Firefox Support Forum

I've been experiencing a weird problem with Firefox after some update pushed somewhere in 2021, if I recall correctly. Firefox does not work no matter what. What I have figured out (accidentally) is that my mac's System Integrity Protection is tuned off / disabled. When I enable it back, Firefox works perfectly. Unfortunately, I can't keep SIP enabled due to software testing and apparently there is no way to bypass Firefox's SIP check.

Здравствуйте! Начиная с Нового года перестал открываться Mozilla Firefox на компьютере на Windows 10.Я несколько раз переустанавливал браузер, но он по-прежнему не открывается даже через запуск от имени администратора! Скажите, в чем может быть проблема и помогите в решении!

Very Frustrated that I downloaded this new version... All of my setting that I've meticulously set up/changed are back to the default settings. All my extension, especially my lastpass are gone. My toolbar has no icons that I previously had set up... WTF

I downloaded some custom fonts that are extremely stylized, so it works well for art but not so well for actually reading text.

For some reason, Firefox is now replacing the fonts on various websites with one of these fonts, despite having all of my Firefox font settings set to default.

I´m using Firefox since many, many years ago. Some days ago I have install this web browser in an old Desktop PC, a Compaq Presario, working with Windows 7 Professional x64, an Intel Core 2 Duo 6300 of 1,87 Ghz, 4 Mb of RAM, 1Gb ethernet adapter with a 1 Gb Router LAN ports and an Internet connection of 300 Mb. Using the same Internet speed test I have observed the following results in differents moments of a day:

Firefox Download speed 130 Mb Opera Download speed 210 Mb Microsoft Edge Download speed 220 Mb Google Chrome Download speed 270 Mb

Firefox can work faster (near the 300 Mb of the Internet provider) with newer Intel processors (Intel i7, for example), but with older Desktop PC its seem not possible. I hope this information can be useful for future developments to allow Firefox to work in a wide variety of Computers.

Thanks so much and Happy New Year to everyone.

I use Bank of America online banking and have for years. Yesterday, all of a sudden, Firefox stopped letting me input anything in the password field. This happened on 3 different computers, 2 running Windows 11 and 1 running Windows 10. The 2 running Windows 11 also use the Mozilla VPN. BofA online banking works fine in Edge and Chrome - this is only happening when I try to log on using Firefox.

build command just compiles everything. install command installs Firefox on local machine (for all users). package command creates an isolated all-in-one archive from which Firefox can be run (including all libraries, at least that what I think it is). I don't know what artifact command does, but I think it's not it. Is there any command that can produce .deb file (which can be easily installed in one command)? My only hope right now is to copy whatever mach install is doing (all necessary folders etc.) and bundle everything in a custom archive. The main problem is the ginormous size of 32 GiB after build is complete. (I can't archive that and use as a portable installer/builder, which indeed would be very convenient but the size…)

When visiting a website who's domain begins with "app." and requires a username and password to login.

I enter my username and password, I get "Username and password do not match"

I then go to google chrome and use the exact same login credentials and it works.

Is this a problem with Firefox not communicating properly with the "app." website?

CORS errors blocking a Custom SharePoint Web Part from communicating to the RSS Feed source to display on the SharePoint page ONLY on Firefox! Chrome and Edge displayed the web part contents but I got this CORS error with Firefox. My research has shown this is strict security settings from the RSS feed service provider but my company's non-technical staff insisted it was my web part that caused it.

Please inform me of any other way to make my web part display contents by ELIMINATING this Cors error on Firefox. Please see the attached image.

Hi, i am wondering if there is a cache setting maybe, or something that causes this behaviour: -Set a custom icon/link to a tile. -Reopen browser -Tile does not imediately show the custom icon.

I think it would make sense to cache these images and have them load up right away, but it seems it tries to get the image from the link at every start.

Am i doing something wrong?

