Firefox won't stay downloaded to my computer. I am having to download it multiple times, especially if my computer has updates.

On a separate note, when it does actually stay on my computer over night, it never keeps me signed in to my Firefox account. I have to log in to it daily to have my bookmarks and passwords.

Also, it never remembers the theme I have picked for it. I would love some advice on how to fix this.

I've read through a ton of articles, and I can't seem to find a fix.

My Firefox version is 86.0 on Mac. OS Version is 11.2.2 Big Sur.

I found that basically all color rendered in Firefox is more vibrant than Safari and Chrome, maybe Firefox doesn't handles color management right and renders sRGB in full P3 color space, lead to a over saturate color for almost every element on webpage.

Hopes firefox can fix this soon, I love the efficiency and privacy features on Firefox, This is the only bit I found a little uncomfortable.

You can test your browser here: https://cameratico.com/tools/web-browser-color-management-test/ if you have a P3 support Mac or Windows.

Firefox shows a blank white page for every tab and nothing seems to fix this. I cannot access the options menu, it simply won't open when I click it.

I have tried:

Opening it in the troubleshooting mode Refreshing firefox (resetting it to the default) Uninstall and reinstalling Uninstalling, removing any folders relating to firefox from appdata, and then reinstalling

Nothing works. It's still unusable, and I don't really want to use chrome or edge. Any help is appreciated.

I am just not sure if this is anything to be concerned with, i did a bunch of searches for firefox open ports, but couldn't find an answer

Everybody knows that google.com don't have any problems in latest Firefox builds, right?

Then why I have this HSTS on google from last week. It's blocking YouTube, Gmail, Calendar and other apps.

Pls help.

P.s. I don't have any issue with my 2nd laptop and my PC. Only on this device I'm using now.

I recently updated FireFox to it's new version and added add-ons. Usually, when an add-on gets added, it shows immediately on the top left on the toolbar. (in videos and articles). However it doesn't display on mine. I did some research and found another method: customize toolbar -> drag the add-on to the toolbar. That didn't work either because no add-ons displays when i enter customize toolbar. Instead, there's an add-ons icon to drag. Dragging it on the toolbar and clicking on it doesn't do anything. I also read that if the toolbar is full there would be a + icon and when i click on it add-ons shows up. (my toolbar is actually empty and i don't have a + icon). So yeah, i'm left with no solutions. Appreciate some help and suggestions.

When I try to print something from google drive it launches the firefox (?) printer dialogue. The I click next, and get this screen requiring me to download it before going to the HP printer dialogue. Can I skip this part, the downloads get so full!

Hello everybody!

I just updated my firefox to the newest version - and I absolutely hate the new design. Is there any way to "keep" the newest version, but have the older design?

I know that installing the version before the design got updated would be a possibility, but for various reasons I would like to avoid doing that - at least if there is any other option. If not, I'll just have to do that I guess.

Help would be very much appreciated!

Greetings

I recently purchased a Mac M1, coming from a Windows / Linux environment. After installing Firefox, it requires an icon on my desktop to run. Then, every time I reboot, Firefox no longer recognizes me. My pins, history, etc. are all gone and I have to re-organize everything again.

Can you please help?

So I got updated to version 89.0. I'm not entirely sure why we have to keep doing this. It looks different. Does it look better? Not really. Does it do something new that the previous version didn't do. Not that I can tell.

What it does do is scroll really badly. It's very jerky and it's giving me a headache. The previous version scrolled smoothly when I used the laptop's touch pad scroll section. (Like a wheel on a mouse but for a touch pad.)

I don't know why we have to keep "improving" things, without actually improving them and breaking what did work.

Is there any way to fix this? Other than Google Chrome?

I seem to remember that, prior to Firefox 89, there was a customize touch bar button in the menu, under Firefox. After updating to Firefox 89, I can't find the button anymore. I looked in the menu and in settings. I tried looking online.

Is it possible to set up Firefox so that during the night it uses a dark theme and during the day a light one? I haven't been able to find any dynamic theme setups

Hello, I had just recieved the new redesign of Firefox on my system and so far I am loving every bit of it.

However, I am a person that frequently opens many, MANY tabs and likes to keep them organized by draging them around on the tab bar. Since the new redesign I can no longer move my tabs around or open new windows by detaching tabs. Is this on purpose and supposed to have been a "feature" with the redesign? I have tried reinstalling firefox as well without success in fixing the issue.

Hello Guys, So yesterday I got the color selection thing popping up on my screen and I accidentaly selected white mode but I wanted dark mode. And now I don't know how to get back the color selection, because can't find it anywhere. Anyone know where I can change my color again?

First I was stuck in an upgrade loop where Firefox would ask me to restart to install the upgrade but then isn't upgraded on restart. So I manually downloaded latest version from the website and installed it. Now after installing I lost my current session (opened tabs). I have enabled sync so I can still see the synced tabs in my Firefox account under my device, but I don't know how to open all tabs from a particular device.

How do I open all synced tabs from a particular device in Firefox 89 on macOS 11.3.1?

Is there any way to change the time format in most recent visit in Bookmarks from am/pm to 24 hour?

Preferably without having to upload new version. I used Canadian one but after the newest update I tried to go back to older version, there was a bit of mess and long story short I loaded US version instead of Ca and trying to fix by with Ca version forced me to create new profile and it's still in am/pm.
