Firefox Community Forum

I have been using Firefox for my browser and have an account. Yesterday I clicked on the Firefox icon on my taskbar and it just opened with a blank screen. I need all of the information stored on my Firefox account. WHAT HAPPENED?? IT WILL NOT OPEN TO FIREFOX!!

During the past week I have been receiving 408 Request Time-out errors on a subscription website our organization uses. The vendor reports no changes to the site and no other customer complaints. All searches I've done point to my local browser or network setup, but I've cleared cache and cookies and it's not my network; I'm currently on vacation and getting the same errors 3000 miles from my home. It has worked fine for the past six months until last week.

I'll have to stop using Firefox if this continues. Please suggest some ideas why this suddenly started occurring and how I might fix it.

the following files couldn be attached outlook web Microsoft Outlook in firefox. Its files more 1 MByte. clearing the cache did not solve the problem. Outlook web in Microsoft Edge no problem with attach files Firefox version 133.0 (64-біт)

My connection to the Swiss bank UBS.COM is refused for connection to my account. UBS says it is a Firefox problem, because it accepts a Chrome connection!

I have the setting browser.search.openinnewtab and also browser.urlbar.openintab both set to true, but when I type a search into either the address bar or the search bar next to it, instead of opening a new tab, it puts that search into an already-open blank tab, if one is already open.

I often use blank tabs to separate my currently open tabs into groups by topic and whatnot, so it's incredibly annoying when the search bar takes over one of my adhoc 'separators' instead of opening a new tab like I want it to.

Is there a setting to force the search bar to always open a brand new tab, even if 'new tabs' are already open??

I never feel like webpages scale properly when I visit them. There is always content left off screen or I have to zoom out so much that the text is too small to read. Is there a setting I can change to affect this?

This webpage is particularly egregious: https://www.desktopmetal.com/products/shop

My Firefox Nightly version is: 135.0a1 (2024-11-26) (aarch64). My computer is a: MacBook Air (15-inch, M2, 2023) running macOS Sequoia (Version 15.1). I have been having these issues for a long time regardless of computer.

I have attached a picture of the labs settings I have enabled but I cannot see why any of them would affect this.

Got a new W11 computer and I know I've stopped it before.

I found https://support.mozilla.org/en-US/questions/1284577 on a search, but that didn't work and the answer is archived so I can't comment on it.

Where are the valid instructions?

Also, should I undo that? What other things might that now be doing?

I've encountered a bug in Mozilla Firefox where the browser becomes unresponsive when using Solid State Drives (SSDs), specifically PCI-E 3.0 SSDs with a 960GB M.2-110mm drive https://serverorbit.com/solid-state-drives-ssd/pci-e3-0-ssd/960gb-m-2-110mm. The issue seems to occur when multiple tabs are open, and the browser struggles to keep up with the data processing. Has anyone else experienced this issue, and are there any known fixes or workarounds?

As of v133 the system color is now longer shown at the top of the page. Everything at the top is now gray which I find to be very irritating. Please return the system color functionality.

Firefox flashes a white screen when loading a new page. This is a known issue. Is there a way to make it stop?

I see numerous people looking for answers (on mozilla, on stackoverflow, on superuser, on reddit, and on mozillazine), and I see no answers that work.

Is there a solution that works?

Does anyone know why Mozilla programs this in? (Is there a way to ask Mozilla directly?)

Firefox has been the only browser for me over the years, allowing customizations that free me from the frustrations of Chrome, Safari, et al. But why this flashbang, as kartana put it on reddit?

I'm not able to open any HTTP website on firefox (desktop and mobile) and it started about 2 months ago. So, is HTTP traffic not allowed anymore? I'm able to access HTTP over chrome, edge and safari, but firefox (regular and developer edition and ios version) are not working. It keeps loading for about 5 minutes then I see "ns_error_net_reset" in the console network tab.

also, https-only-mode is set to "don't enable" in the settings
