Hi, Mozilla team I hope that you have a great day, straight to the point, my UI sometimes crashes or some components glitch or don't even work as it has to This is a video below slowed(I couldn't upload the video).

I am trying to migrate from a very old version of Firefox (v. 55) to the current one, but there is an app that is more helpful to me that all the other features combined. That is the "Tab Grouping" app that will not run in any version of FF higher than v. 55.

In my work, which often includes a tremendous amount of research, I need to be able to quickly go from one group of tabs to another. If I had to open all these sites manually, that would take the better part of the day and frankly I don't have near the mental capacity to remember the tremendous number of tabs. I have had a couple replies (Thanks!) to this question sometime back, but unfortunately none were even close in performance.

So, can anyone direct me to an app that will allow very quick movement from different sets of windows/tab groups (please see screen shots below)? Is there anyway that I can get this app to work in Legacy mode? I have several other old apps that work perfectly well in this mode.

Hi Mozilla Suport teams, i am currently using the mozilla for the developer version and the app runs flawlessly, and i love it. But i have some suggestion for the developer at mozilla to make a tab that can group the tab into a fresh tab like the google chrome has, and since i open so many tab in this browser, i would absolutely love it where the feature of grouping tab is available for me, so i can group them in name and leave it there, rahter than open up more than 10+ tabs in a window. Thank you so much

error text - " Firefox cannot verify application "

when I enter email and password on cocofax.net login, scrwen just sits

I had ~500 saved logins on Firefox prior to it updating to version 121.0 - now I have 15.

Firefox Lockwise app on iPhone still shows all my saved passwords.

How do I get these back and why have you deleted them?

How do I import the firefox passwords I saved as csv file from firefox into firefox. I am not importing from a different browser which is the only option offered. I'm importing from the newly created csv file as instructed by firefox.

Hello, I am a first-time user of Mozilla and need help using your browser for college, please. The college I attend uses the browser, and I am not familiar with it.

Thank you, Christopher

Hi, I've been using Firefox on all my devices for YEARS without any issues. However, as of recently, I had moved into a new apartment, and with that came a new internet connection, which was very slow since the beginning, but usable.

At first I had assumed that Firefox on my PC was loading websites more slowly because of my poor internet, which was partly the case - however, my laptop and Android phone were on the same network as the PC and were both much faster. So I assumed it had something to do with the differences between WiFi and Ethernet connections - the PC was plugged into the latter while the laptop and phone were using WiFi.

But then I noticed that Firefox was the only program with lacking speeds. Spotify loads video podcasts with no problem, Steam downloads are relatively fast (as much as my network allows), only Firefox took MINUTES to load a simple web site. For example, I tried opening Reddit on my PC to write this post, gave up, and am now writing it on my phone. The Reddit website is still loading on my PC as we speak.

I honestly don't know what could be causing this issue. I checked Task Manager, and Firefox isn't using any more resources than it normally would. I am also using the latest version, I just checked.

Any ideas or fixes? Even diagnosing the problem would go a long way.

Is it possible for a big tech company like Apple to release a web platform that is not compatible with Firefox? Firefox is not supported by Apple School Manager (https://school.apple.com) i.e. a web platform designed for educational institutions (PA). Is it legal? Is it possible to make a claim to EU institutions? Thank you

Blank Page when clicking on tracking link from UPS website, https://www.ups.com/track?loc=en_US How do I fix this ? Thanks

After the last couple of updates Firefox will not wrap words in view source screen(CTRL+U). This makes the info very difficult to read as most lines of code run off the screen. How do fix this? Thanks.

Hello, I want your help! Because I want to change the appearance of checkboxes to toggles without affecting the other checkboxes (like rounded checkboxes) using userChrome.css in Firefox.

I'm not friend with CSS, because I don't know much about programming. So, please write me a correct CSS code in a comment.

The attached screenshot will explain my demands:

I recently downloaded Tree Style Tab. I still see the horizontal tab bar. I would like to hide it. However, I have tried just about every answer I could find on Mozilla, Google, Reddit, and any other websites that offered solutions. Nothing has worked since the last update. This includes the "type in about:config, toggle to true, open profile folder, create userChrome.css file, copy and paste xyz code, save, and restart Firefox" route.

Any help would be greatly appreciated!

Often times when I open a new tab, I get a dot that goes back and forth and will not open the tab. This seems to happen if I don't use Firefox for a few minutes. It's like its trying to open but can't.

I was trying to troubleshoot a black screen of death issue with Windows10 that first started appearing after Firefox adopted the new Private Browsing icon. In the process of doing so, I tried every combination of Firefox settings imaginable. Nothing worked as far as Asus, Windows, or Firefox settings, rolling back/ updating various drivers, etc. So, I decided to refresh Firefox and when that did not work, I decided to uninstall and reinstall Firefox. I'm not sure if that worked as far as the original black screen of death issue is concerned because now Firefox no longer remembers my cookies and site data allowed exceptions (my only exceptions were my bank websites, which worked as expected until the uninstall/reinstall). I've tried selecting always use private browsing and always delete cookies and site data when Firefox is closed (my previous settings), but every time I close Firefox and return those three exceptions are missing. Any ideas would be most welcome. BTW, does anyone know how to use that folder Firefox puts on the home screen labeled "Old Firefox Data" because I was expecting there to be a .exe file to click on to reload all the previous settings in one fell swoop.