Добрый день , меня зовут Даниил. уважаемая поддержка . Я пользуюсь браузером уже несколько лет . Mozila firefox on Mac. И мне он очень нравится . Сейчас я использую Macbook Air M1 / 8gb / SSD . 2020. Все всегда работало быстро. Хагружались страницы быстро даже при включенных плагинах . Но примерно неделю назад заметил , что стал очень долго загружать страницу YouTube. Очень долго , я открыл эту страницу в Safari - она открылась моментально. Я решил почистить кэш и куки . Это не помогло . Я отключил все плагины . это тоже не помогло . Я очистил браузер через настройки . Тоже не помогло . Я удалил и заново скачал браузер . и все равно долго открывает страницу youtube . Прошу вас помочт мне , что я могу сделать ? Чтобы я дальше с удовольствием пользовался любимым браузером .

Good afternoon, my name is Daniel. respected support. I've been using the browser for several years now. Mozila firefox on Mac. And I really like him. Right now I am using Macbook Air M1 / ​​8gb / SSD . 2020. Everything has always worked quickly. Pages loaded quickly even with plugins enabled. But about a week ago I noticed that it took a very long time to load the YouTube page. For a very long time, I opened this page in Safari - it opened instantly. I decided to clear the cache and cookies. It did not help . I disabled all plugins. that didn't help either. I have cleared the browser via settings. It didn't help either. I deleted and redownloaded the browser. and it still takes a long time to open the youtube page. Please help me, what can I do? So that I can continue to use my favorite browser with pleasure.

Make it easy to restore every last session always as a default.

DO NOT do updates during daytime hours, PERIOD. Everytime Firefox shuts down randomly its while I'm actively working and Firefox updates then does not restore my session. Sometimes I've temporarily had over a hundred tabs open (to capture URLS, photograph something on screen to easily look it up after shutting down the tabs). Anyway, this costs me hours lost in productivity. This is happening often and I cannot do this any longer. I've not been able to meet deadlines more than once because of Firefox's random shut downs. This is just like someone coming up to my computer and pulling the power cord of the socket, just to be an asshole.

Its not even crashing. Its being shut down for updates which are lowest of priorities while I'm working. Firefox is not for people who are working. Its for people who are playing and what they are doing is not crucial to anything. And that is still rude.

I have gigabit fiber and I just tried to upload about 40gb to gDrive on Firefox (which I recently switched to from Edge). It said it was going to take about 3 hours ....?!?!

I cancelled after 5 minutes and did the exact same file upload on Edge browser...the whole upload took about 12 minutes.

3 hours...vs...12 minutes

What is this? This alone destroys Firefox for me if it's unfixable

I am using a win 7 home premium 64 bit laptop Dell XPS. I cannot afford a new computer or as someone trained in computer graphics (before I became disabled) I would. After installing the latest moxilla firefox browser updat last night I shut down my computer as usual. Today upon trying to get my laptop to boot I started getting windows software validation errors. I had not done any software updates except that new firefox update so there is no question what caused the problem. I managed to get a temp resolution by using my last restore point. Now I love firefox as my preferred browser (99% of the time, but I am concerned that the validation errors will start again if I install the current update. Anyone else seen anything like this? Or have a fix?

I always keep my software including my antiviral up to date.

Not sure what data I could share, or if its even relevant) because I had to use a restore point to get my computer to validate my 100% genuine windows software. I dont know if either the raw data or report would even be helpful so providing both.

Hi,

I use text expander and google forms as a large part of my workflow, and whenever I need to write anything additional in the text that has been imported from text expander, the browser shifts the text entry screen to the top. I then cannot see anything above where I am typing.

I have added a Loom video below so you can better understand what I'm talking about. https://www.loom.com/share/2a95d5af9adb43709885cc12e4cd8185 Loom Video

I bought a new laptop and installed firefox on it. I tried accessing the gmail.com account but it keeps showing me this page https://support.google.com/accounts/answer/32050?hl=en. I have tried severally but can't access my gmail account.

How do I stop the "snap to grid" function when dragging pictures from the window to the desktop on Mac? whenever I drag a Picture to the desktop, it's like the "snap to grid" option on the computer is on. The pictures won't stack if i drag them to the exact same place. Ive checked every preference option on both the Mac computer and the Firefox settings but there is nothing about disabling it. The "snap to grid" function is disabled on the computer itself and images will stack if dragged from another browser like Chrome. It only does it with Firefox. Any help would be appreciated.

mi old computer worked with Firefox Mac OS X 10.15 and at that moment is being fixet..
