Firefox Community Forum

Hi, After updating to the latest version of Firefox on my laptop, I’ve noticed that the battery drains much faster than before. I haven’t changed any settings, but the browser seems to consume more power even with just a few tabs open.

I’ve already tried:

Restarting my laptop

Disabling unnecessary extensions

Clearing cache

But the issue is still there. Is there any specific setting or workaround to reduce battery usage in the new update?

Thanks in advance!

I thought that firefox would be more reliable than google chrome. For some reason, I am having now problems like accessing my youtube account and other things that worked fine before. There are other sites I can no longer access and I am wondering whether that has something to do with your service.

Hi,

I am trying to synchronise my web browser on my phone to my laptop, but when I try to do so using the QR code I get an error saying I need to use a Mozilla app to do it rather than my phone camera app (see attached)

I can’t find anywhere in my Firefox browser settings this app!

Help!!

"i am getting an er00r massage saying 'voise calling is not supported on this browser' whil trying to makea call on fasebook massenger using firefox.i have airedy tried restarting the browser, but it didn`t work. please help me fix this."

I have two separate Firefox accounts, with separate emails to log in and their own sets of bookmarks, passwords, etc. I want to merge all the data from both of those into a single profile of a single account under just one of the emails.

I'm pretty sure I've done this before, by: 1. Logging into account A and syncing. 2. Logging out of account A without deleting data. 3. Logging into account B and syncing. With the result that account B now contains all its original data plus all the data from account A.

But when I just tried to do this process now, at the point of logging in to account B I got the error "Account limit reached for this profile. This profile was previously synced to a different account. To keep your data organised and secure, each Firefox profile can only be synchronised to one account. To sign in using [account B], create a new profile."

I don't want to have separate profiles with the data from accounts A and B, I want it all merged into the same profile. How can I achieve this?

Tab groups work well with the standard tab bar, but when changing to vertical tabs, there is no clear way to expand the menu (aka hit the 'V' at the right of the tab bar for horizontal tabs) to see the tab group.

The only fix i found was to turn off vertical tabs, open the tab group, then turn on vertical tabs again.

You might be wondering why we lumped fractions and greatest common fractions together.
The fraction

The first time the inline table creates a new line second time inserts in fraction where it is (which is how I want it) How do I prevent it from forcing a new line?

I can submit posts on X using Chrome, but Firefox, for some reason, has cut off the portion of the posting box that contains the submit button and other edit features. It simply vanished as of March 10 2026.

I have attached screenshots showing FireFox vs Chrome.

I cleared cache and cookies to no avail. I have the latest Firefox version. 148.0 64 bit. Windows 11 operating system.

There used to be a much more useful interface for clearing specific browsing data (the landscape-oriented one). The new interface is far less detailed to the point of strictly limiting its functionality. There used to be a config setting ("privacy.sanitize.useOldClearHistoryDialog") that could toggle which interface to use, but as of an update in the last week (I've been away without a computer for a while), that toggle does nothing. Is there any other setting that can make this feature actually useful again?

I am writing the following sentence in html: <a href="https://www.users.no/ingehelland/Desktop/QDT_article.pdf">QDT_article</a>. Firefox refuses to open the file

I don't see the suggestions when I'm typing. It was the most visited site by me and firefox was autofilling it. Now I can see there's nothing in my history like it is the first time I use firefox. I haven't changed anything in firefox settings or system files etc. It's just got deleted. I'm a MAC user

Hi Team,

I am having issues logging in to my Firefox account to sync the browser.

"This profile was previously synced to a different account

To keep your data organized and secure, each Firefox profile can only be synced to one account. To sign in using [email removed]@aftc.co, create a new profile."

When I go to the all trails site, I get a blank page, with only the words, "Please enable JS and disable any ad blocker" I checked my settings, and my ad blocker in Firefox is disabled. I cannot figure out, in my settings, how to verify that my javascript is enabled.

i need to change my email since my old email go hacked, so i dont have access to my old email anymore. i still have access to my account since i am logged in on my phone and desktop. I have backup authentication codes if that helps. Codes are getting sent to my hacked email which i dont have access to.
