Diễn đàn hỗ trợ Firefox

Due to repeated issues over a week, I uninstalled Firefox days ago. Tried to Reinstall it repeatedly on same device several times. It was working before..BUT it keeps showing its downloaded on Settings but Firefox download page keeps showing "DOWNLOAD" Tried several times. Not my computer. Nothing works to resolve it.. Windows 11..

something apparently got corrupted in firefox.. i tried running update and i keep getting failed to update.. i have refreshed.. i have uninstalled and reinstalled ...nothing. i am sure there is a folder or file somewhere that is corrupted and i cannnot find it. because even when i uninstall and reinstall fresh. all my bookmarks are there .. how to i start a TRUE NEW install??

Hi so am using version 125.0.1 and on my windows 10 machine I can add custom Search Shortcuts (the Add button is present) but on my windows 11 machine, the same settings page the Add button is dissapeared... Is it a limitation for Windows 11 machines?

I've had an ongoing issue with Firefox now for several months since upgrading to windows 11. When I try to copy text, or images, url's or anything really that is supposed to go to the clipboard, it copies a blank text with no data instead. I can copy text and images from other programs and even paste them into text fields on Firefox but I can't copy from Firefox to anything else and it's frustrating.

I recently got forced into upgrading Outlook in windows and hated it so I started using Thunderbird and surprisingly, I have the exact same issue there as well.

I have tried: Running Firefox in safe mode (Shift + Left Click) Resetting Firefox Switching Back to default themes Disabling hardware acceleration Updating to the latest Beta Build (v126) Running Firefox Developer edition

I really want to get this fixed and working, I don't want to have to switch to another browser =/.

This has been happening for months now, on multiple devices (I have tried at least 3 different devices), and on multiple networks.

I have read the articles in here, but they just want me to check network configuration which is exactly the same for all browsers.

If I restart firefox it starts working again.

How can I prevent it from breaking randomly? This is the only browser having issues, I'm almost positive is some bug and not a configuration thing, given that it happens under multiple circumstances and devices, while Edge and Chrome simply keep working just fine.

There is no consistent repro I can give, afaik it is just random, at some point Firefox just decides to stop working and I have to restart it. This disrupts my work and browsing activities as I can lose progress on input forms and similar actions.

After just turning on my computer running Windows 10, I opened Firefox. I open 1 web site and noticed my computer showed a (16) prefix when loading Firefox. I opened the Task Manager and it showed that there were 15 instances of "firefox" running in the background. All showed a UAC Virtulization of "Disabled". But they also showed using 638.8MB of memory. I do not know whether these are necessary files that must run in the background or if the number of files indicates that my system has been hacked and someone else is in my system from outside. Any suggestions as to validity of these files running or how I might confirm that they should be running. I have noticed the number of excessive background files before but the number is never consistent which makes me fear I may have been hacked.

I already found many users asking the same, but they didn't get a reply.... at least I didn't see any.

I want to protect my password memory with a master password - fine. But in 99% of my time, I don't need to enter login data. Even worse, if FF starts on an "invisible" monitor, I cannot move the window.

Is there a way to have FF prompt only for the password if I attempt to log into a site ? ... it already does that when I cancel the start-up prompt.... so is there an "auto cancel at startup ?"

Today I completely uninstalled and reinstalled Firefox. Since doing this, the taskbar icon is not the same as it has always been.

It used to be that if I pinned Firefox to the taskbar, I would click on it and the default Firefox window would open. When the mouse was right-clicked, the icon showed there was a choice of the default Firefox window and an option for a privacy window I could choose. I did that frequently.

Now if I pin Firefox to the taskbar there is no privacy window option. If I pin the private browser to the taskbar, this becomes the default window with options for the non-private default browser available with a right mouse click.

I would like to know how to pin the default Firefox window to the taskbar and have the private window option show up when that icon is clicked please.

Thanks for any help provided with this issue.

I have to put my face within inches of the screen and strain to see the text in Firefox browser menus, tabs, and search bars. How do I adjust the font size?

I'm not a programmer. If I need to enter code please be pedantic about descriptions of how to do that.

I have an issue where I go to website and I get a message that the website is temporarily available. I cannot go to a different webpage for what URL I want. I believe this has to do with history. I suspect I can get past this by flushing the history. I can get to the website I want by using a different browser such as chrome. Ho do I fix this?

I am writing to report an issue I have encountered while using the Firefox browser. Specifically, I am unable to take screenshots on the website https://hescoebill.pk/hesco-mis/. This issue persists despite numerous attempts, and it seems to be unique to this particular website. Is there any other way to take screenshot of site? I really want to take a screenshot for personal reason. Is it not allowed from the site owner side or what?

Most of the time I cannot print my emails because an "add blocker" is installed. So now, I no longer use Firefox, since when I use Microsoft, I have no such problem.

I just got a chromebook! Details:

Device name: Lenovo Flex 3 12.2" chromebook, 8GB ram. Intel N100 Device code name: IP Flex 3 CB 12 (pujjo, version 123.15786.0) Firefox version: 124.0.2 (flatpak) OS version: Version 123.0.6312.112 (Official Build) (64-bit) Chrome: Version 123.0.6312.112 (Official Build) (64-bit)

When I watch a youtube video with chrome my cpu usage is 20-30% When I do the same with firefox my cpu usage is 50%

Running `about:support` and going into `webrender_compositor` I get the following errors under `env`: 1. Blocklisted by gfxInfo 2. Blocklisted; failure code 3. FEATURE_FAILURE_WEBRENDER_COMPOSITOR_DISABLED

I have set almost all these force renders = True and even granted gpu access to firefox flathub but still no difference in performance. I am asking now because I am just going in circles in the rabbit hole.

After years of accessing www.youtube.com with Firefox with no problem, the website is no longer accessible as of yesterday. When I point my browser to that URL, I get a screen with greyed out video previews, greyed out titles, greyed out account access and a search window that does not do anything. I can access YouTube just fine with Safari. I've cleared my cache. Please advise.
