading icon that doesn't seem to load anything.

This morning I went to check my email on gmail, and google asked me to sign in again. Easy, I thought. I entered my account, and then google asked for my passkey. Until this morning this meant that on my mac it would ask me to place my finger on the right key on the keyboard. This morning it just froze firefox indefinitely. I then tried on Safari, and it worked as expected. I checked the version of firefox: it's 136.0.1. Obviously something changed (i.e. broke!) with the new version. Has anybody else experienced this? Any suggested fixes?

I tried to do the fix using userChrome.css but it just didn't work. Am I doing something wrong?

Also the fullscreen animation fix using the about:config settings doesn't work either.

Thanks in advance :3

-using FF for Android (latest official release) and 1password (latest release). 1password is selected as default password manager and I have disabled prompts for FF to manage and autofill passwords

-when visiting a site with a linked password, the 1password field comes up to fill the saved password, but after clicking, FF brings up a warning:

Fill anyway 1password can't verify the app or website should have access to your XXXXXX login.

Cancel Fill once

Clicking fill once will fill the password correctly most of the time, but this behavior didn't occur previously. Previously, the password would be filled without the extra Firefox prompt.

What I've tried and noticed -removing and reinstalling both FF and 1password, and clearing cache for both -changing default password manager to none and then back to 1password -occurs in regular mobile and "desktop" modes -started occurring maybe in the last month or so, and beforehand this wasn't a problem.

-this problem doesn't occur with other browsers -in the autofill section of FF, the "autofill in other apps" slider is set to off, and there is no way I can slide it on, however when I click on it, it shows that the default android password manager is 1password

Any thoughts or suggestions would be greatly appreciated!

Thanks!

When accessing Outlook (https://outlook.office.com) using Firefox ESR version 128.9.0 and attempting to download a file attached to an email, the string 'UTF-8' is automatically inserted at the beginning of the file name, which is causing issues. This phenomenon does not occur with other browsers such as Edge or Chrome.

Is there a way to solve this problem?

Hi- I'm trying to setup two step in Microsoft Authenticator. I scan in the QR code from the Mozilla settings and that appears to work. However when I copy the generated code from the app and try to enter it back into the settings in my browser it tells me the code is wrong and thus I can't setup two step. I've tried loads of different authenticator apps and none seem to work. Can you help please? Thanks- Adrian.

1. Whenever I open Firefox for the first time since boot, it crashes, and I have to click on it a second time for a window to actually show up. Once it shows up, it's forgotten all about the previous session - none of my tabs re-open, the window opens up maximized.

2. Whenever I close the last open window, my previous tabs are completely forgotten. Checking task manager reveals that there are 10 or 11 Firefox processes that are still running.

• I have a second Windows 11 device that DOESN'T exhibit any of these issues and works correctly. Closing Firefox does not leave any running processes around.
• "Open previous windows and tabs" is enabled in options.
• "Firefox will: Remember history" is set in the History options.
• Both devices are running Firefox 137.0.2 64 bit.
