Diễn đàn hỗ trợ Firefox

I wanted to use sync to transfer my tabs from my previous MacBook to my new MacBook. I reset the previous MacBook and now when I login to the new one, sync does not show any of my previous tabs.

I expect the back button to return to the previous page visited, but too often the button either doesn't respond at all or a right click is required to view the page history. Is there something I need to do get the original function of the back button that I thought was universal in most browsers?

Title. Whenever I open Firefox, the window will appear shortly after, but it will take around a minute for websites to load. This applies to both tabs from older sessions and opening new tabs. It doesn't matter whether I've just booted up, or if I've been running for half an hour. I've tried disabling all extensions, but that hasn't fixed anything. I am running Linux Mint 21.1 Cinnamon on my Gaming Laptop. Specs shouldn't be an issue. ANY HELP WOULD BE MUCH APPRECIATED!

I have run Firefox for years on up to 4 PCs at once, everything has always synced and screens all look the same. Recently one laptop lost the addon extension icons in the Firefox toolbar. They remain on all other installations. I have tried uninstalling Firefox and installing an earlier build, and also the latest Beta build with no luck. All extensions show as installed and activated. I have copied the Profile from another laptop. I have of course done a reset. Any other suggestions?

I have my setting to ask me what to do with files, pdf , whether open or download i have it all set to ask it asks , it opens them in firefox but still downloads them to my computer. i don't want them to download , i'm never sure if they are safe how i stop stop auto download This has only been in the last few updates this began

Hello,

we use firefox in our company and the requirement appeared to turn on the security setting "Delete cookies and sitedata when closing Firefox" due to our security guidelines.

I´ve already checked the "Enterprise Policy Generator" Plugin, but there is no such option. Is there a possibilty to check this option and block it for the user by the about:config page?

Thanks in advance, J.Stempel

I have a problem with buttons in google docs, buttons works but pictures of buttons are dissipated. I asked about this questions to the community, but nobody could help me. I can't find if I can to get help from technical specialists of mozilla company? Is there only this community? This is really huge problem for me, because I work a lot with google docs and if I don't solve this problem then I'll have to go to another browser, but I don't want to :(

In reference to my previous post ( https://support.mozilla.org/en-US/questions/1382198?page=1 ) I have noticed that the "jumping while scrolling" in the Facebook News feed has returned after a couple of months of proper behavior. Ver. 108.0.2 It's not as bad as it was but it seems to be getting worse.

Is the circus back in town?

Am I going to have to move back to Chrome again ?? >:-(

As of today (worked yesterday and previously), I cant access Youtube using Firefox with my ProtonVPN on. Chrome+ProtonVPN=yes Firefox+ProtonVPN=no Firefox withoutVPN=yes Can I fix this in Firefox settings or ProtonVPN settings. I have contacted both.

For the past week Firefox has been opening Youtube in dark when for the last decade I've been using light. Every time I change to light it works for that tab, if I open a new tab and load Youtube it opens in dark appearance. When I change to light and then click my avatar in the top right of Youtube it's still states I'm in dark when it's in light.

Why doesn't the light appearance stay? I've cleared cookies and that doesn't seem to work. It's also specific to Firefox, this doesn't happen in Microsoft Edge.

Alright first of all I already tried all the tipps about Proxy and basically anything network related. It also happened out of nowhere since I was using my computer the night before but when I tried opening Firefox the next day it wouldnt load any site, crashed if I tried too much or got really weird and even if it did load after a long time of trial and error it only lasted for a bit and didnt load fully either. I'm on version 108.0.2 as of the last time checking. Everything else seems to be updated as well especially since other browsers work perfectly fine. I also cant really click on much since as I said if I try too much it crashes or doesnt work as intended. I'll provide some pictures which might help the cash report just in case.

I'd also rather not try reinstalling everything since I have a lot of rather important tabs open and I dont wanna risk losing any of them since im not sure how well the Firefox sync. works in this case.

I've recently switched back to Firefox from Edge and have run into a frustrating issue.

When I try to print documents from Firefox, the "Color Mode" in the print settings is grayed out so I can't select B&W.

This same problem exists both on my MacOS laptop + my Windows 11 desktop. Additionally, they are connected to different printers on different networks. It also occurs whether I'm trying to print a PDF or anything else in Firefox.

Based on this, it appears Firefox is the culprit here.

Any ideas on how to fix this?

Firefox Version: 108.0

I pressed some button that is on the left side of the keyboard, I didn't see what it was, and after that my url bar for some reason has a space that leaves the text on the right after that

In the current Version of Firefox the input field is set to the wrong filetype if select an csv file.

Open with Chrome and Firefox. Chrome set the file type to text/csv Firefox to "application/vnd.ms-excel"

Working example open the consoel to see the output: https://codepen.io/GrizzlyStu/pen/YzjZjez

How are my bookmarks stored when synced between devices? Are my bookmarks encrypted as well as my passwords/credit card info? This is from the Mozilla page regarding encryption:

"Your encryption key remains a secret, only known to you and your authorized devices." and "We store your encrypted data on our servers so we can’t read it."

I just wanted to make sure this also applies to bookmarks before I import all of mine.

Thanks for any help!

Submitted a report after all these crashes, and I'm at a loss for how to troubleshoot this. If music isn't playing the browser seems fine, and I haven't changed any extensions between now and the last time I played music successfully without crashes. Guessing maybe a recent Firefox update happened?

Currently running Firefox 108.0 on PopOS 22.04 LTS with GNOME version 42.5 and using Wayland.

Submitted Report ID: bp-109245aa-a75f-4c81-8f9d-fec490230115

Looks like the crash is caused by a SIGSEGV / SEGV_MAPERR according to the report, but I don't know where to even begin looking into a cause of that.

Any help would be greatly appreciated.
